Learning curve of transfemoral carotid artery stenting in the Vascular Quality Initiative registry. J Vasc Surg 2024; 80:138-150.e8. [PMID: 38428653 DOI: 10.1016/j.jvs.2024.02.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Revised: 02/05/2024] [Accepted: 02/07/2024] [Indexed: 03/03/2024]
Abstract
OBJECTIVE With the recent expansion of the Centers for Medicare and Medicaid Services coverage, transfemoral carotid artery stenting (tfCAS) is expected to play a larger role in the management of carotid disease. Existing research on the tfCAS learning curve, primarily conducted over a decade ago, may not adequately describe the current effect of physician experience on outcomes. Because approximately 30% of perioperative strokes/deaths post-CAS occur after discharge, appropriate thresholds for in-hospital event rates have been suggested to be <4% for symptomatic and <2% for asymptomatic patients. This study evaluates the tfCAS learning curve using Vascular Quality Initiative (VQI) data. METHODS We identified VQI patients who underwent tfCAS between 2005 and 2023. Each physician's procedures were chronologically grouped into 12 categories, from procedure counts 1-25 to 351+. The primary outcome was in-hospital stroke/death rate; secondary outcomes were in-hospital stroke/death/myocardial infarction (MI), 30-day mortality, in-hospital stroke/transient ischemic attack (stroke/TIA), and access site complications. The relationship between outcomes and procedure counts was analyzed using the Cochran-Armitage test and a generalized linear model with restricted cubic splines. Our results were then validated using a generalized estimating equations model to account for the variability between physicians. RESULTS We analyzed 43,147 procedures by 2476 physicians. In symptomatic patients, there was a decrease in rates of in-hospital stroke/death (procedure counts 1-25 to 351+: 5.2%-1.7%), in-hospital stroke/death/MI (5.8%-1.7%), 30-day mortality (4.6%-2.8%), in-hospital stroke/TIA (5.0%-1.1%), and access site complications (4.1%-1.1%) as physician experience increased (all P values < .05). The in-hospital stroke/death rate remained above 4% until 235 procedures. Similarly, in asymptomatic patients, there was a decrease in rates of in-hospital stroke/death (2.1%-1.6%), in-hospital stroke/death/MI (2.6%-1.6%), 30-day mortality (1.7%-0.4%), and in-hospital stroke/TIA (2.8%-1.6%) with increasing physician experience (all P values <.05). The in-hospital stroke/death rate remained above 2% until 13 procedures. CONCLUSIONS In-hospital stroke/death and 30-day mortality rates after tfCAS decreased with increasing physician experience, showing a lengthy learning curve consistent with previous reports. Given that physicians' early cases may not be included in the VQI, the learning curve was likely underestimated. Nevertheless, a substantially high rate of in-hospital stroke/death was found in physicians' first 25 procedures. With the recent Centers for Medicare and Medicaid Services coverage expansion for tfCAS, a significant number of physicians would enter the early stage of the learning curve, potentially leading to increased postoperative complications.

Abstract
Transcarotid artery revascularization (TCAR) has risen as a promising minimally invasive intervention for high-risk patients with favorable anatomy. TCAR's noninferiority to carotid endarterectomy regarding stroke is reliant on its flow reversal technology and lack of aortic arch manipulation. We present the case of a 79-year-old man with a chronically occluded inferior vena cava who safely underwent staged bilateral TCAR for bilateral high-grade carotid artery stenosis. Although chronic inferior vena cava occlusion alters flow mechanics, we suspect that any pressure gradient facilitating retrograde flow from the carotid artery to the femoral vein provides neuroprotective benefits.

Clinical outcomes of transcarotid artery revascularization vs carotid endarterectomy from a large single-center experience. J Vasc Surg 2024; 79:1402-1411.e3. [PMID: 38320692 DOI: 10.1016/j.jvs.2024.01.213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 01/24/2024] [Accepted: 01/29/2024] [Indexed: 03/03/2024]
Abstract
BACKGROUND Transcarotid artery revascularization (TCAR) has been practiced as an alternative for both carotid endarterectomy (CEA) and transfemoral carotid artery stenting, specifically in high-risk patients. More recently, the Centers for Medicare and Medicaid Services expanded coverage for TCAR in standard surgical risk patients if done within the Society for Vascular Surgery Vascular Quality Initiative TCAR surveillance project. A few registry studies (primarily from the Society for Vascular Surgery Vascular Quality Initiative) compared the early and up to 1-year outcomes of TCAR vs CEA or transfemoral carotid artery stenting. There is no large single-center study that reported late clinical outcomes. The present study compares intermediate clinical outcomes of TCAR vs CEA. METHODS This study retrospectively analyzed collected data from TCAR surveillance project patients enrolled in our institution and compare it with CEA patients done by the same providers at the same time period. The primary outcome was combined perioperative stroke/death and late stroke/death. Secondary outcomes included combined stroke, death, and myocardial infarction, cranial nerve injury (CNI), and bleeding. Propensity matching was done to analyze outcome. Kaplan-Meier analysis was used to estimate freedom from stroke, stroke/death, and ≥50% and ≥80% restenosis. RESULTS We analyzed 646 procedures (637 patients) (404 CEA, 242 TCAR). There was no significant difference in the indications for carotid intervention. However, TCAR patients had more high-risk criteria, including hypertension, coronary artery disease, congestive heart failure, and renal failure. There was no significant differences between CEA vs TCAR in 30-day perioperative stroke (1% vs 2%), stroke/death rate (1% vs 3%; P = .0849), or major hematomas (2% vs 2%). The rate of CNI was significantly different (5% for CEA vs 1% for TCAR; P = .0138). At late follow-up (2 years), the rate of stroke was 1% vs 4% (P = .0273), stroke/death 8% vs 15% (P = .008), ≥80 % restenosis 0.5% vs 3% (P = .0139) for CEA patients vs TCAR patients, respectively. After matching 242 CEAs and 242 TCARs, the perioperative stroke rate was 1% for CEA vs 2% for TCAR (P = .5037), the stroke/death rate was 2% vs 3% (P = .2423), and the CNI rate was 3% vs 1% (P = .127). At late follow-up, rates of stroke were 1% for CEA vs 4% for TCAR (P = .0615) and stroke/death were 8% vs 15% (P = .0345). The rate of ≥80% restenosis was 0.9% for CEA vs 3% for TCAR (P = .099). The rates of freedom from stroke at 6, 12, 18, and 24 months for CEA vs TCAR were 99%, 99%, 99%, and 99% vs 97%, 95%, 93% and 93%, respectively (P = .0806); stroke/death were 94%, 90%, 87%, and 86% vs 93%, 87%, 76%, and 75%, respectively (P = .0529); and ≥80% restenosis were 100%, 99%, 98%, and 98% vs 97%, 95%, 93%, and 93%, respectively (P = .1132). CONCLUSIONS In a propensity-matched analysis, both CEA and TCAR have similar perioperative clinical outcomes. However, CEA was superior to TCAR for the rates of late stroke/death and had a somewhat lower rate of ≥80% restenosis at 2 years, but this difference was not statistically significant.

Abstract
BACKGROUND Ischemic stroke and disability caused by carotid artery stenosis have always been worldwide problems. At present, carotid endarterectomy (CEA) and transfemoral carotid artery stenting (TFCAS) have been commonly used to treat carotid artery stenosis. Recently, transcarotid artery revascularization (TCAR) seems to be another option. METHODS We searched PubMed and Embase to find literatures comparing TCAR with TFCAS and CEA. The primary outcomes were stroke, myocardial infarction (MI), transient ischemic attack (TIA), death, cranial nerve injure (CNI), and operative time. Secondary outcomes were stroke, death, MI in the elderly; cost; radiation; and entry site complication. RESULTS Initial search of the literature included 165 articles, of which 12 studies were chosen in the end. These studies demonstrated high technical success rate of TCAR. Patients who received TCAR had lower risks of death, stroke/death and less radiation exposure compared to TFCAS. In meta analysis, the risk of stroke was significantly lower in TCAR group than TFCAS (OR 0.63; 95%CI 0.47-0.85). And there was no significant difference in TIA and MI. TCAR was associated with shorter operative time, lower risk of CNI and less blood loss compared to CEA. In older patients, the effect of TCAR was significantly better than that of TFCAS. CONCLUSION TCAR is associated with a lower risk of perioperative stroke compared to TFCAS. TCAR is also associated with shorter operative time, lower risk of CNI and less blood loss compared to CEA. TCAR may be a promising treatment option besides TFCAS and CEA.

Abstract
BACKGROUND Transcarotid artery revascularization (TCAR), using interoperative flow reversal is a unique, hybrid operation utilized in treating critical carotid artery stenosis. Over the past decade, TCAR has been increasingly used to treat asymptomatic carotid artery disease and has a similar risk profile to traditional carotid endarterectomy. Postoperative length of stay (LOS) has a significant impact on cost-effectiveness and quality outcomes in this expanded setting. The objective of this study is to develop a multivariate regression model to identify key preoperative variables and their impact factor on LOS after TCAR for asymptomatic carotid artery stenosis. We hypothesized that high-risk preoperative patient factors historically identified in carotid endarterectomy would similarly impact LOS after TCAR. METHODS A multi-institution, retrospective study of all adult patients undergoing TCAR with flow-reversal for intraoperative neuroprotection was performed using the Society for Vascular Surgery Vascular Quality Initiative (VQI) from January 2016 to August 2021. Patients with prolonged preoperative hospitalization (preoperative LOS ≥1 day) were excluded to enhance the capture of carotid artery stenosis as the index admission. Univariate analysis was done on preoperative factors against LOS using nonparametric statistical tests. A multivariate model was then constructed using a negative binomial regression. The study population was split into 80% "training" data for model formulation and 20% "test" data for model validation. RESULTS Thirteen thousand four hundred eighty-three patients undergoing TCAR for asymptomatic carotid stenosis met the study's inclusion criteria with a median postoperative LOS of 1.82 days. Factors in VQI found to have a significant effect on LOS and retained in the multivariate model were lesion type (restenosis versus atherosclerotic), age, gender, chronic obstructive pulmonary disease, preoperative beta blocker, calcific lesion burden, hypertension status, and race (P < 0.05). The model accurately predicted LOS after TCAR within 1 day for 86.04% and within 2 days for 94.51% of patients in the test population. CONCLUSIONS This large-scale analysis from 2016 to 2021 spans a considerable expansion in the practice of TCAR for asymptomatic carotid disease. All preoperative variables shown to significantly increase the postoperative LOS were derived from the VQI data set. As LOS is a measure of health-care efficiency and cost-effectiveness, this model can be used to identify patients at risk for increased postoperative LOS. It has the potential to be incorporated into a patient/physician decision support tool to optimize resource planning and patient selection for elective TCAR.

Seven years of the transcarotid artery revascularization surveillance project, comparison to transfemoral stenting and endarterectomy. J Vasc Surg 2024:S0741-5214(24)01227-8.

Abstract
OBJECTIVE This study utilizes the latest data from the Vascular Quality Initiative (VQI), which now encompasses over 50,000 transcarotid artery revascularization (TCAR) procedures, to offer a sizeable dataset for comparing the effectiveness and safety of TCAR, transfemoral carotid artery stenting (tfCAS), and carotid endarterectomy (CEA). Given this substantial dataset, we are now able to compare outcomes overall and stratified by symptom status across revascularization techniques. METHODS Utilizing VQI data from September 2016 to August 2023, we conducted a risk-adjusted analysis by applying inverse probability of treatment weighting to compare in-hospital outcomes between TCAR vs tfCAS, CEA vs tfCAS, and TCAR vs CEA. Our primary outcome measure was in-hospital stroke/death. Secondary outcomes included myocardial infarction and cranial nerve injury. RESULTS A total of 50,068 patients underwent TCAR, 25,361 patients underwent tfCAS, and 122,737 patients underwent CEA. TCAR patients were older, more likely to have coronary artery disease, chronic kidney disease, and undergo coronary artery bypass grafting/percutaneous coronary intervention as well as prior contralateral CEA/CAS compared with both CEA and tfCAS. TfCAS had higher odds of stroke/death when compared with TCAR (2.9% vs 1.6%; adjusted odds ratio [aOR], 1.84; 95% confidence interval [CI], 1.65-2.06; P < .001) and CEA (2.9% vs 1.3%; aOR, 2.21; 95% CI, 2.01-2.43; P < .001). CEA had slightly lower odds of stroke/death compared with TCAR (1.3% vs 1.6%; aOR, 0.83; 95% CI, 0.76-0.91; P < .001). TfCAS had lower odds of cranial nerve injury compared with TCAR (0.0% vs 0.3%; aOR, 0.00; 95% CI, 0.00-0.00; P < .001) and CEA (0.0% vs 2.3%; aOR, 0.00; 95% CI, 0.0-0.0; P < .001) as well as lower odds of myocardial infarction compared with CEA (0.4% vs 0.6%; aOR, 0.67; 95% CI, 0.54-0.84; P < .001). CEA compared with TCAR had higher odds of myocardial infarction (0.6% vs 0.5%; aOR, 1.31; 95% CI, 1.13-1.54; P < .001) and cranial nerve injury (2.3% vs 0.3%; aOR, 9.42; 95% CI, 7.78-11.4; P < .001). CONCLUSIONS Although tfCAS may be beneficial for select patients, the lower stroke/death rates associated with CEA and TCAR are preferred. When deciding between CEA and TCAR, it is important to weigh additional procedural factors and outcomes such as myocardial infarction and cranial nerve injury, particularly when stroke/death rates are similar. Additionally, evaluating subgroups that may benefit from one procedure over another is essential for informed decision-making and enhanced patient care in the treatment of carotid stenosis.

Abstract
OBJECTIVE Patients with chronic kidney disease (CKD) are considered a high-risk population, and the optimal approach to the treatment of carotid disease remains unclear. Thus, we compared outcomes following carotid revascularization for patients with CKD by operative approach of carotid endarterectomy (CEA), transfemoral carotid artery stenting (TFCAS), and transcarotid arterial revascularization (TCAR). METHODS The Vascular Quality Initiative was analyzed for patients undergoing carotid revascularizations (CEA, TFCAS, and TCAR) from 2016 to 2021. Patients with normal renal function (estimated glomular filtration rate >90 mL/min/1.72 m2) were excluded. Asymptomatic and symptomatic carotid stenosis were assessed separately. Preoperative demographics, operative details, and outcomes of 30-day mortality, stroke, myocardial infarction (MI), and composite variable of stroke/death were compared. Multivariable analysis adjusted for differences in groups, including CKD stage. RESULTS A total of 90,343 patients with CKD underwent revascularization (CEA, n = 66,870; TCAR, n = 13,459; and TFCAS, n = 10,014; asymptomatic, 63%; symptomatic, 37%). Composite 30-day mortality/stroke rates were: asymptomatic: CEA, 1.4%; TCAR, 1.2%; TFCAS, 1.8%; and symptomatic: CEA, 2.7%; TCAR, 2.3%; TFCAS, 3.7%. In adjusted analysis, TCAR had lower 30-day mortality compared with CEA (asymptomatic: adjusted odds ratio [aOR], 0.4; 95% confidence interval [CI], 0.3-0.7; symptomatic: aOR, 0.5; 95% CI, 0.3-0.7), and no difference in stroke, MI, or the composite outcome of stroke/death in both symptom cohorts. TCAR had lower risk of other cardiac complications compared with CEA in asymptomatic patients (aOR, 0.7; 95% CI, 0.6-0.9) and had similar risk in symptomatic patients. Compared with TFCAS, TCAR patients had lower 30-day mortality (asymptomatic: aOR, 0.5; 95% CI, 0.2-0.95; symptomatic: aOR, 0.3; 95% CI, 0.2-0.4), stroke (symptomatic: aOR, 0.7; 95% CI, 0.5-0.97), and stroke/death (asymptomatic: aOR, 0.7; 95% CI, 0.5-0.97; symptomatic: aOR, 0.6; 95% CI, 0.4-0.7), but no differences in MI or other cardiac complications. Patients treated with TFCAS had higher 30-day mortality (aOR, 1.8; 95% CI, 1.2-2.5) and stroke risk (aOR, 1.3; 95% CI, 1.02-1.7) in symptomatic patients compared with CEA. There were no differences in MI or other cardiac complications. CONCLUSIONS Among patients with CKD, TCAR and CEA showed rates of stroke/death less than 2% for asymptomatic patients and less than 3% for symptomatic patients. Given the increased risk of major morbidity and mortality, TFCAS should not be performed in patients with CKD who are otherwise anatomic candidates for TCAR or CEA.

Yei KS, Janssen C, Elsayed N, Naazie I, Sedrakyan A, Malas MB. Long-term outcomes of carotid endarterectomy vs transfemoral carotid stenting in a Medicare-matched database. J Vasc Surg 2024; 79:826-834.e3. [PMID: 37634620 DOI: 10.1016/j.jvs.2023.08.118] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 08/14/2023] [Accepted: 08/22/2023] [Indexed: 08/29/2023]
Abstract
BACKGROUND Carotid endarterectomy (CEA) is associated with lower risk of perioperative stroke compared with transfemoral carotid artery stenting (TFCAS) in the treatment of carotid artery stenosis. However, there is discrepancy in data regarding long-term outcomes. We aimed to compare long-term outcomes of CEA vs TFCAS using the Medicare-matched Vascular Quality Initiative Vascular Implant Surveillance and Interventional Outcomes Network database. METHODS We assessed patients undergoing first-time CEA or TFCAS in Vascular Quality Initiative Vascular-Vascular Implant Surveillance and Interventional Outcomes Network from January 2003 to December 2018. Patients with prior history of carotid revascularization, nontransfemoral stenting, stenting performed without distal embolic protection, multiple or nonatherosclerotic lesions, or concomitant procedures were excluded. The primary outcome of interest was all-cause mortality, any stroke, and a combined end point of death or stroke. We additionally performed propensity score matching and stratification based on symptomatic status. RESULTS A total of 80,146 carotid revascularizations were performed, of which 72,615 were CEA and 7531 were TFCAS. CEA was associated with significantly lower risk of death (57.8% vs 70.4%, adjusted hazard ratio [aHR], 0.46; 95% confidence interval [CI], 0.41-0.52; P < .001), stroke (21.3% vs 26.6%; aHR, 0.63; 95% CI, 0.57-0.69; P < .001) and combined end point of death and stroke (65.3% vs 76.5%; HR, 0.49; 95% CI, 0.44-0.55; P < .001) at 10 years. These findings were reflected in the propensity-matched cohort (combined end point: 34.6% vs 46.8%; HR, 0.53; 95% CI, 0.46-0.62) at 4 years, as well as stratified analyses of combined end point by symptomatic status (asymptomatic: 63.2% vs 74.9%; HR, 0.49; 95% CI, 0.43-0.58; P < .001; symptomatic: 69.9% vs 78.3%; HR, 0.51; 95% CI, 0.45-0.59; P < .001) at 10 years. CONCLUSIONS In this analysis of North American real-world data, CEA was associated with greater long-term survival and fewer strokes compared with TFCAS. These findings support the continued use of CEA as the first-line revascularization procedure.

Abstract
Transcervical carotid artery revascularization has emerged as an alternative to carotid endarterectomy and transfemoral carotid artery stenting. We present four cases for which we believe transcervical carotid artery revascularization was the only option to treat the lesions. Each case presented with specific technical challenges that were overcome by intraoperative planning that allowed for safe deployment of the Enroute stent (Silk Road Medical) with resolution of each patient's stenosis.

Abstract
Background This study aimed to assess intraoperative cerebral hemodynamic responses and embolic events during transcarotid artery revascularization via transcranial Doppler, near-infrared spectroscopy, and bispectral index monitoring. Methods Twelve patients (7 males, 5 females; mean age: 72.8±9.0 years; range, 63 to 91 years) undergoing transcarotid artery revascularization with simultaneous transcranial Doppler, near-infrared spectroscopy, and bispectral index monitoring were analyzed in this retrospective study between September 2017 and December 2019. The mean flow velocity and pulsatility index of the middle cerebral artery, alongside near-infrared spectroscopy and bispectral index values, before flow reversal, during flow reversal, and after flow reversal phases were investigated. The presence and frequency of high-intensity transient signals were recorded to evaluate embolic incidents. Results Significant reductions in middle cerebral artery mean flow velocity were noted during flow reversal (40.58±10.57 cm/sec to 20.58±14.34 cm/sec, p=0.0004), which subsequently returned to and exceeded baseline values after flow reversal cessation (53.33±17.69 cm/sec, p=0.0005). Near-infrared spectroscopy (71±4.4% to 66±6.2%) and bispectral index (45.71±8.5 to 40.14±8.1) values mirrored these hemodynamic changes, with notable decreases during flow reversal, and recoveries after flow reversal. The highest concentration of high-intensity transient signals was observed during stent deployment, signifying a critical embolic phase. No perioperative neurological complications or other significant adverse events were documented. Conclusion Transcranial Doppler, near-infrared spectroscopy, and bispectral index effectively monitor cerebral hemodynamics and embolic potential during transcarotid artery revascularization, providing real-time data crucial for optimizing perioperative management. These findings underscore the clinical value of multimodal monitoring in improving patient outcomes in transcarotid artery revascularization procedures.

Abstract
This systematic review and meta-analysis compared trans-carotid artery revascularization (TCAR) as an alternative approach to carotid endarterectomy (CEA) in patients with carotid artery disease. An electronic search was conducted using PubMed, Scopus, and Cochrane databases including comparative studies with patients who underwent either TCAR or CEA. This meta-analysis is according to the recommendations of the PRISMA statement. Eight studies met our eligibility criteria, incorporating 7,606 and 7,048 patients in the TCAR and CEA groups, respectively. Thirty-day mortality (odds ratio [OR]: 0.94, 95% confidence interval [CI]: 0.56-1.56, P = .81) and stroke (OR: 0.92, 95%CI 0.70-1.22, P = .57) were similar between the two groups, with low heterogeneity. The odds of myocardial infarction (OR: 1.79, 95% CI: 1.18-2.71, P = .01) and cranial nerve injury were significantly higher in patients undergoing CEA compared with TCAR (OR: 4.11, 95% CI: 2.59-6.51, P < .001). The subgroup analysis according to symptomatic pre-intervention status revealed no statistically significant difference regarding 30-day mortality (symptomatic OR: 0.91, 95% CI: 0.40-2.07, P = .82, asymptomatic OR: 0.93, 95% CI: 0.46-1.86, P = .83) and stroke (symptomatic OR: 0.88, 95% CI:0.47-1.64, P = .68, asymptomatic OR: 0.93, 95% CI: 0.64-1.35, P = .70). TCAR offers an alternative treatment for patients with carotid artery stenosis with comparable to CEA mortality and stroke rates during a 30-day post-operative period.

Outcomes following carotid revascularization for stroke stratified by Modified Rankin Scale and time of intervention. J Vasc Surg 2024; 79:287-296.e1. [PMID: 38179993 DOI: 10.1016/j.jvs.2023.10.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 10/12/2023] [Accepted: 10/13/2023] [Indexed: 01/06/2024]
Abstract
OBJECTIVES The relationship between baseline Modified Rankin Scale (mRS) in patients with prior stroke and optimal timing of carotid revascularization is unclear. Therefore, we evaluated the timing of transfemoral carotid artery stenting (tfCAS), transcarotid artery revascularization (TCAR), and carotid endarterectomy (CEA) after prior stroke, stratified by preoperative mRS. METHODS We identified patients with recent stroke who underwent tfCAS, TCAR, or CEA between 2012 and 2021. Patients were stratified by preoperative mRS (0-1, 2, 3-4, or 5) and days from symptom onset to intervention (time to intervention; ≤2 days, 3-14 days, 15-90 days, and 91-180 days). First, we performed univariate analyses comparing in-hospital outcomes between separate mRS or time-to-intervention cohorts for all carotid intervention methods. Afterward, multivariable logistic regression was used to adjust for demographics and comorbidities across groups, and outcomes between the various intervention methods were compared. Primary outcome was the in-hospital stroke/death rate. RESULTS We identified 4260 patients who underwent tfCAS, 3130 patients who underwent TCAR, and 20,012 patients who underwent CEA. Patients were most likely to have minimal disability (mRS, 0-1 [61%]) and least likely to have severe disability (mRS, 5 [1.5%]). Patients most often underwent revascularization in 3 to 14 days (45%). Across all intervention methods, increasing preoperative mRS was associated with higher procedural in-hospital stroke/death (all P < .03), whereas increasing time to intervention was associated with lower stroke/death rates (all P < .01). After adjustment for demographics and comorbidities, undergoing tfCAS was associated with higher stroke/death compared with undergoing CEA (adjusted odds ratio, 1.6; 95% confidence interval, 1.3-1.9; P < .01) or undergoing TCAR (adjusted odds ratio, 1.3; 95% confidence interval, 1.0-1.8; P = .03). CONCLUSIONS In patients with preoperative stroke, optimal timing for carotid revascularization varies with stroke severity. Increasing preoperative mRS was associated with higher procedural in-hospital stroke/death rates, whereas increasing time to-intervention was associated with lower stroke/death rates. Overall, patients undergoing CEA were associated with lower in-hospital stroke/deaths. To determine benefit for delayed intervention, these results should be weighed against the risk of recurrent stroke during the interval before intervention.

Abstract
BACKGROUND Long-term follow-up (LTFU) following carotid revascularization is important for post-surgical care, stroke risk optimization and post-market surveillance of new technologies. METHODS We instituted a quality improvement project to improve LTFU rates for carotid revascularizations (primary outcome) by scheduling perioperative and one-year follow-up appointments at time of surgery discharge. A temporal trends analysis (Q1 2019 through Q1 2022), multivariable regression, and interrupted time series (ITS) were performed to compare pre-post intervention LTFU rates. RESULTS 269 consecutive patients were included (151 pre-intervention, 118 post-intervention; mean 71 ± 12 years-old, 39% female, 77% White). The overall LTFU rate improved (64.9%-78.8%; P = 0.013) after the intervention. After controlling for patient factors, procedures performed after the intervention were associated with increased odds of being seen for 1-year follow-up (OR: 2.2 95%CI: 1.2-4.0). Quarterly ITS analysis corroborated this relationship (P = 0.01). CONCLUSIONS Time-of-surgery appointment creation and automated patient reminders can improve LTFU rates following carotid revascularizations.

Abstract
BACKGROUND Transcarotid Artery Revascularization (TCAR) using the ENROUTE system (Silk Road) has been proposed as a safe and effective alternative to both carotid endarterectomy (CEA) and transfemoral carotid artery stenting (TF-CAS). Two large registries (ROADSTER 1 and ROADSTER 2) have shown that TCAR has acceptable/low rates of perioperative stroke/death. This study will analyze the 30-day perioperative and 1-year clinical outcomes from a single-center. PATIENT POPULATION AND METHODS This is a retrospective analysis of prospectively collected data from SVS/VQI TCAR surveillance project (TSP) of 100 consecutive patients (102 TCAR procedures) done in our institution. These procedures were done for high-risk patients for CEA, which included anatomical (previous CEA, high cervical lesion, neck radiation, stoma, arch type, etc.), physiological (CHF, severe coronary artery disease, COPD on O2 therapy, etc.) and combined anatomical/physiological reasons. These procedures were done by vascular surgeons after receiving the appropriate training. The perioperative stroke, death, and MI rates were analyzed. Kaplan Meyer analysis was used to estimate rate of freedom from stroke/death and the incidence of ≥50% and ≥80% in-stent restenosis at 1 year. RESULTS 100 consecutive high-risk patients for CEA included: 38% anatomical, 44% physiological, and 18% combined anatomical and physiological reasons. The mean age was 72.5 years (range 52-90 years). Indications for TCAR were 34% for symptomatic lesions (TIA/stroke) and 66% for asymptomatic lesions. Mean ipsilateral treated stenosis was 80.4%. Contralateral ≥50% stenosis/occlusion was present in 31% of patients. Technical success rate was 100%. 92% had pre-stenting PTA and 26% had post-stenting PTA. The mean flow reversal time was 8.5 min (range 3-26 min). The 30-day perioperative stroke rate was 2.9% (1/67, 1.5% for asymptomatic patients), the stroke/death rate was 2.9%, and stroke/death and MI rate was 3.9% (4/102). Other perioperative complications included cranial nerve injury 3/102 (2.9%), carotid artery dissection (2%), and major hematoma (necessitated operation evacuation) (5.9%). Freedom from stroke rates and stroke/death rates at 1 year were: 90% and 89%. Freedom from ≥50% and ≥80% in-stent restenosis rates at 1 year were 82% and 90%, respectively. None of these restenosis were symptomatic except two (2/13). Freedom from reintervention rate at 1 year was 98%. CONCLUSION Although the perioperative events were somewhat higher than what has been reported in previous registries, TCAR for patients who are high-risk for CEA has a low perioperative stroke and stroke/death rates with satisfactory outcome at 1 year. Further long-term data is probably needed to verify long-term outcome.

Abstract
OBJECTIVE Transcarotid artery revascularization (TCAR) is a relatively recent development in the management of carotid artery occlusive disease, the utilization of which is becoming more prevalent. This study aims to evaluate the timing, prevalence, and types of hemodynamic instability after TCAR. METHODS We performed a retrospective review of all TCAR procedures performed at two tertiary care academic medical centers within a single hospital system from 2017 through 2019. Demographics, comorbidities, preoperative patient factors, procedural details, and postoperative data were collected. Patients were assessed over 24 hours postoperatively for stroke, death, myocardial infarction (MI), and hemodynamic instability at 3, 6, 9, 12, and 24 hour intervals. Hemodynamic instability was defined as any vital sign abnormality which required pharmacological intervention with antihypertensive, vasopressor, and/or anti-arrhythmic agents. The incidence and timing of postoperative complications and hemodynamic instability were recorded. RESULTS During the study period, 76 patients 80 TCAR procedures. Out of 80 procedures, 64 (80.0%) were receiving home antihypertensive medication and 28 (35.0%) were symptomatic lesions preoperatively. Intraoperatively, one patient (1.3%) received atropine, 26 (32.5%) received glycopyrrolate, 76 (95%) underwent predilatation, and 16 (20.0%) underwent postdilatation. Postoperatively, a total of 22 cases (27.5%) required medication for acute control of blood pressure or heart rate, which reached a peak of 19 patients (23.8%) within the first 3 hours, and tapered to nine patients (11.3%) by the 24 hour mark. A total of three patients (3.75%) required initiation of pharmacological management after the three-hour mark. Six patients (7.5%) underwent stroke code workup, 4 (5.0%) of whom were confirmed to have stroke on CT. Average time to neurologic event was 3.9 hours. No patients experienced MI or death. Median ICU and hospital days for unstable patients were two and three, respectively, compared to one and one for stable patients. CONCLUSIONS Hemodynamic instability is common after TCAR and reliably presents at or before postoperative hour 3. Hypo- followed by hyper-tension were the most common manifestations of hemodynamic instability. Regardless, unstable patients and stroke patients were more likely to require longer periods of time in the ICU and in the hospital overall. This may have implications for postoperative ICU resource management when deciding to transfer patients out of a monitored setting. Further study is required to establish relationships between pre- and intra-operative risk factors and outcomes such as hemodynamic instability and/or stroke. At present, one should proceed with careful evaluation of preoperative medications, strict management of postoperative hemodynamics, and clear communication among team members should all be employed to optimize outcomes.

Wu WW, Yadavalli SD, Lu JJ, Cheng JJ, Liang P, Dansey K, Stangenberg L, Wyers MC, Hamdan AD, Schermerhorn ML. Discrepancies in clavicle-to-carotid bifurcation length measurements for transcarotid artery revascularization using different imaging modalities. J Vasc Surg 2023; 78:1439-1448.e2. [PMID: 37657687 DOI: 10.1016/j.jvs.2023.08.124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 08/18/2023] [Accepted: 08/23/2023] [Indexed: 09/03/2023]
Abstract
OBJECTIVE Transcarotid artery revascularization (TCAR) has emerged as an effective method for carotid artery stenting. However, anatomic eligibility for TCAR is most often limited by an inadequate clavicle-to-carotid bifurcation length of <5 cm. Preoperative clavicle-to-carotid bifurcation distances may be underestimated when using conventional straight-line measurements on computed tomographic angiography (CTA) imaging. We therefore compared clavicle-to-carotid bifurcation lengths as measured by straight-line CTA, center-line CTA, and intraoperative duplex ultrasound (US), to assess potential differences. METHODS We conducted a single-center, retrospective review of consecutive TCAR procedures performed between 2016 and 2019 for atherosclerotic carotid disease. For each patient, we compared clavicle-to-carotid bifurcation lengths measured by straight-line CTA, center-line CTA using TeraRecon image reconstruction, and intraoperative duplex US with neck extension and rotation. We further assessed patient and imaging characteristics in individuals with a ≥0.5 cm difference among the measurement methods. In particular, common carotid artery (CCA) tortuosity, defined as the inability to visualize the entire CCA from clavicle to carotid bifurcation on both a single coronal and sagittal imaging cut, was examined as a contributing factor for these discrepancies. RESULTS Of the 70 TCAR procedures identified, 46 had all three imaging modalities available for review. The median clavicle-to-carotid bifurcation length was found to be 6.4 cm (interquartile range [IQR], 5.4-6.7 cm) on straight-line CTA, 7.0 cm (IQR, 6.0-7.5 cm) on intraoperative duplex US, and 7.2 cm (IQR, 6.5-7.5 cm) on center-line CTA (P < .001). Patients with a ≥0.5 cm difference between their straight-line CTA and either their intraoperative duplex US or center-line CTA measurements were more likely to have tortuous CCAs (60.0% vs 19.1%; P = .01; 51.4% vs 0.0%; P = .01). There were no notable differences in age, gender, prior neck/cervical spine surgery, or neck immobility among these individuals. In patients with tortuous CCAs, duplex US and center-line CTA measurements added 1.0 cm (IQR, 0.6-1.5 cm) and 1.1 cm (IQR, 0.9-1.6 cm) more in length than straight-line CTA measurements, respectively. There was a strong linear correlation between the additional lengths provided by duplex US measurements and those provided by center-line CTA measurements for each individual within the tortuous CCA group (r = 0.83). CONCLUSIONS The use of straight-line CTA during preoperative planning can underestimate the clavicle-to-carotid bifurcation lengths in patients undergoing carotid revascularization, particularly in those with tortuous CCAs. Both duplex US performed with extended-neck surgical positioning and center-line CTA provide similar and longer carotid length measurements, and should be utilized in patients with tortuous carotid vessels to better determine TCAR anatomic eligibility.

Abstract
Objective With the recent expansion of the Centers for Medicare and Medicaid Services (CMS) coverage, transfemoral carotid artery stenting (tfCAS) is expected to play a larger role in the management of carotid disease. Existing research on the tfCAS learning curve, primarily conducted over a decade ago, may not adequately describe the current effect of physician experience on outcomes. This study evaluates the tfCAS learning curve using VQI data. Methods We analyzed tfCAS patient data from 2005-2023. Each physician's procedures were chronologically grouped into 12 categories, from procedure counts 1-25 to 351+. Primary outcome was in-hospital stroke/death rate; secondary outcomes were in-hospital stroke/death/MI, 30-day mortality, and in-hospital stroke/TIA. The relationship between outcomes and procedure counts was analyzed using Cochran Armitage test and a generalized linear model with restricted cubic splines, validated using generalized estimating equations. Results We analyzed 43,147 procedures by 2,476 physicians. In symptomatic patients, there was a decrease in rates of in-hospital stroke/death (procedure counts 1-25 to 351+: 5.2% to 1.7%), in-hospital stroke/death/MI (5.8% to 1.7%), 30-day mortality (4.6% to 2.8%), in-hospital stroke/TIA (5.0% to 1.1%) (all p-values<0.05). The in-hospital stroke/death rate remained above 4% until 235 procedures. Similarly, in asymptomatic patients, there was a decrease in rates of in-hospital stroke/death (2.1% to 1.6%), in-hospital stroke/death/MI (2.6% to 1.6%), 30-day mortality (1.7% to 0.4%), and in-hospital stroke/TIA (2.8% to 1.6%) with increasing physician experience (all p-values<0.05). The in-hospital stroke/death rate remained above 2% until 13 procedures. Conclusions In-hospital stroke/death and 30-day mortality rates post-tfCAS decreased with increasing physician experience, showing a lengthy learning curve consistent with previous reports. Given that physicians' early cases may not be included in the VQI, the learning curve was likely underestimated. With the recent CMS coverage expansion for tfCAS, a significant number of physicians would enter the early stage of the learning curve, potentially leading to increased post-operative complications.

Abstract
OBJECTIVE Carotid endarterectomy (CEA) remains the gold standard procedure for carotid revascularization. Transfemoral carotid artery stenting (TFCAS) was introduced as a minimally invasive alternative procedure in patients who are at high risk for surgery. However, TFCAS was associated with an increased risk of stroke and death compared to CEA. BACKGROUND Transcarotid artery revascularization (TCAR) has outperformed TFCAS in several prior studies and has shown similar perioperative and 1-year outcomes compared with CEA. We aimed to compare the 1-year and 3-year outcomes of TCAR versus CEA in the Vascular Quality Initiative (VQI)-Medicare-Linked [Vascular Implant Surveillance and Interventional Outcomes Network (VISION)] database. METHODS The VISION database was queried for all patients undergoing CEA and TCAR between September 2016 to December 2019. The primary outcome was 1-year and 3-year survival. One-to-one propensity-score matching (PSM) without replacement was used to produce 2 well-matched cohorts. Kaplan-Meier estimates, and Cox regression was used for analyses. Exploratory analyses compared stroke rates using claims-based algorithms for comparison. RESULTS A total of 43,714 patients underwent CEA and 8089 patients underwent TCAR during the study period. Patients in the TCAR cohort were older and were more likely to have severe comorbidities. PSM produced two well-matched cohorts of 7351 pairs of TCAR and CEA. In the matched cohorts, there were no differences in 1-year death [hazard ratio (HR)=1.13; 95% CI, 0.99-1.30; P =0.065]. At 3-years, TCAR was associated with slight increased risk of death (HR=1.16; 95% CI, 1.04-1.30; P =0.008). When stratifying by initial symptomatic presentation, the increased 3-year death associated with TCAR persisted only in symptomatic patients (HR=1.33; 95% CI, 1.08-1.63; P =0.008). Exploratory analyses of postoperative stroke rates using administrative sources suggested that validated measures of claims-based stroke ascertainment are necessary. CONCLUSIONS In this large multi-institutional PSM analysis with robust Medicare-linked follow-up for survival analysis, the rate of death at 1 year was similar in TCAR and CEA regardless of symptomatic status. The slight increase in the risk of 3-year death in symptomatic patients undergoing TCAR is likely confounded by more severe comorbidities despite matching. A randomized controlled trial comparing TCAR to CEA is necessary to further determine the role of TCAR in standard-risk patients requiring carotid revascularization.

Abstract
OBJECTIVES Transcarotid artery revascularization (TCAR) has become more prevalent as a treatment modality for carotid stenosis. Many centers perform TCAR without any adjunctive neuromonitoring, for example, somatosensory-evoked potential (SSEP) and electroencephalogram (EEG). METHODS We present a case of transcarotid artery revascularization (TCAR) performed with concomitant somatosensory-evoked potential (SSEP) and electroencephalogram (EEG) neuromonitoring in the setting of concerning intraoperative angiographic images. RESULTS TCAR was undertaken for a 58 year-old man presenting with symptomatic left carotid stenosis and right ICA occlusion. Based on his comorbidities, pre-existing conditions, and the need for dual antiplatelet therapy, TCAR was offered as an alternative to standard carotid endarterectomy. Intraoperatively, following stent delivery, no flow was appreciated through the carotid stent or distal ICA. Neuromonitoring remained stable and was reassuring for distal ICA spasm with no-reflow phenomenon. The patient tolerated the procedure well and has had no stent-related complications through 10 months of follow-up. CONCLUSION This case highlights the utility of neuromonitoring with TCAR as an adjunct to intraoperative decision-making in the setting of suspected internal carotid artery (ICA) vasospasm versus thrombosis after stent delivery.

Abstract
Atherosclerotic carotid artery disease has been well studied over the last half-century by multiple randomized controlled trials attempting to elucidate the appropriate modality of therapy for this disease process. Surgical techniques have evolved from carotid artery endarterectomy and transfemoral carotid artery stenting to the development of hybrid techniques in transcarotid artery revascularization. In this article, the authors provide a review of the available literature regarding operative and medical management of carotid artery disease.

Abstract
OBJECTIVE We sought to quantify the percent calcification within carotid artery plaques and assess its impact on percent residual stenosis and rate of restenosis in patients undergoing transcarotid artery revascularization for symptomatic and asymptomatic carotid artery stenosis. METHODS A retrospective review of prospectively collected institutional Vascular Quality Initiative data was performed to identify all patients undergoing transcarotid artery revascularization from December 2015 to June 2021 (n = 210). Patient and lesion characteristics were extracted. Using a semiautomated workflow, preoperative computed tomography head and neck angiograms were analyzed to determine the calcified plaque volume in distal common carotid artery and internal carotid artery plaques. Intraoperative digital subtraction angiograms were reviewed to calculate the percent residual stenosis post-intervention according to North American Symptomatic Carotid Endarterectomy Trial criteria. Peak systolic velocity and end-diastolic velocity were extracted from outpatient carotid duplex ultrasound examinations. Univariate logistic regression was performed to analyze the relationship of calcium volume percent and Vascular Quality Initiative lesion calcification to percent residual stenosis in completion angiograms. Kaplan-Meier analysis examined the relationship between calcium volume percent and in-stent stenosis over 36 months. RESULTS One hundred ninety-seven carotid arteries were preliminarily examined. Predilation was performed in 87.4% of cases with a mean balloon diameter of 5.1 ± 0.7 mm and a mean stent diameter was 8.8 ± 1.1 mm. The mean calcium volume percent was 11.9 ± 12.4% and the mean percent residual stenosis was 16.1 ± 15.6%. Univariate logistic regression demonstrated a statistically significant difference between calcium volume percent and percent residual stenosis (odds ratio [OR], 1.324; 95% confidence interval [CI], 1.005-1.746; P = .046). Stratified by quartile, only the top 25% of calcified plaques (>18.7% calcification) demonstrated a statistically significant association with higher percent residual stenosis (OR, 2.532; 95% CI, 1.049-6.115; P =.039). There was no statistical significance with lesion calcification (OR, 1.298; 95% C,: 0.980-1.718; P = .069). A Kaplan-Meier analysis demonstrated a statistically significant increase in the rate of in-stent stenosis during a 36-month follow-up for lesions containing >8.2% calcium volume (P = .0069). CONCLUSIONS A calcium volume percent of >18.7% was associated with a higher percent residual stenosis, and a calcium volume percent of >8.2% was associated with higher in-stent stenosis at 36 months. There was one clinically diagnosed stroke during the follow-up period, demonstrating the overall safety of the procedure.

Abstract
OBJECTIVE The literature suggests that heparin reversal with protamine in transcarotid arterial revascularization (TCAR) decreases postoperative bleeding complications without an increase in stroke or death. However, the dosing of protamine in TCAR has not yet been evaluated. We aimed to evaluate our experience with intraoperative heparin reversal with protamine. METHODS This was a single-center, retrospective, observational study that evaluated the heparin and protamine doses used during TCAR. All adult patients who underwent TCAR between 9/1/2019 and 4/2/2021 were included. Demographic data was obtained from the Vascular Quality Initiative and protamine/heparin doses were obtained from a chart review. Multivariate logistic regression models were used to assess the association between the protamine/heparin dose ratio and other variables. RESULTS Sixty-two patients were included. The average protamine/heparin dose ratio used was 0.96 ± 0.12 mg/U; seven had a ratio less than 0.8 mg/U, and one was greater than 1.2 mg/U. Two patients experienced bleeding complications, which were managed non-operatively. No patient with a protamine/heparin ratio greater than 0.8 mg/U had postoperative bleeding. Postoperative bradycardia was observed in 32.3% of patients and hypotension in 35%, with 19% requiring vasopressors. No relationship was identified between the protamine/heparin ratio and bleeding, bradycardia, or hypotension. No 30-day myocardial infarction, stroke or death occurred. CONCLUSIONS We identified a near 1:1 ratio of a protamine/heparin dosing regimen for the reversal of heparin during TCAR, with postoperative bleeding complications similar to those reported in the literature. However, patients who received a lower protamine/heparin ratio did not experience bleeding complications. In the era of protamine shortages, a future larger-scale study is needed to evaluate the impact of a lower protamine dose on postoperative complications.

Abstract
OBJECTIVE Patients can be considered at high risk for carotid endarterectomy (CEA) because of either anatomic or physiologic factors and will often undergo transcarotid artery revascularization (TCAR). Patients with physiologic criteria will be considered to have a higher overall surgical risk because of more significant comorbidities. Our aim was to study the incidence of stroke, myocardial infarction (MI), death, and combined end points for patients who had undergone TCAR stratified by the risk factors (anatomic vs physiologic). METHODS An analysis of prospectively collected data from the ROADSTER (pivotal; safety and efficacy study for reverse flow used during carotid artery stenting procedure), ROADSTER 2 (Food and Drug Administration indicated postmarket trial; postapproval study of transcarotid artery revascularization in patients with significant carotid artery disease), and ROADSTER extended access TCAR trials was performed. All 851 patients were considered to be at high risk for CEA and were included and stratified using high-risk anatomic criteria (ie, contralateral occlusion, tandem stenosis, high cervical artery stenosis, restenosis after previous endarterectomy, bilateral carotid stenting, hostile neck anatomy with previous neck irradiation, neck dissection, cervical spine immobility) or high-risk physiologic criteria (ie, age >75 years, multivessel coronary artery disease, history of angina, congestive heart failure New York Heart Association class III/IV, left ventricular ejection fraction <30%, recent MI, severe chronic obstructive pulmonary disease, permanent contralateral cranial nerve injury, chronic renal insufficiency). For trial inclusion, asymptomatic patients were required to have had ≥80% carotid stenosis and symptomatic patients to have had ≥50% stenosis. The primary outcome measures were stroke, death, and MI at 30 days. The data were statistically analyzed using the χ2 test, as appropriate. RESULTS A total of 851 high surgical risk patients were categorized into two groups: those with anatomic-only risk factors (n = 372) or at least one physiologic risk factor present (n = 479). Of the 851 patients, 74.5% of those in the anatomic subset were asymptomatic, and 76.6% in the physiologic subset were asymptomatic. General anesthesia was used similarly in both groups (67.7% anatomic vs 68.1% physiologic). MI had occurred in eight patients in the physiologic group (1.7%), all of whom had been asymptomatic and in none of the anatomic patients (P = .01). The combined stroke, death, and MI rate was 2.1% in the anatomic cohort and 4.2% in the physiologic cohort (P = .10). Stratification of each group into asymptomatic and symptomatic patients did not yield any further differences. CONCLUSIONS The patients who had undergone TCAR in the present prospective, neurologically adjudicated trial because of high-risk physiologic factors had had a higher rate of MI compared with the patients who had qualified for TCAR using anatomic criteria only. These patients had experienced comparable rates of combined stroke, death, and MI rates. The anatomic patients represented a healthier and younger subset of patients, with notably low overall event rates.

Hemodynamic Instability Predicts In-Hospital and One-Year Mortality After TransCarotid Artery Revascularization and TransFemoral Carotid Stenting. J Vasc Surg 2023:S0741-5214(23)00548-7. [PMID: 37019157 DOI: 10.1016/j.jvs.2023.03.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 03/06/2023] [Accepted: 03/07/2023] [Indexed: 04/05/2023]
Abstract
OBJECTIVES Blood pressure fluctuations are a common hemodynamic alteration following carotid artery stenting either with transfemoral (TFCAS) or transcarotid (TCAR) approach and are thought to be related to alteration in baroreceptor function due to angioplasty and stent expansion. These fluctuations are particularly worrisome in the high-risk patient population referred for CAS. This study aims to evaluate the outcomes of patients who required the administration of intravenous blood pressure medication (IVBPmed) for hypotension or hypertension after CAS. METHODS All patients undergoing carotid revascularization in the Vascular Quality Initiative (VQI) database between 2016-2021 were included. we compared outcomes of patients who required postoperative IVBPmed to treat hyper- or hypotension with normotensive patients. In-hospital outcomes were compared using multivariable logistic regression. One-year outcomes were assessed using Kaplan-Meier survival and multivariable Cox proportional hazard regression analyses. RESULTS We identified 38,510 patients undergoing CAS (57.7% TCAR and 42.3% TFCAS), of which, 30% received IVBPmed for treatment of either postoperative hypertension (12.6%) or hypotension (16.4%). In multivariable analysis, postoperative hypotension was associated with a higher risk of stroke, death, or MI (OR: 3.1, 95%CI (2.6-3.6), P<.001), stroke or death (OR: 2.9, 95%CI (2.4-3.5), P<.001), stroke (OR: 2.6, 95%CI (2.1-3.2), P<.001), death (OR: 3.5, 95%CI (2.6-4.8), P<.001), MI (OR: 4.7, 95%CI (3.3-6.7), P<.001), and bleeding (OR: 1.96, 95%CI (1.4-2.7), P<.001) compared to normotensive patients. Postoperative hypertension was associated with a higher risk of stroke, death, or MI (3.6, 95%CI (3-4.4), P<.001), stroke or death (OR: 3.3, 95%CI (2.7-4.1), P<.001), stroke (OR: 3.7, 95%CI (3-4.7), P<.001), death (OR: 2.7, 95%CI (1.9-3.9), P<.001), MI (OR: 5.7, 95%CI (3.9-8.3), P<.001), and bleeding (OR: 1.9, 95%CI (1.4-2.7), P<.001) compared to normotensive patients. CONCLUSIONS Postoperative hypertension or hypotension requiring IVBPmed after CAS is associated with an increased risk of in-hospital stroke, death, MI, and bleeding. Postoperative hypertension is associated with worse survival at one year. This study indicates that the need for IVBPmed after CAS is not benign, therefore, these patients necessitate aggressive perioperative medical management and safe techniques to avoid hypo and hypertension. Close follow-up and continue medical management is needed to maximize these patients' survival.

Abstract
BACKGROUND Transcarotid artery revascularization (TCAR) has been proposed as a alternative to carotid endarterectomy (CEA) and transfemoral carotid artery stenting in high-risk patients. Recently Centers for Medicare and Medicaid Services expanded coverage for TCAR to include standard surgical risk patients within the Society of Vascular Surgery Vascular Quality Initiative TCAR Surveillance Project. Few single centers compared the clinical outcome of TCAR with CEA. This study compares 30-day perioperative clinical outcomes between TCAR and CEA. STUDY DESIGN This is retrospective analysis of prospectively collected data from the TCAR Surveillance Project of TCAR patients enrolled in our institution and compared with CEAs done in the same time/with the same providers. The primary outcome was stroke and/or death. Secondary outcomes included stroke, death, MI, cranial nerve injury, bleeding, and others. Propensity matching was done to analyze outcomes. RESULTS The study analyzed 501 patients (347 CEA, 154 TCAR). There were no significant differences in symptomatic status (43% for CEA vs 38% for TCAR, p = 0.303). TCAR had more patients with hypertension (p = 0.04), coronary artery disease (p = 0.028), and congestive heart failure (p = 0.039). The 30-day perioperative complication rates for CEA vs TCAR were as follows: stroke 1% vs 3% (p = 0.142), stroke/death 1% vs 3% (p = 0.185), MI 0.6% vs 0.7% (p = 1), death 0.6% vs 0% (p = 1), stroke/death/MI 2% vs 4% (p = 0.233), cranial nerve injury 4% vs 2% (p = 0.412), and major hematoma (requiring reintervention) 2% vs 3% (p = 1). After matching 154 CEA patients and 154 TCAR, 30-day perioperative complication rates were as follows: stroke 2% vs 3% (p = 0.723), stroke/death 3% vs 3% (p = 1), death 1.3% vs 0% (p = 0.498), MI 0.7% vs 0.7% (p = 1), and stroke/death/MI 3% vs 4% (p = 0.759). CONCLUSIONS This study showed that using propensity match analysis, both CEA and TCAR have similar 30-day perioperative outcomes. Further long-term data are needed.

Abstract
BACKGROUNDS Flow reversal is a key component of transcarotid artery revascularization (TCAR). However, the impact of flow reversal duration on neurological outcomes and the duration of flow reversal which optimizes TCAR's outcomes is not known. We evaluated the association of flow reversal time with the intraoperative and postoperative neurological outcomes of TCAR. METHODS We studied all patients undergoing TCAR from September 2016 to October 2021. The exposure of interest was the duration of flow reversal. Multivariable logistic and fractional polynomial models were used to study the impact of flow reversal duration on in-hospital stroke, intraoperative neurological change/intolerance and stroke/death following TCAR and to identify the flow reversal time above which significant perioperative neurological events occur. RESULTS The study included 19,462 patients with mean age of 73.4 years who were mostly Caucasian (91%) and male (63%). The mean flow reversal time was 10.7 minutes, and the overall stroke rate was 1.4%. The odds of intraoperative neurological change increased by 3.6% per minute increase in flow reversal time (odds ratio (OR), 1.04; 95%, 1.01-1.06; P < 0.002). Flow reversal duration >10 minutes was associated with 78% increased odds of neurological changes compared to flow reversal duration <10 minutes. There was no significant association between flow reversal duration and stroke, and stroke/death in the first 5 minutes after initiation of flow reversal. The odds of stroke increased by 2.7% per minute increase in flow reversal time >5 minutes (OR, 1.03; 95%, 1.01-1.04; P < 0.001), with flow reversal duration >10 minutes associated with 38% increased odds of stroke compared to flow reversal duration ≤10 minutes (OR, 1.37, 95% confidence interval (CI), 1.09-1.73, P = 0.006). The odds of stroke/death increased by 2.5% per minute increase in flow reversal time >5 minutes (OR, 1.03; 95%, 1.01-1.04; P < 0.001). Flow reversal duration >10 minutes was associated with 25% increased odds of stroke/death compared to flow reversal duration <10 minutes (OR, 1.25, 95% CI, 1.01-1.53, P = 0.038). Symptomatic status did not modify outcomes. CONCLUSIONS Our findings suggest that outcomes following TCAR are optimal if the duration of flow reversal is minimized. A clinical cutoff time of 10 minutes is suggested by this study and recommended as a guide. Further studies targeted at the flow reversal component of TCAR are needed to solidify the evidence regarding the clinical effects of temporarily induced retrograde cerebral blood flow during TCAR.

Abstract
OBJECTIVE Hospital resource use is under constant review, and the extent and intensity of postoperative care requirements for vascular surgical procedures is particularly relevant in the setting of the coronavirus disease 2019 pandemic and its impact on staffed intensive care unit (ICU) beds. We sought to evaluate the feasibility of regional anesthesia (RA) and low-intensity postoperative care for patients undergoing transcarotid artery revascularization (TCAR) at our institution. METHODS All patients undergoing TCAR at a single institution from 2018 to 2020 were reviewed. Perioperative management (anticoagulation and antiplatelet therapy, hemodynamic monitoring, neurovascular examination, nursing instructions) was standardized by use of an institutional protocol. Anesthetic modality was at the surgeon's preference. Patients were transferred to a postanesthesia care unit for 2 hours followed by the step-down unit, to a postanesthesia care unit for 4 hours followed by the floor, or alternatively transferred to the ICU. Intravenous (IV) blood pressure medications could be administered at all environments except the floor. Recovery location and length of stay were recorded. RESULTS A total of 83 patients underwent TCAR during the study period. The mean age 72 ± 9 years and 59% were male. Thirty-six percent were symptomatic. RA was used for 84% with none converted to general anesthesia (GA) intraoperatively. Postoperatively, 7 of the 83 patients (8%) included in this study were monitored in an ICU overnight (decided perioperatively), mostly for patients with prior neurological symptoms, but in 1 case for postoperative neurological event and in another owing to pulseless electrical activity arrest. Six patients required IV antihypertensives and eight required IV vasoactive support postoperatively. The mean length of ICU stay was 3.7 ± 5.1 days. The mean length of hospital stay for all patients was 2.4 ± 3.3 days. The length of stay for patients undergoing TCAR with GA was higher than those undergoing TCAR with RA (4.2 ± 4.9 days vs 1.4 ± 1.2 days, respectively; P = .066). The incidence of stroke, death, and myocardial infarction was 2.4%. There was one postoperative stroke considered to be a recrudescence of prior stroke, and one respiratory arrest fatality in a frail patient with neck hematoma both of whom were treated under GA. CONCLUSIONS Using perioperative care protocols, TCAR can safely be performed while avoiding both GA and an ICU stay in most patients.

Abstract
Objective Transcarotid artery revascularization (TCAR) is thought to be a promising technique and instrument for treating carotid stenosis with favorable outcomes. Since there remain several differences in anatomic characteristics among races, this study was conducted to investigate the anatomic eligibility of TCAR in Chinese patients who underwent carotid revascularization. Methods A retrospective review of patients with carotid stenosis from 2019 to 2021 was conducted. The anatomic eligibility of TCAR was based on the instruction of the ENROUTE Transcarotid Neuroprotection System. The carotid artery characteristics and configuration of the circle of Willis (CoW) were evaluated by CT angiography. The demographic and clinical characteristics and procedure-related complications were recorded. Logistic regression was used to analyze the independent factors for TCAR eligibility. Results Of 289 consecutive patients [222 for carotid endarterectomy (CEA) and 67 for transfemoral carotid artery stenting (TF-CAS)] identified, a total of 215 patients (74.4%) met TCAR anatomic eligibility. Specifically, 83.7% had mild common carotid artery (CCA) puncture site plaque, 95.2% had 4-9 mm internal carotid artery diameters, 95.8% had >6 mm CCA diameter, and 98.3% had >5 cm clavicle to carotid bifurcation distance. Those who were female (OR, 5.967; 95% CI: 2.545-13.987; P < 0.001), were of an older age (OR, 1.226; 95% CI: 1.157-1.299; P < 0.001), and higher body mass index (OR, 1.462; 95% CI: 1.260-1.697; P < 0.001) were prone to be associated with TCAR ineligibility. In addition, 71 patients with TCAR eligibility (33.0%) were found to combine with incomplete CoW. A high risk for CEA was found in 29 patients (17.3%) with TCAR eligibility, and a high risk for TF-CAS was noted in nine patients (19.1%) with TCAR eligibility. Overall, cranial nerve injury (CNI) was found in 22 patients after CEA, while 19 of them (11.3%) met TCAR eligibility. Conclusion A significant proportion of Chinese patients meet the anatomic criteria of TCAR, making TCAR a feasible treatment option in China. Anatomic and some demographic factors play key roles in TCAR eligibility. Further analysis indicates a potential reduction of procedure-related complications in patients with high-risk carotid stenosis under the TCAR procedure.

Abstract
OBJECTIVE Carotid artery stenting (CAS) is frequently used for patients at high risk for carotid endarterectomy. However, there are limited data comparing transradial or transbrachial (tr/tbCAS) access with more established CAS approaches. Therefore, we examined the effect of a tr/tbCAS approach versus a transfemoral (tfCAS) or transcarotid (TCAR) approach on outcomes after CAS. METHODS We identified all patients undergoing CAS in the Vascular Quality Initiative registry from January 2016 to December 2021. We compared outcomes across 1:3 propensity score-matched cohorts of patients who underwent tr/tbCAS versus tfCAS or tr/tbCAS versus TCAR. As a secondary analysis, we assessed outcomes stratified by carotid symptom status. Our primary outcome was a composite end point of in-hospital stroke/death. RESULTS Among 40,835 CAS patients, 962 (2.4%) underwent tr/tbCAS, 18,840 (46%) underwent tfCAS, and 21,033 (52%) underwent TCAR. Among matched patients who underwent tr/tbCAS versus tfCAS, there was no significant difference in the risk of stroke/death (4.1% vs 2.9%; relative risk [RR] 1.4; 95% confidence interval [CI], 0.95-2.1), but tr/tbCAS was associated with a higher risk of death (2.4% vs 1.3%; RR, 1.8; 95% CI, 1.1-3.1). In the symptomatic subgroup, tr/tbCAS was associated with a higher risk of stroke/death (6.1% vs 3.9%; RR, 1.6; 95% CI, 1.0-2.4) and death (3.6% vs 1.7%; RR, 2.1; 95% CI, 1.2-3.7), but there were no differences in asymptomatic patients. After adjustment for mRS in patients with preoperative stroke, there were no significant differences in stroke/death (RR, 1.1; 95% CI, 0.66-1.9) or death (RR, 1.6; 95% CI, 0.81-3.3) between groups. In matched patients who underwent tr/tbCAS versus TCAR, tr/tbCAS was associated with a higher risk of stroke/death (4.2% vs 2.3%; RR, 1.8; 95% CI, 1.2-2.7) and death (2.4% vs 0.5%; RR, 4.8; 95% CI, 2.4-9.5). In the symptomatic subgroup, tr/tbCAS remained associated with a higher risk of stroke/death (6.2% vs 2.4%; RR, 2.6; 95% CI, 1.6-4.2) and death (3.7% vs 0.7%; RR, 5.6; 95% CI, 2.6-12), but there were no differences in asymptomatic patients. After adjustment for Modified Rankin Scale in patients with preoperative stroke, there were no significant differences in stroke/death (RR, 1.4; 95% CI, 0.79-2.6) or death (RR, 2.3; 95% CI, 0.95-5.7) between groups. CONCLUSIONS Compared with tfCAS or TCAR, tr/tbCAS was associated with a higher risk of in-hospital stroke/death in symptomatic patients, which was driven primarily by a higher risk of death. These inferior outcomes were partly attributable to more severe preoperative neurologic disability in tr/tbCAS patients. In contrast, there were no differences in outcomes in asymptomatic patients. Overall, our findings highlight the importance of guideline-directed patient selection in tr/tbCAS.

Outcomes after transcarotid artery revascularization stratified by preprocedural symptom status. J Vasc Surg 2022; 76:1307-1315.e1. [PMID: 35798281 PMCID: PMC9613587 DOI: 10.1016/j.jvs.2022.05.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 04/14/2022] [Accepted: 05/09/2022] [Indexed: 10/31/2022]
Abstract
OBJECTIVE Previous studies on carotid endarterectomy and transfemoral carotid artery stenting demonstrated that perioperative outcomes differed according to preoperative neurologic injury severity, but this has not been assessed in transcarotid artery revascularization (TCAR). In this study, we examined contemporary perioperative outcomes in patients who underwent TCAR stratified by specific preprocedural symptom status. METHODS Patients who underwent TCAR between 2016 and 2021 in the Vascular Quality Initiative were included. We stratified patients into the following groups based on preprocedural symptoms: asymptomatic, recent (symptoms occurring <180 days before TCAR) ocular transient ischemic attack (TIA), recent hemispheric TIA, recent stroke, or formerly symptomatic (symptoms occurring >180 days before TCAR). First, we used trend tests to assess outcomes in asymptomatic patients versus those with an increasing severity of recent neurologic injury (recent ocular TIA vs recent hemispheric TIA vs recent stroke). Then, we compared outcomes between asymptomatic and formerly symptomatic patients. Our primary outcome was in-hospital stroke/death rates. Multivariable logistic regression was used to adjust for demographics and comorbidities across groups. RESULTS We identified 18,477 patients undergoing TCAR, of whom 62.0% were asymptomatic, 3.2% had a recent ocular TIA, 7.6a % had recent hemispheric TIA, 18.0% had a recent stroke, and 9.2% were formerly symptomatic. In patients with recent symptoms, we observed higher rates of stroke/death with increasing neurologic injury severity: asymptomatic 1.1% versus recent ocular TIA 0.8% versus recent hemispheric TIA 2.1% versus recent stroke 3.1% (Ptrend < .01). In formerly symptomatic patients, the rate of stroke/death was higher compared with asymptomatic patients, but this difference was not statistically significant (1.7% vs 1.1%; P = .06). After risk adjustment, compared with asymptomatic patients, there was a higher odds of stroke/death in patients with a recent stroke (odds ratio [OR], 2.8; 95% confidence interval [CI], 2.1-3.7; P < .01), a recent hemispheric TIA (OR, 2.0; 95% CI, 1.3-3.0; P < .01), and former symptoms (OR, 1.6; 95% CI, 1.1-2.5; P = .02), but there was no difference in stroke/death rates in patients with a recent ocular TIA (OR, 0.9; 95% CI, 0.4-2.2; P = .78). CONCLUSIONS After TCAR, compared with asymptomatic status, a recent stroke and a recent hemispheric TIA were associated with higher stroke/death rates, whereas a recent ocular TIA was associated with similar stroke/death rates. In addition, a formerly symptomatic status was associated with higher stroke/death rates compared with an asymptomatic status. Overall, our findings suggest that classifying patients undergoing TCAR as symptomatic versus asymptomatic may be an oversimplification and that patients' specific preoperative neurologic symptoms should instead be used in risk assessment and outcome reporting for TCAR.

Abstract
BACKGROUND Revascularization practices with respect to asymptomatic carotid stenosis (ACAS) are known to vary widely among proceduralists. In addition, regional market competition has been previously shown to drive more aggressive practices in a number of surgical procedures. The aim of our study was to examine the association of regional market competition with revascularization thresholds for ACAS. METHODS All patients undergoing carotid revascularization in the Vascular Quality Initiative carotid endarterectomy and stenting databases (2016-2020) were included. High-grade carotid stenosis was defined as ≥80%. We calculated the Herfindahl-Hirschman Index (HHI; a measure of physician market competition) for each U.S region as defined by the U.S Department of Health and Human Services. Logistic regression was used to examine the association of degree of carotid stenosis at revascularization with HHI stratified by symptomatology, adjusting for age, sex, race, insurance, and revascularization modality. RESULTS Of 92,243 carotid interventions, 57,094 (61.9%) were performed for ACAS and 35,149 (38.1%) were performed for symptomatic carotid stenosis (SCAS). ACAS patients undergoing revascularization for moderate-grade stenosis were significantly less likely to be aspirin (85.6% vs. 86.3%), clopidogrel (41.3% vs. 45.1%), dual anti-platelet therapy (35.9% vs. 39.2%) and systemic anticoagulants (10.9 vs. 11.7%) compared to high-grade stenosis (all P < 0.05). Multivariable analysis demonstrated that decreased local market competition was independently associated with a lower odds of revascularization for moderate versus high-grade ACAS (odds ratio OR: 0.99 per 10 point increase in HHI, 95% confidence interval CI: 0.98-0.99). There was no association of local market competition with degree of carotid stenosis at time of revascularization among patients with SCAS (OR: 1.00 per 10 point increase in HHI, 95% CI: 0.99-1.00). Among ACAS patients, patients with moderate-grade stenosis had a higher odds ratio of in-hospital stroke or death compared to patients with high-grade stenosis (OR: 1.22, 95% CI 1.03-1.45). This association was not redemonstrated in the SCAS group (OR: 0.92, 95% CI: 0.80-1.06). CONCLUSIONS Increased local market competition is associated with a lower threshold for revascularization of ACAS. There is no association between regional market competition and revascularization threshold for SCAS. These findings, combined with the significantly increased risk of perioperative stroke/death among moderate-grade ACAS patients, suggest that competition among proceduralists may result in a higher tolerance for increased operative risk in patients who might otherwise be reasonable candidates for surveillance.

Abstract
Background Transcarotid artery revascularization (TCAR) was approved by the Food and Drug Administration in 2015 for patients with carotid artery stenosis. However, no randomized trial to evaluate TCAR has been performed to date, and previous reports have important limitations. Accordingly, we measured stroke or death after TCAR compared with carotid endarterectomy (CEA) and transfemoral carotid artery stenting (TF-CAS). Methods and Results We used the Vascular Quality Initiative registry to study patients who underwent TCAR, CEA, or TF-CAS from September 2016 to June 2021. Our primary outcomes were perioperative and 1-year stroke or death. We used logistic regression for risk adjustment for perioperative outcomes and Cox regression for risk adjustment for 1-year outcomes. We used a 2-stage residual inclusion instrumental variable (IV) method to adjust for selection bias and other unmeasured confounding. Our instrument was a center's preference to perform TCAR versus CEA or TF-CAS. We performed a subgroup analysis stratified by presenting neurologic symptoms. We studied 21 234 patients who underwent TCAR, 82 737 who underwent CEA, and 14 595 who underwent TF-CAS across 662 centers. The perioperative rate of stroke or death was 2.0% for TCAR, 1.7% for CEA, and 3.7% for TF-CAS (P<0.001). Compared with TCAR, the IV-adjusted odds ratio of perioperative stroke or death for CEA was 0.74 (95% CI, 0.55-0.99) and for TF-CAS was 1.66 (95% CI, 0.99-2.79). Results were similar among both symptomatic and asymptomatic patients. The 1-year rate of stroke or death was 6.4% for TCAR, 5.2% for CEA, and 9.7% for TF-CAS (P<0.001). Compared with TCAR, the IV-adjusted hazard ratio of 1 year stroke or death for CEA was 0.97 (95% CI, 0.80-1.17), and for TF-CAS was 1.45 (95% CI, 1.04-2.02). IV analysis further demonstrated that symptomatic patients with carotid stenosis had the lowest 1-year likelihood of stroke or death with TCAR (compared with TCAR, symptomatic IV-adjusted hazard ratio for CEA: 1.30 [95% CI, 1.04-1.64], and TF-CAS: 1.86 [95% CI, 1.27-2.71]). Conclusions Perioperative stroke or death was greater following TCAR when compared with CEA. However, at 1 year there was no statistically significant difference in stroke or death between the 2 procedures. TCAR performed favorably compared with TF-CAS at both time points. Although CEA remains the gold standard procedure for patients with carotid stenosis, TCAR appears to be a safe alternative to CEA and TF-CAS when used selectively and may be useful when treating symptomatic patients.

Abstract
Introduction Transcarotid artery revascularization (TCAR) is a hybrid open and endovascular technique to treat carotid stenosis. The purpose of this study is to present a large cohort of patients who underwent TCAR at 2 high-volume TCAR health systems. Methods This study was a retrospective chart review of all instances of TCAR within the Memorial Hermann Health System and Indiana University Health, from December 2015-January 2022, using the ENROUTE Neuroprotection Device (Silk Road Medical, Sunnyvale, CA). We report patient demographics, intraoperative metrics, 30-day results and long-term results. Results In all, 750 patients underwent TCAR in the designated time period. Average patient age was 73 years, with 68% being male. Overall, 53.9% of patients had coronary artery disease, 45.4% had diabetes, and 36.9% were symptomatic. Technical success was achieved in 98.8% of patients with conversion to open endarterectomy in 1.1%. Average reverse flow time was 9.1 minutes with length of stay greater than 1 day 38%. Ipsilateral stroke rate within 30 days was 2.3% and long-term cumulative stroke rate was 3.0%. Death within 30 days occurred in 1.2% of patients and in 5.9% over long-term follow up. In all, 1% of patients required reintervention. Conclusions TCAR is a safe and effective treatment modality for carotid artery stenotic disease. Its outcomes are similar to historical results associated with carotid endarterectomy, long considered the gold standard.

Abstract
IMPORTANCE A transcarotid artery revascularization (TCAR) device was approved by the US Food and Drug Administration in 2015 for carotid revascularization in patients at high risk for stroke, cranial nerve injury, or major cardiac event. It is unclear how the introduction of TCAR has changed the use of carotid endarterectomy (CEA) and transfemoral carotid artery stenting (TFCAS). OBJECTIVE To quantify the temporal changes in the operative approach to carotid revascularization (CEA vs TFCAS vs TCAR), and to identify patient and disease characteristics commonly associated with each approach. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study obtained data from the Vascular Quality Initiative database from January 1, 2015, to December 31, 2019. Patients with carotid artery stenosis who underwent CEA, TFCAS, or TCAR were included. Data were analyzed from January to April 2022. EXPOSURES Month and year of surgery as well as patient risk status. MAIN OUTCOMES AND MEASURES Number and proportion of carotid revascularization procedures by operative approach. RESULTS A total of 108 676 patients (mean [SD] age 56.6 [12.5] years; 66 684 men [61.4%]) were included in the analysis. The most common operative approach overall was CEA (n = 81 508 [75.0%]), followed by TFCAS (n = 15 578 [14.3%]) and TCAR (n = 11 590 [10.7%]). The number of procedures increased over the study period (16 754 in 2015 vs 27 269 in 2019; P < .001). In 2015, CEA was used in 84.9% of all cases, followed by TFCAS (14.4%) and TCAR (0.8%). In 2019, CEA was used in 64.8% of cases, followed by TCAR (21.9%) and TFCAS (13.3%). The proportional use of CEA decreased by 5.0% (95% CI, -7.4% to -2.6%) per year, and TCAR use increased by 5.3% (95% CI, 2.3%-8.3%) per year. Among patients at high risk, the change was greater: CEA use decreased by 7.8% (95% CI, -11.9% to -3.8%) per year, TFCAS decreased by 4.8% (95% CI, -9.5% to -0.14%) per year, and TCAR increased by 12.6% (95% CI, 7.1%-18.1%) per year. Multinomial logistic regression showed that patient risk status was the most important characteristic associated with TCAR compared with CEA (relative risk ratio, 36.10; 95% CI, 29.24-44.66; P < .001) and TFCAS (relative risk ratio, 14.10; 95% CI, 11.86-16.66; P < .001). Linear regression revealed no association between year of surgery and in-hospital myocardial infarction, stroke, or mortality. CONCLUSIONS AND RELEVANCE Results of this study indicate that TCAR has become the dominant carotid revascularization approach, surpassing TFCAS and CEA in patients at high risk for stroke, cranial nerve injury, or cardiovascular events. Patient high-risk status was the main characteristic associated with a stenting approach, highlighting the perceived importance of carotid stenting therapies in this patient population.

Abstract
Transcarotid artery revascularization (TCAR) is a novel carotid stenting method that avoids the manipulation of the aortic arch and uses a flow-reversal neuroprotection system that effectively reduces the risk of embolic events during carotid intervention. Studies have shown a lower risk of stroke or death compared with the transfemoral carotid stenting approach, and an equivalent risk of stroke or death compared with traditional carotid endarterectomy. TCAR has added benefits of lower risk of myocardial infarction, cranial nerve injuries, and shorter operative times compared with endarterectomy. TCAR has become widely adopted by vascular surgeons in the United States for the treatment of patients with high-risk medical comorbidities and those with challenging surgical anatomy.

Abstract
OBJECTIVE Age ≥80 years is known to be an independent risk factor for periprocedural stroke after transfemoral carotid artery stenting (TF-CAS) but not after carotid endarterectomy (CEA). The objective of the present study was to compare the perioperative outcomes for CEA, TF-CAS, and transcarotid artery revascularization (TCAR) among octogenarian patients (aged ≥80 years) overall and stratified by symptom status and degree of stenosis. METHODS All patients aged ≥80 years with 50% to 99% carotid artery stenosis who had undergone CEA, TF-CAS, or TCAR in the Vascular Quality Initiative (2005-2020) were included. We compared the perioperative (30-day) incidence of ipsilateral stroke or death for CEA vs TF-CAS vs TCAR using analysis of variance and multivariable logistic regression models. The results were confirmed in a sensitivity analysis stratified by symptom status and degree of stenosis. RESULTS Overall, 28,571 carotid revascularization procedures were performed in patients aged ≥80 years: CEA, n = 20,912 (73.2%), TF-CAS, n = 3628 (12.7%), and TCAR, n = 4031 (14.1%). The median age was 83 years (interquartile range, 81.0-86.0 years); 49.8% of the patients were symptomatic (51.9% CEA, 46.2% TF-CAS, 42.4% TCAR); and 60.7% had high-grade stenosis (59.0% CEA, 65.2% TF-CAS, 65.4% TCAR). Perioperative stroke/death occurred most frequently following TF-CAS (6.6%), followed by TCAR (3.1%) and CEA (2.5%; P < .001). After adjusting for baseline differences between groups, the odds ratio (OR) for stroke/death was greater for TF-CAS vs CEA (adjusted OR [aOR], 3.35; 95% confidence interval [CI], 2.65-4.23), followed by TCAR vs CEA (aOR 1.49, 95% CI 1.18-1.87). The risk of perioperative stroke/death remained significantly greater for TF-CAS compared with CEA regardless of symptom status and degree of stenosis (P < .05 for all). In contrast, the risk of stroke/death was higher for TCAR vs CEA for asymptomatic patients (aOR, 2.04; 95% CI, 1.41-2.94) and those with high-grade stenosis (aOR, 1.49; 95% CI, 1.11-2.05) but similar for patients with symptomatic and moderate-grade disease (P > .05 for both). The risk of myocardial infarction was lower with TCAR (aOR, 0.59; 95% CI, 0.40-0.87) and TF-CAS (aOR, 0.56; 95% CI, 0.40-0.87) compared with CEA overall. CONCLUSIONS Overall, TCAR and CEA can be safely offered to older adults, in particular, symptomatic patients and those with moderate-grade stenosis. TF-CAS should be avoided in older patients when possible.

Abstract
OBJECTIVES Approximately 20-30% of ischemic strokes are caused by internal carotid artery stenosis. Stroke is the leading cause of disability and the second leading cause of death in the United States. Second generation Trans Carotid Arterial Revascularization (TCAR) stenting, using the ENROUTE flow reversal technology to prevent embolic stroke during the stenting process, has demonstrated stroke and death outcomes equivalent to CEA with reduced cranial nerve injury. However, at present, it is not known whether imaging characteristics obtained pre-operatively can predict outcomes of TCAR procedures. METHODS This retrospective cohort study included patients who underwent TCAR with flow reversal at 3 hospitals within a single hospital network who had CT angiography, MRI angiography or pre-operative diagnostic angiogram to determine whether carotid and lesion characteristics could predict patients who experienced Major Adverse Critical Events (MACE) versus those who did not. MACE was defined as myocardial infarction at 30 days, restenosis/persistent stenosis (peak systolic velocity within the stent >230cm/sec by post-operative ultrasound), stroke within any time of follow up or death within 1 year of TCAR. Student's t-tests and chi-squared tests were used to compare imaging characteristics, such as presence of pinpoint stenosis, calcification within the common carotid artery (CCA) at the take-off from the aorta, and plaque length in millimeters. Binomial logistic regression was used to examine the likelihood that imaging characteristics were associated with MACE. RESULTS Of 220 patients who underwent TCAR in our network, 7 were excluded because flow reversal was not used or appropriate imaging had not been performed prior to TCAR. Of the 213 patients that were included in analysis, the median length of follow up was 10.8 months (IQR: 3.4-33.1 months). Twelve percent (26/213) experienced a MACE, and a model based on imaging characteristics was statistically significant in predicting MACE with 68% accuracy (P=0.005). The presence of pinpoint stenosis was highly predictive of MACE (HR: 3.34, CI: 1.2 to 9.3, P=0.021). A shorter clavicle to carotid bifurcation distance was associated with an increased likelihood of experiencing a MACE (P=0.009), but it was weakly predictive (HR 1.03, CI: 1.01 to 1.05). CONCLUSIONS Pre-operative imaging characteristics, such as pinpoint stenosis and clavicle to carotid bifurcation distance, can be used to predict adverse outcomes in TCAR placement.

Abstract
OBJECTIVE Carotid revascularization within 14 days of a neurologic event is recommended by society guidelines. Transcarotid artery revascularization (TCAR) carries the lowest overall stroke rate for any carotid artery stenting technique; however, outcomes of TCAR within 14 days of a neurologic event have not been directly compared to carotid endarterectomy (CEA). METHODS We compared 30-day outcomes of symptomatic patients undergoing TCAR and CEA within 14 days of stroke or transient ischemic attack (TIA) from January 2016 to February 2020 using the Society for Vascular Surgery Vascular Quality Initiative (VQI) carotid artery stenting and CEA databases. Propensity score matching was used to adjust for patient risk factors. The primary outcome was a composite of postoperative ipsilateral stroke, death, and myocardial infarction (MI). RESULTS A total of 1,281 symptomatic patients underwent TCAR and 13,429 patients underwent CEA within 14 days of a neurologic event. After 1:1 propensity matching, 728 matched pairs were included for analysis. The primary composite outcome of stroke, death, or MI was more frequent in the TCAR group (4.7% vs. 2.6%, p= 0.04). This was driven by a higher rate of post-operative ipsilateral stroke in the TCAR group (3.8% vs. 1.8%, p=0.005). There was no difference between TCAR and CEA in terms of death (0.7% vs. 0.8%, p= 0.8) or MI (0.8% vs. 1%, p= 0.7). Although TCAR procedures were shorter (69 minutes IQR 53-85 vs. 120 minutes IQR 93-150, p<0.001) and post procedure length of stay was similar (2 days, p= 0.3) compared to CEA, TCAR patients were more likely to be discharged to a facility other than home (26% vs. 19%, p<0.01). Performing TCAR within 48 hours of a stroke was an independent predictor of post-operative stoke or TIA (OR 5.4 95% CI 1.8-16). This increased risk of post-operative stroke or TIA was not seen when performing TCAR within 48 hours of a TIA. CONCLUSION TCAR within 14 days of a neurologic event results in higher ipsilateral post-operative stroke rates when compared to CEA, especially when performed within 48 hours of a stroke.

Abstract
Stenotic lesions of the supra-aortic vessels have been reported in 2-6% of patients presenting with corresponding symptoms. In the past, these lesions have been treated with open surgical techniques. More recently, endovascular treatment approaches have been proposed for occlusive lesions in the innominate (IA) or common carotid (CCA) arteries. Retrograde stenting of IA and CCA lesions using flow reversal has been described in a retrospective case series; however, a modification of their technique is proposed. Case Presentation: The patient is a 68-year-old male with symptoms of right upper extremity claudication. CT angiogram revealed critical stenosis of the innominate artery and high-grade stenosis of the right subclavian artery. The patient consented to retrograde stenting of the innominate stenosis with neuroprotection using flow reversal or transcarotid revascularization (TCAR) in reverse. Surgical cut-down was performed of the carotid bifurcation, and a U-stitch was placed on the anterior wall of the distal common carotid artery. Flow reversal was achieved by connecting the arterial sheath to the venous sheath. The innominate lesion was crossed, primarily stented with a VBX stent, and post-dilated with a non-compliant balloon. Just prior to crossing the lesion and primary stent placement, the vessel loop around the common carotid and internal carotid arteries were pulled up to ensure neuroprotection while the stent was expanded. This was continued for two minutes before restoring antegrade flow first in the external carotid and then in the internal carotid artery. There were no adverse events. At one month follow-up, the patient reported no right arm claudication symptoms. TCAR for the proximal lesion as described in other case series may not adequately attain flow based neuroprotection. Under that circumstance, the arterial sheath is acting as a conduit to deliver the stent. Risk of embolization to the brain may not be mitigated when the proximal lesion is stented and antegrade flow restored.

Abstract
BACKGROUND Carotid artery stenting, including both transfemoral carotid artery stenting (TFCAS) and transcarotid artery revascularization (TCAR), reimbursement has been limited to high-risk patients by the Centers for Medicare & Medicaid Services (CMS) since 2005. We aimed to assess the association of CMS high-risk status with perioperative outcomes for carotid endarterectomy (CEA), TFCAS, and TCAR. METHODS We performed a retrospective review of all Vascular Quality Initiative (VQI) patients who underwent carotid revascularization between 2015 and 2020. Patients were stratified by whether they met CMS CAS criteria, and univariable and multivariable logistic regression analyses were performed to assess the association of procedure type (CEA, TFCAS, TCAR) with perioperative stroke. RESULTS Of 124,531 individuals who underwent carotid revascularization procedures, 91,687 (73.6%) underwent CEA, 17,247 (13.9%) underwent TFCAS, and 15,597 (12.5%) underwent TCAR. Among patients who met CMS CAS criteria (i.e., high-risk patients), the incidence of perioperative stroke was 2.7% for CEA, 3.4% for TFCAS, and 2.4% for TCAR (p<0.001). Among standard-risk patients, the incidence of perioperative stroke was 1.7% for CEA, 2.7% for TFCAS, and 1.8% for TCAR (p<0.001). After adjusting for baseline demographic and clinical characteristics, the odds of perioperative stroke were lower for TCAR vs. CEA in high-risk patients [adjusted odds ratio (aOR) 0.82 (95% CI 0.68, 0.99)] and similar in standard-risk patients [aOR 1.05 (95% CI 0.84, 1.31)]. In contrast, the adjusted odds of perioperative stroke were higher for TFCAS vs. CEA in high-risk patients [aOR 1.23 (95% CI 1.03, 1.46)] and standard-risk patients [aOR 1.60 (95% CI 1.37, 1.86)]. In both populations, TFCAS and TCAR patients had significantly lower odds of MI than CEA patients (both, p<0.001). CONCLUSIONS The perioperative risks associated with CEA, TFCAS, and TCAR in high-risk patients support the current Centers for Medicare & Medicaid Services (CMS) criteria, while the risks associated with each revascularization approach in standard-risk patients suggest that distinguishing TCAR from TFCAS may be warranted.
