Optimal Catheter Selection for Patients with Acute Stroke with Type III Aortic Arch Based on Magnetic Resonance Angiography Road Mapping of the Para-Aortic Transfemoral Access Route Before Mechanical Thrombectomy. World Neurosurg 2024; 190:e153-e157. [PMID: 39025259 DOI: 10.1016/j.wneu.2024.07.076] [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: 07/06/2024] [Accepted: 07/08/2024] [Indexed: 07/20/2024]
Abstract
BACKGROUND Although mechanical thrombectomy for acute ischemic stroke has a high recanalization rate, procedurally challenging lesions remain in approximately 10% of the cases. Type III aortic arches, due to their anatomical configuration, are a fundamental problem impacting this procedure. This study aimed to determine whether optimal catheter selection for type III aortic arches, using magnetic resonance angiography (MRA)-based road mapping of the para-aortic transfemoral access route, reduces the time required for mechanical thrombectomy. METHODS We retrospectively evaluated 203 consecutive patients who underwent mechanical thrombectomy at multiple centers between April 2018 and July 2022. 23 patients were diagnosed with a type III aortic arch using MRA-based road mapping performed to visualize the para-aortic access route before neuro-interventional procedures. Among the 23 patients with type III aortic arches, 10 received a Simmons-type catheter (initial Simmons group) and 13 received a JB-2-type catheter (initial JB-2 group) as their first inner catheter. The time required for mechanical thrombectomy was compared between the groups. RESULTS Compared with the initial JB-2 group, the initial Simmons group exhibited a significantly shorter "puncture-to-recanalization time" (105 vs. 53 minutes, P = 0.009) and "door-to-recanalization time" (164 vs. 129 minutes, P = 0.032). CONCLUSIONS Optimal catheter selection by identifying the aortic arch before mechanical thrombectomy using MRA-based road mapping effectively reduced the mechanical thrombectomy time. This suggests that even in type III aorta cases, appropriate catheter selection may shorten the mechanical thrombectomy time and improve acute ischemic stroke prognosis.

J Clin Neurosci 2024; 128:110787. [PMID: 39159591 DOI: 10.1016/j.jocn.2024.110787] [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: 03/18/2024] [Revised: 07/17/2024] [Accepted: 08/10/2024] [Indexed: 08/21/2024]
Abstract
OBJECTIVE To investigate the effect of embolic protection device (EPD) use on periprocedural complications in patients with carotid artery stenosis with anatomical variations. METHOD The study retrospectively evaluated 185 patients who consecutively underwent carotid artery stenting between November 2020 and December 2023. Forty-four patients with difficult anatomical structures, anatomical variations in the common carotid artery (CCA) and internal carotid artery (ICA) (tortuosity, kinking, or coiling), and a CCA-ICA angle of >60 degrees were included in the sample. The patients were divided into two groups according to the use of EPD filters during the procedure and compared in terms of periprocedural events. RESULTS Of the 44 patients included in the study, 24 (54.5 %) were male, and the mean age of all patients was 68.7 ± 8.7 years. Comorbidities were present in 93.2 % (n = 41) of the patients. The most common comorbidity was hypertension (n = 32, 72.8 %). The CCA-ICA angle was ≥60 degrees in 45.4 % (n = 20) of all patients. ICA tortuosity was detected in 27.2 % (n = 12) of the patients, ICA kinking in 13.6 % (n = 6), ICA coiling in 6.8 % (n = 3), and CCA tortuosity in 6.8 % (n = 3). Procedure-related periprocedural events developed in 38.6 % (n = 17) of the patients. Postprocedural mortality occurred in two patients, secondary to myocardial infarction in one and COVID-19 pneumonia in the other. There was no significant difference between the filter and non-filter groups in relation to periprocedural events (p = 0.638). Major stroke did not occur in either group. Minor neurological events occurred in 15 % (n = 3/20) of the patients in the filter group and 16.7 % (n = 4/24) of those in the non-filter group. The incidence of vasospasm was statistically higher in patients using filters compared to those without filters (30 % vs. 0 %; P = 0.005, respectively). CONCLUSION Evaluation of vascular anatomy before carotid artery stenting is important to decide on the technical procedure to be applied in the procedure. The use of EPD in unfavorable anatomy does not reduce periprocedural neurological events. Instead, it results in technical difficulties, prolongs the duration of procedure, and leads to arterial vasospasm. Considering the high periprocedural events in this study, carotid endarterectomy may be a better alternative to endovascular treatment in patients with unfavorable carotid artery anatomy.

A thoracic CT imaging parameter predicting access difficulty in acute stroke thrombectomy. Clin Neurol Neurosurg 2024; 244:108453. [PMID: 39038419 DOI: 10.1016/j.clineuro.2024.108453] [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: 03/02/2024] [Revised: 06/27/2024] [Accepted: 07/12/2024] [Indexed: 07/24/2024]
Abstract
PURPOSE The quick establishment of adequate vascular access is essential for the technical success of mechanical thrombectomy (MT). Focusing on shifts in aortic arch geometry and aging-related changes, we propose an imaging parameter for predicting access difficulty using chest CT. METHODS Patients with acute anterior circulation large-vessel occlusion who underwent MT from April 2020 to September 2021 were included in this retrospective multicenter observational study. The distance from the sternum to the ascending aorta (S-AAD) was defined as the surrogate marker of access difficulty. Access was defined as difficult when the time from femoral sheath placement to guiding catheter induction (guiding time: GT) ≥ 30 minutes, and the patients were dichotomized into groups with short GT (sGT: GT < 30 min) and long GT (lGT: GT ≥ 30 min). RESULTS One hundred fifteen patients were included. There were 12 patients (10.4 %) in lGT group. The median (IQR) S-AAD was 11.9 mm (6.3, 18.3 mm) in sGT group and 6.6 mm (4.0, 10.3 mm) in lGT group, and a significant difference in S-AAD was observed (P = 0.026). In multivariate analyses, dyslipidemia and S-AAD < 5 mm were significantly associated with difficult access (OR, 5.938 [95 % CI, 1.468, 24.022], P = 0.012 for dyslipidemia; OR, 5.147 [95 % CI, 1.267, 20.917], P = 0.022 for S-AAD < 5 mm). CONCLUSION S-AAD is a simple and reliable imaging parameter to predict access difficulty. This parameter may be helpful in selecting the appropriate devices and access routes in preinterventional practice.

Hamouda M, Alqrain S, Zarrintan S, Yei K, Barleben A, Malas MB. Transcarotid artery revascularization outperforms transfemoral carotid artery stenting regardless of aortic arch type or degree of atherosclerosis. J Vasc Surg 2024:S0741-5214(24)01680-X. [PMID: 39134214 DOI: 10.1016/j.jvs.2024.07.101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2024] [Revised: 07/31/2024] [Accepted: 07/31/2024] [Indexed: 09/09/2024]
Abstract
OBJECTIVE The Centers for Medicare and Medicaid Services now approve reimbursement for transfemoral carotid artery stenting (TFCAS) in the treatment of standard-risk patients with carotid artery occlusive disease. TFCAS in patients with complex aortic arch anatomy is known to be challenging with worse outcomes. Transcarotid artery revascularization (TCAR) could be a preferable alternative in these patients owing to avoiding the aortic arch and using flow reversal during stent deployment. We aim to compare the outcomes of TCAR vs TFCAS across all aortic arch types and degrees of arch atherosclerosis. METHODS All patients undergoing carotid artery stenting between September 2016 and October 2023 were identified in the Vascular Quality Initiative database. Patients were stratified into four groups: Group A (mild atherosclerosis and type I/II arch), Group B (mild atherosclerosis and type III arch), Group C (moderate/severe atherosclerosis and type I/II arch), and Group D (moderate/severe atherosclerosis and type III arch). The primary outcome was in-hospital composite stroke or death. Analysis of variance and χ2 tests analyzed differences for baseline characteristics. Logistic regression models were adjusted for potential confounders, and backward stepwise selection was implemented to identify significant variables for inclusion in the final models. Kaplan-Meier survival estimates, log rank test, and multivariable Cox regression models analyzed hazard ratios for 1-year mortality. RESULTS A total of 20,114 patients were included (Group A: 12,980 [64.53%]; Group B: 1175 [5.84%]; Group C: 5124 [25.47%]; and Group D: 835 [4.15%]). TCAR was more commonly performed across the four groups (72.21%, 67.06%, 74.94%, and 69.22%; P < .001). Compared with patients with mild arch atherosclerosis, patients with advanced arch atherosclerosis in Group C and Group D were more likely to be female, hypertensive, smokers, and have chronic kidney disease. Patients with type III arch in Group B and Group D were more likely to present with stroke preoperatively. On multivariable analysis, TCAR had less than one-half the risk of stroke/death and 1-year mortality compared with TFCAS in the patients with the mildest atherosclerosis and simple arch anatomy (Group A) (odds ratio [OR], 0.43; 95% confidence interval [CI], 0.31-0.61; P < .001; hazard ratio, 0.42; 95% CI, 0.32-0.57; P < .001). Group B patients with similar atherosclerosis but more complex arch anatomy had 70% lower odds of stroke/death with TCAR compared with TFCAS (OR, 0.30; 95% CI, 0.12-0.75; P = .01). Similar findings were also evident in patients with more severe atherosclerosis and simple arch anatomy (OR, 0.66; 95% CI, 0.44-0.97; P = .037). There was no significant difference in odds of stroke/death in patients with advanced arch atherosclerosis and complex arch (Group D) (OR, 0.91; 95% CI, 0.39-2.16; P = .834). CONCLUSIONS TCAR is safer than TFCAS in patients with simple and advanced arch anatomy. This could be related to the efficiency of flow reversal vs distal embolic protection. The current Centers for Medicare and Medicaid Services decision will likely increase stroke and death outcomes of carotid stenting nationally if multidisciplinary approach and appropriate patient selection are not implemented.

Abstract
INTRODUCTION There is a risk of distal embolization lower extremity endovascular interventions. Possibly a drug-coating embolism caused by coating detachment from intravascular devices. METHODS This review focuses on providing updated information on distal embolism in endovascular revascularization of lower extremity arteries, including the use of drug-coated balloons. RESULTS Drug-coating embolism is a special case of distal embolization during recanalization of the arteries of the lower extremities. Preclinical studies have demonstrated embolization of drug-coated balloons during angioplasty of lower extremity arteries. However, the clinical role of drug-coating embolism is not completely clear. A 2020 meta-analysis found an increased risk of major lower extremity amputation after drug-coated balloon angioplasty in patients with critical limb ischemia. But long-term research is emerging to support the safety of using these devices. Perhaps a more thorough assessment of the quality of life and the degree of compensation of lower limb ischemia with an intraoperative assessment of the frequency of peripheral embolizations using ultrasound emboli detection, as well as microcirculation with transcutaneous oximetry and laser Doppler flowmetry of the operated lower limb will allow a more detailed study of the phenomenon of drug-coating embolism and its impact on long-term clinical outcomes. CONCLUSION According to the results of preclinical studies, the use of paclitaxel-coated balloons leads to an increase in the concentration of paclitaxel in distal skeletal muscles. However, paclitaxel concentration in skeletal muscle was significantly higher in first-generation DCBs. The non-target effects of drug-coating balloon are not fully understood and require further study. Understanding the phenomenon of drug-coating embolism can help physicians to better assess the patient risk and to minimize complications.

Abstract
OBJECTIVE Transfemoral carotid artery stenting (TFCAS) in symptomatic elderly patients (≥70 years old) may have a high periprocedural stroke rate. This study was performed to examine whether tailored TFCAS for symptomatic elderly patients is as safe as that for symptomatic nonelderly patients. METHODS The subjects were 185 patients with symptomatic internal carotid artery stenosis. Tailored TFCAS including postoperative management was performed based on preoperative examinations of vascular anatomy, plaque imaging, platelet aggregation activity, and cerebral hemodynamic impairment. The major 30-day perioperative stroke rates were examined. RESULTS The patients included 51 (27.6%) <70 (group Y) and 134 (72.4%) ≥70 (group E) years old. Group E included significantly more cases with an elongated aortic arch, tortuous target lesion, and longer plaques (all P < 0.05). Among all cases, 181 (97.8%) procedures were performed as per preoperative planning. Group E had more frequent use of a proximal embolic protection device and a closed-cell or dual-layer micromesh stent (all P < 0.05). Seven patients (3.8%) had major stroke. Rates of major ischemic stroke (2.0% vs. 3.0%, P = 1.00) and intracranial hemorrhage (2.0% vs. 0.8%, P = 0.48) were low and did not differ significantly between groups Y and E. CONCLUSIONS Symptomatic elderly patients have several unfavorable factors. However, tailored TFCAS for each patient based on preoperative examinations in symptomatic elderly patients may be as safe as that in symptomatic nonelderly patients.

Abstract
PURPOSE This single center study aims to compare the treatment outcomes and procedure-related complications of coil embolization in elderly patients (60-79 years) and very elderly patients (aged 80 years or older) with cerebral aneurysms. METHODS Data was collected from 504 elderly patients aged 60 years or older who underwent coil embolization for intracranial aneurysms from 2018 to 2021. The study evaluated patient-related and anatomical factors and assessed various outcomes, comparing results between groups using statistical analysis and propensity score matching. RESULTS A total of 503 cerebral aneurysms were analyzed from individuals aged 60-79 years (n = 472) and those aged 80 years or older (n = 31). The majority of the aneurysms were unruptured with an average size of 3.5 mm in height and 3.4 mm in width. The patients were compared using 1:1 propensity score matching, and no significant differences were found in factors other than age and aortic elongation. Logistic analysis revealed that being over 80 years old and having a severe aortic arch elongation were identified as risk factors for procedure-related events in both total and unruptured cases. CONCLUSIONS The study compared coil embolization treatment for cerebral aneurysms in patients aged 60-79 and over 80, finding no significant difference in treatment outcomes except for procedure-related events. Procedure-related events were associated with severe aortic arch elongation and being over 80 years old. Coil embolization can be considered safe and effective for patients over 80, but further trials are needed for accurate conclusions.

Abstract
OBJECTIVE The outcomes of patients with premature cerebrovascular disease (age ≤55 years) who undergo carotid artery stenting are not well-defined. Our study objective was to analyze the outcomes of younger patients undergoing carotid stenting. METHODS The Society for Vascular Surgery Vascular Quality Initiative was queried for transfemoral carotid artery stenting (TF-CAS) and transcarotid artery revascularization (TCAR) procedures between 2016 and 2020. Patients were stratified based on age ≤55 or >55 years. Primary endpoints were periprocedural stroke, death, myocardial infarction (MI), and composite outcomes. Secondary endpoints included procedural failure (defined as ipsilateral restenosis ≥80% or occlusion) and reintervention rates. RESULTS Of the 35,802 patients who underwent either TF-CAS or TCAR, 2912 (6.1%) were ≤55 years. Younger patients were less likely than older patients to have coronary disease (30.5% vs 50.2%; P < .001), diabetes (31.5% vs 37.9%; P < .001), and hypertension (71.8% vs 89.8%; P < .001), but were more likely to be female (45% vs 35.4%; P < .001) and active smokers (50.9% vs 24.0%; P < .001) Younger patients were also more likely to have had a prior transient ischemic attack or stroke than older patients (70.7% vs 56.9%; P < .001). TF-CAS was more frequently performed in younger patients (79.7% vs 55.4%; P < .001). In the periprocedural period, younger patients were less likely to have a MI than older patients (0.3% vs 0.7%; P < .001), but there was no significant difference in the rates of periprocedural stroke (1.5% vs 2.0%; P = .173) and composite outcomes of stroke/death (2.6% vs 2.7%; P = .686) and stroke/death/MI (2.9% vs 3.2%; P = .353) between our two cohorts. The mean follow-up was 12 months regardless of age. During follow-up, younger patients were significantly more likely to experience significant (≥80%) restenosis or occlusion (4.7% vs 2.3%; P = .001) and to undergo reintervention (3.3% vs 1.7%; P < .001). However, there was no statistical difference in the frequency of late strokes between younger and older patients (3.8% vs 3.2%; P = .129). CONCLUSIONS Patients with premature cerebrovascular disease undergoing carotid artery stenting are more likely to be African American, female, and active smokers than their older counterparts. Young patients are also more likely to present symptomatically. Although periprocedural outcomes are similar, younger patients have higher rates of procedural failure (significant restenosis or occlusion) and reintervention at 1-year follow-up. However, the clinical implication of late procedural failure is unknown, given that we found no significant difference in the rate of stroke at follow-up. Until further longitudinal studies are completed, clinicians should carefully consider the indications for carotid stenting in patients with premature cerebrovascular disease, and those who do undergo stenting may require close follow-up.

Abstract
PURPOSE This article presents the evolution of the subject of vascular anatomy and discusses the associated clinical applicability. METHODS Clinically-driven surgical examples met in our everyday practice were used to depict characteristic anatomical paradoxes raised by the inconsistencies between classical anatomical perception, current imaging modalities and modern surgical techniques. RESULTS Consequent anatomy-driven modifications of medical devices comprise a characteristic example of the vivid, modern and meaningful role that anatomy can have on clinical decision-making and improvement of technical and clinical success. Clinical experience provides a feedback that shifts the focus of anatomic research towards new fields of interest, such as the role of arterial collateral networks as therapeutic targets. The clinical feedback brings into light queries and issues where traditional anatomical answers may be vague and inadequate to apply, thereby necessitating further research, refinement and reevaluation. CONCLUSION While the traditional teaching of vascular anatomy is based on information and illustrations derived from dissection and prosection courses, the development of modern imaging technologies applied in large numbers of living patients and application of minimally invasive techniques challenge our understanding of what should be perceived as fixed and permanent. Moreover, the recently introduced evidence-based philosophy in anatomy elaborate more robust data which not only update, validate and enrich the existing knowledge of anatomical variations but also enable subgroup analyses with respect to race, age and sex, identifying specific anatomic features associated with a significant impact on patient treatment.

Abstract
BACKGROUND Guiding catheter (GC) advancement into the target carotid artery is a crucial step in neuroendovascular therapy. In difficult anatomies, alternative methods have been reported to overcome difficult carotid access for swift GC advancement. However, studies focusing on the positional relationship between the GC and inner catheter (IC) at the aortic arch are lacking. METHODS We evaluated the impact of the positional relationship between the GC and IC on whether the GC position affects catheter support or system straightening. We retrospectively reviewed 89 patients who underwent neuroendovascular therapy. We assessed the time to carotid access across difficult arch anatomies. The GC position was divided into Position 1, descending aorta level; Position 2, aortic arch level; and Position 3, origin of the left common carotid artery or innominate artery. We also evaluated the GC support and straightening effects in an in vitro vascular model study. RESULTS The coaxial catheter flexion angle at the aortic arch was significantly larger when the GC was set to Position 3 (p < 0.0001). A significantly shorter time to carotid access was observed with Positions 2 and 3 than with Position 1 in the difficult arch anatomy group. In the in vitro vascular model evaluation, the catheter support effect significantly increased as the GC position became closer to the IC tip (p < 0.0001) and straightening effect significantly increased as the GC moved to Position 2 from Position 1 (p < 0.0001). CONCLUSION During GC advancement, the GC positional relationship changed the support of the coaxial system with system straightening. The optimal GC position, Position 3, facilitated swift GC advancement.

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 In endovascular treatment, it is important to evaluate the access route for placing a catheter into the common carotid artery (CCA) promptly and safely prior to the procedure. We examined whether non-contrast MRA using time-spatial labeling inversion pulse (Time-SLIP) can be used in patients prior to endovascular thrombectomy for acute ischemic stroke. We compared Time-SLIP MRA to contrast-enhanced (CE) MRA and evaluated the efficacy in the evaluation of access routes. Methods We retrospectively reviewed 31 patients admitted between October 2018 and December 2018 for cerebral infarction at our hospital. Blood vessels were imaged from the aortic arch to the CCA. A radiologist blindly evaluated quality score, stenosis, shape of the aorta, and degree of tortuosity. Results There were no "non-diagnostic" images. The sensitivity, specificity, positive predictive value, and negative predictive value for stenosis were 83%, 96%, 83%, and 96%, respectively. The sensitivity for the aorta type classification was 100%. The sensitivity for mild tortuosity was 93%, for moderate was 100%, and for severe was 100%. Conclusion Time-SLIP MRA can be an alternative to CE MRA in access route assessment for patients with cerebral infarction who are not eligible for acute thrombectomy therapy.

Abstract
PURPOSE Unfavorable vascular anatomy can impede thrombectomy in patients with acute ischemic stroke. The aim of this study was to determine the prevalence of aortic arch types, aortic arch branching patterns and supra-aortic arterial tortuosity in stroke patients with large vessel occlusion. METHODS Computed tomography (CT) and magnetic resonance (MR) images of all stroke patients in an institutional thrombectomy registry were retrospectively reviewed. Aortic arch types and branching patterns of all patients were determined. In patients with anterior circulation stroke, the prevalence of tortuosity (elongation, kinking or coiling) of the supra-aortic arteries of the affected side was additionally assessed. RESULTS A total of 1705 aortic arches were evaluated. Frequency of aortic arch types I, II and III were 777 (45.6%), 585 (34.3%) and 340 (19.9%), respectively. In 1232 cases (72.3%), there was a normal branching pattern of the aortic arch. The brachiocephalic trunk and the left common carotid artery had a common origin in 258 cases (15.1%). In 209 cases (12.3%), the left common carotid artery arose from the brachiocephalic trunk. Of 1598 analyzed brachiocephalic trunks and/or common carotid arteries, 844 (52.8%) had no vessel tortuosity, 592 (37.0%) had elongation, 155 (9.7%) had kinking, and 7 (0.4%) had coiling. Of 1311 analyzed internal carotid arteries, 471 (35.9%) had no vessel tortuosity, 589 (44.9%) had elongation, 150 (11.4%) had kinking, and 101 (7.7%) had coiling. CONCLUSION With 20%, type III aortic arches are found in a relevant proportion of stroke patients eligible for mechanical thrombectomy. Nearly half of the stroke patients present with supra-aortic arterial tortuosity, mostly arterial elongation.

Abstract
Carotid artery stenting (CAS) is a valid alternative to conventional carotid endarterectomy for treatment of carotid artery stenosis. Distal embolization of atherosclerotic debris causing cerebrovascular accidents during CAS has been the most significant concern limiting widespread application of CAS technology. A variety of embolic protection devices (EPDs) with different mechanism of action, have been designed to minimize the risk of major embolization causing stroke and their use is recommended by current guidelines. Two general types of EPDs are available: proximal protection devices (PPDs) and distal protection devices (DPDs). However, there is no convincing clinical evidence of the clinical superiority of one device over another. This review will examine the different types of available devices and also innovative devices and techniques, including strengths and weaknesses of each, and present the available evidence and rationale for their routine use during CAS.

Abstract
Tortuous aortic arch is always challenging for beginner neuro-interventionalists. Herein, we share our experience of using 3D-printed extracranial vascular simulators (VSs) and the infrared imaging platform (IRIP) in two training courses for diagnostic cerebral angiography in the past 4 years. A total of four full-scale patient-specific carotid-aortic-iliac models were fabricated, including one type I arch, one bovine variant, and two type III arches. With an angiography machine (AM) as the imaging platform for the practice and final test, the first course was held in March 2018 had 10 participants, including three first-year residents (R1), three second-year residents (R2), and four third-year residents (R3). With introduction of the IRIP as the imaging platform for practice, the second course in March 2022 had nine participants, including 3 R1s, 3 R2s, and 3 R3s. The total manipulation time (TMT) to complete type III aortic arch navigation was recorded. In the first course, the average TMT of the first trial was 13.1 min. Among 3 R1s and 3 R2s attending the second trial, the average TMT of the second trial was 3.4 min less than that of the first trial. In the second course using IRIP, the average TMT of the first and second trials was 6.7 min and 4.8 min, respectively. The TMT of the second trial (range 2.2~14.4 min; median 5.9 min) was significantly shorter than that of the first trial (range 3.6~18 min; median 8.7 min), regardless of whether AM or IRIP was used (p = 0.001). Compared with first trial, the TMT of the second trial was reduced by an average of 3.7 min for 6 R1s, which was significantly greater than the 1.7 min of R2 and R3 (p = 0.049). Patient-specific VSs with radiation-free IRIP could be a useful training platform for junior residents with little experience in neuroangiography.

Abstract
PURPOSE The aim of this work was to mechanically characterize a specific active guidewire and catheters that are commercially available, for further implementation into numerical simulation of endovascular navigation towards complex targets. METHODS For the guidewire, 3-point bending tests and bending with added masses were used to obtain the Young moduli of its various components. To study its behavior, the guidewire was activated under "ideal" conditions and its performance was investigated. As for the various catheters, they were measured and 3-point bending tests were conducted to determine their mechanical properties. RESULTS & CONCLUSION The Young moduli of the shaft and the distal tip of the guidewire were determined. We defined a suitable current intensity to activate the guidewire related to an optimal curvature. Then, the time of activation/deactivation was measured at 1.7 s. On the flip side, parts of the catheters were considered either elastic or viscoelastic. In all cases, the rigidity gradients along the various catheters were highlighted. The characterization of the aforementioned surgical tools provides the opportunity to simulate the endovascular nagivation process.

Abstract
BACKGROUND The use of mechanical thrombectomy (MT) for treatment of acute large vessel occlusion has recently increased. Prompt and timely guiding catheter (GC) induction is necessary to improve prognosis of MT and reduce the time for recanalization. However, difficulties in GC induction are encountered in some patients. This GC induction depends mainly on the aortic arch structure. Therefore, this study focused on assessing presence of tracheal shift on chest X-ray images as pre-treatment evaluation method for GC induction due to its wide availability as an indicator for status of the mediastinum. METHODS We retrospectively examined 33 patients who underwent MT at our facilities between April 2017 and March 2021. The patients were divided into two groups according to presence or absence of tracheal shift on chest X-ray images. Background characteristics and treatment courses in these two groups were compared. RESULTS Among 33 patients, tracheal shift was observed on the chest X-ray images of 14 patients. Furthermore, tracheal shift was positively correlated with the time of GC induction (32.9 min vs. 11.6 min, [p < 0.05]) and the female sex (p = 0.03). Additionally, tracheal shift exhibited correlations with multiple risk factors of atherosclerosis (p = 0.04). CONCLUSIONS In patients with tracheal shift, GC induction could be expectedly difficult. Therefore, advanced disinfection of the right upper arm and affected side of the neck during MT in preparation for changing an approach route is required.

Abstract
BACKGROUND AND PURPOSE Carotid angioplasty and stenting (CAS) could be considered for preventing stroke in patients with carotid artery stenosis. This study aimed to determine the incidence and the risk factors of the early and mid-term complications associated with CAS. METHODS This is a retrospective cohort study conducted at Shiraz University of Medical Sciences from March 2011 to March 2019. Patients at high risk and standard risk for carotid endarterectomy were included. The primary composite outcome was defined as stroke, myocardial infarction (MI), and death in the first 30 days after CAS. All-cause mortality, vascular mortality, and stroke were investigated during mid-term follow-up. RESULTS A total of 579 patients (618 CAS) were recruited (mean age: 71.52 years). Overall, 394 (68.40%), 211 (36.63%), 179 (31.07%), and 96 (16.72%) patients had hypertension, dyslipidemia, diabetes mellitus, or were cigarette smokers, respectively. Primary composite outcomes were observed in 2.59% of patients (1.55% stroke, 0.69% MI, and 1.72% death). Atrial fibrillation was a predictor of primary composite outcome in multivariate logistic regression (p = .048). The presence of total occlusion in the contralateral carotid artery was significantly associated with the risk of stroke in univariate logistic regression (p = .041). The patients were followed for a period ranging from 1 to 83 months. The overall survival rate for all-cause mortality was 93.48% at 1 year, 77.24% at 5 years, and 52.92% at 8 years. All-cause mortality was significantly higher among patients with symptomatic carotid stenosis (p = .014). CONCLUSION CAS provides acceptable short-term and mid-term outcomes in a unique population of high- and standard-surgical-risk, symptomatic and asymptomatic, octogenarian, and nonoctogenarian patients.

Abstract
Background and Purpose The vascular tortuosity (VT) of the internal carotid artery (ICA), and vertebral artery (VA) can impact blood flow and neuronal function. However, few studies involved quantitative investigation of VT based on magnetic resonance imaging (MRI). The main purpose of our study was to evaluate the age and gender effects on ICA and VA regarding the tortuosity and flow changes by applying automatic vessel segmentation, centerline tracking, and phase mapping on MR angiography. Methods A total of 247 subjects (86 males and 161 females) without neurological diseases participated in this study. All subjects obtained T1-weighted MRI, 3D time-of-flight MR angiography, and 2D phase-contrast (PC) MRI scans. To generate quantitative tortuosity metrics from TOF images, the vessel segmentation and centerline tracking were implemented based on Otsu thresholding and fast marching algorithms, respectively. Blood flow and velocity were measured using PC MRI. Among the 247 subjects, 144 subjects (≤ 60 years, 49 males/95 females) were categorized as the young group; 103 subjects (>60 years, 37 males/66 females) were categorized as the old group. Results Independent t-test showed that older subjects had higher tortuosity metrics, whereas lower blood flow and velocity than young subjects (p < 0.0025, Bonferroni-corrected). Cerebral blood flow calculated using the sum flux of four target arteries normalized by the brain mass also showed significantly lower values in older subjects (p < 0.001). The age was observed to be positively correlated with the VT metrics. Compared to the males, the females demonstrated higher geometric indices within VAs as well as faster age-related vascular profile changes. After adjusting age and gender as covariates, maximum blood velocity is negatively correlated with geometric measurements. No association was observed between blood flux and geometric measures. Conclusions Vascular auto-segmentation, centerline tracking, and phase mapping provide promising quantitative assessments of tortuosity and its effects on blood flow. The neck arteries demonstrate quantifiable and significant age-related morphological and hemodynamic alterations. Moreover, females showed more distinct vascular changes with age. Our work is built upon a comprehensive quantitative investigation of a large cohort of populations covering adult lifespan using MRI, the results can serve as reference ranges of each decade in the general population.

Abe T, Sakata H, Ezura M, Endo H, Tominaga T. Direct carotid puncture for endovascular surgery of intracranial aneurysms: Technical note for avoiding complications. Surg Neurol Int 2022; 13:69. [PMID: 35242435 PMCID: PMC8888314 DOI: 10.25259/sni_1147_2021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Accepted: 02/02/2022] [Indexed: 11/05/2022] Open
Abstract
Background: While the most intracranial aneurysms are approachable by femoral or brachial artery puncture during endovascular surgery, in some cases, the lesion is difficult to reach due to complications such as the presence of winding pathways. Direct carotid puncture (DCP) is an alternative access approach, despite the potential risk of fatal neck hematoma. Herein, we describe the DCP technique in a series of five patients with intracranial aneurysms, together with its technical considerations. Methods: Patients with intracranial aneurysms who underwent endovascular surgery using DCP were reviewed retrospectively. We selected the 3F to 6F systems for DCP depending on the necessity of adjunctive techniques. To prevent DCP-associated complications, we (1) conducted a micropuncture before introducing the short sheaths, (2) selected the smallest possible size for the system, (3) reversed heparin postoperatively, and (4) performed perioperative intubation/sedation management. Results: Five out of 535 patients underwent DCP in our hospital between 2015 and 2019; successful vascular access was achieved in all cases. Although a minor neck hematoma occurred in one case, the patient did not require additional treatment. According to a literature review, severe neck hematoma requiring rescue therapy occurs in 5 out of 95 cases (5.3%). Conclusion: Although the potential risk of neck hematoma is not negligible, the DCP technique appears to be a safe and effective approach in treating intracranial aneurysms with challenging access routes in cases where perioperative counter measurements are appropriately performed.

The prognostic value of extracranial vascular characteristics on procedural duration and revascularization success in endovascularly treated acute ischemic stroke patients.

Abstract
Introduction Vascular anatomy might affect endovascular treatment success in acute ischemic stroke patients with large vessel occlusion. We investigated the prognostic value of extracranial vascular characteristics on procedural time and revascularization success in patients with large vessel occlusion in the anterior cerebral circulation. Patients and methods We included 828 patients endovascularly treated within 6.5 hours of symptom onset from the Dutch MR CLEAN-Registry. We evaluated aortic arch configuration, stenosis and tortuosity of supra-aortic arteries, and internal carotid arteries (ICAs) on pre-intervention CTA. We constructed logistic prediction models for outcome variables procedural duration (≥60 minutes) and non-successful revascularization (extended thrombolysis in cerebral infarction (eTICI) of 0–2A) using baseline characteristics and assessed the effect of extracranial vascular characteristics on model performance. Results Cervical ICA tortuosity and stenosis ≥99% improved prediction of long procedural duration compared with baseline characteristics from area under the curve of 0.61 (95% CI: 0.57–0.65) to 0.66 (95% CI: 0.62–0.70) (P < 0.001). Cervical ICA tortuosity was significantly associated with non-successful recanalization. Prediction of non-successful revascularization did not improve after including aortic arch elongation, acute take-off angle, aortic variant, origin stenosis of supra-aortic arteries, and cervical ICA tortuosity, with an area under the curve of 0.63 (95% CI: 0.59–0.67) compared with 0.59 (95% CI: 0.55–0.63) (P = 0.11). Conclusion Extracranial vascular characteristics have additional prognostic value for procedural duration, but not for revascularization success, compared with baseline characteristics. Performance of both prediction models is limited in patients treated for large vessel occlusion.

Abstract
Unruptured cerebral aneurysms are increasingly identified in elderly patients as the global life expectancy continues to rise and non-invasive vascular imaging becomes more prevalent. The optimal management of unruptured aneurysms in elderly patients remains controversial. Variability in life expectancy, comorbidities and rupture risk coupled with heterogenous endovascular and surgical treatments contribute to a paucity of clear guidelines, and current management is highly individualized. Elderly patients present unique considerations including frailty, cognitive dysfunction, vasculopathy, reduced life expectancy and overall worse prognosis in case of rupture which shape the risks and likelihood of success of endovascular and microsurgical treatment. In this review, we provide a comprehensive overview of unruptured cerebral aneurysms in the elderly, with a particular focus on the natural history, key challenges associated with advanced age, management and future innovations to further refine treatment.Key MessagesThe management of unruptured cerebral aneurysms in elderly patients remains controversial.Key challenges including frailty, cognitive dysfunction, reduced life expectancy, vasculopathy and poor prognosis with aneurysm rupture add complexity to endovascular and surgical decision making not encountered with younger demographics.A thorough understanding of available treatment options, likelihood of treatment success and associated risks weighed against the risk of aneurysm rupture informs patient discussion and management.

Abstract
Novel biomarkers are advocated to manage carotid plaques. Therefore, we aimed to test the association between textural features of carotid plaque at computed tomography angiography (CTA) and unfavorable outcome after carotid artery stenting (CAS). Between January 2010 and January 2021, were selected 172 patients (median age, 77 years; 112/172, 65% men) who underwent CAS with CTA of the supra-aortic vessels performed within prior 6 months. Standard descriptors of the density histogram were derived by open-source software automated analysis obtained by CTA plaque segmentation. Multiple logistic regression analysis, receiver operating characteristic (ROC) curve analysis and the area under the ROC (AUC) were used to identify potential prognostic variables and to assess the model performance for predicting unfavorable outcome (periprocedural death or myocardial infarction and any ipsilateral acute neurological event). Unfavorable outcome occurred in 17/172 (10%) patients (median age, 79 years; 12/17, 70% men). Kurtosis was an independent predictor of unfavorable outcome (odds ratio, 0.79; confidence interval, 0.65-0.97; p = 0.029). The predictive model for unfavorable outcome including CTA textural features outperformed the model without textural features (AUC 0.789 vs. 0.695, p = 0.004). In patients with stenotic carotid plaque, kurtosis derived by CTA density histogram analysis is an independent predictor of unfavorable outcome after CAS.

PURPOSE OF THE REVIEW To examine current understanding of diverse etiologies of extracranial carotid disease, including clinical and imaging manifestations as well as treatment approaches. RECENT FINDINGS Increasing availability of advanced cerebrovascular imaging modalities continues to elucidate atherosclerotic and nonatherosclerotic carotid steno-occlusive disease as a common culprit of cerebral ischemia. Individualized treatment strategies targeting each etiologic subset would optimize preventive measures and minimize recurrence of cerebral ischemia. SUMMARY Ischemic stroke is a prominent cause of mortality and long-term disability worldwide. The magnified effect of carotid disease warrants constant and close inspection.

Abstract
BACKGROUND The dual-filter Sentinel™ Cerebral Protection System (Sentinel-CPS) is increasingly used during transcatheter aortic valve replacement (TAVR). However, complex vascular anatomy may challenge Sentinel-CPS deployment. AIM OF THE STUDY We sought to investigate the impact of anatomic features of the aortic arch and the supra-aortic arteries on technical device failure of Sentinel-CPS application. METHODS Analysis of the multislice computed tomography pre-TAVR aortograms of all patients undergoing TAVR with Sentinel-CPS between 2016 and 2020 (n = 92) was performed. We investigated the impact of aortic arch anatomy, configuration, and the angles of the supra-aortic arteries, including the determination of vascular tortuosity index on device failure of Sentinel-CPS application. RESULTS The Sentinel-CPS was applied successfully in 83 patients (90.2%). Device failure in nine patients (9.8%) was due to the infeasibility to perform correct deployment of both filters (n = 7) and to obtain peripheral radial access (n = 2). Patients with a failure of Sentinel-CPS application had a higher right subclavian tortuosity index (217 [92-324] vs. 150 [42-252], p = .046), a higher brachiocephalic tortuosity index (27 [5-51] vs. 10 [0-102], p = 0.033) and a larger angulation of the brachiocephalic artery (59° [22-80] vs. 39° [7-104], p = .014) compared with patients with successful application. A brachiocephalic angle more than 59° was predictive for device failure. No differences in aortic arch anatomy or common carotid artery tortuosity were detected between the groups. CONCLUSIONS Brachiocephalic tortuosity was found to be associated with failure of Sentinel-CPS application. Filter-based usage should be avoided in TAVR patients with a brachiocephalic angle more than 59°.

Abstract
OBJECTIVE The concept of frailty has been proposed to capture the vulnerability resulting from aging and has been implemented for the prediction of perioperative outcomes. Carotid artery stenting (CAS) is considered an appropriate minimally invasive procedure for patients considered to high risk to undergo carotid endarterectomy. Recently, the predictive accuracy for perioperative outcomes using the five-item modified frailty index (5mFI) has been reported to be relatively poor for cardiovascular surgery compared with other surgeries. The effects of functional status and the 5mFI on the outcomes after CAS remain unknown. Thus, in the present study, we investigated the relationship between 5mFI, functional status, and perioperative outcomes. METHODS All the patients who had undergone CAS in the Vascular Quality Initiative from November 15, 2016 to December 31, 2018 were included. Good functional status was defined as the ability to perform all predisease activities without restriction using a new variable added to the Vascular Quality Initiative from November 15, 2016 onward. The 5mFI was calculated using functional status and a history of diabetes, chronic obstructive pulmonary disease, congestive heart failure, and hypertension. The perioperative outcomes included in-hospital stroke or death within 30 days after CAS, a prolonged postoperative stay (≥2 days), and non-home discharge. The associations between functional status, 5mFI, and perioperative outcomes were examined using univariate and multivariable logistic regression, adjusting for sex, age, race, degree of stenosis, symptomatic status, and the usage of preoperative medications. An analysis stratified by functional status was also performed. RESULTS Of the 7836 patients, 188 (2.4%) had experienced perioperative stroke or death, 765 (9.8%) had required a non-home discharge, and 2584 (33.0%) had required a prolonged postoperative stay. A higher (≥0.6 vs <0.6) 5mFI score was associated with greater odds of perioperative stroke or death (adjusted odds ratio [aOR], 2.75; 95% confidence interval [CI], 1.42-5.28; P = .003), non-home discharge (aOR, 2.70; 95% CI, 1.89-3.85; P < .001), and a prolonged postoperative length of stay (aOR, 1.96; 95% CI, 1.56-2.46; P < .001). For the predictive accuracy of the perioperative outcomes, the 5mFI model had an area under the curve for in-hospital stroke or death, non-home discharge, and prolonged postoperative length of stay of 0.714, 0.767, and 0.668, respectively. The functional status model was not inferior to the 5mFI model for any of these outcomes. In the subgroup analysis, of the asymptomatic patients, a higher 5mFI score was associated with greater odds of perioperative stroke or death (aOR, 7.08; 95% CI, 2.02-24.48; P = .002), non-home discharge (aOR, 5.87; 95% CI, 2.45-13.90; P < .001), and a prolonged postoperative stay (aOR, 2.60; 95% CI, 1.82-3.71; P < .001). CONCLUSIONS Frailty, as measured using the 5mFI, and functional status were independent predictors of perioperative stroke or death, non-home discharge, and an increased length of stay for patients undergoing CAS. These results were greatly pronounced in asymptomatic patients. The results from the present study, thus, caution against the use of CAS for asymptomatic frail patients.

Abstract
BACKGROUND AND PURPOSE Chronic subdural hematoma embolization, an apparently simple procedure, can prove to be challenging because of the advanced age of the target population. The aim of this study was to compare 2 arterial-access strategies, femoral versus patient-tailored CTA-based frontline access selection, in chronic subdural hematoma embolization procedures. MATERIALS AND METHODS This was a monocentric retrospective study. From the March 15, 2018, to the February 14, 2019 (period 1), frontline femoral access was used. Between February 15, 2019, and March 30, 2020 (period 2), the choice of the frontline access, femoral or radial, was based on the CTA recommended as part of the preoperative work-up during both above-mentioned periods. The primary end point was the rate of catheterization failure. The secondary end points were the rate of access site conversion and fluoroscopy duration. RESULTS During the study period, 124 patients (with 143 chronic subdural hematomas) underwent an embolization procedure (mean age, 74 [SD, 13] years). Forty-eight chronic subdural hematomas (43 patients) were included during period 1 and were compared with 95 chronic subdural hematomas (81 patients) during period 2. During the first period, 5/48 (10%) chronic subdural hematoma embolizations were aborted due to failed catheterization, significantly more than during period 2 (1/95, 1%; P = .009). The rates of femoral-to-radial (P = .55) and total conversion (P = .86) did not differ between the 2 periods. No significant difference was found regarding the duration of fluoroscopy (P = .62). CONCLUSIONS A CTA-based patient-tailored choice of frontline arterial access reduces the rate of catheterization failure in chronic subdural hematoma embolization procedures.

Abstract
Background It is often hard to navigate a 9 French (F) balloon guiding catheter in patients with type III or bovine aortic arch. Also, a common carotid artery stenosis is challenging, because a guidewire cannot be advanced distally. We developed the combination of a 4F Simmons-type catheter and a 6F distal access catheter as a coaxial inner catheter to navigate a 9F balloon guiding catheter to overcome these difficulties. Materials and methods Medical record at our institution was retrospectively reviewed and carotid artery stenting cases in which the 4F Simmons-6F distal access catheter system was employed as a coaxial catheter to navigate a 9F balloon guiding catheter were identified. To construct this system, a 4F 145 cm SY3 (Hanako Medical, Saitama, Japan) and a 6F 118 cm Cerulean DD6 (Medikit Co. Ltd., Tokyo, Japan) were usually employed. A rotating hemostatic valve should be as short as possible and was attached to only a 9F balloon guiding catheter. The length of a 0.035-in. guidewire needed to be 180 cm or longer. Results During the study period, 106 carotid artery stenting cases were identified. Of these, this system was employed in 29 cases that included 5 cases with a steno-occlusive lesion at common carotid artery/external carotid artery, 10 with type III or bovine arch, and 11 harboring both. In all the cases, a 9F balloon guiding catheter was successfully navigated. Conclusion The 4F Simmons-6F distal access catheter system was useful in navigating a 9F balloon guiding catheter in patients with a common carotid artery stenosis, an external carotid artery occlusion, and an in-stent restenosis, especially when they also harbored type III or bovine aortic arch.

Abstract
Patient selection for endovascular intervention in extracranial carotid disease is centered on vascular anatomy. We review anatomical considerations for non-traumatic disease and offer guidelines in patient selection and management. We conducted a systematic literature review without meta-analysis for studies involving anatomical considerations in extracranial carotid intervention for non-traumatic disease. Anatomical considerations discussed included aortic arch variants, degree of vessel stenosis, angulation, tortuosity, and anomalous origins, and atheromatous plaque morphology, composition, and location. Available literature suggests that anatomical risks of morbidity are largely secondary to increased procedural times and difficulties in intervention system delivery. We recommend the prioritization of endovascular techniques on an individual basis in cases where accessible systems and surgeon familiarity provide an acceptable likelihood of rapid access and device deployment.

Abstract
INTRODUCTION The prevention of atherosclerotic plaque fragmentation during carotid artery stenting is a fundamental problem in decreasing the risk of disability of patients. The goal of this review is to clarify whether the stent design can have a decisive impact on the rate of intraoperative and postoperative complications. AREAS COVERED Different designs of the carotid stents are briefed and the advantages and disadvantages of different stent designs are discussed as well as the results of their clinical use. Various solutions are presented to reduce cerebral embolism during carotid artery stenting. EXPERT OPINION There is no conclusive evidence for the benefits of closed cell and hybrid stents. The stent design cannot completely resolve the problem of cerebral embolism. Most of the events of cerebral microembolism occur at the stages of stent delivery rather than protrusion of an atherosclerotic plaque in the long-term follow-up. Most likely, minimization of the risks for periprocedural and postprocedural strokes requires not only the new solutions in stent design as well as the corresponding delivery systems and brain embolic protection systems, but also the new strategies of preprocedural drug stabilization of the atherosclerotic plaque in the carotid artery.

Abstract
Purpose To describe our single-center experience of mechanical thrombectomy (MTE) via a direct carotid puncture (DCP) with regard to indication, time metrics, procedural details, as well as safety and efficacy aspects. Methods DCP thrombectomy cases performed at our center were retrospectively identified from a prospectively maintained institutional MTE database. Various patient (age, sex, stroke cause, comorbidities), clinical (NIHSS, mRS), imaging (occlusion site, ASPECT score), procedural (indication for DCP, time from DCP to reperfusion, materials used, technical nuances), and outcome data (NIHSS, mRS) were tabulated. Results Among 715 anterior circulation MTEs, 12 DCP-MTEs were identified and analyzed. Nine were left-sided M1 occlusions, one right-sided M1 occlusion, and two right-sided M2 occlusions. DCP was successfully carried out in 91.7%; TICI 2b/3-recanalization was achieved in 83.3% via direct lesional aspiration and/or stent-retrieval techniques. Median time from DCP to reperfusion was 23 min. Indications included futile transfemoral catheterization attempts of the cervical target vessels as well as iliac occlusive disease. Neck hematoma occurred in 2 patients, none of which required further therapy. Conclusion MTE via DCP in these highly selected patients was reasonably safe, fast, and efficient. It thus represents a valuable technical extension of MTE, especially in patients with difficult access.

Abstract
BACKGROUND Type III arch configuration is frequently reported as a stroke risk factor for carotid angioplasty and stenting (CAS). We reviewed contemporary guidelines on management of carotid artery stenosis to assess the clinical relevance attributed to this anatomic feature in current clinical practice. METHODS The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The PubMed, EMBASE, and Web of Science databases were searched to identify all guidelines on extracranial carotid disease published between January 2008 and March 2020. A total of 435 articles were screened. For multiple guidelines from the same writing group, only the most recent updated version was considered. Eighteen documents were identified for qualitative analysis. RESULTS Four guidelines specifically reported type III arch as a predictive factor of periprocedural complications after CAS. Two of them also provided a low level of evidence of their recommendation. None of the documents indicated the exact criteria for aortic arch classification. Three different methods to describe type III arch configuration were identified. CONCLUSIONS Type III arch configuration is inconsistently included among stroke risk factors for CAS in contemporary guidelines, and variably defined. Further studies on the level of concordance between the 3 existing definition criteria are warranted.

Complexity of Aortic Arch Anatomy Affects the Outcomes of Transcarotid Artery Revascularization Versus Transfemoral Carotid Artery Stenting. Ann Vasc Surg 2020; 67:78-89. [PMID: 32339690 DOI: 10.1016/j.avsg.2020.04.016] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Revised: 04/09/2020] [Accepted: 04/17/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Transcarotid artery revascularization (TCAR) has been shown to have half the rates of transient ischemic attack (TIA), stroke, and death compared with transfemoral carotid artery stenting (TFCAS). Successful outcomes of TFCAS require careful patient selection. The aim of this study was to determine the outcomes of TFCAS versus TCAR in both simple (type I) and complex (type II and III) aortic arches. METHODS A retrospective cohort study was performed comparing the outcomes of patients undergoing TFCAS versus TCAR with simple and complex aortic arches using the Vascular Quality Initiative registry from August 2011 to May 2019. The primary outcome was a composite of in-hospital TIA/stroke/death. RESULTS About 6,108 carotid artery interventions were analyzed, including 3,536 (57.9%) patients with type I, 2,013 (33.0%) with type II, and 559 (9.2%) with type III aortic arch. In 3,535 patients with a simple arch, 1,917 underwent TFCAS and 1,619 had TCAR. Mean age was 70.6 (±9.5) years, and 2,382 (67.4%) patients were males. The primary outcome of postoperative TIA/stroke/death was seen significantly less frequently in those undergoing TCAR compared with TFCAS in simple arches (odds ratio [OR], 0.63; 95% confidence interval [95% CI], 0.43-0.94; P = 0.0236). Although the individual outcome of death occurred less often in TCAR (P = 0.0025), there was no difference in the occurrence of in-hospital stroke (P = 0.8836) or TIA (P = 0.4608). On multivariable analysis, TCAR was associated with improved outcomes (P = 0.0062). A worse outcome was associated with increasing age (P < 0.001), a prior stroke (P < 0.0001), and increasing number of stents (P = 0.0483). In 2,572 patients with a complex arch, 1,416 underwent TFCAS and 1,156 had TCAR. Mean age was 73.0 (±9.1) years, and 1,655 (64.4%) were males. In complex arch anatomy, the primary outcome of in-hospital TIA/stroke/death was seen significantly less frequently in TCAR compared with TFCAS (OR, 0.49; 95% CI, 0.31-0.77; P = 0.0022). Again noted was a significant difference in death, with better outcomes in TCAR (P = 0.0133). Although the occurrence of in-hospital TIA was no different between the 2 approaches (P = 0.6158), there were significantly fewer strokes in those treated with TCAR (P = 0.0132). TCAR (P = 0.0146) was associated with improved outcomes. A worse outcome was seen with advancing age (P = 0.0003), prior strokes (P = 0.01), and a left-sided lesion (P = 0.0176). CONCLUSIONS TCAR has improved outcomes of TIA/stroke/death compared with TFCAS in both simple and complex aortic arch anatomy. In simple aortic arches, there is no difference in neurologic outcomes between both approaches. In complex arch anatomy, TCAR has fewer strokes.

Abstract
BACKGROUND AND PURPOSE There is a general assumption in the cerebrovascular literature that there is an association between carotid artery tortuosity and connective tissues disease; however, this has not been firmly established. The purpose of this study was to determine the prevalence of carotid artery tortuosity in patients with connective tissue diseases relative to matched controls. MATERIALS AND METHODS Patients with previous CTA or MRA and a diagnosis of connective tissue diseases were identified and compared with a cohort of age-matched controls. Radiologists blinded to the diagnosis reviewed the images and evaluated the presence of carotid artery tortuosity (including loops, kinks, or coils). Continuous variables were compared using the Student t test, and categoric variables with χ2 tests. RESULTS One hundred forty-three patients with connective tissue disease and 143 controls were included in this study. Specific diagnoses included Marfan (n = 33), nonvascular Ehlers-Danlos (n = 36), Ehlers-Danlos vascular-type (n = 32), neurofibromatosis type 1 (n = 26), and Loeys-Dietz (n = 16) syndromes. The presence of carotid tortuosity was 44% in connective tissue disease and 16% in controls (P < .001). Of tortuosity manifestations, coils were most prevalent (23% versus 3%; P < .001). Among the various connective tissue diseases, the rates of any carotid tortuosity were 88% for Marfan syndrome, 63% for Loeys-Dietz syndrome, 42% for neurofibromatosis type 1, and 19% for both vascular- and nonvascular-type Ehlers-Danlos syndrome. The positive predictive value of the combination of aortic aneurysm and carotid tortuosity being associated with connective tissue disease was 95.4%. The specificity was 98.6%. CONCLUSIONS Carotid artery tortuosity is highly associated with connective tissue diseases, particularly Marfan syndrome, Loeys-Dietz syndrome, and neurofibromatosis type 1. Such findings are relevant in risk assessment for vascular complications in connective tissue disease, endovascular treatment planning, and in understanding the pathomechanisms of vascular tortuosity in general.

Abstract
The objective of this study was to compare clinical outcomes in patients who with unfavorable vascular anatomy underwent mechanical thrombectomy (MT) by common carotid artery access versus transfemoral approach.A retrospective review was performed in our hospital database to identify patients with challenging vascular anatomy who underwent MT for anterior circulation large vessel occlusion (LVO) between August 2015 and November 2018. Transcarotid and transfemoral cohorts were compared. Patient characteristics, procedural techniques, clinical outcomes were recorded.A total of 52 patients were included, 16 (31%) underwent MT via transcarotid access. There were no significant differences in patient characteristics, intravenously recombinant tissue plasminogen activator therapy, clot location, or carotid tortuosity and presence of aortic arch type. There were significant differences in clinical outcomes between the 2 cohorts, including mean access-to-reperfusion time (84 vs 44 minutes; P = .000), poor clinical outcome (modified Rankin scale >2) at 90 days follow-up (37.5% vs 63.9%; P = .034). But there were no significant differences in successful revascularization rates (thrombolysis in cerebral infarction score ≥2b 87.5% vs 80.6%; P = .541), post-thrombectomy symptomatic intracranial hemorrhage (12.5% vs 13.9%; P = .892), and mortality (12.5% vs 22.2%; P = .412) were similar between transcarotid and transfemoral cohorts.Our results demonstrate that transcarotid access for MT of anterior circulation LVO in patients with unfavorable vascular anatomy may be considerable. Transcarotid access may be better than transfemoral access in well-selected unfavorable vascular anatomy patients undergoing MT.

Abstract
Background and Purpose- Stenting for symptomatic carotid stenosis (carotid artery stenting [CAS]) carries a higher risk of procedural stroke or death than carotid endarterectomy (CEA). It is unclear whether this extra risk is present both on the day of procedure and within 1 to 30 days thereafter and whether clinical risk factors differ between these periods. Methods- We analyzed the risk of stroke or death occurring on the day of procedure (immediate procedural events) and within 1 to 30 days thereafter (delayed procedural events) in 4597 individual patients with symptomatic carotid stenosis who underwent CAS (n=2326) or CEA (n=2271) in 4 randomized trials. Results- Compared with CEA, patients treated with CAS were at greater risk for immediate procedural events (110 versus 42; 4.7% versus 1.9%; odds ratio, 2.6; 95% CI, 1.9-3.8) but not for delayed procedural events (59 versus 46; 2.5% versus 2.0%; odds ratio, 1.3; 95% CI, 0.9-1.9; interaction P=0.006). In patients treated with CAS, age increased the risk for both immediate and delayed events while qualifying event severity only increased the risk of delayed events. In patients treated with CEA, we found no risk factors for immediate events while a higher level of disability at baseline and known history of hypertension were associated with delayed procedural events. Conclusions- The increased procedural stroke or death risk associated with CAS compared with CEA was caused by an excess of events occurring on the day of procedure. This finding demonstrates the need to enhance the procedural safety of CAS by technical improvements of the procedure and increased operator skill. Higher age increased the risk for both immediate and delayed procedural events in CAS, mechanisms of which remain to be elucidated. Clinical Trial Registration- URL: https://clinicaltrials.gov .

Abstract
Objective To determine the safety and efficacy of flow reversal following proximal flow arrest as an embolic protection strategy for carotid angioplasty and stenting (CAS) with short-term follow-up. Method We performed a retrospective review of our CAS database for patients who underwent stent-supported carotid revascularization in the setting of acute/subacute stroke or TIA. We reviewed clinical and radiographic data during a 36-month period. Primary outcome was clinical evidence of ipsilateral stroke in the first 30 days. Secondary outcomes include clinical outcomes and sonographic and/or angiographic follow-up over 6 months, 6-month functional scale, and all-cause mortality. Results Fifty-five patients underwent CAS using flow reversal: 26 females and 29 males with a mean age of 69.7 years. Median time to treatment from index event was 3 days. 11% underwent stenting as part of hyperacute stroke therapy. Average luminal stenosis was 86%. The 9-Fr Mo.Ma device was used in combination with Penumbra aspiration in all cases. There were no ipsilateral strokes. Incidence of any ischemic event was 3.64%, but only 1 (1.82%) patient had a postoperative stroke. Clinical follow-up was available for 94.5%, while lesion follow-up was available for 73% of patients. Three patients had evidence of restenosis, but none were symptomatic. Luminal restenosis was ≤30% in all three. Median pre- and post-NIHSS were 1 and 1, respectively. Conclusion Flow reversal using the Mo.Ma device is a safe and effective strategy in preventing distal embolization during carotid artery revascularization.

Vascular Anatomy and Not Age is Responsible for Increased Risk of Complications in Symptomatic Elderly Patients Undergoing Carotid Artery Stenting. World Neurosurg 2019; 128:e513-e521.

Abstract
BACKGROUND Various studies have suggested that age ≥80 years is associated with a higher rate of complications after carotid artery stenting (CAS). The Buffalo Risk Assessment Scale (BRASS) predicts complications in symptomatic patients undergoing CAS. Application of the BRASS has shown the ability to improve patient selection. We used the BRASS system to evaluate whether the higher rate of complications associated with CAS in the elderly is related to vascular anatomy. METHODS A retrospective review of CAS was performed at our institution over 7 years. Demographic information, anatomic characteristics, BRASS categorization, and outcome measures were compared between elderly (≥80 years) and younger patients (<80 years). RESULTS The study included 447 patients: 335 patients (75%) <80 years and 112 patients (25%) ≥80 years. There were significantly more elderly patients in the high-risk BRASS category (P < 0.01), and more young patients in the low-risk BRASS category (P = 0.04). The complication rates in the 2 groups were similar. Older patients were more likely to harbor complex vascular anatomy: they had significantly higher rates of types II and III aortic arches (P = 0.01 and P < 0.01, respectively), higher percentage of tortuous carotid vessels (P < 0.01), and higher rates of hostile anatomy for deployment of distal embolic protection devices (P = 0.02). CONCLUSIONS Complex vascular anatomy, rather than age, is the key factor behind the higher CAS-associated complication rate in the elderly. Complications can be avoided through proper patient selection and stratifying patients based on anatomic characteristics, which can be achieved through the BRASS scoring system.

Abstract
PURPOSE Carotid artery stenting (CAS) is a valuable alternative to carotid endarterectomy, especially in high-risk patients. However, the reported incidences of perioperative stroke and death remain higher than for carotid endarterectomy, even when using embolic protection devices (EPDs) during CAS. Our purpose was to evaluate 30-day major adverse events after CAS when selecting the most appropriate EPD. METHODS We reviewed the clinical outcomes of 61 patients with 64 lesions who underwent CAS with EPDs. Patients who underwent CAS associated with thrombectomy and who had a preoperative modified Rankin scale score >3 were excluded from the analysis. The EPD was selected based on symptoms, carotid wall magnetic resonance imaging and lesion length, and we analyzed combined 30-day complication rates (transient ischemic attack, minor stroke, major stroke or death). RESULTS Forty-nine patients were men and 12 were women. The median age was 72 years (range: 59-89 years) and 44 lesions were asymptomatic. A filter-type EPD was selected in 23 procedures, distal-balloon protection in 14 procedures and proximal-occlusive protection in 27 procedures. Two patients (3.1%) experienced a transient ischemic attack and one patient (1.6%) had a minor stroke within 30 days of the procedure. No patients experienced procedure-related morbidities (modified Rankin score >2) or death. CONCLUSIONS The perioperative stoke rate was low when we selected a proximal-occlusive-type EPD in high-risk patients with vulnerable carotid artery disease. Our algorithm for EPD selection was an effective tool in the perioperative management of carotid artery stenosis.

Abstract
AIMS The aim of the present study was to evaluate periprocedural and 30-day outcomes in a prospective series of patients treated with the CGuard Embolic Prevention System (EPS). METHODS AND RESULTS From April 2015 to June 2016, a physician-initiated prospective multicentre study was performed in 200 consecutive patients admitted for protected carotid artery stenting (CAS) and treated using the CGuard EPS in twelve vascular centres. Outcome measures were: technical success, periprocedural (0-24 hours) and post-procedural (24 hours-30 days) major and minor strokes, death, acute myocardial infarction (AMI), transient ischaemic attack (TIA), and external carotid occlusion. In three centres, consecutive diffusion-weighted magnetic resonance cerebral imaging (DW-MRI) was performed ≤72 hours prior to and within 72 hours after the intervention. A distal embolic protection device was employed in 182 patients (91%). Technical success was 100%. No death, AMI or major stroke occurred periprocedurally. There were two TIAs and five periprocedural minor strokes (2.5%), including one thrombosis solved by surgery. In the remaining patients (199/200; 99.5%) one-month follow-up duplex ultrasound revealed optimal technical results. Post-procedural clinical follow-up was uneventful. No external carotid artery occlusion occurred. New post-procedural DW-MRI lesions were detected in 12 patients out of 61 (19.6%), including bilateral in five (8.2%) and isolated ipsilateral in six (9.8%), whereas one patient (1.6%) had contralateral only lesions. CONCLUSIONS Multicentre multi-specialty use of the CGuard EPS in routine clinical practice was associated with no major periprocedural neurologic complications and a total elimination of post-procedural neurologic complications by 30 days.

PURPOSE To examine the safety profile of transcervical access (TCA) in comparison with the transfemoral approach (TFA) in carotid artery stenting. MATERIALS AND METHODS A systematic review and meta-analysis was performed according to current guidelines. Eleven eligible studies including 11,592 patients (10,736 in the TFA group and 856 in the TCA group) were identified through a search of the PubMed, Scopus, and Cochrane databases up to October 2018. A random effects model meta-analysis was conducted, and the I2 statistic was used to assess heterogeneity. Publication bias was assessed using funnel plots and quantified using the Egger method. RESULTS The TFA group had a statistically significantly higher risk of periprocedural (30-day) stroke compared with the TCA group (OR 1.98, 95% CI 1.08 to 3.63, p=0.027; I2=0%). Also, patients in the TFA group had a significantly higher risk of developing new ischemic lesions (OR 2.97, 95% CI 1.48 to 5.96, p=0.002; I2=0%) on diffusion-weighted magnetic resonance imaging (DW-MRI). No differences in terms of transient ischemic attack (OR 1.50, 95% CI 0.73 to 3.10, p=0.268; I2=5.9%), myocardial infarction (OR 0.64, 95% CI 0.30 to 1.35; p=0.242; I2=0%), local hematoma (OR 0.53, 95% CI 0.12 to 2.25, p=0.389; I2=0%), or mortality (OR 1.35, 95% CI 0.62 to 2.92, p=0.449; I2=0%) were identified between the groups. CONCLUSION TCA is associated with a significantly lower risk for periprocedural stroke and DW-MRI ischemic lesions compared with TFA. Other periprocedural outcomes were similar between the groups.

World Neurosurg 2019; 125:e110-e116. [PMID: 30677582 DOI: 10.1016/j.wneu.2018.12.216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2018] [Revised: 12/26/2018] [Accepted: 12/28/2018] [Indexed: 10/27/2022]
Abstract
OBJECTIVE The purpose of this study was to investigate neck movement and various conditions of the aortic arch that may hinder access to the carotid artery during neurointerventional procedures. METHODS We reviewed 230 patients who underwent internal carotid artery angiography between February 2016 and October 2016. Use of a Davis catheter (DC) was first attempted and if not possible, movement (right, left, flexion, and extension) of the patient's head was tried before catheter exchange. We analyzed the success rate after neck motion in relation to various aortic arch factors. RESULTS Only extension of the patient's neck was effective. Of the 209 patients with right side angiography, 23 had failed access with a DC, but neck extension was effective in 3 patients (13%). Failure to insert a DC was significantly correlated with age, male sex, acute angle, arch elongation, aortic calcification, and carotid artery angulation on the right side, whereas access was not gained in 24 out of 208 patients who underwent left side angiography, and neck extension was successful in 7 patients (29.2%). Also, significant factors determining the catheter exchange were age, male sex, acute angle, arch elongation, and aortic calcification.In the DC access failure group, neck extension was significantly more effective for younger aged patients (P = 0.011). CONCLUSIONS Factors such as older age, acute arch angle, higher elongation type, arch calcification, and carotid artery angulation were verified as factors affecting access by a simple catheter; however, neck extension was shown to facilitate access in about 10%-30% of patents.

Efficacy of carotid artery stenting on stroke prevention of octogenarians. Clin Neurol Neurosurg 2018; 173:187-193. [PMID: 30165319 DOI: 10.1016/j.clineuro.2018.08.027] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2018] [Revised: 07/15/2018] [Accepted: 08/20/2018] [Indexed: 11/16/2022]
Abstract
OBJECTIVES Octogenarians account for a third of ischemic stroke (IS) patients and applying endovascular carotid artery stenting (CAS), as a secondary prevention, in these patients is challenging. The aim of this study was to evaluate peri-procedural and long term clinical and angiographic impact of CAS on octogenarians. PATIENTS AND METHODS In a prospective study, 102 patients aged over 80 years old with symptomatic internal carotid artery (ICA) stenosis presenting by non-disabling IS or transient ischemic attack and having undergone CAS were evaluated prospectively from January 2012 to July 2016. All patients received standard stroke care during the study follow up period. Peri-procedural complication, cerebrovascular accidents, restenosis in target vessel and mortality rate were recorded and the collected data were analyzed to evaluate safety and durability of CAS in octogenarians. RESULTS 48 (47.06%) males and 54 (52.9%) females with the mean age of 83.39 ± 2.53 (range, 80-88) years were followed in a mean period of 24.5 ± 14.1 months (6-50 months). Success rate of CAS was 100%; whereas, the peri-procedural complication rate was 5.8% (only one patient experienced acute ischemic stroke during the procedure). Restenosis and recurrent cerebrovascular accidents were observed in 3.9% and 9.8% of the cases, respectively. Recurrent cerebrovascular accident leading to death was seen in 2.9% of the cases. The median patient event-free survival was 20 months. CONCLUSION Endovascular CAS seems to be a safe and durable method for secondary prevention in ischemic stroke following symptomatic carotid artery stenosis in octogenarians.
