Abstract
BACKGROUND Persistent hypotension (PH) after carotid artery stenting (CAS) is a relatively common complication; however, it is unclear which patients are more likely to experience this phenomenon. Recently, lower left atrial (LA) volume was associated with vasovagal syncope, which has a similar neurological mechanism to hypotension after CAS. This study aimed to investigate whether LA volume can predict PH after CAS. METHODS This single center retrospective analysis used data from 316 patients who had undergone CAS between March 2013 and February 2021. After the exclusion of urgent CAS, 212 procedures (202 patients) with transthoracic echocardiograms were included. The procedures were divided among two groups according to the presence or absence of PH for more than 1 hour after CAS. RESULTS The mean age of the patients was 73.0±7.5 years. PH was observed during 52 (24.5%) procedures. The PH group exhibited a lower LA volume index (LAVI) than the no-PH group (29.7±9.1 vs 37.7±12.5 mL/m2, respectively; p<0.001). The area under the receiver operating characteristic curve was 0.716. The optimal cut-off value was 33.5 mL/m2 (sensitivity 0.750, specificity 0.625). Multiple logistic regression analysis showed that LAVI <33.5 mL/m2 was an independent predictor for PH after CAS (OR 4.950, 95% CI 2.190 to 11.200; p<0.001). Preoperative hydration was negatively associated with PH (OR 0.235, 95% CI, 0.070 to 0.794; p=0.020). CONCLUSIONS A lower LA volume can predict PH after CAS, and preoperative hydration may prevent PH after CAS.

Abstract
OBJECTIVE The purpose of this study was to investigate the details of minor complications of carotid artery stenting in a developing country. METHODS This was a retrospective, single-center study conducted on the target group consisting of 65 symptomatic patients who underwent carotid artery stenting. We assessed technical success rate, periprocedural complication within 30 days (hypotension, bradycardia, acute kidney injury, vasospasm, a transient ischemic attack, stroke, myocardial infarction, and death), and the differences between groups with and without complications. RESULTS Minor periprocedural complications occurred in 15 patients. In all, 8 (12.3%) had transient hypotension, 6 (9.2%) had bradycardia, 7 (10.7%) had acute kidney injury, 2 (3.1%) had vasospasm, and 1 (1.5%) had transient ischemic attack. A greater rate of minor complications was observed in women (p=0.051). CONCLUSION The results of the carotid artery stenting procedures performed in a developing country were acceptable.

Clinical Outcomes of Second- versus First-Generation Carotid Stents: A Systematic Review and Meta-Analysis. J Clin Med 2022; 11:jcm11164819. [PMID: 36013058 PMCID: PMC9409706 DOI: 10.3390/jcm11164819] [Citation(s) in RCA: 31] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2022] [Revised: 07/20/2022] [Accepted: 07/29/2022] [Indexed: 01/10/2023] Open
Abstract
Background: Single-cohort studies suggest that second-generation stents (SGS; “mesh stents”) may improve carotid artery stenting (CAS) outcomes by limiting peri- and postprocedural cerebral embolism. SGS differ in the stent frame construction, mesh material, and design, as well as in mesh-to-frame position (inside/outside). Objectives: To compare clinical outcomes of SGS in relation to first-generation stents (FGSs; single-layer) in CAS. Methods: We performed a systematic review and meta-analysis of clinical studies with FGSs and SGS (PRISMA methodology, 3302 records). Endpoints were 30-day death, stroke, myocardial infarction (DSM), and 12-month ipsilateral stroke (IS) and restenosis (ISR). A random-effect model was applied. Results: Data of 68,422 patients from 112 eligible studies (68.2% men, 44.9% symptomatic) were meta-analyzed. Thirty-day DSM was 1.30% vs. 4.11% (p < 0.01, data for SGS vs. FGS). Among SGS, both Casper/Roadsaver and CGuard reduced 30-day DSM (by 2.78 and 3.03 absolute percent, p = 0.02 and p < 0.001), whereas the Gore stent was neutral. SGSs significantly improved outcomes compared with closed-cell FGS (30-day stroke 0.6% vs. 2.32%, p = 0.014; DSM 1.3% vs. 3.15%, p < 0.01). At 12 months, in relation to FGS, Casper/Roadsaver reduced IS (−3.25%, p < 0.05) but increased ISR (+3.19%, p = 0.04), CGuard showed a reduction in both IS and ISR (−3.13%, −3.63%; p = 0.01, p < 0.01), whereas the Gore stent was neutral. Conclusions: Pooled SGS use was associated with improved short- and long-term clinical results of CAS. Individual SGS types, however, differed significantly in their outcomes, indicating a lack of a “mesh stent” class effect. Findings from this meta-analysis may provide clinically relevant information in anticipation of large-scale randomized trials.

Abstract
According to the American Heart Association, ischemic stroke is the second leading cause of death globally and is responsible for approximately 11% of deaths. Carotid endarterectomy (CEA) is the standard treatment for moderate or severe extracranial internal carotid artery (ICA) stenoses. With the development of materials and technology in neurointervention, the Centers for Medicare and Medicaid Services (CMS) have proposed that carotid artery stenting (CAS) can serve as an alternative treatment for CEA. As CAS is widely used worldwide, comorbidities, especially persistent hemodynamic depression (PHD) and stroke, have attracted public attention. In this review, we summarized the current advances in PHD after CAS. A better understanding of CAS-related PHD may inspire the design of potential prognostic and therapeutic tools.

Abstract
BACKGROUND AND AIMS Evaluation of arterial stiffness and carotid atherosclerotic burden can provide important prognostic information regarding the risk of future cardiovascular events. The aim of this study was to assess these vascular properties in patients with diabetes mellitus (DM). METHODS AND RESULTS In the context of the observational "Corinthia" study, we analyzed 1757 participants with determined DM status. Carotid ultrasonography was performed to evaluate intima-media thickness (cIMT) and carotid plaque burden. Arterial stiffness was estimated via assessment of carotid-to-femoral pulse wave velocity (cfPWV). Individuals with DM had increased mean cIMT, maximum cIMT, carotid plaque burden, and cfPWV compared to those without DM. After multivariable regression analysis, the presence of DM was still associated with significantly increased mean cIMT (by 0.074 mm, p = .004), maximum cIMT (by 0.134 mm, p = .007), cfPWV (by 0.929 m/s, p < .001), and a higher prevalence of carotid plaques (odds ratio 1.52, 95% confidence intervals 1.11, 2.10, p = .01). In a propensity score-matched cohort, mean cIMT, maximum cIMT, and carotid plaque burden were significantly higher in individuals with DM. Analysis according to territory of cIMT measurement displayed substantial differences in left (DM: 1.32 ± 0.78 mm vs. no DM: 1.20 ± 0.66 mm, p = .04) and right carotid bulbs (DM: 1.33 ± 0.82 mm vs. no DM: 1.18 ± 0.69 mm, p = .02) with respect to DM status while non-significant variations were observed in left (DM: 0.98 ± 0.49 mm vs. no DM: 0.91 ± 0.35 mm, p = .06) and right common carotid artery (DM: 0.95 ± 0.50 mm vs. no DM: 0.92 ± 0.40 mm, p = .36). CONCLUSIONS Diabetes mellitus is associated with increased cfPWV and cIMT, with more pronounced lesions in the carotid bulb.

Abstract
Carotid artery stenting (CAS) involves dilatation of carotid bulb which can trigger a series of neuronal responses resulting in hemodynamic depression that might influence the outcome of the procedure. This is a frequent but underdiagnosed complication of CAS. Although it is mild, transient and self-limiting in majority of cases, it can result in significant morbidity and mortality if persistent. Neurologists should be aware of the predisposing factors and management of this common complication. In patients who present with stroke following carotid stenting, neurologists should be aware of hypoperfusion secondary to hemodynamic depression as a cause of stroke apart from the stent thrombosis and occlusion.

Abstract
Background: Carotid angioplasty stenting (CAS) may have adverse events including perioperative hemodynamic depression. A transvenous temporary cardiac pacemaker (TTCP) is an option for preventing devastating sequelae due to circulatory failure. An exploration of the predictors of hemodynamic depression following CAS is valuable for selecting candidates for preoperative TTCP implantation before CAS. Case Description: An 84-year-old man underwent CAS for asymptomatic left carotid severe stenosis. He had no history of bradycardia arrhythmia. A TTCP was implanted in advance in view of the likelihood of perioperative hemodynamic depression. CAS was accomplished successfully, but severe hypotension and vanishing of self-heartbeat occurred about 90 min after the procedure. By activating the pre-implanted TTCP, spontaneous circulation was readily recovered with vasopressor administration. He was discharged with no additional neurological deficits. A literature review using a random effect model found that smoking (odds ratio [OR] 1.68, 95% confidence interval (CI) 1.13–2.52) and severely calcified plaque (OR 3.70, 95% CI 2.15–6.35) were significant predictors of perioperative hemodynamic depression following CAS. Conclusion: TTCP can be recommended for a patient receiving CAS to prevent catastrophic consequences, particularly in cases with a history of smoking or severely calcified plaque.

Abstract
OBJECTIVE Carotid artery stenting (CAS) is a major treatment option for carotid artery stenosis, and a recognized alternative to carotid endarterectomy (CEA). However, CAS-related hemodynamic instability occurs frequently and is a known major risk factor of associated complications. This study was undertaken to identify the risk factors of hemodynamic instability associated with CAS. METHODS We analyzed the medical records of 128 patients with carotid artery stenosis treated by CAS at our institution from 2014 to 2019 to identify the risk factors of hemodynamic instability after CAS. In addition, the incidences of hemodynamic instability, including bradycardia and hypotension, during and after the procedure were investigated. RESULTS Overall, periprocedural bradycardia requiring atropine occurred in 18 (14.1 %) of the 128 study subjects, and postprocedural persistent hypotension requiring vasopressors occurred in 15 (11.7 %). Risk-adjusted analysis showed carotid bulb involvement of a stenotic lesion was an independent risk factor of periprocedural bradycardia (OR 4.25, 95 % CI 1.34-13.40) and postprocedural persistent hypotension (OR 7.36, 95 % CI 1.86-29.12). However, though a preoperative regimen of ≥ 2 antihypertensives was found to be an independent protective factor against postprocedural persistent hypotension (OR 0.17, 95 % CI 0.04-0.81), it was not associated with periprocedural bradycardia (OR 0.37 95 % CI 0.08-1.60). CONCLUSIONS The risk of hemodynamic instability development is greater when a carotid stenotic lesion involves the carotid bulb, which cautions that careful evaluation is necessary. In addition, the receipt of antihypertensive regimens before CAS had a protective effect on persistent hypotension after CAS, but did not affect bradycardia.

Abstract
BACKGROUND Hemodynamic changes frequently occur after carotid artery stenting (CAS), and in some patients these changes, particularly hypotension, may be prolonged. There are discrepant results for predicting patients at high risk for these prolonged hemodynamic changes and identifying the effect on clinical outcome. In this study, we aimed to determine the frequency, predictors and consequences associated with prolonged hypotension (PH) after CAS in our center. METHODS We retrospectively analyzed the demographics, risk factors, nature of carotid disease, degree of stenosis of both internal carotid arteries, stent diameter and site of dilatation during stenting in 137 CAS procedures. After CAS, duration of hospital stay, complications during hospital stay and major vascular events or death in a 3-month period were evaluated. PH was defined as a systolic blood pressure <90 mmHg lasting more than 1 h despite adequate treatment after CAS. RESULTS PH occured in 23 (16.8%) patients. The presence of contralateral stenosis ≥70% and absence of diabetes mellitus were significantly associated with PH. Duration of hospital stay was significantly longer in patients with PH. No patients with PH had a periprocedural complication or major vascular events in the follow-up period. CONCLUSION PH was more prevalent in patients with contralateral high-degree carotid stenosis and patients without diabetes mellitus after CAS. PH did not cause any post-procedural complications or major vascular events at follow-up, but it resulted longer hospital stays. Further studies are needed to better define the pathophysiologic mechanisms underlying these hemodynamic alterations.

Abstract
BACKGROUND Cerebral hyperperfusion syndrome or hemodynamic instability, caused by the hemodynamic changes, often occur within 6 hr after carotid artery stenting (CAS) The postprocedure cerebral hemodynamic change in the early phase, <6 hr after CAS, is largely unknown. In this study, we evaluated the cerebral hemodynamic changes in patients after CAS using transcranial Doppler (TCD). METHODS From January 2013 to July 2014, medical records of 61 patients who underwent CAS were reviewed retrospectively. Among them, 44 patients had TCD examination before CAS, 1-2 and 3-4 hr after CAS. In the TCD examination, middle cerebral artery (MCA) peak systolic velocity (PSV) and pulsatility index (PI) on the ipsilateral and contralateral sides were measured. Blood pressure, MCA PSV, and PI data were collected and analyzed from the 44 patients who had valid TCD examinations. RESULTS Blood pressure was 148.4 ± 14.5 mm Hg before CAS: 124.5 ± 13.8 mm Hg 1-2 hr after CAS, and 121.6 ± 12.6 mm Hg 3-4 hr after CAS. On the ipsilateral side, the MCA PSV increased from 85.7 ± 22.8 cm/s before CAS to 101.1 ± 27.1 cm/s (19.9%, P < 0.001) 1-2 hr after CAS, and 99.7 ± 27.0 cm/s (18.2%, P < 0.001) 3-4 hr after CAS. There was no significant difference in MCA PSV between 1-2 and 3-4 hr after CAS (P = 0.200). The PI increased from 0.871 ± 0.167 before CAS to 0.941 ± 0.205 (P = 0.022) 1-2 hr after CAS, and 0.954 ± 0.218 (P = 0.010) 3-4 hr after CAS. On the contralateral side, there was no statistically significant PSV increase in the MCA following CAS. CONCLUSIONS CAS may induce a significant increase in PSV and PI in the ipsilateral MCA within 4 hr. The MCA PSV increased significantly higher than that on the contralateral side. The PSV had no significant change between 1-2 and 3-4 hr after CAS.

Abstract
A significant controversy exists regarding the clinical impact of hemodynamic depression on major adverse events after carotid artery stenting (CAS). The purpose of this study was to evaluate the incidence, predictors, and clinical significance of hypotension after CAS. A total of 118 cases of carotid artery stenosis were treated with CAS. Hypotension was defined as sustained systolic blood pressure <80 mmHg and requiring intravenous administration of vasopressor to maintain adequate systolic blood pressure after the procedure. Baseline characteristics, procedural characteristics, and periprocedural major adverse events were retrospectively compared between postprocedural hypotension group and non-hypotension group. Morphological and procedural characteristics were not significantly different between the two groups. Periprocedural major adverse events, presence of new ischemic lesions, and number of new ischemic lesions were not significantly different between the two groups (P = 1, P = 0.36, P = 0.68). Hypertension was an independent protective factor (P = 0.037), and use of proximal protection and the distance from carotid bifurcation to maximum stenotic lesion ≤ 10 mm were independent risk factors for developing hypotension after CAS (P = 0.034, P = 0.027). There was no significant relationship between hypotension after CAS and major adverse events in this study. Maintenance of periprocedural adequate cerebral perfusion is thought to be important to prevent ischemic complications due to hypotension after CAS, especially in these cases.

Abstract
Carotid artery angioplasty with stenting (CAS) is being performed in many hospitals in Korea. Most of the guidelines which are being used are similar, but the practical aspects such as techniques are different between hospitals. For example, usage of various protective devices, the oral antiplatelet regimen prior to procedure and placing of temporary pacemaker to prevent bradycardia are different between hospitals. In this article, we summarize and propose the guidelines for CAS which is currently being accepted in Korea. These guidelines may be helpful in providing protocol to neurointerventionalist who perform CAS and to standardize the process including reporting of CAS in the future comparative trials in Korea.
