Abstract
PURPOSE Aim of the study was to evaluate the influence of sex in asymptomatic patients undergoing carotid artery stenting (CAS). MATERIALS AND METHODS A retrospective observational study was conducted from January 2006 to December 2020. A total of 438 consecutive patients with asymptomatic carotid artery stenosis >70% underwent transfemoral CAS and were stratified in males (M) and females (F). Periprocedural 30-day outcomes were: stroke, death, and myocardial infarction (MI). Follow-up outcomes were: death and stroke rates (primary) and freedom from restenosis (FFR) and reintervention rates (secondary). Follow-up data were analyzed at 1, 5, and 10 years. Data were analyzed with χ2 test and Fisher's exact test and follow-up outcomes with Kaplan-Meier curves. The log-rank test was used to determine differences between the groups and univariate analysis to identify the association between risk factors and intraoperative details with mortality and restenosis rates. RESULTS A total of 462 procedures were performed (M: n=321, 69.4%), in which 24 CAS were bilateral (5.5%). Mean age was 71.9±7.6 years (M: 72.1±7.8; F: 71.7±7.3). Periprocedural outcomes were: stroke rate 2.2% (n=10; M: n=5, 1.6%; F: n=5, 3.5%; p=0.176), mortality rate 0.6% (M: n=3, p=0.334), and stroke/death rate 2.8% (n=13; M: n=8, 2.5%; F: n=5, 3.5%; p=0.528); no cardiac events (MI) were recorded. A not-disabling (minor) stroke was detected in 3 males (0.9%), while a disabling (major) stroke was reported in 7 patients (1.7%) of whom 5 were ischemic events (M: n=2, 0.6%; F: n=3, 2.2%) and 2 were cerebral hemorrhages (F: 1.3%, p=0.046). Mean follow-up was 73.66±40.83 months (M: 72.66; F: 76.01; p=0.246). Overall survival rate was 96.1% (95% confidence interval [CI]: 93-98), 81.8% (95% CI: 77-86), and 45.5% (95% CI: 38-53) at 1, 5, and 10 years, respectively (p=0.236). The overall stroke rate was 0.3% (freedom from stroke [FFS]: 99.7%; 95% CI: 98-100), 0.9% (FFS: 99%; 95% CI: 98-100), and 4.3% (FFS: 95.7%; 95% CI: 89-98; M: n=6; F: n=2; p=0.774). Stroke-related mortality rate was 0.7% (FFS: 99.3%; 95% CI: 97-100) and 2.9% (FFS: 97.1%; 95% CI: 91-99) at 5 and 10 years, respectively, without differences between the groups (M: n=4; F: n=2; p=0.763). Overall FFR rate was 97.4% (95% CI: 95-99), 93.4% (95% CI: 90-96), and 89.5% (95% CI: 84-93; p=0.322). Two severe symptomatic restenosis (>70%, M) required a new endovascular revascularization. CONCLUSION The sex variable does not influence outcomes of CAS in asymptomatic patients at short- and long-term follow-up, although females show a worst incidence of periprocedural major strokes. Carotid artery stenting may be safely proposed when a careful patient selection is applied. CLINICAL IMPACT The sex variable has been advocated as a considerable factor that could influence the outcomes of transfemoral carotid artery stenting (CAS). Literature data are contrasting, even if different papers mainly reported that CAS is associated to worst outcomes in female patients. Our study shows that the sex-variable does not influence outcomes of CAS in asymptomatic patients at short and long-term follow-up, although females had a worst incidence of periprocedural major strokes. CAS may be safely proposed when a careful patient selection is applied.

Abstract
Atherosclerotic carotid artery disease is a significant cause of stroke in the United States and globally. Its prevalence increases with age and it is more prevalent in men and White and Native-American populations. However, the outcomes related to carotid disease are worse in women and Black patients. Research suggests the disparities exist due to a multitude of factors, including disease pathophysiology, access to care, provider bias, and socioeconomic status. The prevalence of carotid stenosis in the general population is low (3%), and routine screening for carotid stenosis is not recommended in adults. Randomized clinical trials have shown benefits of stroke risk reduction with surgery (carotid endarterectomy or stenting) for symptomatic patients. Management is controversial in asymptomatic patients, as modern medical management has results equivalent to those of surgery and ongoing randomized clinical trials will address this important question. Carotid surgery is not appropriate in asymptomatic patients with limited life expectancy. Future work should explore comprehensive care models for care of patients with carotid disease and assessment of patient-reported outcomes to measure quality of care.

Abstract
Objetives. Carotid endarterectomy (CEA) is an established treatment for carotid stenosis (CS). However, this procedure is not risk-free and it is insufficient to control disseminated atherosclerosis. Our aim was to determine long-term cardiovascular morbidity and mortality after CEA and identify associated risk predictors. Design. Consecutive cohorts of CEAs performed between 2010 and 2018 in two Portuguese hospitals were retrospectively analysed. The major end-points were acute myocardial infarction (AMI), stroke, all-cause death and major adverse cardiovascular events (MACE). Results. 248 patients (mean age 69 years; 79% male) were enrolled in the study. 24% had postoperative complications. At 52 months median follow-up, 9 ± 2.0% (mean ± standard error) of patients experienced an acute myocardial infarction (AMI), 12 ± 2.4% a stroke and 26 ± 3.2% a MACE. All-cause mortality rate was 21 ± 3.0%. Multivariate analysis identified coronary artery disease (CAD) as significant predictor of AMI (p < .001; Hazard Ratio (HR):9.628; 95% Confidence Interval (95%CI):2.805-33.046), whereas no statistically significant risk factor of stroke was found. Predictors of death included left sided CS (p = .042; HR:1.886; 95%CI:1.024-3.475), chronic kidney disease (CKD) (p = .007; HR:2.352; 95%CI:1.266-4.372) and anticoagulant medication (p = .015; HR:2.107; 95%CI:1.216-6.026), while statin use was significantly protective (p = .049; HR:0.482; 95%CI:0.233-0.998). Concerning MACE, male gender (p = .040; HR:1.709; 95%CI:1.025-2.849), tobacco use (p = .004; HR:2.181; 95%CI:1.277-3.726), CAD (p = .002; HR:2.235; 95%CI:1.340-3.727) and CKD (p < .001; HR:3.029; 95%CI:1.745-5.258) were risk predictors. Conclusions. Patients continue to have high rates of AMI, MACE and death after CEA. Prior CAD is a risk factor for future AMI, whereas CKD is a significant predictor of MACE and death. Aggressive best medical treatment and risk factors modification should be advised in all patients with systemic atherosclerosis.

Analysis of the ROADSTER pivotal and extended-access cohorts shows excellent 1-year durability of transcarotid stenting with dynamic flow reversal. J Vasc Surg 2019; 69:1786-1796. [PMID: 30611582 DOI: 10.1016/j.jvs.2018.08.179] [Citation(s) in RCA: 70] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Accepted: 08/16/2018] [Indexed: 11/30/2022]
Abstract
OBJECTIVE We report the 1-year outcomes of the Safety and Efficacy Study for Reverse Flow Used During Carotid Artery Stenting Procedure (ROADSTER) multicenter trial. This trial introduced a novel transcarotid neuroprotection system (NPS), the ENROUTE transcarotid NPS (Silk Road Medical Inc, Sunnyvale, Calif). Postoperative results demonstrated that the use of the ENROUTE transcarotid NPS is safe and effective. The aim of this study was to evaluate the safety of transcarotid artery revascularization (TCAR) and to present the 1-year outcomes. METHODS This study is a prospective, single-arm clinical trial. Current enrollment occurs in 14 centers. Primary end points were incidence rates of ipsilateral stroke at 1 year after TCAR. Occurrence of stroke was ascertained by an independent Clinical Events Committee. Patients with anatomic or medical high-risk factors for carotid endarterectomy (CEA) were eligible to be enrolled in the ROADSTER trial. RESULTS Overall, 165 patients were included in the long-term follow-up (112 of 141 patients from the pivotal phase and 53 of 78 patients from the extended access). Mean age was 73.9 years (range, 42.1-91.3 years). Patients aged 75 years and older were 43.3% of the cohort. The majority of patients were white (92.7%) and male (75.2%). Most patients were asymptomatic (79.9%). Anatomic risk factors were distributed as follows: contralateral carotid artery occlusion (11.0%), tandem stenosis of >70% (1.8%), high cervical carotid artery stenosis (25.0%), restenosis after CEA (25.6%), bilateral stenosis requiring treatment (4.3%), and hostile neck (14.6%). Medical high-risk criteria included two-vessel coronary artery disease (14.0%) and severe left ventricular dysfunction with ejection fraction <30% (1.8%). In general, 43.3% of patients had at least one anatomic high-risk factor, whereas 29.9% of patients had medical high-risk factors. Both subsets of factors were present simultaneously in 26.8% of the cohort. At 1-year follow-up, ipsilateral stroke incidence rate was 0.6%, and seven patients (4.2%) died. None of the deaths were neurologic in origin. CONCLUSIONS TCAR with dynamic flow reversal had previously shown favorable 30-day perioperative outcomes. This excellent performance seems to extend to 1 year after TCAR as illustrated in this analysis. The promising results from the ROADSTER trial likely stem from the novel cerebral protection provided through the ENROUTE transcarotid NPS in comparison to distal embolic protection devices as well as the transcarotid approach's circumventing diseased aortic arch manipulation and minimizing embolization. TCAR offers a safe and durable revascularization option for patients who are deemed to be at high risk for CEA.

[PMID: 28745403 PMCID: PMC5655705 DOI: 10.1002/bjs.10600] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2017] [Revised: 04/15/2017] [Accepted: 04/20/2017] [Indexed: 11/07/2022]
Abstract
BACKGROUND The UK abdominal aortic aneurysm (AAA) screening programmes currently invite only men for screening because the benefit in women is uncertain. Perioperative risk is critical in determining the effectiveness of screening, and contemporary estimates of these risks in women are lacking. The aim of this study was to compare mortality following AAA repair between women and men in the UK. METHODS Anonymized data from the UK National Vascular Registry (NVR) for patients undergoing AAA repair (January 2010 to December 2014) were analysed. Co-variables were extracted for analysis by sex. The primary outcome measure was in-hospital mortality. Secondary outcome measures included mortality by 5-year age groups and duration of hospital stay. Logistic regression was performed to adjust for age, calendar time, AAA diameter and smoking status. NVR-based outcomes were checked against Hospital Episode Statistics (HES) data. RESULTS A total of 23 245 patients were included (13·0 per cent women). Proportionally, more women than men underwent open repair. For elective open AAA repair, the in-hospital mortality rate was 6·9 per cent in women and 4·0 per cent in men (odds ratio (OR) 1·48, 95 per cent c.i. 1·08 to 2·02; P = 0·014), whereas for elective endovascular AAA repair it was 1·8 per cent in women and 0·7 per cent in men (OR 2·86, 1·72 to 4·74; P < 0·001); the results in HES were similar. For ruptured AAA, there was no sex difference in mortality within the NVR; however, in HES, for ruptured open AAA repair, the in-hospital mortality rate was higher in women (33·6 versus 27·1 per cent; OR 1·36, 1·16 to 1·59; P < 0·001). CONCLUSION Women have a higher in-hospital mortality rate than men after elective AAA repair even after adjustment. This higher mortality may have an impact on the benefit offered by any screening programme offered to women.

Abstract
BACKGROUND Women have been shown to experience inferior outcomes following intact and ruptured abdominal aortic aneurysm (AAA) treatment in endovascular aneurysm repair (EVAR) and open surgical repair (OSR) groups. The goal of our study was to compare gender-specific presentation, management, and early outcomes after AAA repair using a statewide registry. METHODS We utilized the Washington State's Vascular Interventional Surgical Care and Outcomes Assessment Program registry data collected in 19 hospitals from July 2010 to September 2013. Demographics, presentation, procedural data, and outcomes in elective and emergent AAA repair groups were analyzed. RESULTS We identified 1,231 patients (19.6% women) who underwent intact (86.4%) or ruptured AAA (13.6%) repairs. Nine thousand seventy-two (79.0%) patients had EVAR and 259 (21.0%) had OSR. Men and women were of equivalent age and had similar comorbidities, except that women had less coronary artery disease (P < 0.01) and were more likely to suffer from chronic obstructive pulmonary disease (P = 0.05). Women had smaller aneurysm diameters (5.8 ± 1.1 vs. 6.2 ± 1.8 cm, P < 0.01) at the time of presentation and men had slightly higher incidence of rupture at larger aneurysm size. Men were more likely to undergo EVAR, with significant differences in elective (82.1% vs. 74.1%, P = 0.01), but not ruptured repair. Women had significantly higher mortality rates following elective EVAR (3.1% vs. 0.6%, P = 0.01), but not after ruptured or elective open repair. Following elective EVAR, women were less likely to be discharged to home after longer hospital stays (3 vs. 2 days, P < 0.01). CONCLUSIONS Despite presentation at a similar age, with a smaller aneurysm diameter, and similar medical comorbidities, women experience substantially worse hospital outcomes primarily driven by elective endovascular procedures. Utilization of endovascular techniques in women still remains lower compared with men. Improvement of elective outcomes in women will likely depend on technical advancements in repair techniques and management strategies that may differ between genders.

Abstract
Background Stroke is the number one cause of disability and third leading cause of death among adults in the United States. A major cause of stroke is carotid artery stenosis (CAS) caused by atherosclerotic plaques. Randomized trials have varying results regarding the equivalence and perioperative complication rates of stents versus carotid endarterectomy (CEA) in the management of CAS. Objectives We review the evidence for the current management of CAS and describe the current concepts and practice patterns of CEA. Methods A literature search was conducted using PubMed to identify relevant studies regarding CEA and stenting for the management of CAS. Results The introduction of CAS has led to a decrease in the percentage of CEA and an increase in the number of CAS procedures performed in the context of all revascularization procedures. However, the efficacy of stents in patients with symptomatic CAS remains unclear because of varying results among randomized trials, but the perioperative complication rates exceed those found after CEA. Conclusions Vascular surgeons are uniquely positioned to treat carotid artery disease through medical therapy, CEA, and stenting. Although data from randomized trials differ, it is important for surgeons to make clinical decisions based on the patient. We believe that CAS can be adopted with low complication rate in a selected subgroup of patients, but CEA should remain the standard of care. This current evidence should be incorporated into practice of the modern vascular surgeon.
