Abstract
This systematic review aimed to identify sex-specific outcomes in men and women after carotid endarterectomy (CEA) and carotid artery stenting (CAS), including transfemoral and transcarotid. A search of literature published from January 2000 through December 2022 was conducted using key terms attributed to carotid interventions on PubMed. Studies comparing outcome metrics post intervention (ie, myocardial infarction [MI], cerebral vascular accident [CVA] or stroke, and long-term mortality) among male and female patients were reviewed. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Overall, all studies reported low rates of perioperative complications. Among the studies that did not stratify outcomes by the preoperative symptom status, there were no significant sex differences in rates of perioperative strokes or MIs. Two studies, however, noted a higher rate of 30-day mortality in male patients undergoing CEA than in female patients. Analysis of asymptomatic patients undergoing CEA revealed no difference in perioperative MIs (female: 0% to 1.8% v male: 0.4% to 4.3%), similar rates of CVAs (female: 0.8% to 5% v male: 0.8% to 4.9%), and no significant differences in the long-term mortality outcomes. Alternatively, symptomatic patients undergoing CEA reported a higher rate of CVAs in female patients vs. male patients (7.7% v 6.2%) and showed a higher rate of death in female patients (1% v 0.7%). Among studies that did not stratify outcome by symptomatology, there was no difference in the 30-day outcomes between sexes for patients undergoing CAS. Asymptomatic patients undergoing CAS demonstrated similar incident rates across perioperative MIs (female: 0% to 5.9% v male: 0.28% to 3.3%), CVAs (female: 0.5% to 4.1% v male: 0.4% to 6.2%), and long-term mortality outcomes (female: 0% to 1.75% v male: 0.2% to 1.5%). Symptomatic patients undergoing CAS similarly reported higher incidences of perioperative MIs (female: 0.3% to 7.1% v male: 0% to 5.5%), CVAs (female: 0% to 9.9% v male: 0% to 7.6%), and long-term mortality outcomes (female: 0.6% to 7.1% v male: 0.5% to 8.2%). Sex-specific differences in outcomes after major vascular procedures are well recognized. Our review suggests that symptomatic female patients have a higher incidence of neurologic and cardiac events after carotid interventions, but that asymptomatic patients do not.

Abstract
BACKGROUND We aimed to further evaluate sex differences of perioperative and 30-day complications after carotid surgery in patients with both asymptomatic and symptomatic carotid artery stenosis. METHODS This was a single-center prospective cohort study including 2013 consecutive patients, who were treated surgically due to extracranial carotid artery stenosis and prospectively followed. Patients who underwent carotid artery stenting and who were treated conservatively were excluded. The primary endpoints for this study were hospital stroke/transitory ischemic attack (TIA) and overall survival rates. Secondary outcomes included all other hospital adverse events, 30-day stroke/TIA, and 30-day mortality rates. RESULTS Hospital mortality was higher in female patients with symptomatic carotid stenosis (3% vs. 0.5%, P=0.018). Bleeding requiring re-intervention occurred more often in female patients with both asymptomatic (1.5% vs. 0.4%, P=0.045) and symptomatic carotid stenosis (2.4% vs. 0.2%, P=0.022). 30-day stroke/TIA and mortality rates were higher in female patients with both asymptomatic (stroke/TIA 4.4% vs. 2.5%, P=0.041; mortality 3.3% vs. 1.6%, P=0.046) and symptomatic carotid stenosis (stroke/TIA 8.3% vs. 4.2%, P=0.040; mortality 4.1% vs. 0.7%, P=0.006). After adjusting for all confounding factors, female gender remained an important predicting factor for 30-day stroke/TIA in asymptomatic (OR=1.4, 95%CI 1.0-4.7, P=0.041) and symptomatic patients (OR=1.7, 95%CI 1.1-5.3, P=0.040), as well as for 30-day all-cause mortality in patients with asymptomatic (OR=1.5, 95%CI 1.1-4.1, P=0.030) and symptomatic carotid artery disease (OR=1.2, 95%CI 1.0-5.2, P=0.048). CONCLUSIONS Female gender is important predicting factor for stroke/TIA and all-cause mortality, both perioperative and during the first 30 days after carotid surgery.

Carotid Endarterectomy for Symptomatic Carotid Stenosis: Differences in Patient Profile in a Low-Middle-Income Country. Cerebrovasc Dis Extra 2022; 13:56-62. [PMID: 36481594 PMCID: PMC10080201 DOI: 10.1159/000528515] [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: 10/11/2022] [Accepted: 11/20/2022] [Indexed: 12/13/2022] Open
Abstract
INTRODUCTION Carotid endarterectomy (CEA) is the standard treatment for patients with symptomatic carotid stenosis. Data from low- and middle-income countries are sparse on CEA and its outcomes. We aimed to describe the profile of our patients and factors associated with periprocedural cerebral ischemic events in patients with symptomatic carotid stenosis who underwent CEA in our institute. METHODS Retrospective review of patients with symptomatic carotid stenosis (50-99%) who underwent CEA between January 2011 and December 2021 was done. Clinical and imaging parameters and their influence on periprocedural cerebral ischemic events were analyzed. RESULTS Of the 319 patients (77% males) with a mean age of 64 years (SD±8.6), 207 (65%) presented only after a stroke. Majority (85%) had high-grade stenosis (≥70%) of the symptomatic carotid. The mean time to CEA was 50 days (SD±36); however, only 26 patients (8.2%) underwent surgery within 2 weeks. Minor strokes and TIA occurred in 2.2%, while major strokes and death occurred in 4.1% patients. None of the clinical or imaging parameters predicted the periprocedural cerebral ischemic events. The presence of co-existing significant (≥50%) tandem intracranial atherosclerosis (n = 77, 24%) or contralateral occlusion (n = 24, 7.5%) did not influence the periprocedural stroke risk. CONCLUSION There is a delay in patients undergoing CEA for symptomatic carotid stenosis. Majority have high-grade stenosis and present late only after a stroke reflecting a lack of awareness. CEA can be performed safely even in patients with significant intracranial tandem stenosis and contralateral carotid occlusion.

Abstract
BACKGROUND We aim to identify gender differences in complications after carotid surgery. Our primary endpoint is the incidence of perioperative stroke, myocardial infarction, and mortality. Secondary endpoints include restenosis and reintervention rates. METHODS All patients undergoing carotid endarterectomy from July 2003 to May 2016 were reviewed. The Society for Vascular Surgery carotid reporting standards were used as a guideline for data collection. RESULTS Over 13 years, 9,585 patients with carotid disease were referred to our institution. A total of 690 procedures were performed (633 carotid endarterectomies, 54 carotid angioplasties and stenting, and 3 bypasses). Of these 633 carotid endarterectomy procedures, 31.8% (201) were in women and 68.2% (432) were in men. In the perioperative period, female gender was found to be an independent predictor of stroke (odds ratio [OR]: 8.597, 95% confidence interval [CI]: 0.967-76.429, P = 0.041), restenosis (OR: 2.103, 95% CI: 1.445-3.060, P < 0.001), and reintervention (OR: 6.448, 95% CI: 1.313-31.667, P = 0.019). Mortality and cardiac morbidity did not significantly differ between genders. Ten-year stroke-free survival was 98.0% in women and 99.1% in men (logrank P = 0.259). Ten-year restenosis-free survival was 77.6% (45 of 201) in women and 89.4% (45 of 425) in men (logrank P < 0.001). Ten-year reintervention-free survival was 97.0% in women and 99.5% in men (logrank P = 0.008). Female gender was not an independent predictor of myocardial infarction (P = 0.713) and mortality (P = 0.856), respectively. The mean follow-up time was 47.06 ± 37.48 months with a median follow-up time of 43 months (interquartile range: 14.0-72.5). CONCLUSIONS Female gender was an independent predictor of postoperative stroke, restenosis, and reintervention. Symptom status at the time of surgery and type of closure of the arteriotomy did not influence development of stroke in female patients.

Abstract
AIM Compare the basic characteristics of patients and to examine the existence of higher rates of perioperative complications (0 - 30 days) in women versus men after carotid endarterectomy (CEA). METHODS This is a retrospective-prospective study included 270 patients with significant stenosis of carotid in whom CEA was performed, during the period from 2012 to 2017. Patients they were divided: group 1 - 100 female patients, group 2 - 170 male patients. RESULTS No statistically significant age difference was observed between the two groups, group 1 - 66.01 years (SD 8.42, 46 to 86 years), group 2 - 66.46 years (SD 8.03, 47 to 85 years) (p = 0.659). Risk factors represent a greater prevalence in group 2, but the observed difference is not statistically significant. The average duration of surgery and the time of carotid artery clamping time were longer in group 1: (p = 0.002; p = 0.005). The number of classic endarterectomy with the patch was higher in women (41 (41%) versus 31 (18. 2%), p = 0.005), while the number of bilateral CEAs was not statistically significant. CONCLUSION The results of this study of this study did not indicate a greater presence of perioperative complications (< 30 days) in women versus male patients after CEA.

Abstract
Recurrent carotid stenosis is an ongoing process that may develop at or near the site of an operational or interventional procedure to treat an atheromatous stenosis. Although such a restenosis is most often initially without symptoms, as the disease progresses it may become symptomatic, and thus endanger the patient's life. Such patients are therefore candidates for revisional surgery. Extensive research investigation and numerous studies have incriminated several risk factors as predisposing conditions for recurrent carotid stenosis. The definite role of each predisposing factor, however, is still widely debated. Clarifying the extent of involvement of each factor in the pathogenesis of carotid restenosis is indeed demanding, as it would contribute enormously to the identification of the group of high-risk patients, and, therefore, determine the therapeutic approach in these patients.

Abstract
Background Subgroup analyses from randomized controlled trials (RCT) of carotid endarterectomy (CEA) for both symptomatic and asymptomatic carotid stenosis suggest less benefit in women compared to men, due partly to higher age-independent peri-operative risk. However, a meta-analysis of case series and databases focussing on CEA-related gender differences has never been investigated. Methods A systematic review of all available publications (including case series, databases and RCTs) reporting data on the association between sex and procedural risk of stroke and/or death following CEA from 1980 to 2015 was investigated. Pooled Peto odds ratios of the procedural risk of stroke and/or death were obtained by Mantel-Haenszel random-effects meta-analysis. The I2 statistic was used as a measure of heterogeneity. Potential publication bias was assessed with the Egger test and represented graphically with Begg funnel plots of the natural log of the OR versus its standard error. Additional sensitivity analyses were undertaken to evaluate the potential effect of key assumptions and study-level factors on the overall results. Meta-regression models were formed to explore potential heterogeneity as a result of potential risk factors or confounders on outcomes. A tria sequential analysis (TSA) was performed with the aim to maintain an over- all 5 % risk of type I error, being the standard in most meta- analyses and systematic reviews. Results 58 articles reported combined stroke and mortality rates within 30 days of treatment. In the unselected overall meta-analysis, the incidence of stroke and death in the male and female groups differed significantly (Peto OR, 1,162; 95 % CI, 1.067-1.266; P = .001), revealing a worse outcome for female patients. Moderate heterogeneity among the studies was identified (I2 = 36 %), and the possibility of publication bias was low (P = .03). In sensitivity analyses the meta-analysis of case series with gender aspects as a secondary outcome showed a significantly increased risk for 30-day stroke and death in women compared to men (Peto OR, 1.390; 95 % CI, 1.148-1.684; P = .001), In contrast, meta-analysis of databases (Peto OR, 1.025; 95 % CI, 0.958-1.097; P = .474) and case series with gender related outcomes as a primary aim (Peto OR, 1.202; 95 % CI, 0.925-1.561; P = .168) demonstrated no increase in operative risk of stroke and death in women compared to men. Conclusions Metanalyses of case series and databases dealing with CEA reveal inconsistent results regarding gender differences related to CEA-procedure and should not be transferred into clinical practice.

Abstract
OBJECTIVE Historically, large randomized controlled studies looking at carotid endarterectomy (CEA) have indicated an increased perioperative risk for women when gender subgroup analysis was performed. However, the outcomes of carotid stenting in women as compared to men have not been adequately investigated. We sought to compare the safety and efficacy of carotid angioplasty and stenting (CAS) when performed in women as compared to men. METHODS Procedures, complications, demographics, co-morbidities, and follow-up data from carotid stenting procedures performed in a bi-campus division were entered into a prospective database and then retrospectively supplemented with stored angiographic image data and reviewed. Arterial anatomic characteristics evaluated using angiographic images were: common carotid/internal carotid lesion length ratio, common carotid/internal carotid diameter, index lesion length, common carotid/internal carotid artery tortuosity, and lesion and aortic arch calcification. Outcomes compared included groin complications, postoperative pressor requirements, length of stay, restenosis, stroke, myocardial infarction (MI), and death. RESULTS Between 2003 and 2008, 228 patients underwent 238 procedures. Cerebral protection devices and self-expanding stents were placed in all patients. A total of 97 percutaneous interventions performed in 93 women were compared with 141 interventions in 135 men. Mean age in women was 71.8 +/- 9.2 years, in men was 72.2 +/- 9.1 years (P > .99); 44.3% of women and 34.7% of men had symptomatic disease (P = .14). Preoperative demographics and co-morbidities did not differ significantly between genders, with the exception of hypertension (83.0% of males vs 96.7% of females, P = .001), and history of coronary artery bypass grafting (31.8% of males vs 16.1% of females, P = .01). There were no significant differences seen in anatomic arterial characteristics, though there was a trend towards women having larger internal carotid to common carotid diameter ratios (0.65 vs 0.62) and more plaques isolated to the common carotid segment (9.5% vs 6.9%). There were no significant differences seen in overall 30-day peri-procedural stroke rate (2.1% in women and 4.2% in men, P = .48), death rate (0 % vs 0.7%, P > .99), or cardiac events (3.2% vs 0.7%, P = .3). The combined 30-day stroke, death, and MI rate was 5.7% for males compared to 5.4% for females (P > .99). There were no differences observed in the long-term survival, stroke-free survival, or restenosis between genders. CONCLUSION Despite previous concerns over adverse outcomes in women undergoing carotid endarterectomy, from our data, carotid stenting appears to be a safe modality in women with equivalent outcomes when compared to men.

Abstract
OBJECTIVE Specific guidelines for management of cerebrovascular risk in women are currently lacking. This study aims to provide a consensus expert opinion to help make clinical decisions in women with carotid stenosis. METHODS Proposals for the use of carotid endarterectomy (CEA), carotid stenting (CAS), and medical therapy for stroke prevention in women with carotid stenosis were provided by a group of 9 international experts with consensus method. RESULTS Symptomatic women with severe carotid stenosis can be managed by CEA provided that the perioperative risk of the operators is low (<4%). Periprocedural stroke risks may be increased in symptomatic women if revascularization is performed by CAS; however, the choice of CAS vs CEA can be tailored in subgroups best fit for each procedure (e.g., women with restenosis or severe coronary disease, best suited for CAS; women with tortuous vessels or old age, best suited for CEA). There is currently limited evidence to consider medical therapy alone as the best choice for women with neurologically severe asymptomatic carotid stenosis, who should be best managed within randomized trials including a medical arm. Medical management and cardiovascular risk factor control must be implemented in all women with carotid stenosis in periprocedural period and lifelong regardless of whether or not intervention is planned. CONCLUSIONS The suggestions provided in this article may constitute a decision-making basis for planning treatment of carotid stenosis in women. Most recommendations are of limited strength; however, it is unlikely that new robust data will emerge soon to induce relevant changes.

In-hospital versus postdischarge adverse events following carotid endarterectomy. J Vasc Surg 2013; 57:1568-75, 1575.e1-3. [PMID: 23388394 DOI: 10.1016/j.jvs.2012.11.072] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2012] [Revised: 11/12/2012] [Accepted: 11/17/2012] [Indexed: 12/12/2022]
Abstract
OBJECTIVE Most studies based on state and nationwide registries evaluating perioperative outcome after carotid endarterectomy (CEA) rely on hospital discharge data only. Therefore, the true 30-day complication risk after carotid revascularization may be underestimated. METHODS We used the National Surgical Quality Improvement Program database 2005-2010 to assess the in-hospital and postdischarge rate of any stroke, death, cardiac event (new Q-wave myocardial infarction or cardiac arrest), and combined stroke/death and combined adverse outcome (S/D/CE) at 30 days following CEA. Multivariable analyses were used to identify predictors for in-hospital and postdischarge events separately, and in particular, those that predict postdischarge events distinctly. RESULTS A total of 35,916 patients who underwent CEA during 2005-2010 were identified in the National Surgical Quality Improvement Program database; 59% were male, median age was 72 years, and 44% had a previous neurologic event. Thirty-day stroke rate was 1.6% (n = 591), death rate was 0.8% (n = 272), cardiac event rate was 1.0% (n = 350), stroke or death rate was 2.2% (n = 794), and combined S/D/CE rate was 2.9% (n = 1043); 33% of strokes, 53% of deaths, 32% of cardiac events, 40% of combined stroke/death, and 38% of combined S/D/CE took place after hospital discharge. Patients with a prior stroke or transient ischemic attack had similar proportions of postdischarge events compared with patients without prior symptoms. Independent predictors for postdischarge events, but not for in-hospital events were female sex (stroke [odds ratio (OR), 1.6; 95% confidence interval (CI), 1.2-2.1] and stroke/death [OR, 1.4; 95% CI, 1.1-1.7]), renal failure (stroke [OR, 3.0; 95% CI, 1.4-6.2]) and chronic obstructive pulmonary disease (death [OR, 2.5; 95% CI, 1.6-3.7], stroke/death [OR, 1.8; 95% CI, 1.4-2.4], and S/D/CE [OR 1.8, 95% CI 1.4-2.3]). CONCLUSIONS With 38% of perioperative adverse events after CEA happening posthospitalization, regardless of symptoms status, we need to be alert to the ongoing risks after discharge particularly in women, patients with renal failure, or chronic obstructive pulmonary disease. This emphasizes the need for reporting and comparing 30-day adverse event rates when evaluating outcomes for CEA, or comparing carotid stenting to CEA.

Abstract
OBJECTIVES To evaluate early and late results of carotid endarterectomy (CEA) in female patients in a large single center experience. METHODS Over a 12-year period ending in December 2007, 4009 consecutive primary and secondary CEAs in 3324 patients were performed at our institution. All patients were prospectively enrolled in a dedicated database containing pre-, intra-, and postoperative parameters. Patients were female in 1200 cases (1020 patients; Group 1) and male in the remaining 2809 (2304 patients, Group 2). Early results in terms of intraoperative neurological events and 30-day stroke and death rates were analyzed and compared. Follow-up results were analyzed with Kaplan Meier curves and compared with log-rank test. RESULTS Patients of Group 1 were more likely to have hyperlipemia, diabetes, and hypertension; patients of Group 2 were more likely to be smokers and to have concomitant coronary artery disease (CAD) and peripheral arterial disease (PAD). There were no differences in terms of clinical status or degree of stenosis. Patients of Group 2 had a significantly higher percentage of contralateral carotid artery occlusion than patients in Group 1 (6.9% and 3.9%, respectively; P < .001). Thirty-day stroke and death rates were similar in the two groups (1.2% for both groups). Univariate analysis demonstrated the presence of CAD, PAD, diabetes, and contralateral carotid artery occlusion to significantly affect 30-day stroke and death rate in female patients. At multivariate analysis, only diabetes (odds ratio [OR] 3.6, 95% confidence interval [CI] 0.1-0.9; P = .05) and contralateral occlusion (OR 7.4, 95% CI 0.03-0.6; P = .006) were independently associated with an increased perioperative risk of stroke and death. Median duration of follow-up was 27 months (range, 1-144 months). There were no overall differences between the two groups in terms of survival, freedom from ipsilateral stroke, freedom from any neurological symptom, and incidence of severe (>70%) restenosis. In contrast to male patients, univariate and multivariate analysis demonstrated that female patients with diabetes or contralateral occlusion had an increased risk of developing ipsilateral neurological events during follow-up. CONCLUSIONS Female sex per se does not represent an adjunctive risk factor during CEA, with early and long term results comparable to those obtained in male patients. However, in our study we found subgroups of female patients at higher surgical risk, requiring careful intra- and postoperative management.

Abstract
Introduction To determine if gender influences clinical outcomes and durability of repair after carotid angioplasty with stenting (CAS) or carotid endartercetomy (CEA), an analysis of patient records was performed. Methods This study included 89 CAS patients (47 men and 42 women) and 93 CEA patients (53 men and 40 women). Patients underwent duplex scans 6, 12, 24 months postprocedure. The outcomes of periprocedural mortality, major adverse events, strokes, and myocardial infarctions were assessed. Incidence of critical restenosis and recurrence of symptoms was also assessed. Results No significant differences were noted between men and women who had undergone either CAS or CEA ( P > .05) for clinical outcomes and durability of repair. No differences for periprocedural mortality, major adverse events, critical restenosis, recurrent neurologic symptoms, and adverse event free survival were found. Conclusions These results do not indicate substantial gender influences on clinical outcomes or durability of repair following CAS and CEA.

Abstract
BACKGROUND The role of carotid endarterectomy (CEA) for asymptomatic carotid artery stenosis (aCAS) remains a matter of debate. It seems that not only the degree of stenosis, but also other factors have to be taken in account to improve patient selection and increase the benefit of CEA for aCAS. METHODS AND RESULTS The literature pertaining aCAS was reviewed in order to describe the natural history, risk of stroke and benefit of CEA for patients with aCAS in regard to several factors. CONCLUSION The benefit of CEA for aCAS is low. Current factors influencing the indication for CEA are severity of stenosis, age, contralateral disease, stenosis progression to >80%, gender, concomitant operations and life expectancy. To improve patient selection investigations will concentrate on plaque characteristics and instability and cerebral hemodynamics and metabolism.

Abstract
Several studies have suggested that the benefits of CEA may be gender-dependent. The purpose of this study was to focus on age and gender outcomes after CEA. Three hundred seventy-two CEAs were performed in 344 patients (115 females, 229 males; mean age 72.9 years). Mean follow-up was 25.8 months. Data were collected retrospectively by chart review, and follow-up data were obtained by clinical examination and duplex ultrasound. Recurrent stenosis was defined as >50% and/or occlusion. Three hundred and seventy-two CEAs were performed in 120 female and 252 male carotid arteries: 97.3% of patients underwent patch angioplasty (bovine pericardium 71.5%, Dacron 21.8%, vein 3.8%, and polytetrafluoroethylene 0.3%) and 2.7% of patients underwent eversion endarterectomy. Perioperative mortality rate (30-day) was 0.8% (0% of females vs. 1.2% of males), and stroke rate was 0.5% (1.7% of females vs. 0% of males), with no significant gender difference (p = 0.554 and p = 0.103, respectively). Follow-up ultrasound revealed 21 (7%) restenoses (>50%) and/or occlusions, with a significantly higher rate of restenosis in females (14% vs. 3.9% in males, p = 0.008) and in patients <70 years of age at time of surgery (p = 0.003). There was no age difference between women and men with restenosis. Although there was no statistical difference in occurrence of restenosis between Dacron and bovine patch (p = 0.62), females who underwent patch angioplasty with Dacron were more likely to develop restenosis (p = 0.052). CEA is a low-risk procedure for significant carotid stenosis; however, females are more likely to develop restenosis after carotid surgery, especially with Dacron patches. Younger patients appear to be at a higher risk of restenosis after surgery.

Abstract
BACKGROUND Randomized trials of carotid endarterectomy (CEA) for both symptomatic and asymptomatic carotid stenosis have demonstrated that benefit is decreased in women, due partly to a high operative risk, which is independent of age. However, it is uncertain whether these trial-based observations are generalisable to routine clinical practice. METHODS We performed a systematic review of all publications reporting data on the association between age and/or sex and procedural risk of stroke and/or death following CEA from 1980 to 2004. RESULTS 62 eligible papers reported relevant data. Females had a higher rate of operative stroke and death (25 studies, OR = 1.31, 95% CI = 1.17-1.47, p < 0.001) than males, but no increase in operative mortality (15 studies, OR = 1.05, 95% CI = 0.81-0.86, p = 0.78). Compared with younger patients, operative mortality was increased at > or =75 years (20 studies, OR = 1.36, 95% CI = 1.07-1.68, p = 0.02), at age > or =80 years (15 studies, OR = 1.80, 95% CI = 1.26-2.45, p < 0.001) and in older patients overall (35 studies, OR = 1.50, 95% CI = 1.26-1.78, p < 0.001). In contrast, risk of non-fatal stroke did not increase with age and so the combined perioperative risk was only slightly increased at age > or =75 years (21 studies, OR = 1.18, 95% CI = 0.94-1.44, p = 0.06), at age > or =80 years (10 studies, OR = 1.14, 95% CI = 0.92-1.36, p = 0.34) and in older patients overall (36 studies, OR = 1.17, 95% CI = 1.04-1.31, p = 0.01). CONCLUSIONS The effects of age and sex on the operative risk of CEA in published case series are consistent with those observed in the trials. Operative risk of stroke is increased in women and operative mortality is increased in patients aged > or =75 years.

Abstract
BACKGROUND The incidence of adverse events after carotid endarterectomy (CEA) for women compared with men is controversial. This report compares the incidence of perioperative stroke and death in men and women by examining the effect of comorbidities and hospital setting on CEA outcomes. METHODS All CEAs performed in non-Federal acute-care Virginia hospitals between 1997 and 2001 were reviewed. Patient demographics, comorbidities, and hospital characteristics were compared for possible relationships to perioperative adverse events. RESULTS A total of 14,095 CEAs were performed in 34 urban and 28 rural hospitals (9 high-volume and 53 low-volume hospitals); 42% were performed on women, and 58% were performed on men. Women experienced a significantly higher stroke rate (1.23%) than men (0.87%; P = .04) with bivariate analysis. However, logistic regression analysis of comorbidities and hospital settings demonstrated that sex was actually not independently related to adverse outcomes in CEA ( P = .08). Preoperative neurologic symptoms could not be evaluated as risk factors for adverse events. Acute coronary ischemia, history of arrhythmia, end-stage renal disease, nonwhite race, advanced age, and low hospital volume were all significantly related to mortality. History of arrhythmia was the only factor that was significantly related to the incidence of stroke. CONCLUSIONS Logistic regression analysis of comorbidities and hospital setting indicated that female sex is not independently associated with higher mortality or a higher stroke rate during CEA. These data indicate that patients with carotid stenosis frequently have multiple medical problems that need to be carefully examined and controlled before any single patient or hospital factor is designated as significantly related to adverse outcomes.

Abstract
BACKGROUND Studies that examined the rates of and mortality after carotid endarterectomy (CEA) mainly were confined to a limited geographical location or population. The primary purposes of this study are to examine the variation of risk-adjusted in-hospital mortality rates after CEA in 10 states, and utilization rates per capita of CEA. METHODS An analysis was made of hospital discharge data from 10 states extracted from the Agency for Health Research and Quality national database, Healthcare Cost and Utilization Project (HCUP). RESULTS The rates of CEA per capita were found to differ among the 10 states examined. No significant association was detected between geographic location and the adjusted risk of in-hospital mortality. Sex, age, type of admission, and several comorbidities were found to be significant risk factors. CONCLUSIONS Rates of CEA per capita differ among states. However, geographical location does not affect the likelihood of risk-adjusted mortality after the procedure.

Abstract
BACKGROUND The mean age of patients in the European Carotid Surgery Trial with greater than 70% stenosis was 62 years. With changing demographics older patients are increasingly being referred for carotid endarterectomy (CEA). OBJECTIVES To assess the complications and survival (stroke-free and overall) of patients over the age of 75 undergoing CEA. METHODS Analysis of a database, clinical records and cause of death of patients undergoing CEA in a single regional unit over a 7 year period (1/4/1993 until 1/4/2000), with follow-up to April 2002. The rates of further neurological events were obtained from the Scottish Morbidity Record 1 (SMR 1) of hospital discharges. Patients referred from outside the region were excluded. Differences between groups were assessed by the Chi-squared test, with Yates correction and log-rank tests. RESULTS Of the 235 patients undergoing CEAs, 55 (23%) were 75 years or older. The post-operative neurological complication rate was 1.7% in the under 75's and 5.4% in the older group (p < 0.05). The 30 day mortality was 1.1% (two patients) and 1.8% (one patient) respectively. The Kaplan-Meier estimated survival for the under 75's and older were 93 and 75% at 3 years and 80 and 59% at 5 years respectively (p < 0.001). The Kaplan-Meier estimated neurological event-free 5 year survival for the under 75's and older patients were 96 and 82% respectively (p < 0.001). CONCLUSION CEA in patients aged 75 years and over is associated with a significantly increased risk of stroke and death. CEA may not benefit elderly patients with a reduced life expectancy.

Abstract
BACKGROUND AND PURPOSE The existing literature provides conflicting evidence on surgical risks of carotid endarterectomy in women compared with men. We used data from a large population-based carotid surgery registry to determine whether sex differences exist in the risk of perioperative complications from carotid endarterectomy. METHODS We analyzed data from the Ontario Carotid Endarterectomy Registry, which contains data on all patients who underwent carotid endarterectomy in the province of Ontario between 1994 and 1997. We compared the risk of death or stroke at 30 days in women and men and used multivariate analyses to adjust for age, comorbid conditions, and surgical factors. Secondary analyses compared the risks of death and/or stroke in women and men at 2 years after surgery. RESULTS The study sample consisted of 6038 patients (35% women). The risks of perioperative stroke or death were not significantly different in women compared with men (adjusted hazard ratio, 1.10; 95% CI, 0.90 to 1.35). The combined risk of stroke or death at 2 years after surgery was also similar in women and men (adjusted hazard ratio, 1.05; 95% CI, 0.92 to 1.21). However, women were more likely to have a stroke (adjusted hazard ratio, 1.26; 95% CI, 1.05 to 1.51) and less likely to die (adjusted hazard ratio, 0.82; 95% CI, 0.68 to 0.99) within 2 years after surgery. CONCLUSIONS Perioperative complication rates from carotid endarterectomy are similar in women and men. Women should not be discouraged from carotid endarterectomy solely on the basis of surgical risks.

Abstract
OBJECTIVE Post hoc analysis results of the North American Symptomatic Carotid Endarterectomy Trial and the Asymptomatic Carotid Atherosclerosis Study suggest that carotid endarterectomy (CEA) may not be as efficacious in women as it is in men. This study was undertaken for the evaluation of whether there is a difference between men and women in early postoperative outcome after CEA and whether such a difference is consistent across other predictors. METHODS We conducted a retrospective review of all CEAs entered into our departmental registry between January 1, 1989, and November 30, 2000. A total of 3422 CEAs was performed in 3077 consecutive patients. The ratio of men to women was 2:1, and the ratio of patients who were asymptomatic to patients who were symptomatic was 2.3:1. The following in-hospital outcome data were analyzed: transient ischemic attack (TIA), stroke, mortality, combined TIA or stroke, and combined stroke or mortality. Univariate and multivariate analysis results of selected risk factors for an adverse perioperative event were assessed with generalized estimating equation analysis with backwards selection. The following risk factors were considered: gender, preoperative neurologic status, urgency of operation, type of arteriotomy repair, reoperative CEA for recurrent stenosis, history of cardiopulmonary disease, previous coronary artery intervention, simultaneous CEA and coronary bypass grafting surgery, renal failure, and diabetes. RESULTS Univariate analysis results of gender differences revealed that women were at higher risk for a postoperative TIA or stroke (3.3% for women versus 2.1% for men; odds ratio [OR], 1.6; confidence interval [CI], 1.04 to 2.5; P =.03) and for postoperative stroke or mortality (3.1% for women versus 2.1% for men; OR, 1.6; CI, 1.04 to 2.5; P =.03). Multivariate analysis results showed that female gender was an independent predictor for a postoperative TIA or stroke (OR, 1.7; CI, 1.1 to 2.6; P =.03). Further analysis disclosed that women who were asymptomatic were at greater risk than were men for postoperative stroke or mortality (OR, 2.3; CI, 1.3 to 3.9; P =.003). Conversely, there was no gender association for postoperative stroke or mortality in the consideration of only patients who were symptomatic (OR, 1.0; CI, 0.45 to 2.1; P =.95). The interaction between women and preoperative symptoms approached significance (P =.07) with respect to postoperative stroke and mortality rate, which suggests that the gender effect could be influenced by the clinical presentation. CONCLUSION The combined TIA or stroke and stroke or mortality rates are higher in women as compared with men in the postoperative period, but these risks remain acceptable when CEA is performed for appropriate indications. The interaction between symptoms and gender suggests that, in patients who are asymptomatic, women are more likely than are men to have early complications. However, there is no gender difference in patients who are symptomatic. Therefore, despite a low postoperative complication rate, CEA is appropriate in both women who are asymptomatic and women who are symptomatic only if the postoperative TIA, stroke, and mortality rates are appreciably lower than in the natural history of medical management of these patients.

Abstract
Many surgeons use a vein-patch angioplasty after endarterectomy of small (< 4 mm) diameter carotid arteries in males and females. Because evidence suggests that females may have a poorer outcome than males after revascularization, the long-term success of carotid endarterectomy may be different among the genders. The 10-year outcome after a saphenous vein-patch angioplasty in females was studied. Endarterectomies were performed on 708 carotid arteries of 615 patients, who had evidence of symptomatic disease or had asymptomatic greater than 80% stenosis. A segment of proximal greater saphenous vein was harvested for the patch. The 247 females had a mean age of 69.1 +/-9.8 (SD) years and a follow-up time of 4.0 +/-4.0 (SD) years. The 368 males had a mean age of 69.2 +/-8.8 (SD) years and a follow-up time of 4.4 +/-4.0 (SD) years. After endarterectomy, survival, the ipsilateral stroke-free rates and the restenosis-free rates were determined by life table analyses with 73 endarterectomies in 66 patients being at risk at 10 years. The 5- and 10-year survival rates in males were 81.9% and 62.2%, respectively. The 5- and 10-year survival rates in females were 82.6% and 73.0%, respectively. The 5- and 10-year ipsilateral stroke-free rates after carotid endarterectomy were 98.3% and 93.9% in males and 96.7% and 95.6% in females. The respective 5- and 10-year restenosis-free rates were 96.7% and 93.3% in males and 88.6% and 82.8% in females; p < 0.0002, by the Mantel-Cox test. Although survival and the incidence of an ipsilateral stroke were similar in females and males, the hemodynamic restenosis rate was higher in females. It is especially important to use routine duplex scanning to follow the post-endarterectomy health of the carotid artery in females.

Abstract
PURPOSE Carotid endarterectomy (CEA) effectively reduces stroke risk in properly selected patients. Subgroup analysis of the Asymptomatic Carotid Artery Study trial noted increased complications in women. Additional studies implicate female gender as a risk factor for perioperative stroke, leading some clinicians to modify the indications for CEA in women. The purpose of this study was to determine the influence of gender on the risk of perioperative complications in patients undergoing CEA. METHODS The records of all patients who underwent CEA at a university medical center from January 1995 to December 1999 were reviewed. Patient demographics, procedure related risk factors, operative details, and specific complications were entered into a database for statistical analysis. RESULTS A total of 324 consecutive patients underwent CEA during the study period. There were 199 men (61%) and 125 women (39%). Among the men and women, there were no differences in age, smoking, hypertension, hypercholesterolemia, diabetes, family history, renal insufficiency, or symptomatic versus asymptomatic indications for CEA. More women than men received a carotid patch (90.4% versus 77.9%, P = 0.003). One woman died (0.8%) and no men died for a total combined 30-day mortality of 0.31% (P = not significant). Men and women did not differ in rates of stroke (1.5% versus 2.4%) or perioperative myocardial infarction (1.0% versus 0.8%). In addition, there was no difference when stroke and death rates were combined (2% versus 3.2%). The length of stay (2.2 versus 2.6 days) was also not different. CONCLUSIONS There are no significant differences in rate of stroke, myocardial infarction, or 30-day mortality, between men and women following CEA. Women should not be excluded from the benefits of CEA based on perceived increased complication rates.

Abstract
OBJECTIVE To evaluate and compare the short- and long-term outcomes in female and male patients after carotid endarterectomy (CEA). SUMMARY BACKGROUND DATA Randomized carotid trials have clearly shown the benefits of CEA in specific symptomatic and asymptomatic patients. However, the short- and long-term benefits in women appear to be less clear, and the role of CEA among women with carotid disease remains uncertain. METHODS During a 21-year period, 1,204 CEAs were performed, 464 (39%) in women and 739 (61%) in men. Complete follow-up was available in 70% of patients. RESULTS Women were less likely to have evidence of coronary artery disease, were more likely to be hypertensive, and had a significantly greater incidence of diabetes. The mean age at CEA was 68.5 +/- 9.5 years for women and 68.0 +/- 8.5 years for men. There were no significant differences in the use of shunts, patching, tacking sutures, or severity of carotid stenoses between men and women. Surgical death rates were nearly identical for asymptomatic and symptomatic patients. Perioperative stroke rates were similar for asymptomatic and symptomatic patients. Life-table stroke-free rates at 1, 5, and 8 years were similar for asymptomatic women and men and symptomatic women and men. Long-term survival rates at 1, 5, and 8 years were higher for asymptomatic women compared with men and for symptomatic women compared with men. As a result, stroke-free survival rates at these follow-up intervals were greater for asymptomatic women compared with men, and for symptomatic women compared to men. CONCLUSIONS The results from this study challenge the conclusions from the Asymptomatic Carotid Endarterectomy Study and the North American Symptomatic Carotid Endarterectomy Trial regarding the benefits of CEA in women. Female gender did not adversely affect early or late survival, stroke-free, or stroke-free death rates after CEA. The authors conclude that CEA can be performed safely in women with asymptomatic and symptomatic carotid artery disease, and physicians should expect comparable benefits and outcomes in women and men undergoing CEA.

Abstract
OBJECTIVES Although the results of the Asymptomatic Carotid Atherosclerosis Study clearly demonstrated the benefit of surgical over medical management of severe carotid artery stenosis, the results for women in particular were less certain. This was to some extent because of the higher perioperative complication rate observed in the 281 women (3.6% vs 1.7% in men). The objective of this study was to review a large experience with carotid endarterectomy in female patients and to determine whether the perioperative results differed from those of male patients. METHODS A review was conducted of a prospectively compiled database on all carotid endarterectomies performed between 1982 and 1997. Operations performed in 991 female patients were compared with those performed in 1485 male patients. RESULTS Female patients had a significantly lower incidence of diabetes, coronary artery disease, and contralateral carotid artery occlusion than did male patients. Female patients had a significantly higher incidence of hypertension. There were no significant differences in the age, smoking history, anesthetic route, shunt use, or clamp tolerance between the two groups. Of 991 female patients, 659 (66.5%) had preoperative symptoms, whereas 332 (33.5%) cases were performed for asymptomatic stenosis. Among 1485 male patients, 1041 (70.1%) had symptoms, and 444 (29.9%) were symptom free before surgery. There were no significant differences noted in the perioperative stroke rates between men and women overall (2.3% vs 2.4%, P =.92), or when divided into symptomatic (2.5% vs 3.0%, P =.52) and asymptomatic (2.0% vs 1.2%, P =.55) cases. CONCLUSIONS Carotid endarterectomy can be performed with equally low perioperative stroke rates in men and women in both symptomatic and asymptomatic cases. In this series, symptom-free female patients had the lowest overall stroke rate. The concerns of the Asymptomatic Carotid Atherosclerosis Study regarding the benefit of carotid endarterectomy in female patients should therefore not prevent clinicians from recommending and performing carotid endarterectomy in appropriately selected symptom-free female patients.
