Project description:ObjectiveCarotid endarterectomy (CEA) with concomitant distal endovascular intervention (CEA+D) is infrequently necessary but has often been used as a salvage maneuver when complications occur during CEA. The present study aimed to determine whether preoperative risk factors associated with CEA requiring CEA+D exist and to evaluate the outcomes compared with isolated CEA.MethodsThe Vascular Quality Initiative CEA registry was used to identify patients who had undergone CEA or CEA+D for asymptomatic or symptomatic carotid stenosis from 2013 to 2019. Data regarding distal intervention included whether angioplasty or stenting of the distal internal carotid artery (ICA) and/or bifurcation had been required. However, information regarding the indication or whether the intervention had been planned was not included. The χ2 test and analysis of variance were used to evaluate the categorical and continuous perioperative variables. Variables with P < .20 on univariate analysis were included in the multivariable analysis to assess for preoperative predictors of the need for CEA+D and the association with perioperative stroke.ResultsFrom 2013 to 2019, 327 CEA+D cases were identified and compared with 105,192 isolated CEA cases. The CEA+D patients were more likely to have undergone previous ipsilateral CEA (CEA, 1.8%; CEA+D, 4.9%; P < .01) and contralateral ICA occlusion (CEA, 4.6%; CEA+D, 11.0%; P < .01) but were less likely to have had ipsilateral stenosis ≥70% (CEA, 88.3%; CEA+D, 80.6%; P < .01). The preoperative factors associated with the need for CEA+D on multivariable analysis included previous peripheral vascular intervention, American Society of Anesthesiologists class ≥4, contralateral ICA occlusion, low-volume surgeon, and previous ipsilateral CEA. CEA+D was associated with significantly increased rates of stroke in both asymptomatic (CEA+D, 3.9%; CEA, 0.9%; P < .01) and symptomatic (CEA+D, 9.4%; CEA, 1.9%; P < .01) patients. CEA+D was associated with decreased rates of 30-day survival in both asymptomatic (CEA+D, 98.3%; CEA, 99.4%; P = .02) and symptomatic (CEA+D, 94.8%; CEA, 99.1%; P < .01) cohorts. On multivariable analysis, CEA+D remained significantly associated with stroke (odds ratio, 3.17; 95% confidence interval, 1.80-5.60; P < .01). Other factors significantly associated with perioperative stroke included procedure length >135 minutes, diabetes, hypertension, shunt for indication, symptomatic status, previous ipsilateral CEA, contralateral ICA occlusion, urgent or emergent procedure, intravenous medications for hemodynamic instability, and re-exploration at the initial operation.ConclusionsAlthough markers of more significant cardiovascular disease burden were associated with the use of CEA+D, their power to predict CEA+D use was limited. In cases in which CEA+D was used, CEA+D was associated with significantly greater rates of perioperative stroke and mortality compared with isolated CEA for both asymptomatic and symptomatic patients, which could be useful for framing the expected outcomes after these procedures.

Project description:Rapid identification of the type and origin of a stroke is crucial for prompt and appropriate treatment, which can significantly influences patient outcomes. We report a multidisciplinary management case involving a 76-year-old man who presented with left-sided weakness and mild dysarthria. Imaging revealed a completely occluded right internal carotid artery. Despite multiple endovascular recanalization attempts, adequate flow could not be achieved, leading to the decision to perform an open thrombo-endarterectomy. The patient underwent carotid endarterectomy with microsurgical techniques under general anesthesia. The atheroma plaque and central thrombus were removed, which reestablished flow. Continuous intraoperative neuromonitoring was utilized to ensure patient safety. The patient woke up without new deficits and was discharged for rehabilitation. Follow-up imaging confirmed arterial patency, and the patient eventually made an excellent recovery, including being independent over one and a half years. Emergent recanalization with carotid endarterectomy following a failed endovascular recanalization is both safe and feasible, emphasizing the need for collaboration between different treatment providers to ensure optimal patient outcomes. Our report highlights the importance of a multidisciplinary approach and the advantages of a hybrid operating room in the treatment of acute complete carotid artery occlusion.

Project description:BackgroundStroke/death rates within 30 days of carotid endarterectomy (CEA) and carotid artery stenting (CAS) in RCTs inform current clinical guidelines. However, the risks may have changed in recent years with wider use of effective stroke prevention therapies, especially statins, improved patient selection and growing operator expertise. The aim of this study was to investigate whether the procedural stroke/death risks from CEA and CAS have changed over time.MethodsMEDLINE and Embase were searched systematically from inception to May 2016 for observational cohort studies of CEA and CAS. Studies included reported on more than 1000 patients, with 30-day outcomes after the procedure according to patients' symptom status (recent stroke or transient ischaemic attack). Restricted maximum likelihood random-effects and meta-regressions methods were used to synthesize procedural stroke/death rates of CEA and CAS according to year of study recruitment completion.ResultsFifty-one studies, including 223 313 patients undergoing CEA and 72 961 undergoing CAS, were reviewed. Procedural stroke/death risks of CEA decreased over time in symptomatic and asymptomatic patients. Risks were substantially lower in studies completing recruitment in 2005 or later, both in symptomatic (5·11 per cent before 2005 versus 2·68 per cent from 2005 onwards; P = 0·002) and asymptomatic (3·17 versus 1·50 per cent; P < 0·001) patients. Procedural stroke/death rates of CAS did not change significantly over time (4·77 per cent among symptomatic and 2·59 per cent among asymptomatic patients). There was substantial heterogeneity in event rates and recruitment periods were long.ConclusionsRisks of procedural stroke/death following CEA appear to have decreased substantially. There was no evidence of a change in stroke/death rates following CAS.

Project description:Background The goal of this study was to create a comprehensive, integer-weighted predictive scale of adverse events after carotid endarterectomy (CEA), which may augment risk stratification and patient counseling. Methods and Results The targeted carotid files from the prospective NSQIP (National Surgical Quality Improvement Program) registry (2011-2013) comprised the derivation population. Multivariable logistic regression evaluated predictors of a 30-day adverse event (stroke, myocardial infarction, or death), the effect estimates of which were used to build a weighted predictive scale that was validated using the 2014 to 2015 NSQIP registry release. A total of 10 766 and 8002 patients were included in the derivation and the validation populations, in whom 4.0% and 3.7% developed an adverse event, respectively. The NSQIP registry CEA scale included 14 variables; the highest points were allocated for insulin-dependent diabetes mellitus, high-risk cardiac physiological characteristics, admission source other than home, an emergent operation, American Society of Anesthesiologists' classification IV to V, modified Rankin Scale score ≥2, and presentation with a stroke. NSQIP registry CEA score was predictive of an adverse event (concordance=0.67), stroke or death (concordance=0.69), mortality (concordance=0.76), an extended hospitalization (concordance=0.73), and a nonroutine discharge (concordance=0.83) in the validation population, as well as among symptomatic and asymptomatic subgroups (P<0.001). In the validation population, patients with an NSQIP registry CEA scale score >8 and 17 had 30-day stroke or death rates >3% and 6%, the recommended thresholds for asymptomatic and symptomatic patients, respectively. Conclusions The NSQIP registry CEA scale predicts adverse outcomes after CEA and can risk stratify patients with both symptomatic and asymptomatic carotid stenosis using different thresholds for each population.

Project description:Post-endarterectomy pseudoaneurysms (PEPA) are a rare complication of carotid endarterectomy (CEA), but are associated with high morbidity risk. Therefore, once they are diagnosed, treatment is urgent to prevent possible complications such as rupture, embolisation, thrombosis, or airway and cranial nerve compression. In this video, the surgical procedure is shown in a case of PEPA 10 years after CEA with patch angioplasty, which was successfully managed by surgical excision and interposition of great saphenous vein graft. Follow up duplex examination at six months was normal, with patency of the vein graft. This case reiterates the importance of open surgery as the treatment of choice for this difficult clinical setting.

Project description:BackgroundOver the past decades, stroke risk associated with carotid disease has decreased, reflecting improvements in medical therapy and a more rigorous control of vascular risk factors. It is less clear whether the procedural risk of carotid revascularization has declined over time.MethodsWe analyzed temporal changes in procedural risks among 4597 patients with symptomatic carotid stenosis treated with carotid artery stenting (n=2326) or carotid endarterectomy (n=2271) in 4 randomized trials between 2000 and 2008, using generalized linear mixed-effects models with a random intercept for each source trial. Models were additionally adjusted for age and other baseline characteristics predicting treatment risk. The primary outcome event was any procedural stroke or death, occurring during or within 30 days after revascularization.ResultsThe procedural stroke or death risk decreased significantly over time in all patients (unadjusted odds ratio per year, 0.91; 95% CI, 0.85-0.97; P=0.006). This effect was driven by a decrease in the carotid endarterectomy group (unadjusted odds ratio per year, 0.82; 95% CI, 0.73-0.92; P=0.003), whereas no significant decrease was found after carotid artery stenting (unadjusted odds ratio, 0.96; 95% CI, 0.88-1.04; P=0.33). Carotid endarterectomy patients had a lower procedural stroke or death risk compared with carotid artery stenting patients, and the difference significantly increased over time (interaction P=0.031). After adjustment for baseline characteristics, the results remained essentially the same.ConclusionsThe risk of stroke or death associated with carotid endarterectomy for symptomatic carotid stenosis decreased over an 8-year period, independent of clinical predictors of procedural risk. No corresponding reduction in procedural risk was seen in patients treated with stenting.Clinical trial registrationURL: https://www.clinicaltrials.gov; http://www.isrctn.com.

Project description:BackgroundStroke occurs more commonly after carotid artery stenting than after carotid endarterectomy. Details regarding stroke type, severity, and characteristics have not been reported previously. We describe the strokes that have occurred in the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST).Methods and resultsCREST is a randomized, open-allocation, controlled trial with blinded end-point adjudication. Stroke was a component of the primary composite outcome. Patients who received their assigned treatment within 30 days of randomization were included. Stroke was adjudicated by a panel of board-certified vascular neurologists with secondary central review of clinically obtained brain images. Stroke type, laterality, timing, and outcome were reported. A periprocedural stroke occurred among 81 of the 2502 patients randomized and among 69 of the 2272 in the present analysis. Strokes were predominantly minor (81%, n=56), ischemic (90%, n=62), in the anterior circulation (94%, n=65), and ipsilateral to the treated artery (88%, n=61). There were 7 hemorrhages, which occurred 3 to 21 days after the procedure, and 5 were fatal. Major stroke occurred in 13 (0.6%) of the 2272 patients. The estimated 4-year mortality after stroke was 21.1% compared with 11.6% for those without stroke. The adjusted risk of death at 4 years was higher after periprocedural stroke (hazard ratio, 2.78; 95% confidence interval, 1.63-4.76).ConclusionsStroke, particularly severe stroke, was uncommon after carotid intervention in CREST, but stroke was associated with significant morbidity and was independently associated with a nearly 3-fold increased future mortality. The delayed timing of major and hemorrhagic stroke after revascularization suggests that these strokes may be preventable.

Project description:Background and Purpose- Patients undergoing surgery on the weekend may experience worse outcomes, but this weekend effect has not been studied in carotid endarterectomy (CEA). Methods- We identified patients undergoing isolated CEA in the Vascular Quality Initiative between 2003 and 2018. Our primary outcome was in-hospital stroke or perioperative death (stroke/death), stratified by symptom status. For asymptomatic patients, we also compared rates of the Centers for Medicare and Medicaid Services quality metric prolonged length of stay (>2 days or failed discharge home). We calculated propensity scores and used multilevel, inverse probability weighted logistic regression clustering at the hospital level. Results- There were 86 123 repairs during the study period, 53% asymptomatic lesions and 47% symptomatic. Only 0.7% of asymptomatic patients underwent CEA on the weekend, compared with 3.1% of symptomatic patients. Patients undergoing weekend repairs were more often white, with lower rates of most comorbidities. In asymptomatic patients, weekend operations were associated significantly higher odds of stroke/death (odds ratio [OR], 2.3 [1.1-4.8]; P=0.02), and prolonged length of stay (OR, 3.6 [2.7-4.7]; P<0.001). In symptomatic patients, weekend operations were associated with significantly higher adjusted odds of stroke/death (OR, 1.7 [1.2-2.4]; P=0.007) and longer postoperative length of stay (3.3 days versus 2.0 days, P=0.002). However, the difference in stroke/death was driven by patients presenting with stroke (OR, 2.2 [1.5-2.3]; P<0.001), rather than those presenting with transient ischemic attack (OR, 1.2 [0.6-2.1]; P=0.56). Conclusions- We found evidence of a significant weekend effect in CEA, as weekend operations in asymptomatic patients and patients who presented with stroke were associated with higher rates of stroke/death and prolonged length of stay. However, there was no evidence of such an effect in patients with transient ischemic attack. These data suggest that weekend CEA should be avoided except in the case of expedited revascularization after transient ischemic attack.

Project description:BackgroundThe Carotid Revascularization Endarterectomy Versus Stenting Trial (CREST) found a higher risk of stroke after carotid artery stenting and a higher risk of myocardial infarction (MI) after carotid endarterectomy.Methods and resultsCardiac biomarkers and ECGs were performed before and 6 to 8 hours after either procedure and if there was clinical evidence of ischemia. In CREST, MI was defined as biomarker elevation plus either chest pain or ECG evidence of ischemia. An additional category of biomarker elevation with neither chest pain nor ECG abnormality was prespecified (biomarker+ only). Crude mortality and risk-adjusted mortality for MI and biomarker+ only were assessed during follow-up. Among 2502 patients, 14 MIs occurred in carotid artery stenting and 28 MIs in carotid endarterectomy (hazard ratio, 0.50; 95% confidence interval, 0.26 to 0.94; P=0.032) with a median biomarker ratio of 40 times the upper limit of normal. An additional 8 carotid artery stenting and 12 carotid endarterectomy patients had biomarker+ only (hazard ratio, 0.66; 95% confidence interval, 0.27 to 1.61; P=0.36), and their median biomarker ratio was 14 times the upper limit of normal. Compared with patients without biomarker elevation, mortality was higher over 4 years for those with MI (hazard ratio, 3.40; 95% confidence interval, 1.67 to 6.92) or biomarker+ only (hazard ratio, 3.57; 95% confidence interval, 1.46 to 8.68). After adjustment for baseline risk factors, both MI and biomarker+ only remained independently associated with increased mortality.ConclusionsIn patients randomized to carotid endarterectomy versus carotid artery stenting, both MI and biomarker+ only were more common with carotid endarterectomy. Although the levels of biomarker elevation were modest, both events were independently associated with increased future mortality and remain an important consideration in choosing the mode of carotid revascularization or medical therapy.Clinical trial registrationURL: http://www.ClinicalTrials.gov.

Project description:ObjectivesThe purpose of this study was to compare health-related quality of life (HRQOL) outcomes in patients treated with carotid artery stenting (CAS) versus carotid endarterectomy (CEA).BackgroundIn CREST (Carotid Revascularization Endarterectomy versus Stenting Trial), the largest randomized trial of carotid revascularization to date, there was no significant difference in the primary composite endpoint, but rates of stroke and myocardial infarction (MI) differed between CAS and CEA. To help guide individualized clinical decision making, we compared HRQOL among patients enrolled in the CREST study. We also performed exploratory analyses to evaluate the association between periprocedural complications and HRQOL.MethodsWe measured HRQOL at baseline, and after 2 weeks, 1 month, and 1 year among 2,502 patients randomly assigned to either CAS or CEA in the CREST study. The HRQOL was assessed using the Medical Outcomes Study Short-Form 36 (SF-36) and 6 disease-specific scales designed to study HRQOL in patients undergoing carotid revascularization.ResultsAt both 2 weeks and 1 month, CAS patients had better outcomes for multiple components of the SF-36, with large differences for role physical function, pain, and the physical component summary scale (all p < 0.01). On the disease-specific scales, CAS patients reported less difficulty with driving, eating/swallowing, neck pain, and headaches but more difficulty with walking and leg pain (all p < 0.05). However, by 1 year, there were no differences in any HRQOL measure between CAS and CEA. In the exploratory analyses, periprocedural stroke was associated with poorer 1-year HRQOL across all SF-36 domains, but periprocedural MI or cranial nerve palsy were not.ConclusionsAmong patients undergoing carotid revascularization, CAS is associated with better HRQOL during the early recovery period as compared with CEA-particularly with regard to physical limitations and pain-but these differences diminish over time and are not evident after 1 year. Although CAS and CEA are associated with similar overall HRQOL at 1 year, event-specific analyses confirm that stroke has a greater and more sustained impact on HRQOL than MI.
