Abstract
Background There is currently no consensus regarding the optimal perioperative antiplatelet strategy for carotid artery surgery. This multicentre study aimed to analyse the association between preoperative aspirin monotherapy following postoperative dual antiplatelet therapy (DAPT) and the risk for stroke and death after carotid endarterectomy (CEA). Methods This cohort study included 821 patients with carotid artery stenosis who underwent CEA. Primary outcomes included any stroke or death up to the one-month postoperative follow-up. Multilevel multivariate regression analyses and descriptive statistics were performed. Results Patients were predominantly male (53 %), with a mean age of 66.2 years. The primary outcome occurred in 1.6 % of patients. Univariate and multivariate analyses revealed that patients with chronic obstructive pulmonary disease (COPD) exhibited a high risk for stroke or death (P = 0.011). The occurrence of any local complications in the neck was accompanied by an increase in diastolic blood pressure (DBP) (P = 0.007). Patients with a high systolic blood pressure (SBP) (P = 0.002) experienced a longer operative duration. The length of hospital stay was longer in the patients with COPD (P = 0.020), minor stroke (P = 0.011), and major stroke (P = 0.001). A positive linear correlation was found between SBP and operative duration in the overall population (β 0.4 [95 % confidence interval (CI) 0.1-0.7]; P = 0.002). The resultant curve for DBP and any local complications in the neck exhibited a two-stage change and one breakpoint in the entire population (k = 68 mmHg, <68; odds ratio [OR] 0.9 [95 % CI 0.7-1.1], P = 0.461; ≥68: OR 1.1 [95 % CI 1.0-1.1], P = 0.003). Conclusions Preoperative aspirin monotherapy and postoperative DAPT were safe and effective antiplatelet treatments for patients who underwent CEA.

Ann Vasc Surg 2022; 88:199-209. [PMID: 36116744 DOI: 10.1016/j.avsg.2022.08.018] [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: 06/08/2022] [Revised: 08/01/2022] [Accepted: 08/04/2022] [Indexed: 11/18/2022]
Abstract
OBJECTIVES A retrospective analysis of neck haematoma, stroke and mortality after symptomatic and asymptomatic carotid endarterectomy (CEA) was conducted, in order to determine the most appropriate perioperative medication for these patients. Thirty-day outcomes of moderate and severe neck bleeding were also investigated. METHODS Patients undergoing CEA in a Vascular Surgery department were analysed (2015-2019). Pre-procedure antithrombotic medication (from the 5-days prior to surgery) was identified. End point predictors were identified by univariate and multivariable analyses and adjusted for confounders. RESULTS A total of 304 CEA were included. Almost half of the included patients (49.67%) were under low-dose aspirin, 17.55% other single antiplatelet agent, 12.59% dual antiplatelet therapy, 8.61% anticoagulation and 10.92% no antithrombotic therapy. There was 8.22% rate of important haematoma, including 4.93% severe (requiring surgical exploration) hematomas and a 30-day all-stroke incidence of 2.94% in symptomatic and 1.79% asymptomatic patients (p=.51). When compared to aspirin, severe haematoma was more prevalent with single clopidogrel or triflusal (RR 4.25, p=.11), dual antiplatelet group (RR 11.84, p=.002) and anticoagulation (RR 8.604, p=.02). Dual antiaggregation and anticoagulation did not confer post-operative stroke protection compared to single aspirin in either symptomatic or asymptomatic patients. Non-significant higher intra-hospital mortality was noted in no medication, dual antiplatelet and anticoagulation groups in contrast to aspirin. Severe neck bleeding was associated with increased congestive heart failure (9.26-fold, p=.03) and longer hospital stay (11.20±24.69 days versus 3.18±4.79 with no bleeding, p<.001), with a tendency for higher hospital readmission at 30-days (4.66-fold, p=.13). Mortality and stroke rates were similar. CONCLUSIONS Double antiaggregation and anticoagulation did not confer better perioperative outcomes after elective CEA in our study. These regimens were associated with increased risk of neck haematoma, especially severe bleeding, with similar rates of neurologic events in both symptomatic and asymptomatic patients and no mortality benefit. Monotherapy with aspirin appears to be the safest perioperative antithrombotic regimen for elective CEA.

Eur J Vasc Endovasc Surg 2022; 63:546-555. [PMID: 35241374 DOI: 10.1016/j.ejvs.2021.12.037] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Revised: 12/01/2021] [Accepted: 12/28/2021] [Indexed: 12/27/2022]
Abstract
OBJECTIVE A systematic review and meta-analysis of the peri-operative outcomes of carotid endarterectomy (CEA) on dual antiplatelet therapy (DAPT) vs. aspirin monotherapy was carried out, to determine optimal peri-operative management with these antiplatelet agents. DATA SOURCES The Web of Science, Pubmed, and Embase databases were searched from inception to July 2021. The corresponding authors of excluded articles were contacted to obtain additional data for possible inclusion. REVIEW METHODS The main outcomes included ischaemic complications (stroke, transient ischaemic attack [TIA], and transcranial Doppler [TCD] measured micro-emboli), haemorrhagic complications (haemorrhagic stroke, neck haematoma, and re-operation for bleeding), and composite outcomes. Pooled estimates using odds ratios (ORs) were combined using a random or fixed effects model based on the results of the chi square test and calculation of I2. RESULTS In total, 47 411 patients were included in 11 studies, with 14 345 (30.2%) receiving DAPT and 33 066 (69.7%) receiving aspirin only. There was no significant difference in the rates of peri-operative stroke (OR 0.87, 95% confidence interval [CI] 0.72 - 1.05) and TIA (OR 0.78, 95% CI 0.52 - 1.17) despite a significant reduction in TCD measured micro-emboli (OR 0.19, 95% CI 0.10 - 0.35) in the DAPT compared with the aspirin monotherapy group. Subgroup analysis did not reveal any significant difference in ischaemic stroke risk between patients with asymptomatic and symptomatic carotid artery stenosis. DAPT was associated with an increased risk of neck haematoma (OR 2.79, 95% CI 1.87 - 4.18) and re-operation for bleeding (OR 1.98, 95% CI 1.77 - 2.23) vs. aspirin. Haemorrhagic stroke was an under reported outcome in the literature. CONCLUSION This meta-analysis found that CEA while on DAPT increased the risk of haemorrhagic complications, with similar rates of ischaemic complications, vs. aspirin monotherapy. This suggests that the risks of performing CEA on DAPT outweigh the benefits, even in patients with symptomatic carotid stenosis. The overall quality of studies was low, and improved reporting of CEA outcomes in the literature is necessary.

Abstract
BACKGROUND Dual and single antiplatelet therapies are routinely used in carotid artery endarterectomy (CEA). However, the efficacy and safety of these therapies are controversial. The present study aimed to comprehensively compare the clinical outcomes between dual and single antiplatelet therapies in CEA. METHODS This study retrieved available academic studies evaluating the complications related to antiplatelet therapy between dual and single antiplatelet therapies in CEA from the databases of ScienceDirect, the Cochrane Library, EMBASE, and PubMed. References to previous reviews and related clinical trials were manually checked to retrieve potential literature that was not included in our electronic search results. RESULTS A total of 10 articles (1 randomized controlled trial, 9 non-randomized controlled trials) were included in the study. The overall number of patients in the dual antiplatelet group was 14,280, and the number of patients in the single antiplatelet group was 125,850. The results revealed that the single antiplatelet group had a lower incidence of 30-day death (rate difference [RD] 0.002; 95% confidence interval [CI] 0.000-0.003; P = 0.014), neck hematoma (odds ratio [OR] 2.120; 95% CI 1.431-3.142; P < 0.001), myocardial infarction (RD 0.004; 95% CI 0.001-0.007; P = 0.003), and major bleeding (RD 0.005; 95% CI 0.002-0.008; P < 0.001). Meanwhile, the single antiplatelet group was associated with a shorter operation time (weighted mean difference 4.000; 95% CI= 2.564-5.436; P < 0.001). However, there was no significant difference in the rate of postoperative transient ischemic attack (P = 0.215), stroke (P = 0.130), or length of stay (P = 0.563). CONCLUSIONS Based on current evidence, using single antiplatelet therapy in CEA may reduce operation time and the incidences of 30-day death, neck hematoma, major bleeding, and myocardial infarction without increasing the risks of transient ischemic attack, stroke, or a longer operation time.

Abstract
Introduction
In the Netherlands, clopidogrel monotherapy increasingly replaces acetylsalicylic acid and extended release dipyridamole as the first-choice antiplatelet therapy after ischemic stroke. It is unknown whether the risk of peri- and postoperative hemorrhage in carotid artery surgery is higher in patients using clopidogrel monotherapy compared with acetylsalicylic acid and extended release dipyridamole. We therefore retrospectively compared occurrence of perioperative major and (clinical relevant) minor bleedings during and after carotid endarterectomy of two groups using different types of platelet aggregation inhibition after changing our daily practice protocol in our center.
Material and Methods
A consecutive series of the most recent 80 carotid endarterectomy patients (November 2015–August 2017) treated with the new regime (clopidogrel monotherapy) were compared with the last 80 (January 2012–November 2015) consecutive patients treated according to the old protocol (acetylsalicylic acid and dipyridamole). The primary endpoint was any major bleeding during surgery or in the first 24 to 72 hours postoperatively. Secondary outcomes within 30 days after surgery included minor (re)bleeding postoperative stroke with persistent or transient neurological deficit, persisting or transient neuropraxia, asymptomatic restenosis or occlusion, (transient) headache. Reporting of this study is in line with the ‘Strengthening the Reporting of Observational Studies in Epidemiology’ statement.
Results
Although statistical differences were observed, from a clinical perspective both patients groups were comparable. Postoperative hemorrhage requiring reexploration for hemostasis occurred in none of the 80 patients in the group of the clopidogrel monotherapy (new protocol) and it occurred in one of the 80 patients (1%) who was using acetylsalicylic acid and dipyridamole (old protocol). In three patients (4%) in the clopidogrel monotherapy and one patient (1%) in the acetylsalicylic acid and extended release dipyridamole protocol an ipsilateral stroke was diagnosed.
Conclusion
In this retrospective consecutive series the incidence of postoperative ischemic complications and perioperative hemorrhage after carotid endarterectomy (CEA) seemed to be comparable in patients using clopidogrel monotherapy versus acetylsalicylic acid and extended release dipyridamole for secondary prevention after a cerebrovascular event. This study fuels the hypothesis that short- and midterm complications of clopidogrel and the combination acetylsalicylic acid and extended release dipyridamole are comparable.

Abstract
BACKGROUND Patients undergoing carotid artery stenosis who are prescribed aspirin, clopidogrel, or sarpogrelate as treatment options to inhibit platelet aggregation continues to increase. The purpose of this study was to compare the efficacy and safety of clopidogrel combined with aspirin (CA) versus sarpogrelate combined with aspirin (SA) treatment in carotid endarterectomy (CEA) patients. METHODS This retrospective study included 197 CEA patients (mean age 61.4 years, mean follow-up time 42.5 months), who were divided into a CA group (Group A: 65 male and 44 female patients) and an SA group (Group B: 58 male and 30 female patients). Preoperative demographic and clinical characteristics and postoperative results were compared between the 2 groups and statistically analyzed. RESULTS Preoperative demographic and clinical characteristics, transfusions, hospital stay, occurrence of transient ischemic attack, stroke, myocardial infarction, restenosis, general or life-threatening bleeding, and 30-day mortality showed no significant differences between the 2 CEA patient groups. However, the mean operative blood loss (P = 0.023) and the operative time (P = 0.040) were significantly higher in Group A compared with Group B. A highly significant incidence of neck hematoma (P = 0.024) was observed in patients of Group A. CONCLUSIONS In this study on CEA patients, antiplatelet treatment with CA resulted in a significant risk of developing neck hematoma, increased operative blood loss, and operative time compared with SA treatment. Long-term prospective studies with larger study populations are needed to further confirm the utility of SA treatment for CEA patients.

Abstract
Stroke is the third leading cause of death in developed nations. Up to 88% of strokes are ischemic in nature. Extracranial carotid artery atherosclerotic disease is the third leading cause of ischemic stroke in the general population and the second most common nontraumatic cause among adults younger than 45 years. This article provides comprehensive, evidence-based recommendations for the management of extracranial atherosclerotic disease, including imaging for screening and diagnosis, medical management, and interventional management.

Abstract
OBJECT Carotid endarterectomy (CEA) carries a small but not insignificant risk of stroke/transient ischemic attack (TIA), most frequently observed within 24 hours of surgery, which can lead to the need for urgent vascular imaging in the immediate postoperative period. However, distinguishing expected versus pathological postoperative changes may not be straightforward on imaging studies of the carotid artery early after CEA. The authors aimed to describe routine versus pathological anatomical findings on CTA performed within 24 hours of CEA, and to evaluate associations between these CTA findings and postoperative stroke/TIA. METHODS The authors reviewed 113 consecutive adult patients who underwent postoperative CTA within 24 hours of CEA at a single academic institution. Presence and location of arterial "flaps," luminal "step-off," intraluminal thrombus and hematoma were documented from postoperative CTA scans. Medical records were reviewed to determine the incidence of new postoperative neurological findings. RESULTS Postoperative CTA findings included common carotid artery (CCA) step-off (63.7%), one or more intraarterial flaps (27.4%), hematoma at the surgical site (15.9%), and new intraluminal thrombus (7.1%). Flaps were seen in the external carotid artery (ECA), internal carotid artery (ICA), and CCA in 18.6%, 9.7%, and 6.2% of patients, respectively. New postoperative neurological findings were present in 7.1% of patients undergoing CTA. Flaps (especially ICA/CCA) and/or intraluminal thrombi were more frequently seen in patients undergoing CTA for new postoperative stroke/TIA (85.7%) versus patients undergoing CTA for routine postoperative imaging (14.3%, p = 0.002). CONCLUSIONS CTA within 24 hours of CEA demonstrates characteristic anatomical findings. CCA step-offs and ECA flaps are relatively common and clinically insignificant, whereas ICA/CCA flaps and thrombi are less frequently seen and are associated with postoperative stroke/TIA.

Abstract
OBJECTIVE Cranial nerve palsy (CNP) and neck haematoma are complications of carotid endarterectomy (CEA). The effects of patient factors and surgical technique were analysed on the risk, and impact on disability, of CNP or haematoma in the surgical arm of the International Carotid Stenting Study (ICSS), a randomized controlled clinical trial of stenting versus CEA in patients with symptomatic carotid stenosis. MATERIALS AND METHODS A per-protocol analysis of early outcome in patients receiving CEA in ICSS is reported. Haematoma was defined by the surgeon. CNP was confirmed by an independent neurologist. Factors associated with the risk of CNP and haematoma were investigated in a binomial regression analysis. RESULTS Of the patients undergoing CEA, 45/821 (5.5%) developed CNP, one of which was disabling (modified Rankin score = 3 at 1 month). Twenty-eight (3.4%) developed severe haematoma. Twelve patients with haematoma also had CNP, a significant association (p < .01). Independent risk factors modifying the risk of CNP were cardiac failure (risk ratio [RR] 2.66, 95% CI 1.11 to 6.40), female sex (RR 1.80, 95% CI 1.02 to 3.20), the degree of contralateral carotid stenosis, and time from randomization to treatment >14 days (RR 3.33, 95% CI 1.05 to 10.57). The risk of haematoma was increased in women, by the prescription of anticoagulant drugs pre-procedure and in patients with atrial fibrillation, and was decreased in patients in whom a shunt was used and in those with a higher baseline cholesterol level. CONCLUSIONS CNP remains relatively common after CEA, but is rarely disabling. Women should be warned about an increased risk. Attention to haemostasis might reduce the incidence of CNP. ICSS is a registered clinical trial: ISRCTN 25337470.

Abstract
This review examines the role of platelets in ischemic stroke, platelet activation mechanisms, aspirin's rise as an antithrombotic agent, clopidogrel's appearance on the stage, a possible role for combination therapy, antiplatelet resistance, practical considerations, and future directions. Reviewed in this chapter are issues central to optimal antiplatelet therapy: efficacy, safety, resistance, and biochemical/laboratory testing. Current guidelines do not recommend combination aspirin and clopidogrel use, however recent research indicates dual antiplatelet therapy with combined aspirin and clopidogrel may have specific roles in secondary prevention of ischemic stroke. A cautious and analytical interpretation of the literature is advised before application of this knowledge to clinical practice. The best recommendation at this time is to follow the published guidelines for secondary prevention of ischemic stroke.
