Abstract Introduction The aim of this prospective study was to evaluate the efficacy and safety of carotid endarterectomy for symptomatic carotid stenosis during the COVID-19 pandemic. Method Re-organisation of stroke services due to the COVID-19 pandemic resulted in carotid endarterectomy for symptomatic disease being performed in two hospitals; Covid-19 free and non-free sites. Patients were referred from multiple online regional neurovascular multi-disciplinary team meetings, and managed according to the pre-Covid-19 guidance. All patients referred for carotid endarterectomy between 23 March 2020 and 31 July 2020 were included. Demographic, medical history, imaging, peri-operative, complication and follow-up data were collected and analysed prospectively. Result 28 patients were referred for carotid endarterectomy, of whom 21 patients underwent surgery. The mean time to surgery was 11 days (3–35). The technical success rate was 100%. Peri-operatively and within 30-days post-operatively, no patient suffered death or stroke. There were 2 minor complications; one non-ST elevation myocardial infarction, and another wound haematoma and infection requiring readmission for antibiotics. No patient developed new COVID-19 infection post-operatively. Of the 7 patients not operated on; 2 were medically unfit for surgery, three declined surgery, and two had free floating thrombus that was managed successfully with anti-coagulation. Conclusion During the pandemic, the provision of carotid endarterectomy for symptomatic carotid diseases was carried out safely and within the current recommendations, with several pre-cautionary measures being undertaken. Therefore, symptomatic carotid intervention should still be considered to reduce the risk of stroke provided similar pre-cautionary measures are undertaken. Take-home Message Carotid surgery should continue during successive waves of the COVID-19 pandemic

This chapter provides a summary of the landmark surgical study known as the NASCET trial, which compared surgical versus nonsurgical treatment for patients with symptomatic carotid stenosis. The chapter describes the basics of the study, including funding, year study began, year study was published, study location, who was studied, who was excluded, how many patients, study design, study intervention, follow-up, endpoints, results, and criticism and limitations. The chapter briefly reviews other relevant studies and information, gives a summary and discusses implications, and concludes with a relevant clinical case regarding vascular surgery.

Abstract OBJECTIVE AND IMPORTANCE: Cerebral ischemia is the most worrisome perioperative complication of carotid endarterectomy (CEA). The stroke rate occurring with CEA is estimated to range from 2.3 to 6.3%. Numerous treatment options are available to the neurosurgeon in this scenario, although no “gold standard” exists. CLINICAL PRESENTATION: A 61-year-old woman presented with acute left arm weakness 40 minutes after an uneventful CEA for symptomatic carotid stenosis. Emergent angiography demonstrated vascular irregularities in a “moth-eaten” pattern along the arteriotomy closure, suggestive of platelet-fibrin aggregates (“white clot”). INTERVENTION: Abciximab was immediately administered intravenously in the angiography suite, with subsequent improvement of the visualized vascular irregularities on a second angiogram performed 12 minutes after infusion and complete resolution of the presumed platelet-fibrin aggregates on a third angiogram performed the next day. The patient had no further episodes of cerebral ischemia. She was discharged home on the fifth postoperative day with improving left arm weakness, which had completely resolved by her 2-month follow-up visit. CONCLUSION: To our knowledge, this is the first reported case of abciximab administered intravenously in the setting of acute thromboembolic brain ischemia after CEA. For the unique situation in which an acute thrombus, or white clot, is thought to be the cause of cerebral ischemia, we believe that abciximab may offer an effective and potentially safer alternative than fibrinolytics and may be a more appropriate drug to use from a physiological perspective.

BackgroundCerebral microemboli may lead to ischaemic neurological complications after carotid endarterectomy (CEA). The association between classical cardiovascular risk factors and acute cerebral microemboli following carotid surgery has not been studied. The aim of this study was to explore whether an established cardiovascular risk score (Pocock score) predicts the presence of cerebral microemboli acutely after CEA.Subjects and methodsPocock scores were assessed for the 670 patients from the Carotid Surgery Registry (age 71±1 (SEM) years, 474 (71%) male, 652 (97%) Caucasian) managed from January 2002 to December 2012 in the Regional Vascular Centre at University Hospitals Coventry and Warwickshire NHS Trust, which serves a population of 950 000. CEA was undertaken in 474 (71%) patients for symptomatic carotid stenosis and in 196 (25%) asymptomatic patients during the same period. 74% of patients were hypertensive, 71% were smokers and 49% had hypercholesterolaemia.ResultsA high Pocock score (≥2.3%) was significantly associated with evidence of cerebral microemboli acutely following CEA (P=0.039, Mann-Whitney (MW) test). A Pocock score (≥2.3%) did not predict patients who required additional antiplatelet therapy (microemboli signal (MES) rate >50 hour-1: P=0.164, MW test). Receiver operating characteristic analysis also showed that the Pocock score predicts acute postoperative microemboli (area under the curve (AUC) 0.546, 95% CI 0.502 to 0.590, P=0.039) but not a high rate of postoperative microemboli (MES >50 hour−1: AUC 0.546, 95% CI 0.482 to 0.610, P=0.164). A Pocock score ≥2.3% showed a sensitivity of 74% for the presence of acute postoperative cerebral microemboli. A Pocock score ≥2.3% also showed a sensitivity of 77% and a negative predictive value of 90% for patients who developed a high microembolic rate >50 hour−1 after carotid surgery.ConclusionThese findings demonstrate that the Pocock score could be used as a clinical tool to identify patients at high risk of developing acute postoperative microemboli.

Patients with symptomatic carotid stenosis benefit from revascularization. The risk of recurrent stroke is highest during the early period after a transient ischemic attack or stroke. Carotid endarterectomy and carotid stenting are options for treatment and should be considered within the first 2 weeks if feasible.
