Carotid stump syndrome:A case series study and literature review
Objective To investigate the clinical efficacy of endovascular intervention in the treatment of acute ischemic stroke caused by carotid stump syndrome(CSS).Methods A retrospective analysis was performed for the patients with anterior circulation acute ischemic stroke who underwent endovascular intervention in The First Hospital of Jilin University from August 2018 to October 2022,among whom the patients with acute ischemic stroke caused by CSS were identified,and related data were collected for these patients,including demographic information,risk factors,surgery-related characteristics,and prognosis.Results A total of 23 patients met the diagnostic criteria for CSS,among whom 19 patients achieved successful revascularization and 7 achieved extended Thrombolysis in Cerebral Infarction(eTICI)grade 3.Fourteen patients received concurrent carotid artery stenting.Twelve patients experienced intracranial hemorrhage after surgery,among whom 1 patient experienced symptomatic intracranial hemorrhage(sICH)leading to in-hospital death.On day 90 after onset,8 patients achieved functional independence,with a modified Rankin Scale score of≤2,while 4 patients died within 90 days.Conclusion CSS is a clinical syndrome caused by embolization from the occluded distal portion of the internal carotid artery.Endovascular intervention is an effective method for the treatment of CSS.
