Endovascular treatment for vertebral artery stenosis ectopic originating from aortic arch:clinical data analysis of 5 patients
Objective To summarize the feasibility and effectiveness of endovascular treatment for vertebral artery stenosis ectopic originating from the aortic arch.Method The clinical data of 5 patients with vertebral artery stenosis ectopic originating from aortic arch admitted to Xuanwu Hospital of Capital Medical University from January 2020 to May 2023 were retrospectively analyzed.Results All 5 patients underwent magnetic resonance angiography and CT angiography before treatment.The vertebral arteries of all patients originated from the aortic arch and were severe stenosis,with a median diameter of 1.3 mm(range,1.1-1.5 mm)by CT angiography.All 5 patients were successfully treated with endovascular intervention.The operation time was 37-45 min,with a median of 39 min.There were no complications of vertebral artery rupture,embolism or occlusion,cerebral infarction,plaque abscission,hematoma at puncture site,pseudoaneurysm,postoperative hemorrhage,or perioperative pulmonary infection.The patients were followed-up for 13-30 months,with a median follow-up time of 20 months.The blood vessels of 5 patients remained unobstructed and no clinically significant vascular restenosis occurred.Conclusions Based on the experiences of 5 cases of vertebral artery stenosis ectopic originating from the aortic arch,it is safe and effective to choose endovascular treatment for severe symptomatic vertebral artery stenosis.Especially,it is necessary to evaluate the stenosis degree of vertebral artery using CT angiography before treatment.
