Abstract：Objective To explore the clinical characteristics,treatment methods,and therapeutic effects of dissecting aneurysms of the V4 segment of the vertebral artery. Methods The clinical data of 10 patients with dissecting aneurysms of the V4 segment of the vertebral artery admitted from January 2017 to June 2023 were retrospectively analyzed. Results All 10 patients presented with acute hemorrhage. Before the operation,1 patient was classified as Hunt-Hess grade Ⅰ,5 as grade Ⅱ,and 4 as grade Ⅲ. Three patients were treated with simple coil embolization,2 with stent-assisted coil embolization,and 5 with coil embolization plus occlusion of the parent artery. Immediate postoperative angiography showed that the complete or near-complete occlusion rate of aneurysms was 100％. No recurrence of aneurysms was found during the follow-up period. One patient died due to acute thrombosis within the stent after the operation,and the remaining 9 patients recovered well after the operation (GOS score of 4～5). Conclusions Dissecting aneurysms of the V4 segment of the vertebral artery are an important cause of stroke in young and middle-aged people,with diverse clinical manifestations. For patients with surgical indications,endovascular treatment is the preferred option,and the specific treatment plan needs to be individualized based on the patient's specific situation.
