Abstract：Objective To explore the efficacy of dual LVIS stent overlap technique-assisted coil embolization for ruptured vertebrobasilar artery dissecting aneurysms in the acute stage. Methods The clinical data of 13 patients with ruptured vertebrobasilar artery dissecting aneurysms treated with dual LVIS stent overlap technique-assisted coil embolization from October 2019 to September 2022 were retrospectively analyzed. Results On admission,there were 5 cases of Hunt-Hess grade Ⅰ,4 cases of grade Ⅱ,3 cases of grade Ⅲ,and 1 case of grade Ⅳ. The aneurysms were located in the basilar artery in 1 case and the vertebral artery in 12 cases[6 cases at the distal posterior inferior cerebellar artery (PICA),4 cases at the proximal PICA,and 2 cases involving the PICA]. The time from onset to admission was 2～18 hours,with an average of (7.20±1.55) hours. Immediate postoperative angiography showed Raymond grade Ⅰ in 9 cases and grade Ⅱ in 4 cases. Perioperative complications occurred in 4 cases (30.77％),of whom 3 cases (23.08％) had ischemic complications within 24 hours after surgery,and 1 case died due to re-rupture and hemorrhage of the aneurysm. At discharge,the modified Rankin Scale (mRS) score was 1 in 4 cases,2 in 3 cases,3 in 3 cases,and 4 in 2 cases;at 6-month follow-up after surgery,the mRS score was 0 in 6 cases,1 in 5 cases,and 2 in 1 case. Angiography follow-up at 6 months after surgery showed no aneurysm in 12 cases,and the parent arteries were patent. Conclusion In the acute stage of ruptured vertebrobasilar artery dissecting aneurysms,dual LVIS stent overlap technique-assisted coil embolization has high safety and can effectively improve the prognosis of patients.
