Abstract：Objective To investigate the effect of endovascular treatment of intracranial ruptured vertebral artery dissecting aneurysms via bilateral vertebral artery approach. Methods The symptoms and imaging results of 5 patients with ruptured vertebral artery dissecting aneurysms were analyzed retrospectively. They were all treated with coil embolization via bilateral vertebral artery approach. The two ends of dissection aneurysms were packed densely,the middle segments were packed loosely,and the arteries were isolated from the blood circulation. Results Of the 5 patients after treated,the clinical symptoms were improved rapidly in 4 patients no abnormal limbs activity and mental disorders. After treatment,the modified Rankin scale (mRS)was 0 in four cases after six-month follow-up. One patient turned clear consciousness after 4 weeks, and their mRS was 3 at 6-month follow-up. Before treatment,DSA showed vertebral artery dilation and stenosis. The mean length of involvement in vertebral arteries was 9. 3 ± 1. 5 mm;after treatment,the dissecting aneurysms of 5 patients did not develop completely,no further bleeding occurred,and no new infarcts were observed. No recurrence of the aneurysms and parent artery recanalization were found at the follow-up after 6 months. Conclusion The occlusion of ruptured vertebral artery dissecting aneurysms via bilateral vertebral artery approach is technically feasible. It may be an effective treatment to prevent rebleeding.
