Abstract:
Objective:To investigate the efficacy and safety of different stents assisted embolization in the treatment of subarachnoid hemorrhage(SAH) caused by V4 dissecting aneurysm of vertebral artery.Methods:The clinical data of 39 patients with spontaneous SAH V4 dissecting aneurysm treated at the Department of Neurosurgery, the Northern Theater General Hospital from January 2016 to June 2019 were analyzed retrospectively.There were 21 males and 18 females, aged (48±17) years(range:35 to 68 years).There were 24 cases of HUNT-HESS grade Ⅰ and 15 cases of grade Ⅱ.Among them, 20 cases were treated with single stent-assisted embolization, 9 cases with multi-stent-assisted embolization, 9 cases with semi-dense mesh-assisted embolization, and 1 case with dense-mesh stent-assisted embolization.The perioperative and postoperative complications, postoperative recurrence were collected.Results:Intraoperative complications included 2 cases of aneurysm rupture and 2 cases of acute thrombosis.All aneurysms were densely packed according to the angiography performed immediately after operation.Postoperative complications included 3 cases of long-term responsible vascular ischemia(modified Rankin score<2). The patients were followed up for 15.1 months(range: 12 to 29 months). At the last follow-up, aneurysms recurrence occured in 10 cases, the recurrence rate was 25.6%(10/39). There were 6 cases of recurrence and 2 cases of complications in 20 cases with single stent-assisted embolization, 3 cases of recurrence and 4 cases of complications in 9 cases with multi-stent-assisted embolization, 1 case of recurrence and 1 case of complications in 9 cases with semi-dense mesh stent.Conclusion:Endovascular treatment is feasible for patients with vertebral artery dissecting aneurysm, and the appropriate surgical method should be selected according to the vascular structure and the location of the aneurysm.
