ObjectiveTo evaluate the safety and efficacy of stent-only technique with Low-profile Visualized Intraluminal Support (LVIS) for uncoilable intracranial aneurysms.MethodsTwelve uncoilable aneurysms in 12 patients were treated with the stent-only technique in our department from January 1, 2016, to December 31, 2017. The characteristics of the aneurysms and the patients were analyzed. The midterm follow-up results of these patients also were analyzed.ResultsTwelve patients (7 male and 5 female) were enrolled in the series. The 12 aneurysms included 6 vertebral-basilar artery aneurysms, 3 internal carotid artery aneurysms (2 blood blister-like aneurysms and 1 posterior communicating artery aneurysm), 1 posterior cerebral artery dissecting, 1 anterior cerebral artery dissecting of the third segment, and 1 pseudoaneurysm at the first segment of the anterior cerebral artery. Seven aneurysms were? ruptured, whereas 5 remained unruptured. A total of 24 LVIS stents were deployed. Three aneurysms were covered by 3 overlapped stents, 6 aneurysms were covered by 2 stents, and the other 3 aneurysms were covered by 1 stent. All procedures were successful without any perioperative complications. Imaging follow-up between 3 and 10 months after operation was available in all 12 patients, with complete obliteration in 10 aneurysms, improvement in 1, and parent artery occlusion in 1.ConclusionsLVIS stent-only technique is safe and efficacious for uncoilable aneurysms, even for ruptured ones.Copyright © 2019.
