Abstract：Objective To investigate the feasibility, safety and efficacy of LVIS stent assisted coil embolization in the treatment of intracranial aneurysms. Methods The clinical data of 83 patients (89 aneurysms) with intracranial aneurysms treated with LVIS stent-assisted coil embolization from May 2014 to September 2017 in Department of Neurosurgery, General Hospital of Ningxia Medical University were retrospectively analyzed. Results A total of 90 LIVS stents were used. Two LVIS stent-assistances were used in one aneurysm. All stents were released in parallel with the microcatheter. Sixty-one stents were used by complete-releasing and 28 by semi-releasing during the embolization. The DSA immediately after the embolization showed that Raymond grade Ⅰ occlusion was achieved in 64 aneurysms, grade Ⅱ in 22, and grade Ⅲ in 3. The intraoperative thrombosis occurred in 4 patients oh whom 3 were stent thrombosis. The intraoperative aneurysm rupture occurred in 1 patient. The postoperative follow-up ranged from 4 to 36 months. The reexaming DSA of 52 patients showed that the aneurysms with initial Raymond grade Ⅱ occlusion were changed in to grade Ⅰ in 6 patients, and the recurrence of the aneurysms occurred in 3 patients. Sixty-three patients had modified Rankin scale score of 0 to 1 points, 9 had 2 points, and 11 had 3 points or more than. Conclusions The LVIS stent-assisted coil embolization is a feasible, safe and effective treatment for intracranial aneurysms. However, the problems including the stent thrombosis events and how to choose the appropriate stents are still worth exploring.
