Analyze the safety and effectiveness of low-profile visualized intraluminal support (LVIS) stent-assisted coil embolization in the treatment of intracranial wide neck ruptured aneurysms.

Forty-three patients with subarachnoid hemorrhage caused by wide neck ruptured aneurysm treated with LVIS stent-assisted coil embolization in the Department of Neurosurgery, the Second Affiliated Hospital of Nanchang University from July 2016 to July 2017 were analyzed retrospectively. The modified Raymond classification standard was used to evaluate the embolization results and the degree of occlusion of the most recent aneurysm immediately after surgery and 6 months after surgery. The modified Rankin score (mRs) was used to evaluate the postoperative efficacy of the patients.

There were 47 aneurysms in 43 patients with intracranial wide neck ruptured aneurysms and subarachnoid hemorrhage, 2(4.6%) patients were multiple aneurysms, all of which were successfully embolized. In 43 patients with aneurysms, 1(2.3%) had ruptured aneurysm and bleeding during operation, and 2(4.6%) had acute thrombus in stent during operation; immediate occlusion after operation: 35 (81.4%) patients with grade Ⅰ embolization, 6 (13.9%) patients with grade Ⅱ embolization, and 2 (4.7%) patients with grade Ⅲ embolization; 6-month follow-up results: 40 (93.0%) patients with grade Ⅰ embolization, 2 (7.0%) patients with grade Ⅱ embolization, 1 (2.3%) had relapse, and they were re-embolized later 41 (95.3%) cases had mRs score of 0-2 in 1 year after operation.

LVIS stent-assisted coil embolization is a safe and effective treatment for intracranial wide-neck ruptured aneurysms. Further long term follow-up studies will be necessary to confirm its long-term efficacy.
