Abstract

Abstract:

Objective:

To evaluste the clinical efficacy and safety of the LVIS stent for embolization of ruptured intracranial saccular aneurysms.

Methods:

A total of 230 patients with ruptured intracranial saccular aneurysms treated using the LVIS device in our center between April 2014 and February 2018 were reviewed. The primary outcomes were procedural safety, target aneurysm recurrence, and mid-term follow-up of clinical and angiographic outcomes.

Results:

230 patients with intracranial saccular aneurysms were treated using LVIS stents, no failed. Immediate angiographic outcome evaluation showed complete occlusion in 205 (89%) and neck remnant in 25 (11%) . Of the 180 patients who underwent angiographic follow-up at a mean of 12 months, complete occlusion was achieved in 162 (90%) patients. In the remaining patients, neck remnant in 17 (9.4%) and 1 (0.6%) patient were recurrence. There were 24 cases of complications. 1 case of bleeding event, 1 case of rebleeding event. 12 (5.2%) patients had in-stent thrombosis in the process of embolization and 3 patients had ischemia events. And the ischemia events was 10 after operation. The morbality rate was 3.5% and mortality was 0.8% of all the complications.

Conclusions:

The LVIS stent is safe and effective in the treatment of ruptured intracranial saccular aneurysms.
