Background:
Middle cerebral artery (MCA) aneurysms often occur in small parent vessels and are incorporated with the orifice of acute-angled efferent branch vessels. Endovascular treatment for these aneurysms remains technically challenging. This study aimed to assess the clinical safety and efficacy of the Low-profile Visualized Intraluminal Support Junior (LVIS Jr) stent for embolization of MCA aneurysms.
Methods:
Eighteen intracranial aneurysms, including 13 unruptured and 5 ruptured aneurysms, were treated with LVIS Jr stent-assisted coil embolization. The clinical data and technical results are presented.
Results:
A total of 18 stents were successfully delivered to the target aneurysms, and the technical success rate was 100%. There was complete occlusion in 8 (44.4%) of 18 cases, neck remnants in 7 (38.9%) cases, and partial occlusion in 3 (16.7%) cases. In-stent thrombosis occurred in 1 case, and the symptoms disappeared after transvenous tirofiban injection. The modified Rankin Scale score at discharge was 0 in 14 patients, 1 in 3 patients, and 2 in 1 patient.
Conclusions:
The LVIS Jr stent provided excellent trackability and deliverability and is safe and effective for the treatment of wide-necked MCA aneurysms with tortuous and smaller parent vessels.
