Intracranial Complex Ruptured Aneurysms Coiled with Overlapping Low-Profile Visualized Intraluminal Support Stents: Another Available Option for Complex Ruptured Intracranial Aneurysms

BACKGROUND: Overlapping stents represent a new paradigm in endovascular interventions, especially for complex and wide-necked aneurysms. The low-profile visualized intraluminal support (LVIS) device is a new generation of self-expanding braided stents recently introduced in China for stent-assisted coiling of intracranial aneurysms. We report several cases of intracranial aneurysms coiled using overlapping LVIS stents to evaluate its efficacy and safety. METHODS: Patients with ruptured intracranial aneurysms treated with double LVIS stents at our center between November 2014 and May 2016 were reviewed. The clinical data and technical results are presented. RESULTS: Ten patients with 15 aneurysms were treated with double LVIS stents, with a 100% technical success rate. No mortality was observed. Immediate angiographic outcome evaluation showed complete occlusion in 13 aneurysms (86.7%) and neck remnants in 2 aneurysms (13.3%). CONCLUSIONS: Double LVIS stents are safe and effective in the treatment of intracranial aneurysms, especially complex aneurysms.
