{Abstract}: <B>BACKGROUND: </B>The Low-Profile Visualized Intraluminal Support (LVIS) device has been frequently used as an intracranial stent for treating intracranial aneurysms. However, the feasibility and efficacy of LVIS devices in Y-stent-assisted coiling (Y-SAC) have remained contentious. This study aimed to evaluate long-term angiographic and clinical outcomes of Y-SAC using LVIS devices.<BR><B>METHODS: </B>We retrospectively reviewed the clinical presentation and angiography data of patients treated with Y-SAC using LVIS stents. The vascular angle geometry between the parent and the 2 branch vessels, before and after stent deployment and after coiling, were analyzed. Based on the Raymond-Roy Occlusion Classification (RROC), aneurysm occlusion status was classified. Clinical outcomes were assessed using the modified Rankin Scale.<BR><B>RESULTS: </B>Forty patients with 40 aneurysms were included in this study. Immediate postprocedural angiograms showed complete/near-complete occlusion (RROC 1 and 2) in 31 aneurysms (77.5%). The long-term follow-up angiographic studies were available in 32 patients and showed RROC class 1 and 2 in 93.8% of patients. Y-SAC with LVIS devices significantly decreased the angle between the bifurcation branches from 171.90° ± 48.0° (standard deviation) to 130.21° ± 46.3° (standard deviation) (P < 0.0001). Periprocedural complications occurred in 5 patients (12.5%) including 4 in-stent thromboses (10.5%). Thirty-six patients (90.0%) had favorable clinical outcomes at the final follow-up. Univariate analysis showed that World Federation of Neurological Societies grade 3-5, thickness of subarachnoid hemorrhage on head computed tomography, intraprocedural complications, and in-stent thrombosis were predictors of poor outcome.<BR><B>CONCLUSIONS: </B>Y-SAC using the LVIS device for intracranial bifurcation aneurysms is a feasible and relatively safe procedure with favorable long-term angiographic and clinical outcomes.
