Abstract

Introduction/purpose Low-profile self-expandable stents were recently introduced for the treatment of wide-necked intracranial aneurysms. This study investigated the initial and mid-term clinical and angiographic results of Leo baby stent-assisted coiling treatment of wide-necked intracranial aneurysms.

Materials and methods We retrospectively identified eighty patients with 80 wide-necked intracranial aneurysms who were all treated with Leo baby stent-assisted coiling. Eleven patients (13.8%) presented with subarachnoid hemorrhage. Technical success, immediate post-procedural clinical and angiographic outcomes were analyzed. Seventy-three patients had angiographic and clinical follow-ups for a mean duration of 7.2 ± 3.8 months. Peri-procedural and delayed complications were reviewed. Clinical status was assessed using the modified Rankin Scale, prior to the procedure and at follow-up.

Results The technical success rate of the procedure was 97.5%. There was complete occlusion of the aneurysm in 75% of the 80 patients on immediate post-procedural angiography. The last follow-up angiograms showed a complete occlusion in 85.7% of the 73 patients with an angiographic follow-up. Of the 73 patients with a follow-up angiography, 6.5% showed an increase in the filling status of the aneurysm and 5.2% required retreatment. The overall procedure-related complication rate, including asymptomatic complications, was 11.3%. The permanent morbidity rate was 3.8%. There was no mortality in this study.

Conclusions This case series demonstrates the relative safety, efficacy and mid-term durability of the Leo baby stent-assisted coiling procedure for the treatment of wide-necked intracranial aneurysms.
