Abstract

Objective: To analyze the efficacy and follow-up results of endovascular treatment of very small intracranial aneurysms with relatively wide neck. Methods: 43(41 patients) very small intracranial aneurysms with relatively wide neck were treated with stent-assisted coil embolization. Immediate postprocedural and follow-up data were retrospectively evaluated. Follow-up results were achieved in all patients, and the main outcome was measured with modified Rankin scale(mRS). Angiography follow-up data were available in 15 patients. Results: Grade 0 occlusion was achieved in 12 aneurysms, Grade 1 in 26 aneurysms, and 5 aneurysms were failed to embolize. Cerebral infarction was encountered in 2 patients. During follow-up(mean time duration was 16.3 months), Modified Rankin Scale was 0 in 30 cases, 1 in 6 cases, 2 in 2 cases, 3 in 1 cases, and 5 in 1 case. Conclusions: Endovascular treatment can be performed safely and effectively in very small intracranial aneurysms with relatively wide neck.
