Background and purpose: Endovascular treatment for ruptured cerebral aneurysms ≤ 3 mm in diameter is controversial because it is associated with a high risk of rupture during the procedure. The aim of this study is to evaluate safety and efficacy of endovascular treatment by selecting an appropriate supporting point and shaping of microcatheter in accordance with the blood vessel running for ruptured small anterior communicating aneurysms.
Material and Methods: Thirteen patients with ruptured small anterior communicating artery aneurysms who underwent endovascular treatment at our hospital or affiliated hospitals during the past 10 years were included. There were 3 men and 10 women, with a mean age of 69.8 (40-94) years. The mean major axis diameter was 2.5 (1.9-3.0) mm. All endovascular treatment procedures were performed by selecting an appropriate supporting point and shaping of microcatheter in accordance with the vessel running.
Technical success rate, immediate angiographical results, periprocedural complication within 30 day, and follow-up result were retrospectively assessed.
Results: Technical success rate was 100% (13/13). No periprocedural complication occurred. There were 4 cases of complete occlusion, 8 of neck remnant, and one of body filling. Patients were followed-up for a mean 57.3 (6-112) months, and no rebleeding or recurrent aneurysm was noted.
Conclusions: Endovascular treatment for ruptured small anterior communicating artery by making an appropriate supporting point and shaping of microcatheter in accordance with the blood vessel running seems be safe and efficacy to prevent rebleeding of aneurysm.
