Double microcatheter technique for the treatment of irregular and wide-neck anterior communicating aneurysm

Abstract

The purpose of this study is to evaluate the feasibility, complication and follow-up results of intrasaccular double microcatheter endovascular coil embolization of irregular and wide-neck anterior communicating aneurysm aneurysm. From July 2012 to December 2015, 11 cases with irregular and wide-neck anterior communicating aneurysm treated with double microcatheter technique were selected. All patients were admitted in our department with subarachnoid hemorrhage, The results, complications, and follow-up results were assessed. All anterior communicating aneurysms were successfully treated by using double microcatheter technique. The mean aneurysm neck size was 3.8 mm. The mean dome-to-neck ratio was 1.35. Immediate post-embolization angiograms demonstrated complete occlusion in 8 of 11 aneurysms. Near complete in 3. Imaging follow-ups were performed with magnetic resonance angiography or digital subtraction angiography for more than 12 moths. All cases showed stable occlusion. In conclusions, double microcatheter technique may be a safe and good technique for the treatment of irregular and wide-neck anterior communicating aneurysm aneurysm.
