Feasibility & Limitations of Endovascular Coil Embolization of Anterior Communicating Artery Aneurysms

ABSTRACT

OBJECTIVE: The purpose of this study is to analyze aneurysm morphology and define limitations and feasibility in endovascular Gugliemi detachable coil(GDC) embolization for anterior communicating artery (ACoA) aneurysms. METHODS: From January 2000 through October 2003, 123patients were treated with endovascular coil embolization for ACoA aneurysms. There were 75women and 48men, with a mean age of 63years. All ruptured aneurysms were treated within 15days of rupture. Aneurysm morphology was classified according to neck size and projection of aneurysm dome as follows - A: neck of aneurysm or =4mm) aneurysms are highly related to recanalization of aneurysms. CONCLUSION: Endovascular coil embolization of ACoA aneurysms shows good outcome in our study. Nevertheless, there is a limitation in the endovascular approach to ACoA, even though advanced modern techniques evolve rapidly. Compensatory surgical approach with the endovascular approach is required for successful treatment of ACoA aneurysms.
