Endovascular Treatment for Anterior Communicating Artery Aneurysms

Previously, anterior communicating artery aneurysms were considered unsuitable for endovascular treatment. In recent years, however, endovascular treatment has been increasingly performed due to the fact that it is less likely to cause high dysfunction compared to surgery and the treatment has been improved. The International Subarachnoid Aneurysm Trial reported anterior communicating artery aneurysms comprise 45.4% of cerebral aneurysms on which both endovascular treatment and surgery are suitable. The use of the endovascular treatment for anterior communicating artery aneurysms is expected to increase in the future. In this paper, we present cases from our institution based on the characteristics of anterior and distal communicating artery aneurysms, treatment strategies, and treatment indications.
