Surgical treatment of aneurysms of the anterior cerebral artery.

Cerebral aneurysms occur on the anterior cerebral artery in three locations: the anterior communicating artery, the pericallosal artery, and the A1 segment. Anterior communicating artery aneurysms show great morphologic variability and are the most frequent aneurysms seen in modern series. The anatomy, management, neuroradiology, surgical technique, and clinical outcome referable to each location on the anterior cerebral artery are discussed in this article.
