Anterior Communicating Aneurysm: Its Surgical Approach and Result

Abstract

The anterior communicating artery (ACOA) region is the most common site for ruptured intracranial aneurysms. These aneurysms lie deep within important brain structures, requiring a difficult surgical approach for obliteration. However, the management mortality and morbidity of patients with these aneurysms can be considerably reduced by appreciating their natural history, physiological factors of circulation, morphological features and the pathological changes involved following subarachnoid hemorrhage (SAH). Recurrent rupture remains more of a threat than ischemic problems from these aneurysms and their obliteration at the earliest possible time is not only feasible but helpful for an improved outcome.
