Abstract: Anterior communicating artery aneurysms are among the most commonly encountered aneurysms in neurosurgical practice. While many are treatable using modern endovascular techniques, because of their often complex anatomy, both ruptured and unruptured anterior communicating artery aneurysms often require microsurgical treatment. Pre-operative analysis of the collateral circulation, the aneurysm orientation, the aneurysm height, morphology, and the dome-to-neck ratio can all affect decision-making. For unruptured aneurysms, a careful analysis of the natural history of rupture risk versus the risks of surgery or endovascular treatment will determine if treatment is recommended and what modality. At surgery, perforating artery preservation is of utmost importance. This chapter discusses these issues as considered in the management of an incidental, unruptured anterior communicating artery aneurysm.
