AComA aneurysms are most commonly found at the A1-A2 junction on the dominant side. The angle of the arteries at the bifurcation and the direction of blood flow are factors of hemodynamic stress in the apical region where these aneurysms often develop. They exist at the bifurcation of dominant A1, A2 and AComA and usually point in the direction away from the dominant A1. They are more prone to rupture and demonstrate the highest incidence of post-operative morbidity among anterior circulation aneurysms. Consideration of aneurysm morphology may be used to guide approaches in AComA aneurysms. Resection of the gyrus rectus in combination with a pterional approach was popularized by Yasargil and it became the standard for treatment or exposure of AComA aneurysms, although other skull base approaches are also widely used. Clip selection is of extreme importance and the preservation of blood flow to the perforators should be emphasized. Adequate dissection and exposure of the entire "H" complex prior to clipping is the key to a successful outcome. Separating the perforators from the neck or dome of the artery and preserving the parent vessel presents a substantial challenge to the surgeon when the aneurysm is behind the parent artery, making it difficult to achieve a good outcome.
