Broad Neck Dysplastic Anterior Communicating Artery Aneurysm: Compartmental Packing
A 66-year-old female presented with subarachnoid hemorrhage (Hunt and Hess IV). The angiogram revealed an anterior communicating artery aneurysm (Fig. 39.1). The aneurysm had a broad neck involving origin of both the anterior cerebral arteries. The A1 segment of left ACA was absent. Two lobules were seen near the neck of aneurysm (Fig. 39.1c). Balloon-assisted coiling was planned.
