Small Lobulated Aneurysm: Balloon-Assisted Coiling
A 37-year-old lady presented with subarachnoid haemorrhage (Hunt and Hess Grade III; Fisher Grade IV). The angiogram revealed a small but broad-neck anterior communicating artery aneurysm filling from left internal carotid artery injection. Both anterior cerebral arteries were filling from left side with absence of A1 segment of right ACA. The aneurysm had a lobule projecting from the fundus (Fig. 10.1) as well a small lobule near the neck. Balloon-assisted coiling was planned.
