1 Fig. 3. (A) The condition after bypass and before temporary clip removal. (B) Schematic drawing of the treatment plan for the giant serpentine aneurysm (GSA) in the distal anterior cerebral artery (ACA). α: In situ "side-to-side" bypass of both distal ACAs, β: Occlusion of the entry channel via an endovascular approach using detachable coils. Occlusion is performed in 2 steps. First, the distal widest part of the GSA is loosely packed using large coils (green helix). Second, the proximal narrow part between the distal perforator of the feeding artery and the beginning of the aneurysm is densely packed using coils (blue helix). Fig. 3.
