ABSTRACT
The authors report four cases of aneurysm of the anterior cerebral artery proximal to the anterior communicating artery(A1 segment). In three of these cases, the aneurysms arose from the distal A1 segment. In one case the aneurysm arose from the proximal A1 segment. The aneurysms were saccular in three cases and fusiform in a case. Hypoplasia of A1 segment was not present in any of these cases. Three saccular aneurysms were clipped and a fusiform aneurysm was trapped. Prognosis was good in two cases, poor in other two cases.
Key Words: Aneurysm; A1 segment; Anterior cerebral artery
