Abstract:
Anterior communicating artery aneurysms (ACoAA) accounts for about 30% of all intracranial aneurysms, and their occurrence and morphology are closely related to A1 segment of anterior cerebral artery. The dominant blood supply of A1 segment of unilateral anterior cerebral artery and the angle between A1 segment and A2 segment are important factors for the formation and development of ACoAA. The aneurysmal orientation of ACoAA is closely related to the morphological features of the A1 segment of the dominant anterior cerebral artery. The morphology of the A1 segment of anterior cerebral artery has an important effect on treatment and outcome of ACoAA.
