Abstract
The aneurysm arising from the posterior cerebral artery is relatively uncommon, and has been reported in 0.7- 2.2% of whole cerebral aneurysm. Moreover, only a few cases of the giant aneurysm over 2.5cm in diameter arising from the distal portion of the posterior cerebral artery have been reported. Neurologic complications may occur after surgical treatment of this aneurysm due to difficult surgical approach and neurovascular complexity around the brain stem. Authors experienced a case of the thrombosed giant aneurysm with approximately 2.7cm in diameter arising from the P2 segment of the left posterior cerebral artery. Complete removal of the thrombus in the aneurysmal sac and direct neck clipping was performed via left subtemporal approach.
