Distal Posterior Cerebral Artery Aneurysms: Report of 2 Cases

ABSTRACT

Two cases of aneurysms in the P3 segment of the posterior cerebral artery are described. These were managed by the subtemporal approach. One giant aneurysm in a 47-year-old male was treated by clipping the afferent artery, and the other small saccular aneurysm in a 41-year-old female was treated by clipping the aneurysmal neck. There were no complications after surgery, and the patients were discharged without neurological deficit. The operative approaches and procedures are also discussed in relation to the anatomy of posterior cerebral artery aneurysms.
