Combined Sub-temporal and Pterional Exposure for Clipping of Posterior Cerebral Artery Aneurysm

Posterior cerebral aneurysms are rare posterior circulation aneurysms. Clinical presentation can be varied from life-threatening subarachnoid hemorrhage to mass effect on adjacent structures. Due to their complex anatomical location, microsurgical clipping is not without challenges. Several approaches have been described based on the location of the aneurysm in relation to the segment of the posterior cerebral artery (PCA). We describe a combined approach for surgical clipping of a postcommunicating anterior segment PCA aneurysm.
