Cadaveric Study of Posterior Cerebral Artery
DR HASHMI INTKHAB C, DR JADHAV SHAILENDRA S
Posterior cerebral artery is terminal branch of the basilar artery and one of the impotent arteries of posterior circulation of the brain. Development of the arteries of posterior circulation is complex event leads to morphological variability in the arteries in post natal life. Posterior cerebral artery also shows three types of variations which are adult type, fetal type and transitional type. Present study was done to know the incidence of these variations. 31 specimens show bilateral adult type and 2 specimens shows bilateral fetal type. In remaining 7 specimens, 2 specimens show adult type on right side and fetal type on left side, 3 specimens shows fetal type on right and adult type on left side, 1 specimen show fetal type on right and transitional type on left side, while another 1 specimen shows transitional type on right and adult type on left side. Knowledge of this variability is required in neurosurgeons especially while performing neuroendoscopic procedures since the arterial network is very delicate in the region.
