【 摘 要 】

Posterior cerebral artery (PCA),terminal branch of basilar artery join the posterior communicating artery to complete the circle of Willis. The morphological variations of posterior segment of the circle of Willis are much of importance in the diagnosis & treatment of different cerebrovascular diseases.In a series of anatomical dissections of the cerebral arterial territory in 30 cadaveric brain specimens,an important variation of the precommunicating segment of the posterior cerebral artery PI was found. In this variation, an embryonic derivation of the posterior cerebral artery from the internal carotid artery (ICA) known as foetal type posterior cerebral artery was seen. This type of variation may lead to the appearance and severity of syndromes of vascular insufficiency in adults.
