ANTERIOR CEREBRAL ARTERY, ANTERIOR COMMUNICATING ARTERY, POSTERIOR COMMUNICATING ARTERY, POSTERIOR CEREBRAL ARTERY-A RETROSPECTIVE STUDY

In the embryonic period, several developmental anomalies of the cerebral arteries are common. The knowledge of these anatomical variations of the cerebral arteries is important for effective treatment and surgeries. We have studied different patterns and variations of cerebral arteries in 70 cadavers, both foetal and adult, and have depicted our observations and conclusions. "Vascular diseases in general is the commonest cause of death all over India as well as most other countries. But the diseases of blood vessels of the brain which are more frequent causes of death and disability have not attracted as much public attention as the required."(1) Hence a study of vascular supply of brain and its variational anatomy will help in proper and through understanding and interpretations of infarction embolism, thrombosis and other connected problems through modern investigation methods ( Noninvasive techniques), MRI, MRA, CT and TCCD, etc. Hence, this work has been taken up, selecting the dead human foetuses and adult human cadavers.
