VARIATIONS IN ANTERIOR SEGMENT OF CIRCLE OF WILLIS IN HUMAN CADAVERS.

Dr. Shubhangi Yadav

Abstract :

 AIMS AND OBJECTIVE : A major part of ain is supplied by the anches of two internal carotid arteries and two verteal arteries. A significant anastomosis, the Circle of Willis exist between the carotid and verteal arterial systems. An understanding of the distribution of the arteries is very important.As the neurological signs depends on the site of lesion.

Material and methods: The study was conducted on 45 adult ain specimens of  both sexes in human cadavers.The collected specimens were preserved in 10% formalin.The Circle of Willis of each ain was dissected with care.

Results: Variations in anterior segment of  Circle of  Willis in ain specimens includes – duplicity, fenestration, trifurcation and absence of arteries.

Conclusion: Various diseases of  arteries of ain like cereo – vascular attack, aneurysm, haemorrhage etc. are related to the anatomic patterns of  the Circle of Willis.The knowledge of which is of considerable help to neurosurgeons.
