Introduction: Anterior cerebral artery is one of the terminal branches of internal carotid artery below the anterior perforated substance. Cerebral artery occlusion may leads to infarction in brain tissue. The occlusion is caused by stenosis, embolism or rupture of arteries. Cerebrovascular accidents which are the 3rd leading cause of morbidity and death in United States have attracted the attention of many scientists.
Materials and Methods: Study sample 50 well formalin preserved brain from cadavers in dissection hall of MGMs Medical College in year of June 2012 to December 2013. Length is measured by thread and diameter measured by venire caliper.
Results: The origin and course of anterior cerebral artery in all brains were same and 42 brains the size of Anterior cerebral artery (ACA) was equal. In 8 brains they were unequal size.
Discussion and Conclusion: Present study was undertaken in order to determine anatomical variations in anterior cerebral artery. The need for dimensional data for variation in morphology of vessels is expressed by neurosurgeons and radiologists as well as researches but no comprehensive measurements have been published, especially the Indian data. In anterior cerebral arteries diameter on right is 2.1 mm and on left 2.4 mm which was smaller than those of previous studies.
In present study the length of right 1.3 cm and left 1.2 cm which was less compared to other studies.
