ANATOMICAL VARIATION IN ORIGIN OF CENTRAL BRANCHES OF THE MIDDLE CEREBRAL ARTERY
Journal Title: JOURNAL OF ANATOMICAL SCIENCES - Year 2017, Vol 25, Issue 2
Abstract
Introduction: The knowledge of origin of the central branches of the middle cerebral artery (MCA) have been of great significance for the radiologists and neurosurgeons dealing with cerebrovascular pathological conditions. A number of variations have been earlier reported for the course of MCA and its branches. The present study was performed to observe whether there are any further variations existing other than those reported earlier. Material & Methods: The study was performed on 60 (38 males and 22 females) formalin fixed brains, obtained from the Department of Anatomy and Forensic Medicine, Institute of Medical Sciences, Banaras Hindu University, Varanasi. The brain tissue was dissected and MCA in each brain was picked up and observed for the branching pattern under the dissecting microscope. Results: The study revealed that the central branches that originated from the M1 segment of MCA were either single or double or multiple in number, instead of two groups as described earlier. In few cases, these central branches originated not only from the M1 segment, but also from other artery of the Circle of Willis. After their origin, all the branches travelled through anterior perforating substance to reach the basal area of the sub cortical zone. Conclusion: The present study reveals that there exist variations in the origin and course of MCA and its branches in addition to those reported previously.
