MORPHOMETRIC STUDY OF ANTERIOR COMMUNICATING ARTERY IN HUMAN BRAINS IN UTTAR PRADESH : A CADAVERIC STUDY

Abstract

Background: This study is important for radiologists and neurosurgeons as the anterior communicating artery is an important artery of blood supply of the brain and is also a part of the circle of Willis. It connects two anterior cerebral arteries across the commencement of longitudinal fissure. Different morphometric parameters like the direction of origin, intracranial course, diameter of the artery and number of arteries are studied in this study. Materials and Methods: A retrospective study was conducted over more than 2 years in the anatomy department, Subharti Medical College, Swami Vivekanand Subharti University, Meerut, Uttar Pradesh. A study was conducted on 50 human cadaveric brains, which were removed from the cadavers used for teaching purposes for undergraduate and postgraduate students. Dissection followed by measurement and pictorial documentation of the anterior communicating artery was done in all 50 specimens. Results: Of 50 cadaveric adult brains, 04% show an absent anterior communicating artery. 60% have an oblique course, and 36% have a horizontal course. 2.78 mm was the average length observed, and 1.08 mm was the average diameter of the artery. No extra pair of arteries was seen in any of the specimens. Conclusion: From this study, we can conclude that morphometrics of the anterior communicating artery is not rare. The artery's oblique and horizontal course was observed in many specimens along. In a few cadaveric brains, the anterior communicating artery was absent. This morphometrics of the anterior communicating artery is significant for neurosurgeons and radiologists.
