Abstract

Background and Aim. Anterior cerebral artery, one of the terminal branches of the internal carotid artery is an important vessel taking part in the formation of circle of Willis. It supplies a large part of the medial surface of the cerebral hemisphere containing the areas of motor and somatosensory cortices of the lower limb. Aim of this study was to study the morphometry of A1 segment of the anterior cerebral artery. Materials and Methods. 93 formalin fixed brain specimen of either sex and of Indian origin were studied. The mean length, mean external diameter & the anomalies present in A1 segment of the vessel were studied in detail & photographed. Results. The mean length of A1 segment of the vessel was 14.49±0.28 mm and 14.22±0.22 mm on right and left side respectively. The mean external diameter of the vessel on right and left side was 2.12±0.07 mm and 2.32±0.06 mm respectively. Narrowing, aneurysm formation, buttonhole formation and median anterior cerebral artery were the anomalies seen with an occurrence of 15.05%, 5.37%, 3.22% and 12.9%, respectively. The above anomalies did not have any sex or side predilection. Conclusion. Knowledge of morphometry of the vessel will be of use to neurosurgeons while performing the shunt operation, in assessing the feasibility of such operations and in the choice of patients. From this study we infer that the morphometry of anterior cerebral artery varies in different population and that the neurosurgeons operating should have a thorough knowledge of the possible variations.
