ABSTRACT:

Background: Anterior communicating artery, a short trunk connecting the anterior cerebral arteries is important in stabilizing blood flow by acting as collateral channel. The present study was conducted to note the variations in anterior communicating artery which may be one of the reason for formation of aneurysm.

Materials and Methods: Anterior communicating artery was observed for its number, course, length and variations in 50 adult embalmed cadaveric brains after injecting with latex solution.

Results: Duplication of anterior communicating artery was found in 4 specimens (8%) and it was absent in 2%. The course of ACoA was oblique in 54.2% and transverse in 45.8%. The length of ACoA was on an average of 2.82mm. The mean diameter of ACoA was 1.12mm. Fenestration of ACoA was seen in 4%.Median artery of corpus callosum was found in 1 specimen.

Conclusion: Congenital anomalies of the intracranial arteries predispose to the formation of aneurysms due to an increased haemodynamic stress. Knowing the length, course and diameter of ACoA is important as it may guide radiologists in interpretation and neurosurgeons in microsurgical procedures.

KEY WORDS: Anterior communicating artery, Aneurysm, Duplication, Fenestration.
