Cadaveric Study of Accessory/Aberrant Left Hepatic Artery From Left Gastric Artery - Embryological Basis & Its Clinical Significance

Aim: The present study aims at contributing to the existing information related to the incidence of origin of aberrant left hepatic artery from left gastric artery and its clinical significance. The information of branching patterns of arteries, their embryological basis and variations is important in various surgical and radiological procedures. Material and Methods: Fifty (50) embalmed adult human cadavers of both sexes were dissected for the study in the department of anatomy in Sri Siddhartha Medical College and other medical colleges in and around Bangalore. Results: Out of the 50 specimens, four specimens (8%) showed the presence of aberrant left hepatic artery arising from the left gastric artery and it was accessory type in all the four cases. Conclusions: A good knowledge about the embryological basis &variations in the branching pattern of left gastric artery is essential to reduce the complications and increase the success rate in surgical and interventional procedures in hepatobiliary region.
