Abstract

Objective　To investigate the anatomical features of variant hepatic artery so as to provide morphological data for clinical operation, such as related vascular imaging examination, surgery and interventional therapy.　Methods　Twenty-five adult corpses were dissected in the routine method. The branches of the proper hepatic artery and their distributions were traced along the common hepatic artery, and the distributions were studied.　Results　The variant rate of proper hepatic artery and its branches was 28%. Some variant branches beyond the Hitta classification were found in 2 cases, in which the right gastric artery was not found as expected on the right wall of the proper hepatic artery；it originated from the left wall and was distributed in the liver and stomach, and was called "hepatogastric artery (HGA)" in the literature. In one of the two specimens, a branch was found originating from the posterior wall of HGA and also distributed in the liver and stomach, which was thus called "hepatogastric accessory artery".　Conclusion　HGA originates from the left wall of the proper hepatic artery in two of the specimens, and is the main arterial source of the right side of the lesser curvature of the stomach, and has branches to nourish the liver and other parts of the stomach as well. This research contributes to the morphological data of the variant hepatic artery, and may give some guide to the related clinic operation.
