Abstract

Objective: to evaluate and describe the prevalence of hepatic arterial variants seen at digital subtraction angiography.
Materials and methods: data were collected at Interventional Unit in Diagnostic Imaging department of Viet Duc hospital from
May 2015 to May 2016. 
Results: 300 cases underwent at least one visceral angiographic examination during the study period. 232 (77.3%)
cases had standard hepatic arterial anatomy. 14 (4.7%) cases had replaced left hepatic artery. 11 (3.7%) cases had replaced
right hepatic artery. 2 (0.7%) cases had variant anatomy involving replacement of both left hepatic artery and right hepatic artery. 16 (5.3%) cases had accessory left hepatic artery. 3 (1%) cases had accessory right hepatic artery. 1 (0.3%) case had both left and right accessory hepatic artery. 12 (4%) cases had replaced common hepatic artery. 3 (1%) cases had double hepatic artery. 1 case had replaced common hepatic artery and accessory left hepatic artery at the same time. 1 case had right hepatic artery arises from aorta and left hepatic artery arises from left gastric artery.
Conclusion: in this study the percent of standard hepatic artery is larger than previous published study while the percent of
cases had other variants of hepatic artery is smaller. In 2 cases, we saw uncommon variants which weren’t described in previous
study. However we didn’t see some other uncommon variants which were described in other study.
