- Does Variant Hepatic Artery Anatomy in a Liver Transplant Recipient Increase the Risk of Hepatic Artery Complications After Transplantation?


TABLE 1 Cause of End-Stage Liver Disease in 84 Liver Transplant Recipients

Cause
 No.
Hepatitis C 16 (4)
Alcoholic liver disease 12
Hepatitis C and alcoholic liver disease 11 (3)
Primary sclerosing cholangitis 9
Primary biliary cirrhosis 6 (1)
Nonalcoholic steatohepatitis 6 (1)
Hemochromatosis 5 (1)
Hepatitis B 4 (1)
Alpha1-antitrypsin deficiency 4
Hepatitis B and hepatitis C 3
Cryptogenic cirrhosis 3
Autoimmune hepatitis 2

Note.—Data are numbers of patients. Parentheses indicate number of patients with hepatocellular carcinoma.

a Erythropoietic protoporphyria, polycystic liver disease, and Wilson's disease.

Accessory RHA from GDA and accessory LHA from LGA 1 1.2
Accessory LHA from LGA 8 9.5

Note.—LHA = left hepatic artery, LGA = left gastric artery, RHA = right hepatic artery, SMA = superior mesenteric artery, GDA = gastroduodenal artery, CHA = common hepatic artery.

a Right and left hepatic arteries arise normally from a single proper hepatic artery, which in turn arises from a single common hepatic artery, which arises normally from celiac artery.

Note.—Data are rates of hepatic artery complications (number of complications/total number of patients in each category). One of 15 donors with variant hepatic artery was excluded because patient underwent aortic jump graft reconstruction. Rate of hepatic artery complications in donor variant hepatic artery was not statistically significant (p = 0.330).
