Vascular complications of hepatic artery after transcatheter arterial chemoembolization in patients with hepatocellular carcinoma.

Objective: The purpose of this article is to review the angiographic changes, development of collaterals, and possible complications after transcatheter arterial chemoembolization (TACE) in hepatocellular carcinoma (HCC).
Conclusion: Extrahepatic collateral arteries can supply the tumor after repeated TACE. Knowledge of hepatic artery changes can help in repeated TACE procedures and reduce TACE time. Appreciation of the complications and collaterals may improve the outcome of patients with HCC.
