Figure 1. Case 1. (a) Coeliac axis angiogram showing occlusion of the proximal portion of the right hepatic artery (arrow). Collateral blood flow into the peripheral branches of the hepatic artery through the peribiliary arterial plexus (arrowheads) arising from the gastroduodenal artery is seen. (b) coeliac axis angiogram after Palmaz stent placement (arrow) showing recanalization of the right hepatic artery and disappearance of the collateral circulation. (c) Angiogram via the implantable port shows that the blood supply was greatly improved throughout the liver.
