Concurrent Hepatic Artery and Portal Vein Thrombosis after Orthotopic Liver Transplantation with Preserved Allografts
Axial contrast enhanced CT scan image (a) reveals right-sided intrahepatic portal vein thrombosis (arrowheads). Thrombus (arrowhead) extends into main portal vein on more caudal image (b). Subtracted common hepatic arteriogram (a) demonstrates chronic proper hepatic artery occlusion with transplant liver perfusion (black arrowheads) via mature pancreaticoduodenal collateral vessels (white arrowheads). Black and white arrows delineate common hepatic artery and gastroduodenal artery, respectively. Selective gastroduodenal arteriogram (b) better demonstrates mature pancreaticoduodenal collateral vessels (white arrowheads), which result in transplant liver perfusion (black arrowheads).
