Presentation
Bleeding gastric ulcer treated with endoclip. History of liver trauma 2 years prior.
Patient Data
Saccular pseudoaneurysm with partial thrombosis of the proximal right hepatic artery (diameter 4.5 cm approximately).
Cavernoma in segment 8 of the liver.
Hepatic lacerations (segments 6 and 7) with hemoperitoneum.
In the arterial phase, there is a perfusion defect in the right lobe of the liver with flow interruption in the right branch of the hepatic artery which is surrounded by a hematoma.
Cavernoma in segment 8 of the liver.
Case Discussion
Hepatic artery aneurysms are rare. Rarer are those associated with a venous or biliary fistula. They tend to be saccular and multiple. Causes include infection, arteriosclerosis, trauma and vasculitis. Untreated aneurysms can lead to rupture into the common bile duct, peritoneum, or nearby hollow viscera.
