Hepatic artery thrombosis occurs when a blood clot forms in the artery that provides blood flow to the liver. Hepatic artery thrombosis may occur as a complication after liver transplantation,[1] and represents the most common complication of liver transplantation.[2] Smoking tobacco increases the risk of hepatic artery thrombosis in people who have undergone liver transplantation.[3]
Hepatic artery thrombosis may cause severe elevations in serum aminotransferases, alanine transaminase (ALT) and aspartate transaminase (AST).[4] Often the AST is greater than the ALT.[4] Hepatic artery thrombosis is usually diagnosed with ultrasound with doppler, although it may be diagnosed using computed tomography (CT) or magnetic resonance imaging (MRI).
The treatment for recently developed or acute hepatic artery thrombosis include anticoagulant medications, fibrinolytic therapy to break up the blood clot, or surgical revascularization.[2] If acute hepatic artery thrombosis occurs after liver transplantation, then retransplantation with a new liver may be necessary.[2]
