[Iatrogenic aneurysm of the hepatic artery. Treatment by percutaneous injection of thrombin and selective arterial embolization].

One case of hemobilia, revealing a right hepatic aneurysm, following a hepatic biopsy for active chronic hepatitis B, is reported. The diagnosis established by computed tomography and arteriography. Because of chronic hepatitis and the high localization of the aneurysm, surgery was not performed. A direct percutaneous thrombin injection was performed, owing to the fact that arterial catheterization was unsuccessful, and was followed by a decrease in volume of the aneurysm, but definitive recovery was achieved secondarily by arterial embolization (coil). This case illustrates the therapeutic alternative biopsy in intrahepatic arterial aneurysm treatment.
