Traumatic hepatic arteriohepatic venous fistula managed with selective coil embolization: a case report.

Hepatic arterioportal fistulae are frequent vascular complications due to neoplasm, trauma and iatrogenic injury. On the other hand, fistulae between the hepatic arteries and hepatic veins (arteriohepatic venous fistula) are rare. We report the case of a 45-year-old male who suffered from a blunt abdominal trauma with abdominal distension. Initial cross-sectional imaging revealed laceration of the right lobe of liver with an arteriovenous fistula and hemoperitoneum. The diagnosis of arteriohepatic venous fistulae was confirmed on digital subtraction angiography (DSA) and treated angiographically with superselective coil embolization. Post-embolization angiogram showed complete occlusion of arteriovenous fistulae. We emphasis on the management part of the fistulae and endovascular treatment.
