Arterial phase CT images showed a prominent segmental branch of the right hepatic artery with a fistulous track communicating with the right hepatic vein (Figures 1-2).
Angiographic images show replaced right hepatic artery originating from the SMA (white arrow). The segmental branches arising from the right hepatic artery communicate with the fistulous tracks (black arrows) draining into the hepatic vein.

Selective angiogram showed two prominent hepatic artery segmental branches leading to the lacerated liver parenchyma with early filling of the right hepatic vein suggesting post-traumatic arteriovenous fistulae (Figure 3).
Status post-deployment of coils in both the fistulous tracks. Angiogram shows (white arrows) completely occluded AV fistulous tracks with good arborization of hepatic arterial branches within the hepatic parenchyma.
