Contrast-enhanced arterial-phase computed tomography (a) in the coronal plane showing significant luminal narrowing of the right hepatic artery (black arrow) with inferior tenting. Axial computed tomography (b) showing proximal right hepatic artery lying in the posterior wall of hepatico-duodenostomy anastomosis (white arrow). Right hepatic artery selective angiogram (c) showing the luminal narrowing of right hepatic artery with active contrast extravasation (dashed arrow) into the lumen of the duodenum. Post coil (dashed black arrow) embolization (d) no extravasation and filling of the distal right hepatic artery through collateral branches (double black arrow)

After hemodynamic stabilization, CT angiography with abdomen was performed which showed luminal contour irregularities in the proximal right hepatic artery (RHA) and its branch [Figure 1a]. In addition, the proximal part of RHA is seen in the posterior wall of HD anastomosis [Figure 1b]. The selective angiogram of the celiac axis at that time revealed focal inferior wall defect in RHA with definite extravasation of contrast [Figure 1c]. Check angiogram from hepatic artery proper showed no contrast extravasation with the collaterals filling distal part of the RHA [Figure 1d].
