Right hepatic artery (RHA) vasculobiliary injury with collateral flow from left hepatic artery and atrophy of right liver. (A) Computed tomography scan of liver shortly after injury. The arterial phase shows no filling of right liver. (B) Arteriogram performed 2 years later. Abundant arterial collaterals extend from the left hepatic artery to the RHA along the hilar plexus (white arrowhead). The clip which occluded the RHA is also seen (black arrowhead). The arterial pattern of the right liver shows crowding (black arrows) indicative of atrophy of the right liver, whereas the arterial pattern of the left liver shows elongation and spreading characteristic of hypertrophy of the left liver.
