Core Tip
Core Tip: Hepatic ischemia occurs after hepatic arterial occlusion with concomitant injury to collaterals, most importantly the peribiliary vascular plexus. This case of combined bile duct and right hepatic artery injury demonstrates that regional differences in bile color correlate with the extent of segmental hepatic ischemia. Darker, more concentrated bile originated from more ischemic areas, whereas lighter bile indicated preserved perfusion. Changes in bile color, although not studied extensively in recent years, might reflect underlying alterations in bile composition. These macroscopic changes provide a simple, real-time indicator of hepatobiliary functional impairment and offer interesting insights into the pathophysiology of ischemic cholestasis.
