Common bile duct necrosis after cardiac catheterization

Abstract

A case of necrosis of the entire extrahepatic biliary tract after cardiac catheterization is presented. The axial blood supply to these structures makes them susceptible to ischemic injury.

Hepatic Artery Occlusion and Ischemic Cholangiopathy

“…Conditions associated with definite ischemic cholangiopathy include diseases in which primary lesions of the blood vessels supplying the bile ducts have been demonstrated. This group includes liver transplantation [11][12][13][14][15], hepatic arterial [16][17][18][19][20], acquired immune deficiency syndrome (AIDS) [21][22][23][24][25][26], hereditary hemorrhagic telangiectasia [27][28][29], radiotherapy on the main bile duct area [30,31], polyarteritis nodosa [32][33][34], and arteriosclerosis associated with cholesterol-crystal embolism [35][36][37]. The ischemic process of AIDS-related cholangiopathy is supported by the observation of CMV inclusions in arterioles close to bile ducts, which may induce vasculitis.…”
