Ischemic cholangiopathy is focal damage to the biliary tree due to disrupted flow from the hepatic artery via the peribiliary arterial plexus.
(See also Overview of Vascular Disorders of the Liver.)
Common causes of ischemic cholangiopathy include
Bile duct injury (ischemic necrosis) results, causing cholestatis, cholangitis, or biliary strictures (often multiple). Ischemic cholangiopathy most commonly occurs in people who have had a liver transplant.
Symptoms (eg, pruritus, dark urine, pale stools) and results of laboratory tests, and imaging studies may indicate cholestasis.
Diagnosis
The diagnosis is suspected when cholestasis is evident in patients at risk, particularly after liver transplantation. Ultrasonography is the first-line diagnostic imaging test for cholestasis, but most patients require magnetic resonance cholangiopancreatography, ERCP, or both to rule out other causes such as cholelithiasis or cholangiocarcinoma (see Imaging Tests of the Liver and Gallbladder).
