Dysfibrinogenemia in obstructive liver disease.

Acquired dysfibrinogenemia was documented in a 4-year-old child with obstructive jaundice of 1-month duration, secondary to a choledochal cyst involving the distal common bile duct. It was characterized by decreased thrombin coagulable protein with elevated immunoassayable fibrinogen resulting in abnormal thrombin and reptilase times. The liver morphology was compatible with extrahepatic obstruction, without evidence of cirrhosis or hepatocyte abnormality. All the coagulation abnormalities promptly resolved after surgical correction of the obstruction. Dysfibrinogenemia has been associated with serious liver disease in adults, including tumors, chronic active hepatitis, and cirrhosis, but never with isolated obstructive jaundice. This report documents a case of acquired dysfibrinogenemia due to extra-hepatic biliary obstruction and also emphasizes the importance of the consideration of this disorder in coagulation abnormalities associated with hepatobiliary disease.
