Abstract
Purpose: To analyse the causes of coagulopathy and determine the effect of embolotherapy on acute gastroin-testinal(GI) bleeding coexisting with coagulopathy. Materials and Methods: Between June 1991 and December 1998, 29 patients with acute GI bleeding (M:F =21:8, mean age, 57.8 years) underwent percutaneous embolotherapy and immediate cessation of bleeding was confirmed. The patients were divided into two groups: control (n =16) and those with coagulopathy (n =13), group membership being determined according to the criteria of >±2SD of normal prothrombin time (PT) and activated partial thromboplastin time (aPTT) ( PT >23 seconds, aPTT >40 seconds) at the time at which embolization was requested. Embolotherapy was, defined as clinically successful, if the patient was stable for at least three days, without bleeding, after technically successful embolization. The clinical success rate of embolization and the mortality rate were compared between the two groups, and the causes of coagulopathy sta-tistically analysed. Results: The clinical success rate of embolization was 75% (n =12) in the control group, compared with 38.5% (n =5) in the coagulopathic group (p
