Coagulopathies in Horses with Colic

The most common coagulopathy in horses with colic is a hypercoagulable state associated with disseminated intravascular coagulation. The intensity of this coagulopathy depends on the severity and duration of the gastrointestinal lesion, with the ischemic and inflammatory problems and peritonitis being the most frequently affected by coagulopathies. Early initiation of prophylactic therapy significantly reduces the severe hypercoagulable state in horses with intestinal conditions which are recognized to be at high risk for disseminated intravascular coagulation. In addition to the systemic coagulopathy observed in horses with colic, a peritoneal coagulopathy independent from that occurring in blood has been observed, and its recognition and assessment may have clinical usefulness in the diagnosis of the gastrointestinal diseases and outcome. © 2009 Elsevier Inc.
