Hemostatic profiles (prothrombin time, activated partial thromboplastin time, fibrinogen concentration, fibrin degradation product concentration, platelet count, and antithrombin III activity) were acquired prospectively in 20 dogs with a diagnosis of gastric dilatation‐volvulus. Eighteen dogs had abnormal results of one or more hemostatic test, including eight dogs that had hemostatic profiles consistent with a diagnosis of disseminated intravascular coagulation. During surgery, or at necropsy, the dogs' stomachs were evaluated for gross abnormalities, and lesions were graded subjectively as mild, moderate, or severe. Eight dogs had mild gastric lesions, five had moderate lesions, and seven had severe changes indicating gastric necrosis. Seventy percent (7/10) of the dogs with two to six abnormal hemostatic test results had gastric necrosis, whereas none of the 10 dogs with no or one abnormality had gastric necrosis (p < .001). A multiple linear regression equation, based on fibrin degradation product concentration, activated partial thromboplastin time, and antithrombin III activity was derived to predict gastric necrosis. This equation correctly identified gastric necrosis with 86% sensitivity, 100% specificity, 100% positive predictive value, and 93% negative predictive value.
