To explore the diagnostic value and effects of digital subtraction angiography (DSA) for acute gastrointestinal hemorrhage.

Twenty-five patients of gastrointestinal hemorrhage of unknown reasons were examined by DSA , and the positive ones were treated by the gelfoam embolization combined with pituitrin infusion.

Eighteen of the twenty-five patients showed positive signs, taking up the rate of 72%. Ten patients, directly found the petechiae, were treated by gelfoam embolization combined with pituitrin infusion embolization. Eight cases of suspected petechiae were given pituitrin infusion treatment. Six patients were hemorrhage of gastroduodenal, 9 of the rest of small intestine, 3 of colon and rectum. 5 cases were caused by the hemorrhage of ulcer disease, 2 by neoplastic lesions, 1 by diverticulum, 4 by vascular lesions, and 6 by anastomotic hemorrhage. Postoperative hemorrhage was found in 3 patients. Four cases were still given conservative medical treatment, and 6 of surgery.

DSA, an effective and minimally invasive interventional treatment, is worth generalizing on clinic.
