[The diagnostic value of digital subtraction angiography in detecting small intestinal bleeding].

To determine the diagnostic value of digital subtraction angiography (DSA) in detecting small intestinal bleeding.DSA was performed in 39 patients with suspected small intestinal bleeding. The sensitivity, specificity and accuracy of DSA were evaluated in the 25 patients who accepted surgical treatment.Among the 39 patients, 33 came out with positive in DSA. Eight patients were given interventional embolization successfully. The sensitivity, specificity and accuracy of DSA in detecting small intestinal bleeding were 91.7%, 100% and 92% respectively. The pathological results confirmed 77.3% of etiological diagnosis by DSA.DSA is an effective method for detecting small intestinal hemorrhage. The accurate diagnosis can guide the intervention with embolization.
