Total of 82 procedures were done for patients with acute lower GI bleed. 26 patients had a rebleeding episode after mesenteric angiography. Of the 26 patients, 15 had negative prior mesenteric angiograms while 9 were positive cases. The results are summarized in the table. Rebleed after mesenteric angiograms in our study was 32% (26/82). The most common secondary intervention was surgery and endoscopy with diverticulosis and hemorrhoids being the most common underlying etiologies.
