OBJECTIVE: We evaluated therapeutic microcoil embolization in a group of @entity1 with severe @entity548 . MATERIALS AND METHODS: Twenty-seven @entity1 with severe @entity694 due to @entity66 (n = 19), @entity2817 (n = 6), cecal @entity1066 (n = 1), or unknown cause (n = 1) underwent attempted microcoil embolization (n = 25). Microcatheters were used in all procedures, and embolization was performed at the level of the vasa recta or the marginal artery of Drummond. Branches of the superior mesenteric artery were embolized in 12 @entity1 , branches of the inferior mesenteric artery were embolized in 12 @entity1 , and branches of both the superior and inferior mesenteric arteries were embolized in one @entity1 . RESULTS: Technical success was achieved in 93% (25/27) of the procedures. However, immediate hemostasis occurred in 96% (26/27) of @entity1 because in one failed procedure, an occlusive dissection of the inferior mesenteric artery arrested bleeding. Three @entity1 rebled within 24 hr. One @entity1 was treated with endoscopic cauterization, and two @entity1 underwent right hemicolectomy. One @entity1 who underwent right hemicolectomy for rebleeding had ischemic changes found on pathologic analysis of the resected specimen, and a second @entity1 who underwent embolization of branches of the superior and inferior mesenteric arteries developed @entity1188 requiring left hemicolectomy. Prolonged clinical success occurred in 81% (22/27) of @entity1 . CONCLUSION: Therapeutic microcoil embolization for severe @entity548 is an effective and well-tolerated procedure.
