PURPOSE: @entity694 has historically been controlled by the use of localization procedures and surgery. Since our initial experience with superselective embolization of @entity694 , it has become our preferred method for the control of @entity360 . This follow-up study evaluates the Hartford Hospital experience using angiographic methods as the primary modality for the treatment of @entity694 . METHODS: From March 1993 to September 1999, 27 @entity1 who had angiographically visualized @entity548 underwent @entity1416 procedures. Diagnostic arteriography was performed in all @entity1 using digital subtraction imaging and selective contrast injections into the superior and inferior mesenteric arteries. Once the bleeding site was identified, superselective arteriogram and embolization was performed. @entity902 -fibered coils, Hilal coils, or @entity4832 particle emboli were then fluoroscopically guided into the bleeding vessel. A repeat arteriogram was performed to confirm occlusion and the absence of any collateral channels. RESULTS: All 27 @entity1 were initially controlled with @entity1416 ; 6 @entity1 rebled (22.2 percent), and 5 of these @entity1 required surgery. Two @entity1 demonstrated @entity63 (7.4 percent), one of which required surgical intervention. The other @entity1 was followed up by colonoscopy. There was no mortality in this study. CONCLUSION: Superselective embolization is effective in controlling @entity548 and is associated with a low rate of postembolization @entity63 . Our experience with angiography reinforces the paradigm shift from its use as a diagnostic tool to the primary method for the control of @entity694 . Because @entity1 have been followed up for as long as seven years, this approach remains effective for the long-term treatment of @entity694 .

The changing paradigm for the treatment of XXXX : superselective angiographic embolization.
