PURPOSE: Evaluation of the handling, technical success rate, and six-months patency rate of a new, premounted balloon-expandable stent in @entity2791 . MATERIAL AND METHODS: In a prospective study, 27 @entity2791 in 20 @entity1 were primarily treated with the new "Renal Bridge Stent" (Medtronic AVE, D  sseldorf). All @entity1 had a history of @entity101 and 8 @entity1 had @entity8 . The handling and visibility of the stent was scored on a three grade scale by the operators. Follow-up angiography including intra-arterial trans-stenotic pressure measurements was performed in 23 out of 27 stenoses (17 @entity1 ). RESULTS: Handling and visibility were scored as good by all operators. 26 of 27 stenoses were treated with technical success by implantation of 28 stents. The mean degree of @entity850 was reduced from 74.2% to less than 5%. At 6 months, 8 stents out of 23 (35%) showed a significant in-stent @entity850 ( @entity850 degree > 50% and intra-arterial pressure gradient > 10 mmHg). The @entity850 rates were 63% using 5-mm stents, 30% using 6-mm stents, and 0% using 7-mm stents. CONCLUSION: Endovascular treatment of @entity2791 with the used stent is safe and effective. The new stent shows a good handling and visibility. The high rate of in-stent stenoses might be explained by the rigid follow-up protocol including angiography, trans-stenotic pressure measurements, and the high number of 5-mm vessels in our study.
