Catheter-dilatation (percutaneous Transluminal Angioplasty=PTA) of @entity2791 can be applied successfully and without major risk even in @entity1 with high operative risks. Therefore, the indication for the diagnostic evaluation of @entity2791 should be expanded to all @entity1 suspected to have @entity2792 . Excretory urography combined with angiotomography offers the possibility to visualize the renal arteries and to either detect or exclude @entity2791 . In the first part results of this procedure are presented. The bolus injection have been carried out on 415 @entity1 without any serious side-effects. Using angiotomography 49 @entity2791 , 1 @entity439 and 1 AV @entity292 could be detected. Catheter-angiograms, angiotomograms and conventional rapid sequence urograms were compared in 91 @entity1 . For angiotomography a sensitivity for the presence of @entity2791 of 93% and a specifity for the absence of @entity2791 of 99% can be attained. In the second part, the results of PTA of @entity2791 in 35 @entity1 are described. PTA was technically successful in 29 @entity1 (83%). Three clinically silent complications are reported. In a mean follow-up period of 8,2-months, @entity101 was normalized in 13 (45%) and improved in 10 (34%) @entity1 . @entity177 could be normalized in 7 out of 11 @entity1 . These results make PTA the method of choice in treating @entity2792 . Only if this method is not applicable or technically not feasible, is the alternative for treatment surgical revascularization or conservative antihypertensive therapy.
