We report our experience with duplex ultrasound in young @entity1 with @entity2791 ( @entity2791 ) or @entity2500 ( @entity2500 ) before and after surgery (1995 and 2009). Of 36 @entity1 (mean age: 13      7  y), 21 had @entity2791 and 15 had @entity2500 . For @entity1 with @entity2791 , the Vmax in the affected artery was 350      111  cm/s before surgery and 145      55  cm/s after surgery. The resistance index was 0.46      0.1 in the post-stenotic kidney and increased to 0.60      0.08 after revascularization. Determination of the flow profile in the iliac artery revealed triphasic flow. In individuals with @entity2500 , Vmax in the aorta was 323      98 and the resistance index in both kidneys was low, even in the absence of @entity2791 . The flow profile in the iliac arteries was monophasic before surgery and became triphasic after surgery. Duplex ultrasound is useful for the evaluation of @entity1 and young adults both pre- and post-surgery. Duplex ultrasound criteria for @entity2791 in adults appear to be applicable in @entity1 and young adults also. The diagnostic evaluation of suspected @entity8 should include assessment of the aorta and the flow profile in the iliac arteries, as this could help differentiate between aortic and isolated @entity2791 .
