摘要: Duplex ultrasound examination of the renal arteries is an excellent screening test for presence significant RAS. It important to recognize that each technician and physician must validate his or her results against gold standard-arteriography. Currently we are able differentiate less than 60% stenosis from greater detect totally occluded arteries. In near future hope be further subdivide group in a manner similar what has been done with carotid artery duplex scanning. The noninvasive nature scanning ideal patient elevated serum creatinine whom wants determine, high degree likelihood, whether disease contributing azotemia. Accessory problem best series reported, sensitivity was only 67% but specificity 100%. Identification accessory will improve as equipment improves ultrasonographer becomes more experienced. useful following patients after PTRA, stents, bypass surgery document initial patency vessel follow long-term these vessels. also way natural history disease.
