Nierenarterienstenose : Aktueller Stand (Leitthema)

摘要: Uncritical treatment of renal artery stenosis has led to disappointing results. In five randomized studies comparing angioplasty with optimal medicinal only small or no effects on function and blood pressure were found. Subgroups patients a high likelihood positive response have be identified the help controlled trials. Factors which could possibly an effect outcome are degree stenosis, method (angioplasty without stents, use emboli protection devices), contrast medium toxicity atheroembolisms underlying parenchymal disease, can prevent success despite successful correction stenosis. Doppler sonographic measurement resistance index captopril scintigraphy published methods may classify into responders non-responders. The prognostic value should evaluated in studies.
