Renovascular disease is a complex disorder, most commonly caused by fibromuscular dysplasia and atherosclerotic diseases. It can be found in one of three forms: asymptomatic renal artery stenosis RAS , renovascular hypertension, and ischemic nephropathy. Particularly, the atherosclerotic form is a progressive disease that may lead to gradual and silent loss of renal function. Thus, early diagnosis of RAS is an important clinical objective since interventional therapy may improve or cure hypertension and preserve renal function. Screening for RAS is indicated in suspected renovascular hypertension or ischemic nephropathy, in order to identify patients in whom an endoluminal or surgical revascularization is advisable.

The aim of this study was to evaluate the utility of color-Doppler ultrasound CDUS in detecting haemodynamically significant in-stent restenosis in patients who underwent endoluminal renal artery revascularisation by stent deployment. Between January and December , 42 patients nine women and 33 men, age range 45—87 years treated by endovascular renal artery stenting were studied with CDUS.
Renal artery haemodynamics were evaluated to identify haemodynamically significant restenosis. Patients with CDUS signs of restenosis underwent angiography for a possible further revascularisation procedure. Of these 13, three did not undergo endoluminal renal artery revascularisation because renal ischaemia deterioration and irreversible renal circulation impairment.
In the remaining ten patients Restenoses were successfully treated by a repeat endovascular revascularisation procedure. Our results confirm the fundamental role of CDUS in the follow-up of patients after renal artery stenting. It enables early restenosis detection and evaluation of renovascular disease associated with renal artery stenosis. CDUS provides essential information for the subsequent clinical management of these patients. I pazienti con segni ECD di ristenosi sono stati sottoposti ad esame angiografico per eventuale ulteriore intervento di rivascolarizzazione.
Di questi, 3 non sono stati sottoposti ad angiografia per peggioramento della nefropatia ischemica ed irreversibile compromissione emodinamica del circolo renale.
Le restenosi sono state trattate con successo per via endovascolare. This is a preview of subscription content, log in to check access. Rent this article via DeepDyve.

Diagnosis of nephrovascular hypertension is important because prompt correction of renal artery stenosis R. Arteriography is currently the gold-standard method for confirming the location and nature of the stenotic lesion prior to corrective procedure. The use of color Doppler-spectral Doppler sonography in the screening of hypertensive patients has been proposed in light of its diagnostic accuracy, relatively low cost and safety. View PDF.
