The objective of this study was to assess the utility of colour-Doppler ultrasound (CDUS) in the investigation of patients with hypertension and nephropathy and to determine the association between haemodynamically significant stenoses of the renal arteries and abdominal aorta aneurysms (AAA). Between January 2000 and December 2004, 467 patients (205 women and 262 men, age range 20–96 years) with hypertension and chronic renal failure were referred to us for CDUS evaluation of renal morphology and haemodynamics and identification of haemodynamically significant stenoses of the renal arteries. Of the 467 patients examined by CDUS, 159 (34%) showed no signs of renal artery stenosis (RAS) or nephropathy and were therefore started on medical therapy. The remaining 308 (66%) exhibited signs of haemodynamically significant stenoses of the renal arteries or of nephropathy. AAA was identified in 19 of the 333 patients (5.7%) without haemodynamically significant renal artery stenoses and in 15 of the 134 patients (11.2%) with renal artery stenoses. Our results confirm the fundamental role of CDUS in the management of patients with suspected or known renovascular disease. The information provided by CDUS on renal haemodynamics is fundamental for a correct clinical approach. [ABSTRACT FROM AUTHOR] |
