Abstract:
Objective To determine the prevalence of renal artery stenosis (RAS) and the efficacy of percutaneous transluminal renal angioplasty (PTRA) and stenting in patients with documented coronary artery disease.Methods Selective renal artery angiography or abdominal digital subtraction angiography was performed immediately after coronary angiography to detect and quantify RAS in 200 consecutive patients with known or suspected coronary artery disease. Eight severe stenotic renal arteries in 7 patients were treated with PTRA and stenting. All the lesions are considered to be atherosclerotic. Results RAS (defined as ≥50% diameter stenosis) was detected in 21 of 200 patients (10.5%) and 19 of 99 patients with coronary artery disease (19.2%) who had at least one coronary artery of ≥50% diameter stenosis. Procedure success rate was 100% in the 7 patients received PTRA and stenting. Blood pressure control improved in 74.1% patients with hypertension. Angiographic follow up was done in 3 patients in 3 to 9 months and no restenosis was found in the vessels.Conclusions It is necessary to routinely perform RAS for the patients with coronary artery discase undergoing coronary angiography to identify RAS, especially in those associated with hypertension, so as to diagnose and treat RAS in early stage. PTRA and stenting carries high success rate and appears to be an effective and safe treatment for RAS.
