Percutaneous transluminal renal angioplasty in hypertension

The aim of our study was assess anatomical and functional results of renal artery angioplasty with and without stenting in 25 hypertensive patients (8 female and 16 male, 42.6 and 61.6 years old respectively) with significative renal artery stenosis (RAS) (atherosclerotic: 22; fibrodysplastic: 3). Eleven patients had simple angioplasty and 13 had stenting. The rate of angioplasty success was 96%. In the stent group, the anatomical result was better: 2% of residual stenosis versus 24% in the other group (p < 0.001). Restenosis occurred in 2 patients. Immediately after revascularisation arterial blood pressure decreased from 195/105 +/- to 150/85 +/- mmHg in-group without stent (p < 0.001) and from 190/100 to 145/85 mmHg in the group (p < 0.001). The value of serum creatinine concentration in patient with renal failure didn't change after revascularization.
