ABSTRACT
Objective:
to evaluate the use of percutaneous transluminal renal angioplasty (PTRA) in the treatment of renal vascular hypertension.Design:
sequential prospective PTRA treatment of severe arterial hypertension, screening by the captopril test, confirmed by renal arteriography, and the result evaluated by post-PTRA arteriography, blood pressure measurement and renal fucntion. Site Vascular Surgery, angioradiology sector, and Nephrology outpatients department of the Federal University of Sao Paulo - Paulista School of Medicine, Sao Paulo, Brazil, a tertiary health-care instittution.Participants:
PTRA was employed on 32 patients screened by clinical examination, captopril test and renal arteriography. Evaluation PTRA results were evaluated by the criteria of the Cooperative Study of Renovascular Hypertension.Results:
after PTRA the completion arteriography showed no renal stenosis in 24 patients (75 percent), residual stenosis (20-50 percent) in 3 (9.4 percent) and no change in 5 (15.6 percent). The blood pressure results were 3 patients (9.4 percent) were cured, 24 (75 percent) improved and 5 (15.6 percent) were unchanged. we observed normal renal function before and after PTRA in 25 patients (78 percent); altered pre- and improved post-PTRA in 2 (6.3 percent); post-PTRA remained unaltered in 2 (6.3 percent); and altered pre- and worsened post-PTRA in 3 (9.4 percent). Recurrence of stenosis occurred in one patient after 8 months.Conclusions:
PTRA is a convenient procedure, relatively safe and an effective complementary method of medical therapy for controlling renovascular hypertension.
