Summary: | To analyze the effect of percutaneous transluminal renal angioplasty (PTRA) in renovascular hypertension.
Twenty-three patients with renal artery stenosis and arterial hypertension underwent PTRA. There were 11 male and 12 female, 19 to 78 years old (45.8 +/- 17.41). In 20 lesions the diagnosis was atherosclerosis, in 7 fibromuscular dysplasia and in 1 Takayasu arteritis. Three patients underwent bilateral dilatation and 2 patients repeated the procedure due to restenosis. Two patients presented with acute renal failure and severe bilateral renal artery stenosis.
There were 21 technical success in 25 procedures. After 20 satisfactory dilatations, clinical success followed in 17 (100% of cases of fibromuscular dysplasia cases and 77% of atherosclerosis. The fall in diastolic arterial pressure after PTRA was statistical significant (p < 0.001). In two cases acute renal failure the renal function became normal after angioplasty. There were 2 complications and no death attributed to PTRA.
The method was effective and safe in the management of renovascular hypertension during the short-term follow-up. It was possible in two cases of acute renal failure to normalize renal function. |
