title: [Roentgenoendovascular dilatation of the renal arteries in the treatment of vasorenal hypertension].
abstract: The possibilities of the use of roentgenoendovascular dilatation of the renal artery were studied in 57 patients with stenosis of the renal artery and vasorenal hypertension. The authors managed to perform the manipulation in 48 patients. Occlusion of the renal artery, pronounced atherosclerosis of the iliac and axillary arteries, coarctation of the aorta were the causes of failure. In 52.6% of the patients, the "residue" of stenosis was less than 30% of the normal arterial lumen, in 31.6%--30-50%, in the remaining patients, the dilatation has failed. Stable normotension was achieved in 39.5%, the state improved in 50% of the patients. The absence of hypotensive effect for the first 6 mos after the operation was caused by recurrency of the dilated artery stenosis, which resulted from the improper choice of a balloon catheter. The diameter of such a catheter should be 100-110% of a width of the renal arterial lumen proximally to stenosis. The later recurrency of hypertension was caused by the development of the stenosis of the artery of the contralateral kidney.
