Long-term results of surgical treatment of renovascular hypertension.

The authors analyse long-term results of surgical treatment of renovascular hypertension in 195 patients hospitalized at the Institute for Clinical and Experimental Medicine in Prague in 1971 to 1982. Significantly better results were attained in patients with dysplastic stenosis than in patients with sclerotic stenosis of renal arteries (86.45% vs. 56.33%). In view of this experience the authors stress the importance of most accurate diagnosis of the morphological basis of the stenosis. In patients with sclerotic stenosis, the probability of a favourable effect of surgical reconstruction on blood pressure is substantially smaller. Attention is drawn to the important successes attained with the use of percutaneous transluminal angioplasty, which has in recent years found considerably wide application precisely in the sphere of renal arteries.
