[Percutaneous transluminal catheter dilatation of kidney artery stenoses in patients with renovascular hypertension]
Abstract
14 patients with severe hypertension showed unilateral (7) or bilateral (6) stenoses of renal artery due to arteriosclerosis (12) or fibromuscular hyperplasia (7); one stenosis appeared after renal transplantation. Successful application of percutaneous transluminal angioplasty of renal artery was performed in 14 stenoses. 4 of 10 patients showed normal values of blood-pressure, in 4 patients blood-pressure was improved, in 2 patients hypertension remained unchanged. The patients were observed 1 to 23 months after dilatation; antihypertensive drugs were necessary in all cases, but could be reduced. The effectiveness of the procedure was demonstrated by renal arteriogram and determination of pre- and poststenotic blood-pressure values.
