[Transluminal angioplasty of the renal artery for renovascular hypertension (author's transl)].

The authors report an interesting case of dilatation of renal artery stenosis by inflation of the balloon of a catheter engaged in the stenosed arterial lumen inserted percutaneously under arteriographic control. The patient's hypertension responded within a few hours and plasma renin levels in the systemic circulation became normal within a few days. This result was stable at 2 months. In the opinion of the authors, this technique of percutaneous transluminal angioplasty, initially used for arterial obstructions of the lower limbs, carotid and coronary obstructions, should find a wide field of application in the area of renovascular hypertension.
