[Treatment of renal artery stenosis by percutaneous transluminal angioplasty (PTA) (author's transl)].

The preliminary results of treatment of the stenosis of renal artery by the transluminal percutaneous angioplasty (PTA) were presented. 6 patients were treated by the Gruntzig technique, 4 of the 5 patients probably having renovascular hypertension were returned to normal tension 2 to 5 months after treatment. The 6th patient had hypertension with severe renal insufficiency. The PTA was performed for the purpose of the inhibition of progressing renal insufficiency. This patient was stabilized. This preliminary experience show great interest of this technique.
