[Percutaneous recanalization of renal arterial occlusion. Apropos of a case].

Percutaneous recanalization of a left occluded renal artery has been performed 10 days after percutaneous transluminal angioplasty of a controlateral renal stenosis. Improvement of the renal function is keeping normal 8 months after, although hypertension control is not very well. 26 case-reports have been found. These preliminary results are encouraging and suggest that this technique should be used against severe hypertension, especially if the kidney is functionnaly solitary, to avoid dialysis in patients with increased operative risk.
