[Renal artery occlusion: percutaneous revascularization].

The value of percutaneous revascularization of acute or chronic occluded renal arteries is demonstrated in 9 cases. Recanalization and dilatation was technically successful in 6 patients. The authors stress the importance of anatomo-radiologic criterion for successful recanalization. This technic is an attractive alternative to surgery specially in short occlusion.
