OSTIAL STENOSIS OF THE RENAL-ARTERY - RES ULTS OF SURGERY

Surgery and percutaneous balloon are two contrasting methods for the t reatment of renal artery stenosis. Surgical revascularizations offer e xcellent long term results with a 70 % to 90 % five year patency rate wherever the location of the lesion on the renal artery. Long term res ults of transluminal angioplasty are strongly correlated with the anat omo-radiological features of the lesions. From their own experience an d after a literature review, the authors conclude that: For lesions lo cated on the trunks of the renal artery, results of surgery and transl uminal angioplasty are equivalent. For lesions involving the ostium of the renal artery, the failure rate is high and restenosis are frequen t with angioplasty. In that case, surgery is a proper choice which off ers better immediate and long term results.
