ABSTRACT

BACKGROUND: In the last decade the therapeutic concept of renovascular disease has changed. The numbers of primary surgical revascularisations have fallen substantially due to the invention of percutaneous transluminal angioplasty (PTA). PATIENTS AND METHODS: Retrospective data analysis. From September 1992 to December 2001, 42 patients were operated on 49 renal arteries at our institution. During the same period, 166 PTA of renal arteries alone and 92 PTA with stent were performed. Twenty-five patients and 27 renal arteries were operated encompassing an aortic reconstruction due to atherosclerosis (aortic occlusion 14, aortic aneurysm 11). The median age at operation was 61 years (range 47 years to 76 years). Four patients were operated on because of renal artery aneurysms with a diameter of more than 2.5 cm. The median age of these patients was 68.5 years (range 60 years to 77 years). Seven patients presented with atherosclerotic changes of the renal artery without aorto-iliac involvement. Their median age was 62.8 years at operation (range 39 years to 77 years). Of these, one suffered from rupture of the renal artery during PTA and needed emergency surgery: Six patients and 11 renal arteries with FMD were surgically reconstructed. RESULTS: The primary patency rate of all reconstructed renal arteries of surviving patients after 5 years was 92%, the secondary patency rate after 5 years was 98%. Two patients died perioperatively (4.7%). One patient had presented with a symptomatic thoraco-abdominal aneurysm and died ultimately because of a stroke. The second patient had an infrarenal AAA and died after a myocardial infarction. Twenty (47.7%) of all surgically treated patients had had at least one PTA preoperatively. CONCLUSION: During the last decade, primary surgical renal artery reconstruction was performed in about half of the cases. The decrease of primary open surgery of the renal arteries was most striking in patients with aorto-iliac occlusive disease. From 1996 on no patient of this group underwent open surgery without having had prior PTA of the renal arteries.
