PERCUTANEOUS TRANSLUMINAL RENAL ANGIOPLAS TY BEFORE SURGICAL AORTIC REVASCULARIZATION

Purpose: to evaluate the results of the association of a percutaneous transluminal renal angioplasty before a surgical revascularization of the infra-renal aorta. Patients and methods : percutaneous translumina l angioplasty of one (n = 12) or two (n = 2) renal arteries have been performed in 14 patients (If hypertensive and one with azotemia), 2 to 240 days (mean 54) before infra-renal aortic surgery (aneurysms: 8, o cclusive disease : 6). Results: 15 of the 16 dilatations were complete ly technically successful (residual stenosis less than 20%), with one groin hematoma treated medically. Mean duration of the surgical interv ention were 137 minutes (occlusive disease) and 147 minutes (aneurysm) . In the post-operative course were noted resolutive infections in two patients, and one death because of myocardial infarction. At the end of the follow-up (3 to 60 months, mean 32), all of the 13 patients ali ve had improved in terms of vascular disease. Hypertension was improve d for 2 patients, stable for 10, worse for 1. Creatinine serum level w as stable for 12 patients, and the renal insufficient was worsened. Co nclusion: combined percutaneous transluminal renal angioplasty and aor tic revascularization seems to be reliable and safe; it can be an alte rnative to a simultaneous aortic and renal revascularization, notably for high-risk patients.
