Abstract

We report the technical and early clinical results of renal artery stent placement in 29 consecutive patients treated at a single centre over a 30-month period, employing the Palmaz balloon-expandable stent. Of 32 arteries treated, 23 (72%) were atheromatous, ostial stenoses. Immediate technical success was achieved in all 29 patients. Follow-up angiography was performed on 25 patients at 6.7 months (mean) and demonstrated a patient restenosis rate of 16%. All surviving patients were followed up for a minimum of 6 months. Blood pressure control was improved in eight (50%) of hypertensive patients, and renal function improved in seven (33%) and stabilized in six (29%) patients with chronic renal impairment (serum creatinine > 150 μmols/I). Complications occurred in seven (24%) of patients, including one procedure-related death. Our experience indicates that stent placement has an initial high technical success rate in renal artery stenosis and that this patency is maintained at repeat angiography with a low restenosis rate. Renal artery stenting is likely to extend the role of percutaneous renal revascularization especially in atheromatous ostial lesions. A randomized trial will be required to evaluate its role compared with balloon angioplasty. © 1997 The Royal College of Radiologists.
