The results of percutaneous angioplasty and stent implantation for critical ostial renal artery stenosis
open access
Abstract
Material and method: From the year 2000 through 2003 percutaneous angioplasty with stenting of renal artery stenosis was performed in 25 patients. The study group comprised 8 male and 17 female patients, aged 43 to 79 years (mean age: 59.6 years). Arterial hypertension was the indication for surgery in twentyfour patients, 5 of whom also suffered from chronic renal failure. One patient was selected due to acute renal failure. Patient selection was based on the presence of critical ostial stenosis (> 70%) of the renal artery. Seven patients (28%) presented with bilateral stenosis; two others had occlusion of the contralateral renal artery with renal cirrhosis.
Results: Technically, stent implantation was 100% success. A perioperative creatnine increase (> 1.5 mg%) was observed in 11 patients (44%). Two patients required kidney dialysis; one of whom developed multiorgan failure, and subsequently myocardial infarction, which was the immediate cause of death. Following the procedure, a decline in blood pressure or a decrease in the number and dose of antihypertensive drugs was observed in 19 subjects (76%); however, the effect proved shortlasting in most of them. Significant restenosis (> 50%) was found in 2 patients (8%). Two others (8%) developed perioperative haematomas at the arterial puncture site.
Conclusions: Percutaneous angioplasty, in patients with critical ostial stenosis of the renal arteries and resultant hypertension, is a safe method of treatment and yields a decline in blood pressure or a decrease in the number and dose of antihypertensive drugs in most patients.
