• Abstract
  • To test the utility of endoprosthetic treatment for ostial renal artery stenosis, and to examine blood pressure and its treatment, serum creatinine and restenosis rate, forty-four ostial renal stent placements were performed in 30 patients with concomitant coronary artery disease, arterial hypertension and the indication for angiotensin converting enzyme (ACE) therapy. There was a marked decrease in systolic and diastolic blood pressure (163±30 to 145±17 and 93±18 to 83±10 mmHg; p<0.008) with a decrease in number of medication (3.2±0.9 to 2.8±1.0; p=0.005). In 5 out of 8 patients without ACE inhibitor, this drug could be added. Serum creatinine changed from 1.46±0.7 mg/dl to 1.39±0.58 mg/dl (p=ns). Three patients showed restenosis (12.5%). Ostial stenting lowers blood pressure, decreases antihypertensive drugs and increases medication flexibility.
