Clinical observation of intraluminal stent angioplasty in the treatment of renal arterial stenoses / 介入放射学杂志

ABSTRACT

Objective To evaluate the clinical application of intraluminal stent angioplasty(PTRAS) in the treatment of renal arterial stenoses. Methods A retrospective study was done in 28 patients with renal arterial stenoses. Primary renal artery stenting was performed in 28 consecutive patients (36 renal arteries). Blood pressure, serum creatine, the number of anti hypertensive medications were recorded at 1,6,12 month post stent angioplasty respectively. Arterial angiography was also taken 1 year later to evaluate the incidence of restenosis. Results Technical success rate was 100% achiving in all patients without serious complications. Primary successful patenty rate reached 82% (renal artery 86%), secondary successful rate was 89% (renal artery 90%). Systolic and diastolic blood pressure were reduced significantly ( P
