The study aimed to assess the security and clinical efficacy of percutaneous transluminal renal artery stenting (PTRAS) among patients with atherosclerotic renal artery stenosis (ARAS).
The clinical data of 172 patients with ARAS treated by PTRAS, were collected from January 1998 to January 2015, including baseline data, postoperative 72 hours and long term follow-up.
Compared with preoperative, systolic blood pressure (SBP) and diastolic blood pressure (DBP) of postoperative 72 hours and long term follow-up was decreased significantly. Patients in different gender compared with the preoperative, the blood pressure of postoperative 72 hours and long term follow-up in male patients, and the blood pressure of postoperative 72 hours in female were decreased significant (P <0.05), but the blood pressure of long term follow-up in female were no decreased significantly (P = 0.847). The occurrence rate of contrast induced acute kidney injury after PTRAS was 9.9% (17/172), and multivariate analysis indicated that the diagnosis of acute myocardial infarction and diabetes mellitus were independent risk factors for postoperative contrast induced acute kidney injury During the follow-up period, there were 11 cases (9.1%) all-cause mortality.
PTRAS treatment of patients with ARAS. Renal function of postoperative 72 hours and long term follow-up was stable, and the incidence of contrast induced acute kidney injury is low.
