Abstract:
Objective To explore the short term efficacy and safety of percutaneous transluminal renal artery stenting in patient with renal artery stenosis.Methods From January 2003 through June 2012,fifty hypertension patients with unilateral or bilateral renal artery stenosis ≥70％ were successfully treated by percutaneous translumminal renal angioplasty with stent (PTRAS).There were 32 males and 18 females with an average age of (51.2 ± 12.3) years ranged from 21 ～78 years.The blood pressure level,dosage of anti-hypertension drugs and serum creatinine (Scr) of patients were documented and analyzed before and after stenting.All patients were clinically followed up for 6 months after stenting.Continuous variables were analyzed by using t-test for comparison among patients.Results The technical success rate was 100％.Of them,16 patients were cured,30 patients improved and 4 patients ineffective.There were significant differences in blood pressure,sCr and dosage of anti-hypertension drugs between post-stenting and prestenting [SBP (145.7 ±11.3) vs.(179.1 ±22.3) mmHg; DBP [(75.1±9.2) vs.(112.5 ±19.2)mmHg],sCr [(138.2 ±20.3) vs.(191.1 ±36.5) μmol/L] (P＜0.01) and the dosage of antihypertension drug was dramatically decreased.And there were no adverse events found during follow-up period.Conclusions The success rate of PTRAS technique was high,and the blood pressure of patients could be effectively controlled by it,being beneficial to renal function.
