Abstract
Objective To investigate the clinical efficacy of percutaneous radiofrequency catheter ablation of renal sympa-thetic surgery for the treatment of refractory hypertension.Methods 73 Inpatients with refractory hypertension of our hospital from October 2011 to September 2012 were chosen ,and randomly divided into RDN group and control group. Clinical efficacy blood pressure control before and after surgery and laboratory parameters of the two groups were compared.Results The total efficiency of RDN group was 91.89% ,and that of the control group was 69.44% . Follow-up found that in RDN group 1 week ,1 month ,3 months ,6 months after treatment systolic and diastolic blood pressure decreased ,the difference was statisti-cally significant (both P<0.05). In the control group after treatment ,blood pressure decreased slowly ,compared with RDN group. Compared with the preoperative ,each postoperative laboratory index of refractory hypertension RDN was significantly different (all P<0.05). Each indicator of the control group after treatment was significantly different from that before treat-ment (all P<0.05) ,compared with the surgical group ,the difference was statistically significant (all P<0.05).Conclusion RDN is effective for patients with refractory hypotension to control blood pressure.关键词
