Objective To summary the effects and prospects of percutaneous radiofrequency catheter-based renal sympathetic denervation for resistant hypertension. Methods Literatures which about the relationship between renal sympathetic nerves and hypertension， and the technical prospect and inadequacy of percutaneous radiofrequency catheter-based renal sympathetic denervation for resistant hypertension， were analyzed and reviewed. Results Hypertension， which as a seriously public health problem， was the focus of clinical treatment currently. Renal sympathetic nerve was certified playing an important role in regulation of blood pressure， and percutaneous radiofrequency catheter-based renal sympathetic denervation had potential superiority in the treatment of resistant hypertension. Conclusion Percutaneous radiofrequency catheter-based renal sympathetic denervation is an effective method for resistant hypertension.
ObjectiveTo review the progress of percutaneous radiofrequency catheter-based renal sympathetic denervation for resistant hypertension as well as the inadequacy, and to reevaluate the clinical significance of the technology. MethodsDomestic and foreign literatures were collected to summary the progress of percutaneous radiofrequency catheter-based renal sympathetic denervation in treatment of resistant hypertension. ResultsThe percutaneous radiofrequency catheter-based renal sympathetic denervation in the treatment of resistant hypertension had obtained some positive results recently, but the long-term outcomes and safety of the technology were still subjected to further evaluation. ConclusionThe effect of percutaneous radiofrequency catheter-based renal sympathetic denervation for resistant hypertension remains to be controversial, and both the equipment and technology of radiofrequency catheter-based ablation need to be improved.
