In this study, we first conducted a 6-month follow-up in a swine model. Renal sympathetic nerve activity remained at a significantly lower level than that of the control group after 6 months. In patients with resistant hypertension, Cryo-RDN demonstrated preliminary safety. Renal function fluctuations and vascular-related complications were not detected. In addition, the average 24-hour systolic and diastolic blood pressure decreased by 12.17 ± 8.35 mm Hg and 8.50 ± 3.83 mm Hg at the 6-month follow-up, respectively, compared with their baseline values.
