Abstract
From September 2009 to September 2013 seven patients diagnosed with unilateral adrenal APA and underwent computed tomography CTguided percutaneous RFA were recruited in this retrospective study Eighteen unilateral adrenal APA with the same tumor size 25 mm who underwent LA during the same interval were enrolled as control group Treatment success was defined as complete tumor ablation on followup CT scan and normalization of serum aldosteronetorenin ratio We also compared “normalization ability” between RFA group and LA group Normalization ability was defined as reduction in blood pressure decrease in number of antihypertensive medicine use reduction in serum aldosterone and increase in serum potassium levelThere was no statistically significant demographic difference in both groups The mean tumor size was 18 8–25 mm in RFA and 19 11–25 mm in LA groups respectively There was only one intraprocedure hypertensive crisis in the RFA group No other complications needed further management in both groups During an interval of 3–6 months of followup the treatment success rate reached 100 in the RFA group versus 944 in the LA group Normalization ability was statistically equivalent in the RFA and the LA group Comparing with LA group RFA group demonstrated with less postoperative pain visual analog scale 20 ± 116 vs 422 ± 144 p 0001 and shorter operative time 105 ± 34 vs 194 ± 58 min p 0001
