Conditions

primary aldosteronism caused by unilateral aldosterone hyper secretion

Interventions

CT guided radiofrequency ablation is performed with total power of 4-6kJ for aldosterone producing adrenal adenoma which is proven as unilateral functioning adenoma by adrenal venous sampling.

Eligibility

Sex/Gender

All
