Application of Metanephrine and Normetanephrine in Evaluating the Selectivity of Adrenal Vein Sampling.

The aim of the study was to investigate the usefulness of metanephrine (MN) and normetanephrine (NMN) in bilateral simultaneous adrenal vein sampling (AVS) with and without ACTH stimulation. The study was conducted in a single referral center. Prospective recruited patients with PA were treated with AVS.

Effect of Adrenocorticotropic Hormone Stimulation During Simultaneous Bilateral Adrenal Vein Sampling in Primary Aldosteronism.

The aim of the study was to investigate the significance and influence of adrenocorticotropic hormone (ACTH) stimulation in primary aldosteronism (PA) patients with simultaneous bilateral adrenal vein sampling (AVS). All patients diagnosed with PA underwent simultaneous bilateral AVS with ACTH. In 95 patients, the post-ACTH SI significantly increased (p<0.
