Feasibility of Imaging-Guided Adrenalectomy in Young Patients With Primary Aldosteronism.

Hypertension 2022 01 17;79(1):187-195. Epub 2021 Nov 17.

3rd Department of Medicine, Charles University Prague, General Hospital, Czech Republic (J.W., Z.K.).

Many of the patients with primary aldosteronism (PA) are denied curative adrenalectomy because of limited availability or failure of adrenal vein sampling. It has been suggested that adrenal vein sampling can be omitted in young patients with a unilateral adrenal nodule, who show a florid biochemical PA phenotype. As this suggestion was based on a very low quality of evidence, we tested the applicability and accuracy of imaging, performed by computed tomography and/or magnetic resonance, for identification of unilateral PA, as determined by biochemical and/or clinical cure after unilateral adrenalectomy.
