Inadequate Diagnostic Utility of Partially Successful Adrenal Vein Sampling for Primary Aldosteronism Subtyping.

Endokrynol Pol 2021 May 19. Epub 2021 May 19.

Department of Endocrinology, Diabetes and Metabolic Diseases, University Medical Centre Ljubljana, Zaloska 7, 1525 Ljubljana, Slovenia.

Introduction: Failure of adrenal vein sampling (AVS) due to difficult cannulation of the right adrenal vein (AV) frequently precludes subtyping of patients with primary aldosteronism (PA) before adrenalectomy. According to a recent study, lateralized PA could be accurately predicted from partial AVS data based on the gradient of the aldosterone-to-cortisol ratios (ACR) between left AV and inferior vena cava (IVC) (LAV/IVC index). We aimed to validate the diagnostic utility of this index for PA subtyping in our cohort. Read More
