Abstract

Adrenal vein sampling (AVS) is considered the gold standard for differentiating unilateral from bilateral primary aldosteronism (PA). However, technical and anatomic factors may complicate interpretation. One such factor is the recognition of adrenal venous tributaries, as individual branches may carry markedly different aldosterone concentrations. We report the case of an unintended super-selective sampling on repeat AVS that resulted in a nondiagnostic selectivity index (SI) and thus an inconclusive study.
