Article Synopsis
- Current guidelines recommend adrenal venous sampling (AVS) for determining the subtype of primary aldosteronism (PA), but success rates can be low at smaller medical centers, especially for bilateral cannulation.
- In a study involving 50 patients from 2009 to 2023, 66% underwent successful unilateral adrenalectomy, with specific indices developed to assess unilateral PA (uPA) effectively through unilateral-cannulating AVS.
- The study found that using a lateralization index and modified thresholds for the contralateral suppression index (CSI) and relative aldosterone secretion index (RASI) could accurately identify patients for unilateral adrenalectomy, achieving a higher positive predictive value than traditional imaging methods.
