Abdominal Pressing Maneuver During Adrenal Venous Sampling for Stabilization of Catheter Position

Purpose The abdominal pressing maneuver (APM) is to control respiration movement of the right adrenal vein (RAV) during adrenal venous sampling (AVS). Instability of a catheter inserted into the RAV due to respiration movement can be a factor contributing to the unfeasibility of AVS.
