Abstract
Adrenal vein sampling (AVS) is a technically difficult procedure with published failure rates as high as 40%; most failures are due to problems identifying the right adrenal vein (RAV). We evaluated the use of the inferior accessory hepatic vein (IAHV) as an anatomical marker for the right adrenal vein. We also evaluated the use of a renal double curve catheter to cannulate the right adrenal vein.
