Use of Bony Landmarks during Adrenal Venous Sampling to Guide Catheterization of the Left Adrenal Vein
Purpose The aim of this study was to examine the utility of fluoroscopic bony landmarks in predicting the location of the left adrenal vein during adrenal vein sampling (AVS). Methods Eighty-six AVS procedures were performed in 81 patients between August 2013 and March 2020. A selectivity index was...
