Nwariaku FE, Miller BS, Auchus R, et al. Primary Hyperaldosteronism: Effect of Adrenal Vein Sampling on Surgical Outcome. Arch Surg. 2006;141(5):497–503. doi:10.1001/archsurg.141.5.497
Adrenal vein sampling is superior to computed tomography for subtype differentiation of primary hyperaldosteronism.
University medical center.
Forty-eight patients (32 men and 16 women) with biochemically confirmed primary hyperaldosteronism.
Main Outcome Measures
We compared demographic factors, results of biochemical and imaging studies (computed tomography and adrenal vein sampling), therapy, and patient outcomes.
Mean ± SEM adrenal nodule size was 1.54 ± 0.2 cm. Adrenal vein sampling was performed in 41 (85%) of 48 patients, and it was successful in 39 (95%) of those 41 patients. Concordance between computed tomography and adrenal vein sampling was observed in 22 (54%) of the 41 patients. Thirty-two patients underwent successful laparoscopic adrenalectomy. There was 1 complication and no deaths. All 32 patients were cured of hypokalemia.
Adrenal vein sampling is superior to image-based techniques for subtype differentiation of primary hyperaldosteronism.
