  • Title: Adrenal venous catecholamine concentrations in patients with adrenal masses other than pheochromocytoma.
    Author: Baba Y, Nakajo M, Hayashi S.
    Journal: Endocrine; 2013 Feb; 43(1):219-24. PubMed ID: 22971951.
    Abstract:
    The aim of this study was to retrospectively examine adrenal venous catecholamine concentrations and related indices in non-pheochromocytoma patients and to estimate from the obtained results whether measurements of adrenal venous catecholamine concentrations by adrenal venous sampling (AVS) are useful for localizing adrenal pheochromocytoma. The study population comprised 15 patients in whom AVS was performed for evaluation of adrenal non-pheochromocytoma masses (primary aldosteronism, n = 8; Cushing syndrome, n = 5; non-hyperfunctioning tumor, n = 2) without hormonal intervention and was successful in bilaterally judging adrenal vein to infra-renal inferior vena cava cortisol ratios as >3.0. Wide ranges of catecholamine concentrations were seen for both right (epinephrine, 35-175,821 pg/ml; norepinephrine, 115-32,102 pg/ml; dopamine, 9-232 pg/ml) and left (epinephrine, 16-27,251 pg/ml; norepinephrine, 155-9,267 pg/ml; dopamine, 5-234 pg/ml) adrenal veins. High- to low-side adrenal vein concentration ratios also showed wide ranges of up to 779 for epinephrine, 22.5 for norepinephrine, and 7.8 for dopamine. Adrenal venous catecholamine concentrations obtained by AVS and simple comparisons between bilateral adrenal veins might not be useful to localize adrenal pheochromocytoma, as wide variations in concentrations and high- to low-side adrenal vein concentration ratios were noted in patients with adrenal non-pheochromocytoma.
