Adrenal Venous Sampling: Where Is the Aldosterone Disappearing to?
Cardiovascular and Interventional Radiology, 10/05/09

Solar M et al. – This finding is important for AVS because hepatic veins can easily be mistaken for adrenal veins as a result of their close anatomic proximity.

Aldosterone concentration in hepatic veins is uniformly lower than in mixed venous blood taken from the inferior vena cava, while no difference in cortisol concentrations was observed between the two veins. This finding may have implications for AVS because unintentional cannulation of hepatic veins instead of right adrenal veins can occur during adrenal catheterization. Caution should be taken when samples characterized by only mild increase in cortisol concentration (compared with inferior vena cava) are used for the interpretation of the results.
