Adrenal venography and sampling in the diagnosis and treatment of primary aldosteronism.

Adrenal venography and adrenal venous blood sampling for aldosterone and cortisol estimations have been attempted in eight patients with primary aldosteronism. The techniques accurately predicted the location of the aldosterone secreting tumour in all six patients in whom an adrenal vein cannulation was possible. The techniques are useful in the surgical management of solitary adrenal adenomas and are important in the choice of optimal therapy for the variety of disorders presenting as primary aldosteronism.
