  • Title: Selective blood sampling in adrenal hypertension.
    Author: Kahaly G, Krause U, Ritthaler H, Cordes U, Günther R, Schrezenmeir J, Beyer J.
    Journal: Cardiology; 1985; 72 Suppl 1():179-81. PubMed ID: 4053128.
    Abstract:
    Selective venous blood sampling was performed in 89 patients with hypertension (14 pheochromocytoma, 10 Conn's syndrome, 8 Cushing's disease, 57 essential hypertension). We looked for diagnostic criteria and the valuability of blood sampling from the adrenal veins in such diseases. Defining a norepinephrine concentration of more than 8,000 ng/l as pathological, we had an accuracy of 94.6%. Defining an aldosterone concentration of more than 1,400 pg/ml as pathological, we had an accuracy of 97.4%. In Cushing's disease this method was not very helpful due to overlapping results.
