Transcatheter adrenal arterial embolization of cortisol-producing tumors -Two cases of Cushing's syndrome

Transcatheter arterial embolization (TAE) was performed in 2 patients with Gushing's syndrome caused by adrenal adenoma by using a mixture of absolute ethanol and iohexol. In 1 patient successful suppression of the hypersecre tion of cortisol has continued for 9 months after TAE without complications . However, in the other patient, TAE was discontinued due to marked hyperte nsion and tachycardia induced by a massive release of catecholamines from t he embolized "normal" part of the tumor-bearing adrenal gland during the pr ocedure. These results suggest that it is important to perform TAE of only the arterial branches feeding the tumor.
