Transarterial embolization of a hyperfunctioning aldosteronoma in a patient with bilateral adrenal nodules.

Primary hyperaldosteronism often results in resistant hypertension and hypokalemia, which may lead to cardiovascular and cerebrovascular complications. Although surgery is first line treatment for unilateral functioning aldosteronomas, minimally invasive therapies may be first line for certain patients such as those who cannot tolerate surgery. We present a case of transarterial embolization (TAE) of an aldosteronoma. The patient presented with a cerebrovascular accident, and subsequently developed uncontrolled hypertension, hypokalemia, and a myocardial infarction. Following TAE, potassium returned to normal levels and blood pressure control was improved. There were no postoperative complications. TAE thus may be a safe and effective alternative to surgery.
