[Primary hyperaldosteronism and adrenal tumors. Clinico-surgical experience with 9 patients].
OBJECTIVE
To report seven patients with diagnosis of primary aldosteronism, five of them due to aldosterone-producing adenoma (APA) and two due to idiopathic hyperaldosteronism (IHA), and two patients with adrenal non-producing tumors in order to discuss our experience on differential diagnosis and treatment of this hypertensive disease.


METHODS
Hypokalemia and higher values of urinary potassium in the absence of diuretics were useful to the screening diagnosis of primary aldosteronism, reinforced by suppressed plasma renin activity either at rest and after deambulation and by higher values of plasma aldosterone. Computerized tomography in all patients and selenium-cholesterol scintigraphy were used to make the localization of tumors and differential diagnosis between APA and IHA.


RESULTS
The patients with adrenal tumors were submitted to surgical treatment and the two patients with IHA were submitted to spironolacone therapy. After 1 to 5 years of follow-up, we observed cure of hypertension and hypokalemia in three patients after surgery and improvement of blood pressure control and normalization of serum potassium in the six others.


CONCLUSIONS
The diagnosis of primary aldosteronism is important, besides its rarity, because surgical or appropriated clinical treatment provide cure of hypertension or improvement of blood pressure control in most of patients.
