Surgical treatment of primary hyperaldosteronism.

Journal Article (Journal Article)

OBJECTIVE: A retrospective review of patients with primary hyperaldosteronism treated at the Duke University Medical Center was performed. SUMMARY BACKGROUND DATA: The management of patients with primary hyperaldosteronism has changed dramatically in the past 20 years. The outcome of surgical treatment was examined to optimize the management of these patients. METHODS: All patients who were evaluated for primary hyperaldosteronism before operation and who had adrenal surgery at Duke University Medical Center from 1970 to 1993 were included in the study. RESULTS: A ratio of plasma aldosterone concentration to plasma renin activity greater than 250 was predictive of hyperaldosteronism in 94% of patients. This ratio also predicted the size of the adenoma. Surgical treatment cured hypokalemia in 90% of the patients. Hypertension was cured or greatly improved, with an average decrease of 50.4 mmHg and 25.2 mmHg for systolic and diastolic pressures, respectively. Patients who had hypertension for less than 5 years achieved a satisfactory blood pressure response more often (13 of 14 patients) than did patients who had hypertension for 5 or more years (15 of 20 patients). CONCLUSIONS: Preoperative evaluation of patients with primary hyperaldosteronism using current modes allows a posterior approach to be used in most patients. Adrenalectomy cures hypokalemia and hypertension; however, patients with a history of hypertension for less than 5 years may be more likely to be cured by adrenal resection.
