Prolonged Zona Glomerulosa Insufficiency Causing Hyperkalemia in Primary Aldosteronism after Adrenalectomy

Abstract

Persistent postoperative hypoaldosteronism with hyperkalemia occurs in 5% of adrenalectomized PA patients through prolonged ZG insufficiency, requiring long-term fludrocortisone treatment. Potassium levels after adrenalectomy must be monitored to avoid life-threatening hyperkalemia.
