Summary
Adrenalectomy during pregnancy effectively managed primary hyperaldosteronism, resolving hypertension and hypokalemia. This intervention led to a successful pregnancy outcome, highlighting a safe treatment option for this rare condition.
Area of Science:
- Endocrinology
- Obstetrics
- Surgical Management
Background:
- Primary hyperaldosteronism is a rare condition with limited data on its management during pregnancy.
- Uncontrolled hypertension and hypokalemia in pregnancy pose significant risks to both mother and fetus.
Observation:
- A 31-year-old woman with suspected primary hyperaldosteronism presented with refractory hypertension and hypokalemia.
- Pregnancy occurred before definitive treatment; hypertension persisted despite medication.
- An adrenalectomy was performed at 15 weeks' gestation due to uncontrolled blood pressure.
Findings:
- Adrenalectomy led to rapid and sustained improvement in blood pressure and resolution of hypokalemia.
- Antihypertensive medications were discontinued, maintaining normal blood pressure throughout the pregnancy.
- A healthy infant was delivered at term via cesarean section.
Implications:
- Surgical management (adrenalectomy) can be a safe and effective treatment for primary hyperaldosteronism in pregnancy.
- Early intervention improves maternal and fetal outcomes, mitigating risks associated with uncontrolled hypertension.
- This case adds to the limited evidence supporting surgical options for this condition during gestation.
