Primary Aldosteronism Causing Aortic Dissection: A Case Report.

Area of Science:

• Endocrinology
• Cardiovascular Medicine
• Nephrology

Background:

• Primary aldosteronism (PA) is the leading cause of secondary hypertension, affecting up to 10% of patients in specialized centers.
• PA is frequently underdiagnosed due to nonspecific symptoms, yet it elevates risks for cardiovascular events and target organ damage.
• Young patients with severe or resistant hypertension warrant investigation for secondary causes, including PA, due to potential severe complications like aortic dissection.

Purpose of the Study:

• To highlight the critical association between primary aldosteronism and potentially fatal vascular abnormalities, specifically aortic dissection.
• To emphasize the importance of early diagnosis and intervention for PA in young individuals presenting with severe hypertension.

Main Methods:

• Case report of a 36-year-old male with severe hypertension, hypokalemia, and gingival hyperplasia.
• Diagnostic workup included imaging (aortic CT) revealing descending aortic dissection and biochemical tests confirming PA.
• Successful treatment involved laparoscopic right adrenalectomy for an adrenal cortical adenoma.

Main Results:

• The patient presented with poorly controlled hypertension and a descending aortic dissection.
• Biochemical findings confirmed primary aldosteronism (suppressed renin, elevated aldosterone, hypokalemia).
• Post-adrenalectomy, the patient experienced normalization of blood pressure and potassium levels, with symptom improvement.

Conclusions:

• This case underscores the necessity of screening for secondary hypertension, particularly PA, in young patients with severe or resistant hypertension.
• Undiagnosed PA can precipitate life-threatening conditions such as aortic dissection.
• Prompt diagnosis and surgical management of PA are vital for improving patient outcomes and preventing catastrophic vascular events.
