Kommerell Diverticulum in a Right-Sided Aortic Arch

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Vascular Surgery

Background:

• Kommerell diverticulum is a rare congenital aortic anomaly.
• It is characterized by an aneurysm at the origin of an aberrant subclavian artery, typically arising from a right-sided aortic arch.

Observation:

• A 57-year-old male presented with an aberrant origin of the left subclavian artery.
• This anomaly arose from a right-sided aortic arch originating from a large aneurysm in the proximal descending aorta.

Findings:

• The surgical strategy involved resection of the Kommerell diverticulum.
• Repair of the proximal descending aorta was achieved using deep hypothermic circulatory arrest.
• A left posterolateral thoracotomy approach was utilized.

Implications:

• This case highlights a successful surgical approach for managing complex Kommerell diverticulum.
• The described technique offers a viable option for aortic anomaly repair.
• Effective management of this rare condition is crucial for preventing complications.
