[Extended aortic arch replacement through gull-wing approach to Kommerell's diverticulum and aneurysmal right-sided aortic arch with aberrant left subclavian artery]

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Vascular Surgery

Background:

• Kommerell's diverticulum is a rare congenital anomaly.
• Aneurysmal dilatation of the right-sided aortic arch is uncommon.
• Aberrant left subclavian artery can be associated with aortic arch pathologies.

Observation:

• A 76-year-old male patient presented with symptomatic Kommerell's diverticulum and an aneurysmal right-sided aortic arch with aberrant left subclavian artery.
• The patient required surgical intervention due to the complexity of his condition.

Findings:

• Extended aortic arch replacement was successfully performed using the gull-wing approach.
• The patient experienced an uneventful recovery with no postoperative complications.

Implications:

• The gull-wing approach offers a significantly wide surgical field.
• This technique may be advantageous for managing extensive and complex thoracic aortic diseases.
• Successful application in this case suggests potential for broader use in similar pathologies.
