Anomaly of the aortic arch: a case report

Area of Science:

• Cardiovascular Surgery
• Congenital Heart Disease
• Vascular Anomalies

Background:

• Aortic arch anomalies are rare congenital conditions.
• Subclavian steal syndrome can result from specific aortic arch malformations.
• The double aortic arch with an obliterated left arch is an uncommon variant.

Observation:

• A patient presented with symptoms of subclavian steal syndrome.
• The underlying cause was identified as a hypoplastic left subclavian artery.
• This was associated with a double aortic arch and an obliterated left aortic arch.

Findings:

• Surgical intervention involved replacing the hypoplastic left subclavian artery with a Dacron tube graft.
• The obliterated left aortic arch was surgically divided.
• These procedures successfully resolved the subclavian steal syndrome.

Implications:

• This case highlights a successful surgical approach for a complex aortic arch anomaly.
• Effective management of subclavian steal syndrome in this context leads to good patient outcomes.
• Demonstrates the importance of accurate diagnosis and tailored surgical repair for rare vascular malformations.
