[Reimplantation of an aberrant right subclavian artery into the ascending aorta in dysphagia lusoria in childhood]

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Thoracic Surgery

Background:

• Arteria lusoria, a rare congenital anomaly, involves an aberrant right subclavian artery originating from the aortic arch.
• This condition can lead to dysphagia lusoria or other vascular complications.
• Understanding the anatomical variations is crucial for surgical planning.

Observation:

• Two infants diagnosed with arteria lusoria were evaluated.
• The primary clinical concern was establishing orthograde flow to the right subclavian artery.
• Surgical intervention was deemed necessary for anatomical reestablishment.

Findings:

• Successful surgical treatment was achieved in both infants.
• Reimplantation of the aberrant right subclavian artery into the ascending aorta was performed.
• The procedure was completed without the need for graft interposition, utilizing a right thoracotomy approach.

Implications:

• Direct reimplantation is a viable and effective surgical strategy for arteria lusoria in pediatric patients.
• This approach avoids the potential complications associated with vascular grafts.
• The findings support right thoracotomy as a suitable surgical access for this procedure.
