Pseudoaneurysm following percutaneous balloon angioplasty for aortic arch recoarctation after the Norwood procedure.
We experienced a rare case of 5-month-old male infant presenting with a pseudoaneurysm following percutaneous balloon angioplasty for aortic arch recoarctation after undergoing the Norwood procedure. The pseudoaneurysm, which measured 1 cm in diameter, was located between the left carotid artery and the left subclavian artery. Under deep hypothermic circulatory arrest, resection of the pseudoaneurysm and reconstruction of the neoaortic arch were performed successfully.
