Percutaneous balloon aortoplasty for restenosis after extended aortic arch anastomosis for type B interrupted aortic arch.
A 4-month-old boy underwent a percutaneous balloon aortoplasty for restenosis after extended aortic arch anastomosis for type B interrupted aortic arch (IAA). Balloon aortoplasty resulted in a decrease in the peak systolic pressure gradient across the obstructive segment from 84 mmHg to 19 mmHg and in an increase in diameter from 2.5 mm to 4.3 mm. No complications related to the procedure were observed. We assume that balloon aortoplasty can be effective and safe for relieving postoperative aortic obstruction associated with IAA.
