Successful palliation by means of a bovine artery graft in a 4-day-old infant with type B interruption of aortic arch and right descending aorta.

In a 4-day-old baby a unique form of interrupted aortic arch was diagnosed, where the interruption was located between the right carotid and the right subclavian arteries in a right descending aorta. The additional large ductus was ligated, the VSD was palliated with pulmonary arterial banding. For the repair of the interrupted aortic arch with its long distance between the ascending and descending portions and the complicating proximity of the superior vena cava, a long pliable material had to be used. The anastomosis was successfully performed with a bovine arterial heterograft.
