Aortic arch augmentation using a pulmonary artery autograft patch and a reversed left subclavian artery flap for an interrupted aortic arch type B complex.

: Adequate arch augmentation for interrupted aortic arch repair is quite important to avoid post-operative recoarctation and bronchial compression. We describe here two successful cases of aortic arch reconstruction using autologous materials such as a pulmonary artery patch and a reversed left subclavian artery flap in infants with an interrupted aortic arch type B complex.
