Autologous Tissue Reconstruction of Interrupted Aortic Arch Using Aberrant Subclavian Artery.

Reconstruction of the aortic arch in type B interruption requires extensive mobilization of the descending aorta and the proximal branches of the arch to perform a tension-free anastomosis. The association of a coexistent type II aortopulmonary window and an aberrant subclavian artery reduces the degree of mobility that can be achieved by dissection alone, and it usually entails sacrifice of the aberrant artery to achieve satisfactory mobilization. We report a novel technique to use the aberrant subclavian artery as autologous tissue in the reconstruction of the aortic arch for repair of type B interruption associated with type II aortopulmonary window.
