Absent left pulmonary artery and double aortic arch in tetralogy of Fallot: reconstruction using homograft saphenous vein or iliac artery.

Two cases of tetralogy of Fallot (TOF) with double aortic arch and absent left pulmonary artery are reported. Single-stage repair was performed using a left thoracotomy for division of the non-dominant arch followed by complete repair through a median sternotomy. In both patients, the left pulmonary artery was reconstructed using either a homograft saphenous vein or a homograft common iliac artery.
