Type D double aortic arch. Double aortic arch with interruption of its left component proximal to the site of origin of left common carotid artery.
Type D double aortic arch in a five year old boy (with interruption of left arch proximal to left common carotid artery)--with persistent ductus arteriosus and stenosis of right and left pulmonary arteries diagnosed during life is reported. At surgery for P.D.A., the anatomy was confirmed. There was no vascular ring. Types A, B and C double aortic arches with interruption of left arch respectively distal to P.D.A., proximal to P.D.A. and proximal to left subclavian artery have already been reported. Ours happens to be the first case of type D double aortic arch diagnosed ante-mortem and confirmed at surgery.
