[A case of tetralogy of Fallot associated with isolation of a subclavian artery and partial DiGeorge syndrome].
A month old girl was referred to our hospital for heart murmur and congestive heart failure. After the UCG and angiography, clinical diagnosis was tetralogy of Fallot, right aortic arch, isolation of left subclavian artery (Victorica type I), and a patent ductus arteriosus that originated from left subclavian artery. The direction of blood flow in the patent ductus arteriosus was from a subclavian artery to pulmonary artery, so she was in the condition of pulmonary over flow and appeared congestive heart failure, although she associated with tetralogy of Fallot. With intraoperative and postoperative examinations, we diagnosed the association of partial DiGeorge syndrome. Isolation of subclavian artery is uncommon, but this anomaly was classified by Victorica. Embryology of this anomaly was explained with hypothesis of double arch system. We had seen no reports of DiGeorge syndrome associated with isolation of a subclavian artery. But DiGeorge Syndrome is hypoplasia of branchiogenic organs, and subclavian arteries is differentiated from brachial arteries. So we supposed that this two lesions have the possibility of combination.
