[A case report of anomalous origin of right pulmonary artery from innominate artery associated with left sided unilateral pulmonary hypertension].

A 7-year-old girl, who was diagnosed as anomalous origin of right pulmonary artery from innominate artery associated with left sided unilateral pulmonary hypertension due to left patent ductus arteriosus, was reported. The right pulmonary artery had a stenotic segment of it's origin containing ductal tissue. Operation was performed without the aid of cardiopulmonary bypass. The continuity between main and right pulmonary arteries was established by a pericardial roll graft. The postoperative course was uneventful and she is very well three years after correction. To our knowledge, this is a very rare case with such combination of congenital anomalies as anomalous origin of right pulmonary artery and left sided unilateral pulmonary hypertension to be reported in the literature in Japan.
