The anomalous origin of the branch pulmonary artery from the ascending aorta (original) (raw)

2012, Interactive cardiovascular and thoracic surgery

The anomalous origin of one pulmonary artery branch from the aorta (AOPA) is rare. We report our single-institution surgical experience with this condition. Between January 1994 and February 2011, 17 patients (age: 1 month-25 years) with AOPA underwent surgery at our institute. Thirteen patients had an anomalous origin of the right pulmonary artery (RPA) while four had an anomalous origin of the left pulmonary artery (LPA) from the aorta. In patients with anomalous RPA, 11 patients had the proximal type and two patients had the distal type of AOPA. Four patients had associated Tetralogy of Fallot (TOF). In 14 patients, direct implantation into the main pulmonary artery was performed, while three patients required interpositon of a graft. There was one operative death due to persistent hypoxia in a 7-month old child with TOF and an anomalous LPA from the aorta. At a median follow-up of 36.5 months (range: 2-192 months), all 16 survivors were asymptomatic. On echocardiography, two pat...
