title: Anomalous origin of the left pulmonary artery from the aorta. Our experience and literature review.
abstract: Three patients with anomalous origin of the left pulmonary artery (AOLPA) from the aorta underwent surgical correction. Two patients presented with an isolated malformation and one with an associated ventricular septal defect. One of the patients with an isolated malformation presented with an AOLPA from the descending thoracic aorta. Implantation of the AOLPA to the main PA trunk was performed by direct anastomosis in two patients and by interposition of a synthetic graft in the other patient with AOLPA from the descending aorta. All patients survived the operation. Low cardiac output was identified in one patient. The mean residual gradient through the anastomotic site was 21 mmHg at follow-up. We found almost 72 cases with AOLPA reported in the literature with a high mortality rate in patients not undergoing surgery. The most frequently found associated malformation is tetralogy of Fallot and ventricular septal defect. AOLPA from the aorta is a rare but important entity, necessitating a scrupulous preoperative and intraoperative evaluation. Patients with AOLPA can undergo surgical repair with excellent results.
