[Surgical repair of isolated anomalous origin of left pulmonary artery from the ascending aorta in a 2-month-old infant].
A 2-month-old infant was referred to our department for evaluation of a congestive heart failure. The chest X-ray showed an enlarged globular heart. Further work-up was consistent with an anomalous origin of left pulmonary artery (PA) from the ascending aorta. The patient underwent a corrective surgery using cardiopulmonary bypass. The left PA was arising 15 cm above the aortic annulus and coursed in the curved manner to the left, crossing the main PA where the media of both vessels were fused. The ligamentum arteriosus, running from the top of the main PA to the right aortic arch, was divided. The left PA was detached at its origin and anastomosed to the main PA. The anterior wall of the main PA, where the media was fused, was reinforced with polytetrafluoroethylene (PTFE) patch. An angiogram 6 months after operation showed a rapid antegrade flow to the left PA, and angiographically normal luminal contour.
