Anomalous origin of a branch pulmonary artery from the aorta is a rare malformation, accounting for 0.12% of all congenital heart defects. Anomalous origin of the left pulmonary artery from the aorta (ALPA) constitutes a small proportion of these cases. ALPA has been reported to arise from the ascending aorta with various embryologic postulates. We report a case of isolated ALPA arising from the descending aorta in association with a patent ductus arteriosus, to emphasize its embryologic ambiguity.
一支肺动脉从主动脉异常起源是一种罕见的畸形，占所有先天性心脏缺陷的0.12%。左肺动脉从主动脉异常起源（ALPA）在这些病例中占一小部分。据报道，ALPA可起源于升主动脉，并存在各种胚胎学假说。我们报告一例孤立性ALPA起源于降主动脉并伴有动脉导管未闭的病例，以强调其胚胎学上的不明确性。
