Pulmonary artery sling is a rare congenital vascular anomaly. Partial anomalous left pulmonary artery is even rarer and no in utero observation has yet been reported. Here, we present the ultrasonographic findings of a 38-year-old woman at 32 weeks of gestation whose fetus showed a normal bifurcation of the pulmonary trunk into the right and left pulmonary arteries, but an anomalous origin of the left lower lobe pulmonary artery from the right pulmonary artery. These findings were confirmed by postnatal echocardiography and thoracic computed tomography.
肺动脉吊带是一种罕见的先天性血管畸形。部分性左肺动脉异常更为罕见，且尚未有宫内观察的报道。在此，我们报告了一例 38 岁孕妇 32 周时的超声表现，其胎儿的肺动脉干正常分为右肺动脉和左肺动脉，但左肺下叶肺动脉异常起自右肺动脉。这些发现通过产后超声心动图和胸部计算机断层扫描得到了证实。
