A 4-hour-old infant with profound cyanosis on an alprostadil infusion was urgently transferred to Rady Children’s Hospital with suspected CHD. Upon arrival, urgent echocardiography was performed but could not confirm the presence of discrete pulmonary veins or pulmonary venous drainage. Given the difficulty in delineating the anatomy, a cardiac CT scan was performed and demonstrated a nearly atretic common pulmonary vein with multiple small collaterals that drained to systemic veins. Due to the high risk of mortality associated with operative repair, the decision was made to proceed with compassionate withdrawal of care. The described anatomy of common pulmonary vein atresia remains rare, and to our knowledge, fewer than 40 cases have been reported in the literature. Albeit rare, common pulmonary vein atresia should be considered in the differential diagnosis of a severely cyanotic neonate.

一名 4 小时大的婴儿在输注前列地尔后出现严重紫绀，被紧急转移到雷迪儿童医院，疑似患有冠心病。抵达后，进行了紧急超声心动图检查，但无法确认是否存在离散的肺静脉或肺静脉引流。鉴于难以描绘解剖结构，进行了心脏 CT 扫描，结果显示肺总静脉几乎闭锁，有多个小侧支引流至全身静脉。由于与手术修复相关的高死亡率风险，决定继续进行富有同情心的撤除护理。所描述的肺静脉闭锁的解剖结构仍然很少见，据我们所知，文献中报道的病例不到 40 例。虽然很少见，
