The fetus with a potentially obstructed airway can be identified on routine antenatal imaging. These cases should be referred to fetal care centers, which have the necessary expertise to fully evaluate and manage these fetuses and neonates appropriately. Complete airway obstruction may result in fetal hydrops and intrauterine demise. If a newborn infant has a compromised airway at delivery, the inability to secure its airway quickly may result in a hypoxic cerebral insult or death. In the most severely affected cases, prenatal, perinatal, or postnatal surgical intervention may be necessary. The timing of such an intervention will depend on the exact cause of the airway obstruction, other associated findings and the anticipated difficulty in establishing an airway at delivery. Fetal ultrasound and magnetic resonance imaging can differentiate between intrinsic and extrinsic airway obstruction, which allows for the optimal planning and management of the delivery and neonatal resuscitation.
在常规产前影像学检查中可识别出气道可能受阻的胎儿。这些病例应转诊至胎儿护理中心,该中心具备充分评估和妥善处理这些胎儿及新生儿的必要专业知识。完全气道阻塞可能导致胎儿水肿和宫内死亡。如果新生儿在分娩时气道受损,无法迅速确保其气道通畅可能导致缺氧性脑损伤或死亡。在受影响最严重的病例中,可能需要进行产前、围产期或产后手术干预。这种干预的时机将取决于气道阻塞的确切原因、其他相关发现以及分娩时建立气道预计的难度。胎儿超声和磁共振成像可区分气道的内在和外在阻塞,这有助于对分娩和新生儿复苏进行最佳规划和管理。
