Abstract：
Laryngeal atresia is a rare congenital anomaly that is usually diagnosed by antenatal ultrasound, however, if undiagnosed presents with desaturation after birth. A term neonate presented with airway obstruction after birth with multiple failed attempts at intubation and was rescued by proseal laryngeal mask airway (LMA). An esophagoscopy using an Ambuscope utilizing a modified connector assembly revealed an opening on the anterior wall of the esophagus with no esophageal atresia, leading to a diagnosis of H-type tracheo-esophageal fistula (TEF) with laryngeal atresia. The ability to ventilate the neonate via LMA with an absent glottic opening raised the possibility of TEF.
摘要：
喉闭锁是一种罕见的先天性异常，通常通过产前超声诊断，然而,如果未诊断出出生后出现去饱和。新生儿出生后出现气道阻塞，多次尝试插管失败，并通过前喉罩气道（LMA）抢救。使用改良的连接器组件使用Ambuscope的食管镜检查显示食管前壁有一个开口，没有食管闭锁。导致诊断H型气管食管瘘（TEF）伴喉闭锁。通过LMA在没有声门开口的情况下对新生儿进行通气的能力增加了TEF的可能性。
