Utility of a partial autopsy: a case report of congenital laryngeal atresia.

Laryngeal atresia is a rare congenital anomaly that is fatal if not quickly diagnosed at birth. Here we report a case of unexpected congenital laryngeal atresia and esophageal atresia in a preterm male infant, in whom prenatal ultrasonic findings were limited to polyhydramnios and duodenal atresia. Attempts at intubation and emergent tracheotomy were unsuccessful. A diagnosis of congenital laryngeal atresia with esophageal atresia was made during a restricted autopsy (limited to the neck). In an era of declining autopsy rates nationwide, this case emphasizes the value of limited autopsy examinations, focused on the region of interest.
