Abstract Objective: To investigate the prenatal ultrasonic manifestation and diagnosis of congenital high airway obstruction syndrome(CHAOS). Methods: Five cases of CHAOS were diagnosed by prenatal ultrasonography. The prenatal ultrasonic manifestations and key points for diagnosis of CHAOS were analysed and concluded. Results: Three cases were comfirmed by autopsy, one was comfirmed by local exploration after termination of pregnancy, and one was lost during follow up. The characteristic prenatal ultrasonic manifestations of CHAOS were hyper-echogenic and symmetrical enlarged lung fields, flattened or inverted diaphragm and dilated trachea, as well as small and compressed heart. Conclusions: The prenatal ultrasonic manifestations of CHAOS were characteristic. CHAOS can be prenatally diagnosed.
