Abstract
|
|
|
|
Congenital high airway obstruction syndrome (CHAOS) is caused when the upper airway is obstructed or severely narrowed. The prenatal ultrasound findings of CHAOS include large echogenic lungs, inverted diaphragms, dilated airways, and fetal ascites and/or hydrops. Recently, exutero intrapartum treatment (EXIT) procedure or fetoscopic tracheostomy are being widely used for the treatment of CHAOS. However, CHAOS with early presentation of hydrops confers ominous sign even with EXIT procedure. We report a case of CHAOS with hydrops and associated anomalies that was confirmed by autopsy.
