Long-term outcomes after fetal therapy for congenital high airway obstructive syndrome.


Conference Paper

BACKGROUND/PURPOSE: Congenital high airway obstructive syndrome (CHAOS) is a rare and devastating condition that is uniformly fatal without fetal intervention. We sought to describe fetal treatment and long-term outcomes of CHAOS at a single referral center. METHODS: The medical records of patients with fetal CHAOS evaluated at our center between 1993 and 2011 were reviewed. Maternal history, radiographic findings, antenatal management, and postnatal outcomes were compared. RESULTS: Twelve fetuses with CHAOS were identified. Eleven had concomitant hydrops at diagnosis. Six were electively terminated, and 2 had intra- or peripartum demise. Four patients underwent fetal intervention. Two underwent delivery via ex utero intrapartum treatment (EXIT) procedure with tracheostomy placement only, and 2 underwent fetal bronchoscopy with attempted wire tracheoplasty followed by EXIT with tracheostomy at delivery. All 4 patients who underwent EXIT were alive at last follow-up. One patient was ventilator and tracheostomy free and feeding by mouth. CONCLUSION: Long-term and tracheostomy-free survival is possible with appropriate fetal intervention even in the presence of hydrops. Fetal intervention earlier in pregnancy may improve long-term outcomes, but patient selection for intervention remains challenging. Magnetic resonance imaging may help select those patients for whom fetal intervention before EXIT delivery may be beneficial.
