Congenital high airway obstruction syndrome

Kanika Gupta, Bhuvaneswari Venkatesan, Kiruba Shankar Manoharan, Vaithianathan Rajalakshmi, Maya Menon
Congenital high airway obstruction syndrome is a rare fetal anomaly with characteristic constellation of prenatal findings on ultrasound and MRI. The typical triad of imaging features are enlarged and echogenic lungs, flattening or inversion of diaphragm and fetal hydrops. Early prenatal recognition of congenital high airway obstruction syndrome by ultrasound and/or MRI is mandatory for the appropriate perinatal management. We report a case of a male fetus with typical imaging findings of congenital high airway obstruction syndrome on ultrasound and MRI at 19 weeks of gestation...

Tracheal agenesis (TA) is a very rare congenital malformation of unknown aetiology. It is often associated with polymalformative syndromes; the neonates commonly present a critical condition during post-natal treatment. Pathology revolves around the triad of aphonia, respiratory distress syndrome and impossibility of endotracheal intubation. In contrast to the most important differential diagnosis, i. e., congenital high airway obstruction syndrome (CHAOS), surgical airway management is also impossible due to the absence of tracheal structures...

INTRODUCTION: Congenital high airway obstruction syndrome (CHAOS) is a rare, usually lethal abnormality characterized by complete or near-complete intrinsic obstruction of the fetal airway. Laryngeal atresia is the most frequent cause, but other etiologies include laryngeal or tracheal webs, laryngeal cyst, subglottic stenosis or atresia, tracheal atresia and laryngeal or tracheal agenesis. When antenatal diagnosis of possible upper airway obstruction is made, specific type of obstruction is rarely determined making the term CHAOS introduced by Hedrick et al in 1994 more appropriate...

Congenital high airway obstruction syndrome (CHAOS) is a very rare entity with very poor prognosis in which upper airway is intrinsically obstructed, the most common reason being laryngeal atresia. In summary prenatal early diagnosis of patients with CHAOS is necessary so that perinatal management can be undertaken successfully or elective termination of pregnancy can be undertaken. The fetoscopic approach may be a life saving modality in a subset of CHAOS patients. Involving a multidisciplinary team comprising of paediatricians, radiologists, obstetricians and anaesthesiologists increases the efficiency of management...

UNLABELLED: Tracheal damage, abnormality or absence can result from the growth of tumors or from Congenital High Airway Obstruction Syndrome. No optimal or routine treatment has been established for tracheal repair, despite numerous attempts with natural and artificial prostheses. The fetal trachea is comprised of cartilaginous rings connected by an elastomeric tissue. In an effort to design an engineered trachea replacement, we have synthesized 2-hydroxyethyl methacrylate hydrogels with moduli of 67 ± 3...

BACKGROUND: Children with medical complexity have a high prevalence of sleep disorders. However, outpatient polysomnography to evaluate for these conditions may be difficult to perform because of lack of skilled nursing care. The aim of this study was to explore polysomnography indications in hospitalized children and assess its impact on patient care. METHODS: Data from 85 inpatient polysomnographies of 70 children hospitalized between March and December 2014 were retrospectively collected...

The hybrid approach to management of hypoplastic left heart syndrome (HLHS) was developed as an alternative to neonatal Norwood surgery, providing a less invasive initial palliation for HLHS. We describe our experience in extending the concept of the hybrid procedure to palliate neonates with anatomically compromised systemic arterial blood flow in a variety of congenital cardiac anomalies and supporting its application as first-line palliation in centers developing their HLHS programs. Retrospective review of patients undergoing therapy for HLHS at a single institution from June 2008 to December 2014 was performed...

BACKGROUND: Congenital airway obstruction is rare but potentially fatal. We developed a complex airways interventional delivery team to manage such cases. Antenatal imaging detects airway compromise at an early stage and facilitates the planning of delivery procedures ('ex utero intrapartum treatment' and 'operation on placental support') which maintain feto-placental circulation whilst an airway is secured. METHOD: A retrospective review was performed of cases in which ENT input was required at birth for airway obstruction...

Tracheal agenesis is a rare congenital anomaly. The prevalence is less than 1 : 50 000 with a male to female ratio of 2 : 1. This anomaly may be isolated but, in 93% of cases, it is part of polymalformative syndrome. The most evocative diagnosis situation is the ultrasonographic congenital high airway obstruction syndrome. Dilated airways, enlarged lungs with flattened diaphragm, fetal ascites and severe nonimmune hydrops can be observed. In the absence of a congenital high airway obstruction syndrome, the antenatal diagnosis of tracheal agenesis is difficult...

Congenital high airway obstruction syndrome (CHAOS) is an extremely rare life-threatening condition. Laryngeal atresia appears to be the most frequent cause. Generally the diagnosis is made with severely enlarged and highly echogenic lungs and additional ultrasound findings. The prognosis of the affected infants is often poor. Five cases are reported here that were diagnosed in a tertiary center between 2008 and 2014.

In this case, we describe a newborn with prenatal diagnosis of congenital high airway obstruction syndrome (CHAOS), successfully managed with a cesarean section with delayed cord clamping 180 seconds. In case of prenatal diagnosis of CHAOS, prompt airway intervention at delivery allows survival of this otherwise fatal condition. Ex utero intrapartum treatment (EXIT) is considered the elective procedure to secure the fetal airway before the baby is completely separated from the maternal circulation. In cases where the EXIT procedure is not possible for maternal reasons (Ballantyne's syndrome), delayed cord clamping may serve as an alternative method to manage CHAOS...

BACKGROUND: Congenital high airway obstruction syndrome (CHAOS) is a rare life-threatening condition characterised by complete or near-complete developmental obstruction of the foetal airway. Although antenatal imaging findings have been described, the postmortem MRI findings have not been reported. OBJECTIVE: To present postmortem MRI features of CHAOS. MATERIALS AND METHODS: We retrospectively reviewed our hospital pathology and imaging databases for cases of CHAOS over a 2-year period...

At present, the fetus is already considered a "patient" and as such, can develop diseases with fatal outcome in which the only therapeutic option can be fetal surgery. Currently, fetal surgery is limited almost exclusively to endoscopic surgery. Different techniques have gained clinical acceptance for improving the prognosis of various lethal fetal pathologies. Laser therapy for twin to twin transfusion syndrome and cord occlusion in monochorionic twins with selective intrauterine growth restriction are the procedures of choice for the management of monochorionic twins complications, and are associated with survival rates of up to 80-90% for at least one fetus...
