[Tracheal aplasia--an especially rare and dramatic anomaly]

Area of Science:

• Pediatric Surgery
• Neonatology
• Congenital Anomalies

Background:

• Tracheal agenesis (TA), including aplasia or atresia, represents a severe congenital anomaly with a historically poor prognosis.
• Current treatment strategies for TA are limited, with no established long-term solutions.
• The diagnosis of TA is often challenging, frequently occurring postnatally, which significantly impacts the infant's outcome.

Observation:

• Prenatal suspicion of duodenal stenosis, unexplained neonatal aphonia, or failed intubation attempts can suggest TA.
• A case report details the demise of a premature infant due to postnatal diagnosis of tracheal aplasia after intensive care withdrawal.
• Timely postnatal diagnosis is critical for determining the prognosis and guiding management decisions.

Findings:

• Tracheal agenesis remains incompatible with life without timely and effective intervention.
• Sufficient proximal or distal tracheal length is a prerequisite for tracheostomy, offering a potential pathway for survival.
• Advanced medical interventions, including ex utero intrapartum procedure (Exit), extracorporeal membrane oxygenation (ECMO), and reconstructive surgery, present new therapeutic avenues.

Implications:

• Improved prenatal diagnostic capabilities for TA are crucial for early intervention planning.
• Multidisciplinary decision-making is essential for managing infants with TA, considering peripartal and historical factors.
• Further research into novel surgical techniques and supportive therapies is needed to improve survival rates for tracheal agenesis.
