Airway stents in children

Area of Science:

• Pediatric Pulmonology
• Interventional Pulmonology
• Pediatric Surgery

Background:

• Airway obstruction in children presents unique challenges due to narrow, soft airways and the need for growth adaptation.
• While airway stenting is successful in adults, its application in pediatric patients requires careful consideration of distinct physiological differences.

Purpose of the Study:

• To evaluate the role and outcomes of airway stenting in pediatric patients with airway obstruction.
• To compare the efficacy and complications of different stent types (metal vs. silicone) in children.

Main Methods:

• Review of existing literature on pediatric airway stenting.
• Analysis of stent placement techniques, stent types, and associated outcomes.
• Assessment of complications, including granulation, secretion retention, and mortality.

Main Results:

• Metal stents generally provide better airway patency and clinical improvement compared to silicone stents in children.
• Complications like granulation and secretion retention are common, and severe adverse events, including a 12.9% mortality rate, have been reported.
• Stent placement requires expertise for proper sizing and type selection, and adaptation for growth is limited.

Conclusions:

• Airway stenting in children should be reserved for cases with no viable alternatives, following thorough consideration of all surgical and medical options.
• Palliative stenting may be a reasonable option. Metal stents are often permanent, posing challenges for removal due to potential surgical risks.
