Central Airway Obstruction with Persistent Pulmonary Decline After Vertebral Body Tethering

Abstract

Case: An 11-year-old girl with pectus excavatum presented with an acute airway obstruction and persistent pulmonary compromise after vertebral body tethering (VBT). The anterior instrumentation was occluding her right basilar bronchus, resulting in hyperinflation. Removal of the instrumentation reversed the hyperinflation. Conclusion: This case illustrates the difficulty of performing VBT in a small patient with severe scoliosis and significant asymmetric pectus excavatum. We recommend using low-profile instrumentation and ensuring the trajectory of the instrumentation is anterior to the rib head and parallel to the articular facets.
