Abstract

Obstructed infradiaphragmatic total anomalous pulmonary venous return (TAPVR) in premature infants presents significant management challenges due to the high surgical risk in low-birth-weight, preterm neonates. We present strategies for managing this condition in a 10-day old 1.3 kg ex-32-week premature infant including late umbilical venous access, use of wire-snare rail for stable stent deployment, and monitoring for progressive multi-level obstruction. Long-term follow-up demonstrated spontaneous stent fracture and occlusion. This approach successfully bridged to definitive repair with excellent outcomes.
