Percutaneous Orthotopic IVC Construction in a Pediatric Patient with Symptomatic IVC Agenesis.

Inferior vena cava agenesis is an uncommon condition usually attributed to embryologic dysgenesis. When symptomatic, unprovoked deep venous thrombosis and/or lower extremity venous congestion are the most frequent manifestations. Its rarity has precluded consensus regarding appropriate management. Symptomatic chronic venous congestion requires surgical construction of auxiliary venous pathways, which may involve substantial morbidity, prolonged recovery and extensive scarring. We report successful minimally invasive management via percutaneous endovascular orthotopic inferior vena cava construction in a pediatric patient, thereby obviating the need for surgery and its associated morbidity. LEVEL OF EVIDENCE: Level IV, case study.
