Multimodal imaging assessment for feasibility of endovascular reconstruction in cases of inferior vena cava atresia.

Key Clinical Message: Inferior vena cava atresia is a rare condition with highly variable anatomy due to the complexity of caval embryology. When endovascular venovenous reconstruction is considered for severe persistent sequelae, multimodality imaging with CT and invasive venography is used to determine the appropriateness of intervention and for procedural planning.
