Endovascular IVC Reconstruction in an 18 Year Old Patient with Subtotal IVC Atresia

Introduction: Inferior vena cava (IVC) atresia is an uncommon venous anomaly that is an under recognised cause of unprovoked acute deep venous thrombosis (DVT) in young adults. The purpose of this case report is to highlight endovascular IVC reconstruction as a feasible treatment option, particularly in challenging cases when other therapeutic modalities have failed. Report: This is the report of an 18 year old patient with near complete IVC atresia and a longstanding history of exertional nausea of unknown aetiology, who presented with extensive acute DVT. He was treated successfully by endovascular IVC reconstruction after failing initial anticoagulation and thrombolysis. Symptom resolution and venous patency were maintained at 2.5 year follow up. Discussion: IVC atresia is an important aetiology to consider in a young patient presenting with unprovoked DVT. Endovascular stenting can restore venous patency and is feasible even when there is near complete IVC atresia. This case was uniquely challenging in the length of atretic IVC that was reconstructed and also highlights an atypical clinical presentation of IVC atresia.
