Case Report of Inferior Vena Cava Agenesis Accompanying Deep Vein Thrombosis

Abstract

A 17-year-old male patient was admitted to the author’s hospital complaining of pain in both flanks. He had a history of being admitted to a tertiary-level hospital a year before, for swelling of the left limb. Deep vein thrombosis (DVT) was observed in the left common iliac vein, and the patient received anticoagulation therapy for six months. Prior to revisiting the hospital, he was symptom free and claimed to be healthy. An abdominal CT scan showed findings of congenital absence throughout the entire length of the IVC. To prevent the obstruction of the multiple collateral vessels developed around the IVC, and to improve the renal venous drainage, the patient was immediately started on with anticoagulation therapy. Reported herein is a case of an incidentally discovered congenital anomaly of the IVC in a patient with DVT.
