Thrombosis of the inferior vena cava in a patient with spinal cord injury.

Thrombosis of the inferior vena cava developed in a 25-year-old man with quadriplegia. The condition occurred six years after his cervical spinal cord injury. The patient had no previous history of thromboembolic disease. Clinical features of inferior vena cava thrombosis were massive bilateral lower extremity edema and dilated superficial abdominal veins. Based on the literature and outcome in this patient, anticoagulants provide the most effective long-term treatment.
