Thrombosis of the superior vena cava is attached to several causes including deficiency of the protein S. It occurs gradually by a superior vena cava syndrome. ⋯ The radiological and biological assessments confirmed thrombosis of the superior vena cava and a deficit of the protein S for which the patient was put under anticoagulant therapy with good clinical and radiological improvement.
