title: Cerebral sinus thrombosis in a patient with hereditary protein S deficiency: case report and review of the literature.
abstract: Hereditary protein S deficiency is an established risk factor for venous thrombosis. The common sites of thrombosis are the deep leg and pelvic veins. We report on a 38-year-old female patient with hereditary protein S deficiency and a previous history of deep leg vein thrombosis, who developed thrombosis of the cerebral straight and superior sagittal sinus while taking oral contraceptives. The diagnosis was established by computerized tomography and carotid angiography. Lysis of the thrombus occurred during heparin treatment. The hereditary nature of protein S deficiency was documented by family studies, since nine additional family members deficient in protein S were identified. Nineteen published cases of cerebral vein thrombosis and a deficiency of either anti-thrombin III, protein C, or protein S were reviewed. Compared with patients without a deficiency state, the clinical features of cerebral vein thrombosis were similar except for an earlier onset and a positive medical history of venous thromboembolic events in a considerable number of patients.
