Cerebral Sinus Venous Thrombosis: Evaluation of Nineteen Patients

Objective: Cerebral sinus venous thrombosis (CSVT) is a disease that can be seen in all age groups with various clinical findings and usually a good prognosis. In this study, evaluation of the complaints on admission, the possible risk factors, localization, findings and treatment approaches, and discussion of these findings with comparison to the literature were aimed. Materials and Methods: The demographic, clinical, laboratory and the radiological characteristics of 19 patients with diagnosed with CSVT and followed at the Sakarya University Training and Research Hospital Clinic of Neurology. Results: Nineteen patients (15 female, 4 male) with the diagnosis of CSVT were included. The mean age of the patients was determined as 31.3±11.2. Headache was determined to be the first symptom on admission in 17 patients. Nauseavomiting (n=10), blurred vision (n=4) and epileptic seizures (n=3) had accompanied headache. Altered state of consciousness (n=2), papilledema (n=4), dysarthria (n=1), and cerebellar disorder (n=1) were determined. Two of the patients were pregnant and 6 patients were in the postpartum period. CSVT due to infection was determined in 2 patients. No reason for etiological investigation was found in 4 of the cases. In 11 patients, more than one etiology were detected. Two patients had been diagnosed with Behçet’s disease. MTHFR A1298C gene heterozygous mutation was most detected. Fourteen patients were determined to have a single sinus venous thrombosis and 5 patients had more than one sinus venous thrombosis on magnetic resonance venography. Six patients had venous infarction. Conclusion: Pregnancy and postpartum period are significant risk factors for CSVT. The association of more than one reason in the etiological investigations of patients despite the presence of one significant risk factor has been emphasized.
