Abstract:

Introduction: Although not a prevalent disease, cerebral venous thrombosis (CVT) has been considered relatively morbid. There is little research about CVT in Iran, but it is more likely during pregnancy and puerperium. Therefore, we conducted this study to determine the incidence and risk factors during pregnancy. Methods: Twenty-eight patients were selected from the hospital archives. The files of pregnant patients who were diagnosed as CVT and who were admitted to the hospital between April 2015 and March 2018 were studied for demographic and gestational information. Statistical methods and software were utilized. Results: The incidence of CVT was 14.52 cases per 100.000 pregnancies. Less than one third of the cases occurred in the postpartum period with a mean disease age higher than the pregnancy period. Immobility, primiparity, 0 Rh+ blood type or consanguineous marriage was found in most of the cases. Past medical histories were positive in 11 cases. Caesarean delivery or onset in the first postpartum week was found in most of the postpartum cases. magnetic resonance imaging managed to diagnose all cases, while computed tomography scan failed to do so. CVT was in the transverse sinus in most of the cases. Conclusion: The study reveals some risk factors for CVT, such as immobilization, chronic hypertension, preeclampsia and caesarean section.
