Sagittal venous sinus thrombosis after cesarean section: a case report

Cerebral venous thrombosis (CVT) is uncommon after cesarean section. Although it can be a leading cause of maternal mortality. CVT may occur during pregnancy because of hypercoagulable states such as preeclampsia، thrombophilias، antiphospholipid antibody syndrome and sepsis. A 31 years old woman G2 Ab1 at 37 weeks gestational age with premature rupture of membrane underwent cesarean section because breech presentation and preeclampsia. Spinal anesthesia was done for emergent cesarean section. On the second day after cesarean section، she developed headache، vomiting، focal neurologic deficits، paresthesia، blurred vision. Brain magnetic resonance imaging (MRI) showed thrombosis in anterior half of superior sagittal sinus. Treatment consisted of anticoagulation. Thrombophilias، pregnancy-related hypertension and cesarean section are the predisposing factors for thromboembolism. Unfractionated heparin and low molecular weight heparin (LMWs) are effective drugs for thromboprophylaxis. It is vital to prevent venous thrombosis to reduce mortality during both intrapartum and postpartum periods. Consideration of cerebral venous thrombosis in similar cases is recommended.
