Background Thrombotic conditions are common complications during pregnancy. Cerebral venous thrombosis is also more frecuent in pregnant patients, with a prevalence of 4.5 per 1000 obstetric admissions. We present 3 cases that were managed in our unit. Patient 1 38‐year‐old, epileptic, 10 week pregnant. She had occipital, pulsatil headache plus blurred vision. A Magnetic Nuclear Resonance (MNR) showed lack of flow, in the right transverse sinus, and yugular gulf. Patient 2 32‐year‐old, with an haemolytic anemia and an occipital meningioma. She had a 34‐weeks pregnancy and was admitted because of edema of the lower extremities. She has paresthesies and hypoesthesia of the right leg, which progresed to anesthesia. MNR showed her occipital tumor, measuring 10 × 12 mm, and thrombosis of the right transverse and lower sagital sinus. Patient 3 30‐year‐old, 10 weeks pregnant, admitted because of a headache that did not respond to common analgesics. MNR informed thrombosis of the left transverse sinus, and the yugular gulf. All 3 patients were treated with low molecular weight heparin. Conclusions The majority of cases of cerebral venous thrombosis involve the high sagital sinus. In the pregnant patient study by images is recommendable and the test of choise is MNR, which has a sensibility of 90%. Recommended treatment is anticoagulant therapy.
