ABSTRACT

Background: Venous sinus thrombosis accounts for 1% of cerebral vascular events; its incidence is 5 cases per million population and its mortality is 10%. The superior sagittal and transverse venous sinuses are the most affected. Pregnancy is a special risk factor since thrombosis is registered in 0.01% of pregnancies.
Clinic case: A 40-year-old primigravida patient with a 33.6 week biamniotic twin pregnancy. She was admitted to the Emergency Department due to the diagnosis of preeclampsia with severity criteria, with blood pressure of 160-100 mmHg and transaminasemia. She was prescribed antihypertensive treatment and intravenous magnesium sulfate. It was decided to terminate the pregnancy by cesarean section. On the fourth post-cesarean day she had decreased strength in both arms, loss of muscle tone in the pelvic limbs, holocranial headache and altered alertness (Glasgow of 14). Magnetic resonance imaging showed occlusion of the superior longitudinal sinus and ischemia in the left parietooccipital region. He was administered anticoagulants and analgesics with which he evolved adequately; he was discharged without complications.
Conclusions: Venous sinus thrombosis implies a challenge when there is no high diagnostic suspicion in patients with neurological signs and symptoms and, even more so, when prothrombotic risk factors are added, such as pregnancy and puerperium. Timely diagnosis provides the opportunity to initiate appropriate treatment and reduce symptoms and comorbidities.
