ABSTRACT
Background: Cerebral venous thrombosis (CVT) is a major cause of stroke in young adults. Is more frequent in women, it may appear related to pregnancy or the use of hormonal contraceptives. Its symptoms are nonspecific, often with a normal neurological examination. Its diagnosis is based on imaging tests and in most cases, if treatment is started early, the prognosis may be favorable. Aim(s): Describe the characteristics of CVT in patients that we have had in our clinic. Method(s): We compiled data from patients with CVT followed up in our hemostasis consultation in the last 6 years. Patient data were collected through hospital medical records. Result(s): We have a series of 15 cases, most of them women (73.3%). The average age of the series is 38.6 years (range from newborn to 64 years). The most frequent symptoms were epileptic seizures in 40% and headache in 33.3%. In 45.5% of women, CVT was related to pregnancy or the puerperium, and in 27.3% of the women it was associated with taking oral contraceptives. Thrombophilia (genetic or acquired) has been found to be involved in 33.3% of cases. The remaining cases were associated with breast cancer (1), trauma (1), severe anemia (1), and SARS-CoV vaccines (1). In two cases (13.3%) decompressive neurosurgery was required. In two cases (13,3%), direct oral anticoagulant (apixaban and dabigatran) were used. In 60% of cases anticonvulsant treatment was associated. In 40% of cases, the evolution was very favorable without sequelae, recurrent headache was found in 53,3% of cases. Conclusion(s): CVT is a rare but important cause of stroke in young adults. CVT it is not easy to diagnose, partly due to its relative rarity, its multiple and various clinical manifestations and interpret correct brain imaging. We must keep it in mind to avoid delay in diagnosis and treatment. (Table Presented).
