title: [Cerebral venous sinus thrombosis: Epidemiology, clinical characteristics, imaging and prognosis].
abstract: BACKGROUND
  Cerebral venous sinus thrombosis represents 0.5 - 1% of all cerebrovascular diseases.
  
  
  OBJECTIVE
  The aim of this study was to determine the epidemiological, clinical, and imaging features of the disease, as well as the outcomes of patients with cerebral venous sinus thrombosis, and to explore the characteristics associated with unfavorable patient outcomes.
  
  
  METHODS
  In this cross-sectional, retrospective study, the medical records of 37 patients with cerebral venous sinus thrombosis were analyzed.
  
  
  RESULTS
  Eighty-six percent of the patients were women, and the mean patient age was 41 years. The most frequently reported symptom was headache (86.5%); headache was the single presenting symptom in 40.5% of the patients. Sixty-eight percent of the patients had at least one risk factor, the most frequent of which was obesity (24.3%). A total of 43.2% of the patients had no focal neurological findings. The most common finding on computerized tomography (CT) was hyperdense venous sinuses; on Magnetic Resonance Imaging (MRI), the most common finding was venous infarction. On average, 2.27±1.3 sinuses were involved; most frequently, the transverse venous sinuses were affected. The average hospital stay was 7.8±3.6 days. At hospital discharge, the outcomes were favorable in 92% of the patients, and the mortality rate was 5.4%.
  
  
  CONCLUSIONS
  Cerebral venous sinus thrombosis is a different type of cerebrovascular disorder, with distinct epidemiology, risk factors, clinical presentations and functional outcomes. The diagnosis is based on clinical suspicion because of the unspecific clinical presentation of the disease.
