Background
Cerebral venous thrombosis (CVT) is characterized by clinical and etiological polymorphism. In Sub Saharan Africa, few studies have been carried on CVT. The aim of our study is to determine the epidemiological, clinical, radiological and etiological features of CVT across a Senegalese cohort.
Patients and methods
This was a retrospective and prospective study conducted from January 2013 to December 2016 at the Neurology department of Fann teaching hospital, Dakar, Senegal. All the patients hospitalized or followed for CVT were included. The diagnosis was established with neuroimaging (CT-scan and/or MRI).
Results
Thirty patients were collected. The average age was 34 years [10-62]. The sex ratio (M/F) was 0.43. Onset was subacute in 90 % of cases. The average admission extension of time was 37 days [1-8 month]. The main clinical signs were headache (86.7%), vomiting (60 %), hemiplegia (56,7 %), seizures (43,3 %) and fever (33,3 %). Thrombosis of the lateral sinus (46,7 %) and the superior sagittal sinus (33,3 %) was the most common. The location was multiple in 1/3 of the patients. The main etiological factors were mostly gynecological-obstetric. All patients had anticoagulation. The average hospital stay was 21 days [7-47]. The short-term evolution (3 months) was mostly favorable (96.7%).
Conclusion
CVT is a young woman neurological disease. An exhaustive etiological investigation and a longer multicenter study are necessary.
