Incidence rate of cerebral venous thrombosis and its related factors in Kermanshah city in 2009-2010

Cerebral venous thrombosis (CVT) is a rare disorder. Incidence of CVT in developing countries is not clear. This study was conducted to determine the incidence rate of cerebral venous thrombosis, its symptoms and some of its predisposing factors in Kermanshah city. This was a descriptive study. The sample size included 21 cases. Diagnosis of cases of CVT was based on MRI sequences T1, T2, FLAIR and approved by the gold standard MR venography over 12 months. The data were introduced into SPSS software and analyzed by means of descriptive statistics and the frequency of data was calculated. This study included 21 patients; three males (14.3%) and 18 females (85.7%) with a mean age of 36.00±10.13 years who had a total number of 55 thromboses. The most prevalent clinical symptoms, predisposing factor, associated disorder, and sinus involved, included headache (95.2%), OCP consumption (52.4%), infarction (47.6%) and superior sagital sinus (71.4%) respectively. This study showed that the incidence of cerebral venous thrombosis in Kermanshah is relatively higher in comparison to the statistics mentioned in other studies, so further studies for more evaluation of contributing factors in this disease are recommended.
