Background and Objectives:Venous sinus thrombosis is a rare cerebrovascular disorder with different geographical and age distribution. The prevalence of this diseaseis5 personsper millionperyear, and has various risk factors. This study aimed to identify the prevalenceof cerebral venous thrombosis and its associatedsymptomsinSanandaj.

Methods:In thisdescriptive study,allpatientswith suspected cerebralvenous thrombosis whohad beenhospitalized atTohidHospital in Sanandaj (referral hospital of the province)during the years2010-2011, were investigated. After data collection from the patients’ medical records, they were analyzedusingdescriptive statistics.

Results:In this study, 24 (80%) out of 30 patients were female, and the mean age was calculated 36.2±13.7 years. Twenty-six subjects (86.7%) had headache. The most common clinical finding was reported to be the left hemiparesis in 10 cases (33.3%), followed by papilledema in 9 (30%). Involvement of upper sagittal sinus was observed in 25 subjects (83.3%) and right transverse sinus in 9 subjects (30%), respectively. The most commonly involved site was right brain hemisphere, and one patient (3%) was died.

Conclusion:The results of this study showed that the high prevalence of cerebral venous sinus thrombosis in women compared to men can be a sign of association of this disease with risk factors, such as OCP, pregnancy, and puerperium. Also, involvement of the right brain hemisphere was more common, for which no explanation was found and further studies are needed.
