Objective： To analyze the data of the patients with cerebral venous sinus thrombosis（CVST） in pregnancy and puerperium， and to improve the understanding of pregnancies complicated by CVST. Methods：We reviewed and analyzed the records of the pregnant patients who also had a diagnosis of CVST in Ganmei Hospital Affiliated to Kunming Medical University from January 2013 to January 2019， including their general data， clinical manifestations， laboratory and imaging findings， treatment methods and prognosis. Results： Among the 13 patients， 10 were in puerperium， 8 had headache， 5 had elevated D-dimer in laboratory examination， and 11 had abnormalities by CT. All patients were clearly diagnosed by magnetic resonance imaging and magnetic resonance venography. The imaging results showed that 9 cases involved superior sagittal sinus and 8 cases involved transverse sinus， including 8 cases with more than 2 venous sinuses. 9 patients had a good prognosis， and 4 of the 5 surgery patientshad a good prognosis. Conclusion： CVST in pregnancies is more likely to occur in the puerperium. Headache is the most common clinical symptom. The possibility of CVST cannot be ruled out if there is no abnormality in D-dimer. The superior sagittal and transverse sinuses were the most commonly affected cerebral sinuses in the patients with CVST. So， the early diagnosis and selection of appropriate treatment methods can help most patients achieve a better prognosis.
