First Report of Cerebral Venous Thrombosis Following Inactivated-Virus Covid Vaccination (Sinopharm and Sinovac)

      Abstract

      Cerebral venous thrombosis (CVT) is an uncommon cerebrovascular disease, which has been reported with covid infection as well as covid vaccines, particularly AstraZeneca and Janssen vaccines. We present four consecutive cases of CVT after receiving either Sinopharm or Sinovac vaccine, both of which are composed of an inactivated-virus. All the patients recovered well with anticoagulation and discharged with a good functional outcome. This is the first case series reporting CVT following the administration of these vaccines.
