Catastrophic cases of thrombosis have occurred due to COVID vaccine in association with thrombocytopenia and antibodies against PF4 (platelet factor 4); catastrophic syndrome has been named vaccine-

induced immune thrombotic thrombocytopenia (VITT); ischemic stroke can be the symptom onset of vaccine-induced immune thrombotic thrombocytopenia or can complicate the course of the disease'

‘In this review, we provide an overview of stroke and cerebrovascular disease as a complication of the SARS-CoV-2 infection and outline the main clinical and radiological characteristics of cerebrovascular complications of vaccinations, with a focus on vaccine-induced immune thrombotic thrombocytopenia.’
