Vaccine-associated thrombosis has previously been described in patients presenting with cerebral sinus thrombosis, deep venous thrombosis/pulmonary embolism, or mesenteric venous thrombosis. Only recently has arterial thrombosis gained attention. A new entity known as vaccine-induced thrombotic thrombocytopenia (VITT) has been associated with the coronavirus disease of 2019 (COVID-19) vaccines produced by AstraZeneca and Johnson & Johnson. We describe a case series of three patients who presented with acute limb ischemia with vaccine-associated arterial occlusions, one of whom was diagnosed with VITT.
