ABSTRACT
Since the start of vaccination against COVID-19 viral infection using adenovirus-based vector vaccine (eg, The Oxford-AstraZeneca vaccine, using the modified chimpanzee adenovirus ChAdOx1, and the Johnson & Johnson vaccine, using human adenovirus serotype 26), a rare, but potentially life-threatening complication called vaccine-induced thrombotic thrombocytopenia (VITT) was reported. As the number of cases increases every day, with the increase in the number of vaccinated people all over the world, this complication is a concern to the medical field. We report a case on the acute management of a patient who presented to us with life-threatening bilateral pulmonary embolism as a complication of VITT after the first dose of vaccination with Oxford-AstraZeneca vaccine against COVID-19.
