Vascular Consequences: A Case Report on Posterior Circulation Infarction as a Sequela of COVID-19.

This case report presents a posterior circulation infarction in a previously healthy 39-year-old male, three months post-severe COVID-19. He presented with right-sided homonymous hemianopia and elevated inflammatory markers and D-dimer levels. Imaging revealed an acute left occipital infarct. Such post-COVID-19 posterior circulation strokes are rare. This report discusses the pathophysiology, optimal anticoagulation therapy for COVID-19-related thrombotic complications, and early predictor models. This case underscores the need to recognize thromboembolic events as potential late sequelae in severe COVID-19 cases.
