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

## TL;DR

A 39-year-old man developed a rare stroke in the posterior brain region three months after severe COVID-19, highlighting the risk of late thromboembolic complications.

## Contribution

Highlights a rare case of posterior circulation infarction as a late complication of severe COVID-19.

## Key findings

- A previously healthy man had a left occipital infarct three months after severe COVID-19.
- Elevated D-dimer and inflammatory markers were observed, suggesting a thrombotic mechanism.
- The case emphasizes the need to monitor for late thromboembolic events in severe COVID-19 patients.

## Abstract

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.
