# Acute Occlusion of a Persistent Sciatic Artery in a Patient with COVID-19 Infection

## TL;DR

A rare case of a blocked sciatic artery in a man with COVID-19 was successfully treated with surgery.

## Contribution

This case report highlights a rare vascular complication of COVID-19 and its successful surgical management.

## Key findings

- Acute occlusion of a persistent sciatic artery was diagnosed in a patient with COVID-19.
- Conservative treatment failed, leading to toe necrosis.
- Distal artery bypass successfully treated the condition.

## Abstract

Persistent sciatic artery (PSA) is an exceptionally rare vascular condition that occurs in approximately 0.025%–0.04% of the general population. We describe the case of a 51-year-old man who presented with acute left lower limb pain and high fever. He was diagnosed with COVID-19 and isolated, and conservative treatment was performed for toe pain, resulting in left toe necrosis. Computed tomography revealed PSA occlusion in the left lower extremity. We diagnosed the patient with acute occlusion of the PSA due to COVID-19. The complicated disease was successfully treated using distal artery bypass.
