# Wandering Carotid Artery in Carotid Artery Stenting

## TL;DR

This paper reports a rare case where a carotid artery moved during stenting but returned to its normal position afterward.

## Contribution

The paper presents a novel clinical observation of a wandering carotid artery during and after stenting.

## Key findings

- The right internal carotid artery migrated medially into the retropharyngeal space during stenting.
- Post-stenting imaging showed the artery returned to its original position.
- The positional change was temporary and resolved after the procedure.

## Abstract

A wandering carotid artery is the rare phenomenon of the repeated migration of the carotid artery into the lateral and retropharyngeal spaces. We report a case of wandering carotid artery before and after carotid artery stenting (CAS). The patient was an 82-year-old female with symptomatic right internal carotid artery (ICA) stenosis. A diagnostic digital subtraction angiography (DSA) showed that while the positional relationship between the internal and external carotid arteries was typical, the right ICA had moved medially into retropharyngeal space during CAS. Magnetic resonance angiography a day after CAS showed that the ICA had returned to its original position.
