# Endovascular Retrieval of a Peeled-Off Fragment of a Hydrophilic Guidewire Embolized Into the Pulmonary Artery Using a Unique Loop-Snare Torque-Entanglement Technique

## TL;DR

A new technique was developed to remove a hydrophilic guidewire fragment from the pulmonary artery using a loop-snare method.

## Contribution

A novel loop-snare torque-entanglement technique was introduced for retrieving embolized guidewire fragments.

## Key findings

- The loop-snare torque-entanglement technique successfully retrieved a peeled-off guidewire fragment from the pulmonary artery.
- Traditional endovascular methods failed due to the lack of a free edge on the foreign body.
- The described technique offers a solution for retrieving difficult foreign bodies in vascular interventions.

## Abstract

Pulmonary vascular embolization of the stripped coating of a hydrophilic guidewire is a rare complication. Endovascular retrieval is preferred over surgical treatment or conservative management. Most of the commonly used endovascular retrieval techniques fall short when the foreign body does not present a free edge to grab. There are a few innovative techniques that can be applied to retrieve such difficult foreign bodies. This case report describes a unique loop-snare torque-entanglement technique for the retrieval of such a foreign body out of the pulmonary vasculature.
