# A case of successful catheter removal with ventricular septal defect occluder after accidental misplacement of left subclavian vein catheter into aortic arch

## TL;DR

A case where a misplaced catheter was safely removed using a ventricular septal defect occluder, avoiding serious complications.

## Contribution

A novel method using a ventricular septal defect occluder to remove a misplaced catheter in a noncompressible arterial area.

## Key findings

- The catheter was successfully removed without adverse effects using a ventricular septal defect occluder.
- This approach offers a new solution for catheter misplacement into arteries where traditional methods are ineffective.

## Abstract

Abstract The subclavian vein is one of the most frequently-used approaches for central venous catheterization. However, it demands high technical skills and accurate puncture positioning. In case of accidental misplacement into the artery, it is impossible to achieve sufficient local hemostasis. Moreover, removing the catheter without assistance may lead to severe complications or even death. This paper reports a case of an elderly patient with multiple underlying diseases. After left subclavian vein catheterization accidentally entered the aortic arch, a ventricular septal defect occluder was used to successfully remove the catheter. There were no adverse clinical sequelae after the operation, providing a new solution for the accidental insertion of a catheter into an artery in noncompressible areas.
