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

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.
