Management of a Fragmented Angiocatheter During Central Venous Cannulation: A Case Report and Important Lessons

Complications during central venous catheter (CVC) insertion are infrequent with an incidence of 0.1%-1%. We experienced a rare CVC complication with fragmentation of the angiocatheter at its hub during central venous cannulation while utilizing the modified Seldinger technique (ie, wire through the catheter technique). Vascular surgery was emergently required to remove the catheter fragment from the neck. Clinicians must remain vigilant during all aspects of CVC insertion, including awareness of the potential for fragmentation of the angiocatheter during its removal over the in situ guidewire. Prompt recognition and appropriate management included leaving the guidewire in place (to stabilize the distal fragmented segment) and promptly consulting vascular surgery for removal before potential vascular embolization of the angiocatheter fragment. We further recommend that all components of the insertion kit be inspected before and after patient use.
