Central venous catheter fracture leading to TPN extravasation

"We present a case utilizing contrast-enhanced ultrasound (CEUS) at the bedside to assess catheter integrity in a critically ill infant with a large intra-abdominal fluid collection" Cahill et al (2020).

Abstract:

Central venous lines may require contrast injection under fluoroscopy to evaluate for dysfunction such as occlusion, fibrin sheath development or catheter fracture. Rarely, some patients may be too ill to travel to the interventional radiology suite for this examination. We present a case utilizing contrast-enhanced ultrasound (CEUS) at the bedside to assess catheter integrity in a critically ill infant with a large intra-abdominal fluid collection. CEUS demonstrated extravasation into the collection, confirming catheter fracture and prompting immediate cessation of line use and recommendation for exchange. This case shows the utility of CEUS to evaluate central venous access devices in children who are unable to travel to interventional radiology for a standard contrast injection.
