Insights
Central venous catheter fragments broke off and lodged in the right atrium in two patients. Both fragments were successfully retrieved using the Dotter intravascular retriever catheter, highlighting the importance of radio-opaque catheters.
Area of Science:
- Cardiology
- Vascular Surgery
- Medical Device Technology
Background:
- Central venous catheters are essential for long-term venous access.
- Catheter fragment embolism is a rare but serious complication.
- Radio-opaque central venous catheters are used to facilitate visualization.
Observation:
- Two cases are presented where large fragments of transvenously placed central venous catheters fractured.
- These fragments migrated and became lodged in the right atrium.
- Staphylococci were cultured from the retrieved catheter fragments.
Findings:
- Successful percutaneous removal of right atrial catheter fragments was achieved using the Dotter intravascular retriever catheter introduced via the femoral vein.
- The Dotter intravascular retriever catheter proved effective for retrieving intravascular foreign bodies.
- The presence of staphylococci suggests potential catheter-related bloodstream infection.
Implications:
- This case series underscores the utility of the Dotter intravascular retriever catheter for managing central venous catheter fragment complications.
- The findings reinforce the critical importance of using radio-opaque central venous catheters for improved intraprocedural monitoring and complication management.
- Prompt diagnosis and intervention are crucial for favorable patient outcomes in cases of catheter embolism.
Abstract:
Despite all precautions in two cases a large fragment of a transvenously placed central-venous catheter broke off and became lodged in the right atrium. In both the fragments were removed successfully and without complication with the Dotter intravascular retriever catheter, percutaneously introduced into the femoral vein. Staphylococci were grown from both catheter fragments after removal. These cases illustrate once again the value of radio-opaque venous catheters.
