Right atrial thrombus and superior vena cava syndrome in a child
Insights
Central venous catheter complications like superior vena cava syndrome can persist long after removal. This case highlights intermittent obstruction linked to anemia and elevated cardiac output.
Area of Science:
- Cardiology
- Vascular Surgery
Background:
- Central venous catheterization is a common medical procedure.
- Complications such as right atrial thrombosis and superior vena cava syndrome are known risks.
- These complications typically resolve after catheter removal.
Observation:
- A patient presented with recurrent superior vena cava obstruction 1.5 years post-catheter removal.
- The obstruction was intermittent and associated with elevated cardiac output.
- Anemia was identified as the underlying cause of increased cardiac output.
Findings:
- The patient exhibited delayed-onset, intermittent superior vena cava obstruction.
- Elevated cardiac output due to anemia was the functional cause.
- A non-obstructive calcific right atrial thrombus was also noted.
Implications:
- This case challenges the typical transient nature of catheter-related complications.
- It underscores the importance of considering functional causes like anemia in persistent venous obstruction.
- Highlights the need for thorough investigation beyond the immediate post-procedure period.
Abstract:
Complications of central venous catheterization are well described. They include right atrial thrombosis and superior vena cava syndrome resulting from impaired venous drainage. Such complications are normally observed while the catheter is in place. They are often transient, resolving upon catheter removal. A patient with recurrent signs of superior vena caval obstruction 1 1/2 years after removal of the central venous catheter is described. The obstruction was determined to be intermittent and functionally related to elevated cardiac output due, in turn, to anemia. This patient was also found to have a calcific right atrial thrombus which was not obstructive.
