Insights
Catheter emboli pose significant risks, necessitating removal. While percutaneous extraction is preferred, surgical removal may be required, though complete extraction of embolized fragments isn't always feasible.
Area of Science:
- Cardiovascular Medicine
- Interventional Radiology
Background:
- Catheter emboli represent a serious complication in patient care.
- A high complication rate (49%) underscores the need for effective management strategies.
Abstract:
Catheter emboli are a significant risk to patient well-being. With a 49% complication rate for indwelling catheter emboli, the consensus is that these foreign bodies should be removed. Preferably, the emboli are removed by percutaneous extraction; however, if the emboli are in the heart or central vasculature and percutaneous extraction fails, then thoracotomy with operative removal is necessary. We analyze the literature on catheter emboli and present a case showing that extraction of embolized fragments is not always possible.
