[Treatment of iatrogenic transvenous foreign body embolism]
Insights
Retrieving embolized central venous devices is crucial to prevent fatal complications. This study shows successful removal in 24 out of 27 patients, highlighting the importance of active intervention.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Medical Device Complications
Context:
- Embolization of central venous devices (e.g., infusion catheters, hydrocephalus drains, pacemaker leads) can lead to severe, potentially fatal, secondary complications.
- Prompt removal of these embolized foreign bodies is often medically necessary to mitigate risks.
Purpose:
- To evaluate the efficacy and safety of interventions for the removal of embolized central venous devices.
- To describe specific procedural approaches based on the type and location of the embolized device.
Summary:
- A series of 27 patients with embolized central venous devices underwent attempted removal.
- Successful retrieval was achieved in 24 patients (89%).
- Transvenous removal via the internal jugular vein was common for catheters, while thoracotomy was required in 8 cases.
Impact:
- Demonstrates a high success rate for the interventional removal of embolized central venous devices.
- Supports an active treatment approach for diagnosed cases, minimizing patient risk.
- Highlights the safety of these extraction procedures with no reported complications.
Abstract:
Embolization of central venous devices, such as infusion catheters, ventriculo-atrial drains for hydrocephalus or intracardial pacemaker leads, may cause fatal secondary complications. Removal of the embolized foreign bodies is therefore mandatory in the majority of cases. 26 in a series of 27 patients underwent removal procedures which have been successful in 24. The specific approach is described in the different subgroups of embolized foreign bodies. Removal has been achieved transvenously through the internal jugular vein in most instances of embolization of infusion or pressure catheters, using forceps or ureteric stone catheters. Thoracotomy was necessary in 8 patients, twice with with cardio-pulmonary bypass. There were no complications due to interventions for catheter extraction. This experience justifies an active approach to treatment once the diagnosis is established.
