Removal of embolised catheters using flexible endoscopy forceps

Area of Science:

• Cardiology
• Interventional Radiology
• Medical Device Technology

Background:

• Embolized intravascular foreign bodies, particularly catheters, pose significant risks requiring prompt retrieval.
• Percutaneous removal is the preferred method to avoid open surgery for intracardiac foreign bodies.

Observation:

• Five cases of percutaneous retrieval of embolized catheters from the right heart are presented.
• Flexible endoscopy biopsy forceps were utilized in four cases, successfully retrieving the devices in two instances.
• In challenging cases, a helical wire basket was employed after dislodging the catheter, and a catheter fragment was removed from the pulmonary artery using endoscopy grasping forceps.

Findings:

• Flexible endoscopy forceps, especially W-shape grasping forceps, offer a firm grip and maneuverability around curves, facilitating retrieval.
• The limited maneuverability of standard forceps can be overcome by their large mouth opening.
• Helical wire baskets provide an alternative retrieval method when forceps cannot reach the target device.

Implications:

• Endoscopic retrieval techniques are valuable tools for managing embolized catheters in the heart and pulmonary artery.
• These minimally invasive methods reduce patient morbidity associated with surgical extraction.
• Further development of endoscopic retrieval devices may enhance their efficacy and applicability in complex cardiovascular interventions.
