Catheter fragment retrieval

Extract:

“A fragmented intravascular device can be retrieved either through conventional open thoracotomy or minimally invasive percutaneous endovascular approach, the latter leading to a faster recovery and an overall reduction in morbidity and mortality.[1] These techniques use various percutaneous equipment such as snares, tip deflecting wires and baskets for foreign body retrieval.[7] The most popular among these is the snare, which kinks less owing to its elastic manufacturing. Rarely, thoracotomy is required when both ends of the catheter are either fixed or entrapped, which makes it impossible to grasp. Endovascular retrieval, although requiring adequate facility and expertise, is a safe and feasible option.”
