Nonsurgical retrieval of intra-cardiovascular catheter fragments

Migrated intra-cardiovascular fragments from broken catheters were retrieved transvenously in 6 cases. In all of these cases, the catheters had been used for total parenteral nutrition. The catheter fragments were lodged in the pulmonary artery in 3 cases and in the right atrium in the others. A basket-type grasping forceps modified for this retrieval technique was inserted via the subclavian vein, femoral vein or basilic vein percutaneously. The migrated catheter fragments were removed successfully without any clinical complications in all 6 cases. Appropriate evaluation of the lodging site and length of the fragment, and careful examination of general condition should be carried out prior to this procedure. This noninvasive maneuver is simple, safe and reliable, and can be promptly. It is considered to be a reliable method of choice in cases of migrated catheter fragment.
