Transvenous extraction of 3-year-old Seldinger guide wire lost in venous system and causing superior vena cava syndrome - rare complication of implantable cardioverter-defibrillator implantation.

A 65-year-old male patient underwent left-sided placement of implantable cardioverter-defibrillator. At three years after implantation he emerged complaining on left upper limb and left-sided neck edema. Left brachicephalic vein thrombosis due to device leads was recognized. The attending cardiologist referred the patient to university radiology department for venous angioplasty but the patient was admitted to cardiology department. Coronary angiography was performed due to suspicion of ischemic heart disease. However, it showed the presence of foreign body in cardiovascular system - completely intravascular round-tipped guide wire used in Seldinger technique for insertion of the endocardial lead abandoned in left subclavian vein and reaching to superior vena cava. Patient was transferred to third-degree reference lead extraction center. The procedure was performed under general anesthesia in hybrid operating room. Via femoral vein access we introduced Needle's Eye Snare and grasped the guide wire. Then, using polytetrafluoroethylene sheath the tissue adhesions were dissected and the complete guide wire was retrieved.
