[Removal of the endocardial pacemaker leads--experience with 16 leads in 10 patients].
Recent advances in pacemaker leads have contributed to the improvement of their stability at the anchored sites. However, we sometimes have difficulty in removing them. We have experienced the removal of 16 leads in 10 patients (male: 7, female: 3) in the last 5 years. The age of patients ranged from 48 to 87 years, and the average was 60. The reasons for the removal were as follows; pocket infection in 6 cases, sepsis in 1 case, ischemic skin erosion in 1 case, retained fractured ventricular lead in 1 case, fracture of Accufix atrial lead in 1 case. The methods of removal consisted of using the removal kit, the snare or the basket snare transvenously, direct surgical approach or a combination of them. We used the removal kit alone in 12 electrodes (6 atrial, 6 ventricular), and removal of 5 atrial and 3 ventricular leads were successfully by this method only. The removal of 4 leads by kits alone failed, so that 2 ventricular leads were removed transvenously, one atrial and one ventricular lead were removed surgically, and 1 ventricular lead was left untreated. Finally, we were able to remove 15 of 16 leads (93.3%) successfully. This experience indicates that these interventions should be performed as less invasively as possible, yet we should give an explanation to the patients as to the options we may employ when we have failed in the intended procedure.
