Purpose: Recent data suggest how adverse events occur more frequently after Implantable Pulse Generator (IPG) replacement than during the deep electrode positioning in patients treated with Deep Brain Stimulation (DBS). For instance, erroneous extension adjustment to change in laterality and inaccurate lead connection represent problems, which strongly affect patients outcome. We analyzed our data after 13 years of IPG replacement. Materials and Methods: We treated 107 patients (83 PD and 24 Dystonia) with DBS in 13 years. The Dual Channel IPGs replaced during this period were 91. 25 patients needed more than one replacement, especially among the dystonic population. During surgery, we temporarily marked in all the cases the right extension lead before the disconnection from the exhausted IPG. Good impedances were intraoperatively checked in all the cases. Results: Our surgical technique allowed us to avoid any erroneous change in laterality or abnormal impedances due to a suboptimal connection to the IPG. The mean duration of the operation was 25 min and a quick postoperative restart of DBS was possible in all the cases. Stability of symptoms after IPG replacement was achieved in all the patients, with an accurate clinical management within the first 48-72 postoperative hours. Conclusion: Our surgical and postoperative management demonstrates how to avoid some important adverse events with some easy steps, without any discomfort for the patients in terms of duration of surgery or longer hospitalization. Thus, stability of symptoms after the IPG replacement may be easily guaranteed during the first postoperative period.
