With great interest, we read the article entitled “Salvage of Infected Left Ventricular Assist Device with Antibiotic Beads.”1 We were deeply impressed by the authors’ successful work in treating 26 patients with left ventricular assist device infections using antibiotic beads. Similarly, our team treated eight patients who suffered deep brain stimulation hardware exposure from 2011 to 2013. In five of these patients, the problems were successfully resolved by débridement and local flap transfer with or without skin graft. Three patients suffered wound dehiscence again and underwent hardware removal.
Deep brain stimulation has been widely applied to patients with movement disorders such as Parkinson disease, essential tremor, dystonia, and others. However, hardware-related complication rates of postoperative incision infection and skin erosion were reported to vary from 7.8 to 26 percent.2–5 It was reported that skin erosion mostly occurred at the connector site. In our case series, five patients suffered frontal area exposure of the burr-hole cap, two suffered postauricular skin erosion, and one suffered chest wall infection. It is difficult to place antibiotic beads in these areas; however, scalp and muscle flaps are believed to have the ability to withstand infection because of their rich blood supply. There are three main arteries adjacent to the area where the deep brain stimulator was inserted: the occipital artery, the temporalis superficial artery, and the thoracoacromial artery (Fig. 1). All of these arteries could be used as the dominant vessel for an island or local flap. Thus, to keep a lifeboat in case the patient suffers hardware exposure, the integrity of these three arteries should be maintained during deep brain stimulator insertion.
An antibiotic-covered catheter was also reported to protect deep brain stimulator leads after infection, with a decreased risk of deep brain stimulator lead damage.5 Compared with the antibiotic-impregnated catheter, local flap transfer is inexpensive and easy to perform. Our preliminary clinical experience in this report indicates its effectiveness (Fig. 2).
