Background:
Fixation of the electrode during deep brain stimulation (DBS) surgery is an important aspect of the procedure. We have developed an alternative method for securing leads that utilizes a titanium hemoclip and cement. This technique is described, and the rates of complications are compared to conventional methods of securing leads.
Methods:
A total of 291 DBS operations performed by a single surgeon were retrospectively analyzed. We reviewed medical records to look for complications. We compared rates of complications based on the technique used. Re sults: 9 patients (3.1%) developed surgical site infections (SSIs), 4 (1.3%) with SSI of the internal pulse generator pocket. Of the 5 SSIs around the leads, none occurred with StimLoc and 5 (1.1%) with the novel technique. Eight patients (2.7%) required surgical readjustment of the DBS leads due to suboptimal clinical benefit; all 8 (1.8%) occurred with the novel technique. Four patients (1.4%) had lead fractures, 2 (2.2%) with StimLoc and 2 (0.5%) with the novel technique.
Conclusions:
We described a method for securing DBS leads and showed an acceptable incidence of hardware complications when compared to the conventional method. We feel this technique has improved cosmetic results and should be considered as a method for securing DBS leads.
