Session Title: Neuroimaging
Session Time: 1:15pm-2:45pm
Location: Les Muses Terrace, Level 3
Objective: To comprehensively compare the use of IMG-DBS, PHY-DBS and COMB-DBS in treating PD.
Background: Deep brain stimulation (DBS) is a well-established surgical therapy for Parkinson’s disease (PD). Intraoperative imaging (IMG), intraoperative physiology (PHY) and their combination (COMB) are the three mainstream DBS guidance methods.
Method: PubMed, Embase, the Cochrane Library and OpenGrey were searched to identify PD-DBS studies reporting guidance techniques published between January 1, 2010 and May 1, 2018. We quantitatively compared the therapeutic effects, surgical time, target error and complication risk and qualitatively compared the patient experience, cost and technical prospects. A meta-regression analysis was also performed. This study is registered with PROSPERO, number CRD42018105995.
Results: Fifty-nine cohorts were included in the main analysis. The three groups were equivalent in therapeutic effects and infection risks. IMG-DBS (p < 0.001) and COMB-DBS (p < 0.001) had a smaller target error than PHY-DBS. IMG-DBS had a shorter surgical time (p < 0.001 and p = 0.008, respectively) and a lower intracerebral hemorrhage (ICH) risk (p = 0.013 and p = 0.004, respectively) than PHY- and COMB-DBS. The use of intraoperative imaging and microelectrode recording correlated with a higher surgical accuracy (p = 0.018) and a higher risk of ICH (p = 0.049).
Conclusion: The comparison of COMB-DBS and PHY-DBS showed intraoperative imaging’s superiority (higher surgical accuracy), while the comparison of COMB-DBS and IMG-DBS showed physiological confirmation’s inferiority (longer surgical time and higher ICH risk). Combined with previous evidence, the use of intraoperative neuroimaging techniques should become a future trend.
