... (ET), and dystonia. Treatment efficacy is dependent on stereotactic accuracy of lead placement into the deep brain target of interest. However, brain shift attributed to pneumocephalus can introduce unpredictable inaccuracies during DBS lead placement. This study aimed to determine whether...

... between January 2015 and December 2018. Intracranial air (ICA) can accumulate in the subdural space between the cranium and the brain during DBS surgery and is an indicator of brain shift, which is defined as the movement of brain tissue relative to its natural anatomical position within...

... Pneumocephalus Parkinson’s disease Essential tremor Brain shift Deep brain stimulation (DBS) implantation surgery has been associated with a variety of complications, some of which are irreversible [ 1 ]. The most serious complication resulting from DBS lead insertion is an intracerebral hemorrhage...

... pneumocephalus, thus decreasing brain shift during implantation. Objective: To compare the incidence and volume of pneumocephalus during awake (wkDBS) and aDBS procedures. Methods: A retrospective review of bilateral DBS cases performed at Oregon Health & Science University from 2009 to 2017 was undertaken...

... extremes. 17 02 2016 18 10 2016 14 1 2017 [email protected] Among multiple potential causes of electrode targeting error, brain shift has been implicated as a significant contributor, resulting in extensive efforts to mitigate its occurrence [ 7,8,9,10 ]. First described...

... approach the MRI-planned target on the medial-lateral axis. Conclusion: There was more electrode adjustment needed on the second side, possibly in relation with brain shift. We thus suggest performing a single central track with electrophysiological and clinical assessment, with multidirectional...

...Daniel R. Kramer; Casey H. Halpern; Shabbar F. Danish; Jurg L. Jaggi; Gordon H. Baltuch Background: Brain shift during deep brain stimulation (DBS) surgery may compromise target localization. Loss of cerebrospinal fluid is believed to be the underlying mechanism, thus an intraventricular trajectory...

... the effect of brain shift on the estimation of the electrode placement error (EPE) for a stereotactic platform in the absence of intraoperative imaging data, and we apply it to the StarFix microTargeting® Platform (FHC Inc., Bowdoin, Me., USA). This method involves comparing the intraoperative stereotactic...

... but can be degraded by intraoperative brain shift. We present the implementation of deformation modeling for brain shift compensation in protoporphyrin IX FGR, integrating these two sources of information for maximum surgical benefit. Methods: Two patients underwent FGR coregistered with conventional...

... microelectrode and/or macroelectrode tracks and decrease implantation accuracy. We studied 25 subjects that underwent DBS surgery and analyzed brain shift between pre-operative and post-operative 3D MRI scans. Brain shift of up to 4 mm was observed in deep brain structures. On average, the recorded shift...
