Conclusion: While this is an unusual presentation of cerebral edema following DBS placement, ultimately, the outcome was good similar to other reported cases. Supportive care and corticosteroids remain the treatment of choice for this phenomenon. PMID: 33024597 [PubMed]
Conclusion: Both methods for measuring rotation angles led to comparable results and can be used interchangeably. Directional stimulation settings can safely be initiated after the first postoperative day, without risking subsequent lead rotation-related anatomical shifts.Stereotact Funct Neurosurg
ConclusionThe present study confirmed that GPi-DBS is an effective treatment in patients with advanced PD, owing to metabolic changes in the areas involved in motor execution. The absence of relative metabolic decrease in the limbic circuit and the few changes affecting the associative circuit could explain why GPi-DBS is cognitively safe.
Conclusion: Given the millimetric size of stereotactic targets and electrodes, lead implantation for neuromodulation therapy needs to be accurate. We demonstrate that 3-T imaging could not be used for stereotaxy in our MRI-guided direct targeting protocol because of a risk of error induced by distortion.Stereotact Funct Neurosurg
Conclusions: Caution is advised in fusing intraoperative OAO2 images directly to preoperative MRI without a preoperative CT as the reference exam for image fusion, as the specific fusion algorithm employed may unpredictably affect targeting accuracy.Stereotact Funct Neurosurg
CONCLUSIONS: MRgFUS thalamotomy is a cost-effective treatment for patients with TDPD, particularly over continued medical therapy. While MRgFUS remains competitive with DBS, the cost-effectiveness advantage is less substantial. These results will help inform the integration of this technology in the healthcare system.

Conclusion: The association between ICA volume and translocation of the DBS electrode is small in magnitude and not clinically relevant for DBS cases within a normal range of postoperative subdural air volumes. Differences in proximal lead bowing observed between DBS leads may reflect hardware engineering subtleties in the construction of DBS lead models.Stereotact Funct Neurosurg
Conclusion: The MicrotableTM platform is capable of submillimetric accuracy in patients undergoing stereotactic surgery. It has achieved clinical efficacy in our patients without surgical complications and has demonstrated the potential for superior accuracy compared to both traditional stereotactic frames and other common frameless systems.Stereotact Funct Neurosurg
15Introduction: The ventral intermediate nucleus (VIM)/dentato-rubro-thalamic bundle (DRT) has been described as a relevant target for tremor control. However, up to 20% of patients with deep brain stimulation (DBS) of the VIM/DRT for essential tremor develop a stimulation-induced cerebellar syndrome, which is difficult to treat and has relevant effects on quality of life. While the exact cause is elusive, it is hypothesized that the (supratherapeutic) co-stimulation of cerebellar output pathways in addition to the DRT and antidromic stimulation of the cerebellum plays a crucial role. Methods: For this study, 8 patients wh...
341Background: With the advance of subthalamic nucleus (STN) deep brain stimulation (DBS) in the treatment of Parkinson’s disease (PD), it is desired to identify objective criteria for the monitoring of the therapy outcome. This paper explores the feasibility of metabolic network derived from positron emission tomography (PET) with 18F-fluorodeoxyglucose in monitoring the STN DBS treatment for PD. Methods: Two cohorts with PET imaging were recruited for this study. The cohort I, including 33 PD patients and 33 healthy controls (HCs), were used for the establishment of the PD-related metabolic network pattern (PDRP). ...
