SUMMARY: Lead orientation was analyzed in 100 consecutive patients (198 Cartesia BSc leads). Different anatomical targets and intraoperative setups were compared. Results: Deviations of up to 90° from the intended implantation direction were observed. Deviations of more than 30° were …
SUMMARY: 9 patients who had been proficient swimmers even after their PD diagnosis lost their ability to swim after STN DBS. Otherwise they had good effect of DBS even on gait. The authors speculate that maybe DBS affects the supplementary …
SUMMARY: A female patient with left-dominant Parkinson’s disease with motor fluctuations and dyskinesias and comorbid long-standing, pharmacologically refractory, and severe postherpetic neuralgia (PHN) underwent a right-sided pallidotomy. Besides a substantial improvement in her Parkinson’s symptoms, she reported an immediate and …
SUMMARY: Here LFPs were recorded from the GPi in 9 dystonia patients when stim was off, showing correlation between low frequency activity (3-12 Hz) and symptom severity. Beta band activity (13-30Hz) did not show such correlation. The authors conclude that …
SUMMARY: In 12 patients with STN DBS who had a special IPG called “Activa PC + S” (that allows recording of LFP) the authors could record LFPs On and OFF med at 8 months after surgery showing that beta activity …
SUMMARY: This is a case of severe MRI visible massive peri-electrode edema on one side stretching down to the STN. This appeared only 4 days after surgery when the patient developed lethargy and mild confusion in absence of fever or …
SUMMARY: The authors retrospectively evaluated 43 patients with PD who received bilateral STN-DBS. The volumes of activated tissue were analyzed to obtain significant stimulation clusters predictive of 4 clinical outcomes: improvements in bradykinesia, rigidity, tremor, and reduction of dopaminergic medication. …
SUMMARY: EARLYSTIM has been very advertised since the paper published in NEJM in 2013. Kim et al argue that “despite of more benefit from DBS surgery than best medical therapy in early stage of PD, we need to consider the …
SUMMARY: The authors reviewed 58 articles to explore the similarities and differences between “awake” and “asleep” DBS techniques. The surgical procedures, clinical outcomes, costs and complications of each technique were compared in detail through literature review. The results demonstrated that …
SUMMARY: The authors describe a patient in whom STN DBS implantation based on one MER pass resulted in good response at 1 mA but sustained dysarthria at 2 mA, suggesting a slightly anteriorly located electrode. Instead of lead adjustment and …
