When Right Is on the Left (and Vice Versa): A Case Series of Glioma Patients with Reversed Lateralization of Cognitive Functions.

J Neurol Surg A Cent Eur Neurosurg 2020 Mar 17;81(2):138-146. Epub 2020 Feb 17.

Department of Neurosurgery, Elisabeth-Tweesteden Hospital, Tilburg, The Netherlands.

We report a case series of four patients operated on for a glioma in awake conditions and in whom task-based functional magnetic resonance imaging (fMRI) demonstrated right-dominant activity during a language production task. Language functional sites were identified intraoperatively by electrical stimulations only in the patient with a right-sided lesion. Furthermore, the pre- or postoperative cognitive evaluations in the three patients operated on for a left-sided glioma revealed right spatial neglect and dysexecutive syndrome, hence demonstrating that, in patients with right-dominant activity on language fMRI, the left hemisphere is implicated in spatial consciousness and cognitive control.

Hemispheric Dominance for Language and Side Effects in Mapping the Inferior Frontal Junction Area with Transcranial Magnetic Stimulation.

J Neurol Surg A Cent Eur Neurosurg 2020 Mar 11;81(2):130-137. Epub 2020 Feb 11.

Department of Neurosurgery, Medical Faculty, RWTH Aachen University, Aachen, Germany.

Background And Study Aims:  Language mapping by navigated transcranial magnetic stimulation (TMS) is commonly applied over the left language-dominant hemisphere to indicate the language-related cortex. Detailed language mapping of Broca's region including stimulation targets in the immediate vicinity to the premotor cortex may raise concern about confounding unspecific motor effects. We performed interhemispheric comparisons to delineate such possible unspecific effects from true TMS-induced language inhibition. Read More

1 Hz Repetitive Transcranial Magnetic Stimulation of the Primary Motor Cortex: Impact on Excitability and Task Performance in Healthy Subjects.

J Neurol Surg A Cent Eur Neurosurg 2020 Mar 11;81(2):147-154. Epub 2020 Feb 11.

Department of Neurosurgery, Charité Universitatsmedizin Berlin, Berlin, Germany.

Objective:  Neuronavigated repetitive transcranial stimulation (rTMS) at a frequency of 1 Hz was shown to reduce excitability in underlying brain areas while increasing excitability in the opposite hemisphere. In stroke patients, this principle is used to normalize activity between the lesioned and healthy hemispheres and to facilitate rehabilitation. However, standardization is lacking in applied protocols, and there is a poor understanding of the underlying physiologic mechanisms. Read More

Safety of Prophylactic Heparin in the Prevention of Venous Thromboembolism After Spontaneous Intracerebral Hemorrhage: A Meta-analysis.

J Neurol Surg A Cent Eur Neurosurg 2020 May 21;81(3):253-260. Epub 2020 Jan 21.

Departments of Neurology, The First Affiliated Hospital of Soochow University, Suzhou, Jiangsu, People's Republic of China.

Objectives:  Patients with spontaneous intracerebral hemorrhage (sICH) have a nearly fourfold greater risk for venous thromboembolism (VTE) than those with acute ischemic stroke, and VTE after sICH is associated with high risk for in-hospital mortality. The benefit from prophylactic heparin for VTE remains uncertain because its safety is not documented. In this study, we used an updated meta-analysis to evaluate the safety of heparin for the prevention of VTE in patients with sICH. Read More

Quantitative Sensory Changes Following Gasserian Ganglion Radiofrequency Thermocoagulation in Patients with Medical Refractory Trigeminal Neuralgia: A Prospective Consecutive Case Series.

J Neurol Surg A Cent Eur Neurosurg 2020 Jan 21. Epub 2020 Jan 21.

Department of Neurosurgery, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.

Background And Objective:  Microsurgical vascular nerve decompression and percutaneous ablative interventions aiming at the Gasserian ganglion are promising treatment modalities for patients with medical refractory trigeminal neuralgia (TN). Apart from clinical reports on a variable manifestation of facial hypoesthesia, the long-term impact of trigeminal ganglion radiofrequency thermocoagulation (RFT) on sensory characteristics has not yet been determined using quantitative methods.

Material And Methods:  We performed standardized quantitative sensory testing according to the established protocol of the German Research Network on Neuropathic Pain in a cohort of patients with classical ( = 5) and secondary ( = 11) TN before and after percutaneous Gasserian ganglion RFT (mean follow-up: 6 months).

Single-Stage Clipping of Seven Intracranial Aneurysms in the Anterior Circulation via Unilateral Pterional Approach: A Case Report and Literature Review.

J Neurol Surg A Cent Eur Neurosurg 2020 May 21;81(3):271-278. Epub 2020 Jan 21.

The First Hospital of Jilin University, Neurosurgery, Changchun, Jilin, China.

The occurrence of multiple intracranial aneurysms (MIAs) is not rare, with a reported incidence of 15 to 35%. However, patients harboring seven or more intracranial aneurysms are so uncommon that only sporadic cases have ever been reported. We present a rare case with seven intracranial aneurysms (two anterior communicating artery aneurysms, two right middle cerebral artery aneurysms, two left ophthalmic artery aneurysms, and one right ophthalmic artery aneurysm) in the anterior circulation that were simultaneously clipped via the extended right pterional approach.
