Objective: The gold-standard treatment modality for hemifacial spasm is micro-vascular decompression (MVD) via microsurgery. Recently, endoscopic surgery has been attempted by many surgeons. The present study investigated the feasibility of robotic surgery for MVD to treat hemifacial spasm. Methods: The study was conducted using the da Vinci Xi model, and a three-dimensional model was purchased and applied. The advantages and disadvantages of microsurgery, endoscopic surgery, and robotic surgery were compared. Results: In robotic surgery, the root exit zone can be viewed from various angles by magnifying it, similarly to the endoscope and better than the microscope. However, there is a limit to performing versatile manipulations because various tools are not available. When robotic surgery is used, the camera can be applied more stably and compensate for any tremor in the surgeon’s hand, likely making surgery safer. Conclusion: Currently, the approaches for MVD using robotic surgery are limited in their application. However, when optimal tools are developed, it is expected that they can be applied as an effective treatment modality for MVD to treat hemifacial spasm.

Objective: Neuromodulation is a rapidly growing field of treatment, encompassing implantable and noninvasive technology-based approaches. Focused ultrasound (FUS), a noninvasive method, has the potential to modulate neural activity in deep brain regions with spatial precision based on the penetrance of sound waves into the bone and soft tissue. However, neuromodulation is limited by the inability to confirm modulation in real-time. Electrophysiological technology is required to overcome this limitation. In this study, we aimed to confirm neural activity using Neuropixel electrodes during FUS sonication. Methods: Six male C57BL/6 mice were subjected to ultrasound sonication in the hippocampus. Simultaneously, local field potential (LFP) measurements were performed using Neuropixel electrodes. The experimental groups were divided into three categories: before, during, and after FUS sonication and the measured LFP data were compared between groups. Results: Theta and gamma waves were extracted from the recorded LFP data and compared between the groups. The theta and gamma oscillations changed after FUS sonication compared to before. The theta graph showed significant changes between the pre-and during-treatment groups and between the during-and post-treatment groups (theta: 4–8 Hz, F=23.91, p<0.0001). However, the gamma graph did not show significant changes in any groups (gamma: 30–50 Hz). Additionally, the expression of c-fos, a marker of neuronal activity, increased after FUS sonication. Conclusion: Although further research is needed—including longer follow-up LFP measurements after FUS sonication and the collection of more LFP data— neuromodulation with FUS can be considered usable in other neurological disease models.

Fahr disease, also known as idiopathic basal ganglion calcification, is a rare and genetically heterogeneous neurological disorder. Herein, we report a rare case of Fahr disease presenting with multiple cerebral calcifications. A 63-year-old woman presented with dizziness to a local clinic. Brain computed tomography performed on admission revealed multiple high-intensity lesions in both basal ganglia, both cerebellar hemispheres, and the left frontal lobe. In contrast, brain magnetic resonance imaging (MRI) showed no prominent lesions on T2- and T1-weighted images, and there was no contrast enhancement after gadolinium injection. However, multiple dark signals were detected on gradient echo MRI. The location and radiological appearance of the lesion resembled those of a physiological intracranial calcification, except for asymmetric calcification in both cerebellar hemispheres and the left frontal subcortical white matter. The patient was diagnosed with basal ganglion calcification with multiple cerebral cavernous malformations or, less likely, brain tumors. Through a careful radiological and clinical review, the calcifications were diagnosed as Fahr disease. Follow-up was planned. It is important to consider the presence of multiple intracranial calcifications in the basal ganglia, cerebellum, or deep subcortical white matter as a warning sign for Fahr disease.

Spindle cell lipoma is a subtype of lipoma first defined by Enzinger and Harvey; it accounts for <1.5% of all lipomatous tumors. We present an unusual case of a huge spindle cell lipoma. A 49-year-old man with diabetes mellitus experienced neck pain during sleep because of a huge occipital and upper posterior neck mass that had slowly grown during 4 years. We performed local excision of the tumor, and pathological findings confirmed the diagnosis of spindle cell lipoma measuring 10×9.5×5 cm. There was no recurrence 1 year after the surgery.

Objective: Radiation-induced change (RIC) on magnetic resonance imaging after Gamma Knife radiosurgery (GKRS) for cerebral arteriovenous malformations (AVMs) is not rare. We reviewed patients who underwent GKRS for AVMs and analyzed the results and factors associated with RIC.Methods: We reviewed 189 patients who underwent GKRS for AVMs between October 2002 and August 2017. All patients were followed up for at least 3 years. This study included 111 males and 78 females (mean age, 39.63 years; range, 3–79 years). Nineteen patients underwent pre-GKRS embolization. Seventy-six patients had ruptured AVMs and 113 had unruptured AVMs. We analyzed obliteration and RIC occurrence rates. Several demographic and clinical factors were analyzed to determine the influence of AVM obliteration on RIC occurrence.Results: The overall obliteration rate (OR) was 72.49% (137/189) at the final follow-up. The actuarial OR was 55.5% 36 months after GKRS. The overall RIC occurrence rate was 28.04% (53/189), and the actuarial RIC occurrence rate was 26.8% 24 months after GKRS. The OR showed a statistically significant difference according to AVM rupture (p<0.01) and sex (p<0.01). The RIC occurrence rate was significantly associated with AVM rupture (p<0.01), lesion volume (p=0.04), and treatment volume (p=0.03). Other factors showed statistically non-significant relationships.Conclusion: The overall OR after GKRS for AVMs was comparable to the results of other previous reports. RIC is a common postoperative outcome following GKRS for AVMs. In this study, the OR was higher in ruptured AVMs and male patients, whereas RIC occurred more frequently in larger and unruptured AVMs.

Objective: This study aimed to identify possible predictors of unexpected cardiac arrest (CA) in the neurosurgical ward.Methods: A retrospective review of 24 patients who experienced unexpected CA between December 2012 and March 2022 was conducted. Data on demographics, diagnoses, comorbidities, CA timing, pre-CA vital signs, transfer interval from intensive care unit (ICU) to ward, cardiac rhythm, neurological outcomes, and probable causes were collected. We excluded patients who died in the ICU and those with a do-not-resuscitate order.Results: The average age was 70.3 years. Vascular diseases and head traumas were common diagnoses. About 70.8% of arrests occurred during on-call time and 62.5% took place on weekends. The mean interval between ICU transfer and CA was 13.8±29.7 days, with 54.2% occurring within 4 days and 83.3% within 14 days. Pulseless electrical activity was the most frequent initial cardiac rhythm when CA occurred. Respiratory issues were the leading cause of CA (54.2%), and 91.7% of patients had poor neurological outcomes. Within 48 hours before CA, the average value of the lowest arterial oxygen saturation significantly deteriorated from 95.8±2.9% to 90.1±11.4%.Conclusion: Unexpected CA often occurred on weekends and during night duty. Half of the cases took place within 4 days and over 80% within 2 weeks of transferring from the ICU to the ward, with respiratory problems being the main cause. Greater attention should be given to patients’ breathing patterns during night shifts and weekends, especially within the first 2 weeks after patients leave the ICU.

Objective: Slit ventricle syndrome (SVS) is defined as a slit-like appearance of the lateral ventricles with associated symptoms such as headache, vomiting, or drowsiness. The study investigated the risk factors associated with the incidence of SVS following ventriculoperitoneal shunt surgery.Methods: We retrospectively reviewed the medical records of patients who underwent ventriculoperitoneal shunt surgery from January 2011 to 2019 at a single institution. SVS was diagnosed by a slit-like appearance of the lateral ventricles and a low Evan’s ratio (<0.25) on follow-up radiologic images. Results: SVS was diagnosed in 53 (18.2%) of 292 patients who underwent ventriculoperitoneal shunt surgery. The mean age of patients with SVS (48.3 years; range, 4–85 years) was significantly lower than the mean age of those without SVS (58.4 years; range, 0.5–85 years) (p=0.024). Male patients showed a slightly higher incidence of SVS, but the result was not statistically significant. Patients who had hydrocephalus with vascular causes (e.g. subarachnoid hemorrhage and intracranial hematoma) showed a significantly lower incidence of SVS than those with non-vascular causes (p=0.002).Conclusion: The incidence of SVS was higher in younger patients and in those with a non-vascular cause of hydrocephalus.
