Discrepancies in Subjective Perceptions of Hydrocephalus Management and Self-Reported Outcomes.

: Despite surgical interventions with advances in endoscopic procedures as well as shunt technologies, the quality of life in patients with hydrocephalus can be poor. Clinical experience suggests discrepancies between objective measures of treatment success and subjective patient satisfaction. With this study, we retrospectively investigated patients' knowledge of their treatment as well as their satisfaction with received interventions.

Contralateral discectomy as a novel approach for disc herniation compressing a conjoined nerve root: illustrative case.

Background: A conjoined nerve root is a rare condition with numerous variants. The diagnosis can be challenging, especially when the condition coexists with other pathologies. In cases where a disc herniation affects these nerve roots, any miscalculation or inexperience of the surgeon can irreversibly injure them.

17 years of experience with shunt systems in normal pressure hydrocephalus - From differential pressure to gravitational valves.

Objective: Complication rate of shunting for normal pressure hydrocephalus (NPH) has significantly improved over the last decades. Especially the use of overdrainage protection has reduced the incidence of subdural hematoma and collections. However, gravitational valves were associated with other complications of shunt dysfunction.

Extradural lumbar arteriovenous fistula imitating a synovial cyst: illustrative case.

Background: Spinal dural arteriovenous fistula is the most common spinal vascular malformation. It usually presents with neurological deficits due to venous congestive myelopathy. Sometimes, however, the symptoms are radicular and can imitate those of a disc hernia or synovial cyst.

Interdisciplinary Therapeutic Approaches to Atypical and Malignant Meningiomas.

Meningiomas have the highest incidence among brain tumors. In contrast to benign tumors that constitute the majority of this tumor entity, the treatment of aggressive meningiomas (WHO Grade 2 and 3) is more challenging, requiring gross total removal of the tumor and the affected dura and adjuvant radiotherapy. Sometimes the location and/or the configuration of the tumor do not favor radical surgical resection without endangering the patient's clinical condition after surgery and pharmacological therapy has, until now, not been proven to be a reliable alternative.

Meningiomas with CNS invasion.

CNS invasion has been included as an independent criterion for the diagnosis of a high-grade (WHO and CNS grade 2 and 3) meningioma in the 2016 and more recently in the 2021 WHO classification. However, the prognostic role of brain invasion has recently been questioned. Also, surgical treatment for brain invasive meningiomas may pose specific challenges.

Design and Evaluation of a Custom-Made Electromyographic Biofeedback System for Facial Rehabilitation.

Background: In the rehabilitation of postoperative facial palsy, physical therapy is of paramount importance. However, in the early rehabilitation phase, voluntary movements are often limited, and thus, the motivation of patients is impacted. In these situations, biofeedback of facial electromyographic (EMG) signals enables the visual representation of the rehabilitation progress, even without apparent facial movements.

Interhemispheric differences in time-frequency representation of motor evoked potentials in brain tumor patients.

Objective: Conventional time-series parameters are unreliable descriptors of motor-evoked potentials (MEPs) in brain tumor patients. Frequency domain analysis is suggested to provide additional information about the status of the cortico-spinal motor system. Aim of the present study was to describe the time-frequency representation of MEPs and its relation to the motor performance.

Cortical and subcortical gray matter changes in patients with chronic tinnitus sustaining after vestibular schwannoma surgery.

Tinnitus is attributed to partial sensory deafferentation resulting in a central maladaptive neuroplasticity. Unfortunately, the agent of deafferentation is usually unknown or irreversible. In patients with unilateral vestibular schwannoma (VS), however, the auditory nerve is affected by a benign tumor.

Time-Frequency Representation of Motor Evoked Potentials in Brain Tumor Patients.

The integrity of the motor system can be examined by applying navigated transcranial magnetic stimulation (nTMS) to the cortex. The corresponding motor-evoked potentials (MEPs) in the target muscles are mirroring the status of the human motor system, far beyond corticospinal integrity. Commonly used time domain features of MEPs (e.

Herpes simplex meningitis after vestibular schwannoma surgery: illustrative case.

Background: Herpes is the most common cause of viral encephalitis in the young population. Herpes meningitis following brain surgery is very rare, however. Only a few cases are reported in the literature, and only one concerned an infection after vestibular schwannoma surgery.

Occurrence and management of postoperative pneumocephalus using the semi-sitting position in vestibular schwannoma surgery.

Background: The semi-sitting position in neurosurgical procedures is still under debate due to possible complications such as venous air embolism (VAE) or postoperative pneumocephalus (PP). Studies reporting a high frequency of the latter raise the question about the clinical relevance (i.e.

Neurophysiology-Driven Parameter Selection in nTMS-Based DTI Tractography: A Multidimensional Mathematical Model.

There is an increasing interest in preoperative diffusion tensor imaging-based fiber tracking (DTI-FT) to preserve function during surgeries in motor eloquent brain regions. However, DTI tractography is challenged by inherent presumptions during particular tracking steps [e.g.

Intracardial Catheter Migration of a Ventriculoperitoneal Shunt: Pathophysiology and Interdisciplinary Management.

Background: Intracardial migration of a ventriculoperitoneal (VP) shunt (ICMVP) is a rare complication that has been described in only single case reports. Here we report the successful interdisciplinary management of an ICMVP and provide a review of the relevant literature.

Case Description: A 38-year-old-patient with shunt-dependent hydrocephalus caused due to a Blake's pouch cyst presented in our hydrocephalus outpatient clinic with thoracic pain and nocturnal cough at 7 months after VP shunt implantation (with initially a proper location on computed tomography scan of the head and X-ray of the abdomen).

Postoperative Tinnitus After Vestibular Schwannoma Surgery Depends on Preoperative Tinnitus and Both Pre- and Postoperative Hearing Function.

Objective: Tinnitus is one of the most common symptoms before and/or after the surgical removal of a vestibular schwannoma (VS) affecting almost half of the patients. Although there is increasing evidence for the association of hearing impairment and VS-associated tinnitus, the effect of hearing deterioration due to surgery and its relation to the postoperative tinnitus (postTN) is poorly investigated. This knowledge, however, might (i) enlighten the pathophysiology of VS-associated tinnitus (i.

Movement symptoms in European Moyamoya angiopathy - First systematic questionnaire study.

Objective: Movement disorders are a rare manifestation of Moyamoya angiopathy (MMA). Data on prevalence and clinical presentation are warranted. Possible involuntary movements include focal motor seizures, tremor, limb-shaking transient ischemic attacks, choreiform and spastic or dystonic movement disorders.
