Complications and outcomes of carotid artery stenting in high-risk cases.

Objectives: Carotid artery stenting is sometimes adapted for some at-risk cases; however, appropriate treatment timing with stroke onset is controversial. This study aims to identify factors that have an impact on complications and outcomes, especially in patients at high risk.

Materials And Methods: We examined the characteristics of 152 consecutive patients treated by carotid artery stenting between January 2018 and March 2022 and retrospectively analyzed the risk factors for complications and poor outcomes (modified-Rankin-Scale deterioration), such as patient background, carotid artery stenting risks (access route tortuosity, severe calcification, vulnerable plaque, estimated glomerular filtration rate <30 mL/min/1.

Ischemic Cerebellar Stroke in a Young Patient With Neurofibromatosis Type 2: A Case Report.

Background: Neurofibromatosis type 2 (NF2) is a multifaceted disease characterized primarily by benign CNS tumors, especially meningiomas and vestibular schwannomas. There have been several cases of brainstem ischemic stroke in young NF2 patients reported in the literature. To date, there is no unified theory about the connection between NF2 and pediatric stroke.

Artificial Intelligence in Neurosurgery: A State-of-the-Art Review from Past to Future.

In recent years, there has been a significant surge in discussions surrounding artificial intelligence (AI), along with a corresponding increase in its practical applications in various facets of everyday life, including the medical industry. Notably, even in the highly specialized realm of neurosurgery, AI has been utilized for differential diagnosis, pre-operative evaluation, and improving surgical precision. Many of these applications have begun to mitigate risks of intraoperative and postoperative complications and post-operative care.

Complex regional pain syndrome.

Complex regional pain syndrome (CRPS), formerly called reflex sympathetic dystrophy (RSD), is a chronic pain phenomenon associated with an alteration in peripheral and central pain perception in a localized body region. Because of the many risk factors associated with this phenomenon, the true nature of the disease risk and clinical course are a challenge to predict. After the diagnosis is confirmed and treatment is provided promptly, clinicians must consider patient health and function holistically to foster improvement in overall quality of life.

Vitamin D status and latitude predict brain lesions in adrenoleukodystrophy.

Objectives: Approximately 40% of boys with X-linked adrenoleukodystrophy (ALD) develop inflammatory demyelinating brain lesions (cerebral ALD, cALD) and are at risk for death or severe disability. Risk factors for cALD are poorly understood. Our objective was to evaluate whether vitamin D status, which influences immune function, is associated with risk for cALD.

Frontotemporal Craniotomy for Clipping of Unruptured Aneurysm Using a Diamond-Coated Thread Wire Saw and Reconstruction Using Calcium Phosphate Cement without Metal Fixation.

Metal fixation systems for cranial bone flaps cut by a drill are convenient devices for cranioplasty, but cause several complications. We use modified craniotomy using a fine diamond-coated threadwire saw (diamond T-saw) to reduce the bone defect, and osteoplasty calcium phosphate cement without metal fixation. We report our outcomes and tips of this method.

Maximum Safety Limits of Laminectomy of the C1 Vertebra for Chiari Malformation Surgery: A Finite Element Analysis.

Background: The treatment of Chiari malformations generally consists of posterior fossa decompression. C1 laminectomy is required in selected cases. However, cases of iatrogenic anterior arch fractures at C1 without high-energy trauma have been reported.

Technique of Distraction, Compression, Extension, Reduction to Reduce and Realign Old Displaced Odontoid Fracture From Posterior Approach: A Novel Technique.

Objective: Chronic 'displaced' displaced type II fractures, though uncommon, are difficult to manage. They usually require a transoral procedure followed by a posterior instrumented fusion. We describe here, a new method to reduce the fractured displaced odontoid using a posterior cervical approach only.

Reduced likelihood of the Poggendorff illusion in cerebellar strokes: a clinical and neuroimaging study.

This study aimed to test our hypothesis that the cerebellum plays an important role in the generation of the optical-geometric illusion known as the Poggendorff illusion, the mechanism of which has been explained by accumulated experience with natural scene geometry. A total of 79 participants, comprising 28 patients with isolated cerebellar stroke, 27 patients with isolated cerebral stroke and 24 healthy controls, performed Poggendorff illusion tasks and 2 different control tasks. We also investigated core brain regions underpinning changes in the experience of the illusion effect using multivariate lesion-symptom mapping.

Spinal Schwannomas: A Proposal for a New Classification to Aid Surgical Planning.

Background The treatment of spinal schwannomas, which is the most common nerve sheath tumor, is total microsurgical resection. The localization, size and relationship with the surrounding structures of these tumors are crucial in terms of preoperative planning. A new classification method is presented in this study for the surgical planning of spinal schwannoma.

Minimally invasive tubular approach for lumbar extraforaminal disc herniation: how I do it.

Background: Minimally invasive surgical resection of extraforaminal disc herniation is challenging. The anatomical landmarks are varying from common interlaminar approach. The main risk is to damage the exiting nerve root as it is not yet protected by any bony structure.

The Efficacy of Blended Learning in a Pediatric Spine Deformity Management Program in Sub-Saharan Africa.

Introduction: Our study assessed the efficacy of blended learning, which combines in-person learning and e-learning, in a pediatric scoliosis training program through an international collaborative effort.

Methods: The course comprised two parts: the online portion, where participants reviewed educational materials for 3 weeks and met with faculty once/week for discussion, and the in-person session, where participants reviewed cases in a team-based approach and came to a consensus on treatment strategy, followed by discussion with an international expert. All participants completed a needs assessment (NA) and clinical quiz at three points: before the course, after the online session, and after the in-person session, which covered various topics in pediatric spine deformity.

Effectiveness of active occupational therapy in patients with acute stroke: A propensity score-weighted retrospective study.

Background And Purpose: The effects of therapy and patient characteristics on rehabilitation outcomes in patients with acute stroke are unclear. We investigated the effects of intensive occupational therapy (OT) on patients with acute stroke.

Methods: We performed a retrospective cohort study using the 2005-2016 Japan Rehabilitation Database, from which we identified patients with stroke ( = 10,270) who were admitted to acute care hospitals ( = 37).

Cerebral foreign body granulomas after mechanical thrombectomy: Two case reports and a review of the literature.

Objectives: A foreign body granuloma after an endovascular intervention is a rare complication. Some cases of foreign body granulomas, especially after coil embolization, have been reported. However, only four cases of foreign body granulomas after mechanical thrombectomy (MT) have previously been reported.

Decompression alone versus decompression with fusion in patients with lumbar spinal stenosis with degenerative spondylolisthesis: a systematic review and meta-analysis.

Introduction: Surgical decompression is standard care in the treatment of degenerative spondylolisthesis in patients with symptomatic lumbar spinal stenosis, but there remains controversy over the benefits of adding fusion. The persistent lack of consensus on this matter and the availability of new data warrants a contemporary systematic review and meta-analysis of the literature.

Methods: Multiple online databases were systematically searched up to October 2022 for randomized controlled trials (RCTs) and prospective studies comparing outcomes of decompression alone versus decompression with fusion for lumbar spinal stenosis in patients with degenerative spondylolisthesis.

Short-Term Results of Simpson Grade 2 Resection in Spinal Meningiomas.

Background: Spinal meningiomas are benign and slow-growing intradural tumors. Surgery is the choice of treatment. In this retrospective study, results of minimally invasive Simpson grade 2 resection and its impact on recurrence in 44 spinal meningiomas are reviewed.

Visual suppression of vestibulo-ocular reflex in patients treated with carotid artery revascularization: A potential biomarker for cerebral perfusion.

Background: Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are common treatments for ischemic stroke prevention in patients with carotid artery stenosis. However, the beneficial effects of CEA/CAS for cerebral hypoperfusion due to carotid artery stenosis have yet to be fully established. As dizziness is a common symptom in patients with carotid artery stenosis, we aimed to evaluate the effects of CEA/CAS on cerebral function in patients with carotid artery stenosis, using equilibrium function tests.
