Impact of healthcare disparities on the treatment and survival of patients with high-grade gliomas in Colombia: a multicenter inverse probability-weighted cohort analysis.

Purpose: Explore the impact of healthcare disparities in patients with high-grade glioma (HGG) in the Colombia's universal healthcare model setting, aiming to assess access to adjuvant treatment and survival outcomes among HGG patients covered under contributory versus subsidized insurance schemes in Bogotá, Colombia.

Methods: A retrospective cohort study was conducted in two academic neurosurgical centers in Bogotá, Colombia, each serving patient populations with a differential distribution by insurance scheme. Adult patients with newly diagnosed high-grade glioma (HGG) who underwent surgical management between 2017 and 2021 were included.

Local Control After Adjuvant Radiosurgery for Spinal Metastasis Treated With Decompression and Posterior Segmental Stabilization: A Comparison Between Carbon Fiber/Polyetheretherketone-Based and Metallic Implants.

Purpose: Carbon fiber-reinforced polyetheretherketone (CFRP) spinal implants are gaining popularity in the surgical management of spinal metastasis because of their physical and radiographic properties, which facilitate adjuvant radiation planning and tumor surveillance. Their impact on clinical outcomes is still under investigation. We evaluated the role of hardware material (CFRP vs titanium) in local control and hardware durability in metastatic cases receiving decompressive surgery and adjuvant spinal stereotactic radiosurgery (SSRS).

Generalizable model to predict new or progressing compression fractures in tumor-infiltrated thoracolumbar vertebrae in an all-comer population.

Objective: Neurosurgical evaluation is required in the setting of spinal metastases at high risk for leading to a vertebral body fracture. Both irradiated and nonirradiated vertebrae are affected. Understanding fracture risk is critical in determining management, including follow-up timing and prophylactic interventions.

Management of skull base meningiomas with extracranial extension: resection, recurrence, and prognostic factors.

Purpose: To assess clinical, radiographic, surgical, and pathological factors affecting outcomes in patients with skull-base meningiomas (SBMs) with extracranial extension, focusing on extent of resection (EOR), recurrence rates, postoperative complications, and skull-base (SB) reconstruction strategies.

Methods: We conducted a retrospective cohort study of 101 patients with SBMs and transcranial extension treated surgically between 1993 and 2024. Tumors were categorized by the Irish classification (Zones I-III).

Malignant mimic: pulmonary actinomycosis with contiguous vertebral involvement and spinal cord compression. Illustrative case.

Background: Actinomycosis is a rare, globally distributed disease with an annual incidence of 1 case per 300,000 persons. It classically manifests as a cervicofacial disease with sinus tract formation and purulent discharge with or without sulfur granules. Spinal compromise occurs in less than 5% of cases; however, it causes significant morbidity associated with neurological impairment.

Intraoperative ultrasound imaging features in high-grade metastatic spinal cord compression treated with separation surgery.

Objective: The aim of this study was to identify and characterize intraoperative ultrasound (iUS) findings during separation surgery for treatment of high-grade malignant epidural spinal cord compression that correlate with adequate decompression and prognostication of functional status.

Methods: A retrospective review identified 24 iUS images and videos obtained in 8 patients (age range 48-68 years) who underwent separation surgery for high-grade epidural compression. The following iUS parameters were assessed: the ventral and dorsal distances between the dura mater and spinal cord (i.

Functional and oncological outcomes after right hemisphere glioma resection in awake versus asleep patients: a systematic review and meta-analysis.

The right hemisphere has been underestimated by being considered as the non-dominant hemisphere. However, it is involved in many functions, including movement, language, cognition, and emotion. Therefore, because lesions on this side are usually not resected under awake mapping, there is a risk of unfavorable neurological outcomes.

The correlation of cerebral arteriovenous malformation flow measured by quantitative MR angiography on MR-detected arteriovenous malformation microhemorrhage.

Objective: The objective of this study was to assess the relationship of arteriovenous malformation (AVM) blood flow measured by quantitative MR angiography (QMRA) in nonruptured AVMs with MR-detected microhemorrhage.

Methods: All patients with unruptured AVMs who received baseline QMRA and gradient echo or susceptibility-weighted MRI were retrospectively reviewed (2004-2022). Imaging data, clinical history, and AVM angioarchitectural and flow features were collected and assessed.

Sphenoidal meningoencephalocele associated with CSF fistula and arteriovenous malformation Spetzler-Martin V: A case report.

Cerebral Arteriovenous malformations (AVMs) are presumed congenital anomalies of the blood vessels, which can increase intracranial pressure by uncertain mechanisms. We report the rare case of a 55-year-old male patient who complained about CSF rhinorrhea. Persisting CSF leakage prompted CT, which evidenced a bone defect in the right middle cranial fossa with protruding brain tissue.

Cerebrospinal fluid leak following penetrating trauma to the spine without neurological deficit: A case report.

Background: Posttraumatic spinal cerebrospinal fluid leak (CSFL) without neurological deficit is a rare entity. Historically, the first-line treatment is a nonsurgical approach, which includes Trendelenburg positioning, carbonic anhydrase inhibitor (acetazolamide), and subarachnoid catheter, with a high successful rate of leak correction. However, in some cases, this first-line treatment could fail, being necessary the surgical approach.

Focal, Extranodal Primary Polymorphous Hemangioendothelioma Treated With Endovascular Embolization and Resection Surgery.

A male 28-year-old patient complained of a dorsal mass that has been increasing in size in the last six months. The mass was painful, soft, no mobile, and no neurological symptoms or signs were documented. A vascular-type tumor was suspected and endovascular followed by open surgical resection was indicated.

Costotransversectomy plus hemilaminectomy as alternative surgical approach for extramedullary intradural thoracic schwannoma resection with and without extradural extension in pediatric population three cases and literature review.

Extramedullary intradural tumors constitute up to 25% of the spinal tumors. Commonly, schwannomas that presents with extradural and intradural compromise are called dumbbell-shaped tumor. The thoracic spine is a common localization for these tumors, especially in pediatric population.

A Colombian experience involving SpineJack, a consecutive series of patients experiencing spinal fractures, percutaneous approach and anatomical restoration 2016-2017.

Background: Spinal fractures are becoming more frequent and should be handled as a severe and endemic pathology that requires timely diagnosis and adequate treatment. The classification of the AOSpine is currently the classification used for this type of fractures, not only for its approach, but to predict surgical management.

Methods: These patients had spinal fracture reduction procedures done through percutaneous way with expander endovertebral implants, and intraosseous fixation using SpineJack intravertebral implants plus Cohesion cement.
