The first neurosurgical service in Texas: neurosurgery at the University of Texas Medical Branch (1937-2023).

The authors present a historical analysis of the first neurosurgical service in Texas. Initially established as a subdivision within the Department of Surgery in the early 1900s, this service eventually evolved into the Department of Neurosurgery at the University of Texas Medical Branch (UTMB). The pivotal contributions of individual chiefs of neurosurgery throughout the years are highlighted, emphasizing their roles in shaping the growth of the neurosurgery division.

COVID-19 and Stroke Recurrence by Subtypes: A Propensity-Score Matched Analyses of Stroke Subtypes in 44,994 Patients.

Background: Cerebrovascular diseases (CVDs), including varying strokes, can recur in patients upon coronavirus disease 2019 (COVID-19) diagnosis, but risk factor stratification based on stroke subtypes and outcomes is not well studied in large studies using propensity-score matching. We identified risk factors and stroke recurrence based on varying subtypes in patients with a prior CVD and COVID-19.

Methods: We analyzed data from 45 health care organizations and created cohorts based on ICDs for varying stroke subtypes utilizing the TriNetX Analytics Network.

Background: Middle meningeal artery embolization (MMAE) has been used as an effective minimally invasive treatment for chronic subdural hematoma (cSDH). The demographics and clinical outcomes after MMAE treatment for cSDH have not yet been studied using a national database.

Methods: We queried all MMAE cases up to October 7, 2020, from the TriNetX Analytics Network.

L5 Fracture Dislocation Secondary to Cold Abscess Treated by Posterior Corpectomy With Expandable Cage Placement.

Infections of the lumbar spine can have serious sequelae, including neurological deficits, paralysis, and death. Prolonged infection can result in fracture of the vertebrae, local abscesses, and infiltration and compression of local vascular structures. In cases with significant instability or neurological compromise, a common treatment approach is vertebral corpectomy with interbody cage followed by long-term antibiotics.

How the elderly fare after brain tumor surgery compared to younger patients within a 30-day follow-up: A National surgical Quality Improvement Program analysis of 30,183 cases.

The growing elderly population in Western societies has led to an increasing number of primary brain tumors occurring in patients beyond the age of 65. The purpose of this study was to assess and compare the safety, efficacy, and outcomes of oncological craniotomy procedures between patients above and below 65 years. We performed a retrospective analysis of the ACS-NSQIP database to identify patients undergoing supratentorial and infratentorial tumor excisions by neurosurgeons between 2008 and 2016.

A Systematic Review of Ion Radiotherapy in Maintaining Local Control Regarding Atypical and Anaplastic Meningiomas.

Objective: Atypical and anaplastic meningiomas, unlike their benign counterparts, are highly aggressive, locally destructive, and likely to recur after treatment. These diseases are difficult to definitively treat with traditional radiotherapy without injuring adjacent brain parenchyma. The physical properties of ion radiotherapy allows for treatment plans that avoid damaging critical neural structures.

Effect of an additional neurosurgical resident on procedure length, operating room time, estimated blood loss, and post-operative length-of-stay.

Neurosurgical residency training is costly, with expenses largely borne by the academic institutions that train residents. One expense is increased operative duration, which leads to poorer patient outcomes. Although other studies have assessed the effect of one resident assisting, none have investigated two residents; thus, we sought to investigate if two residents versus one scrubbed-in impacted operative time, estimated blood loss (EBL), and length-of-stay (LOS).

Cefazolin versus vancomycin for neurosurgical operative prophylaxis - A single institution retrospective cohort study.

Objectives: Cefazolin and vancomycin are common choices for neurosurgical antimicrobial prophylaxis. Cefazolin is typically first-line due to its lower toxicity profile and specificity for gram-positives such as skin commensals, while vancomycin is often reserved for patients with cephalosporin or penicillin allergies. However, one randomized clinical trial demonstrated superiority of vancomycin for cerebrospinal fluid (CSF) shunt insertions at a hospital with a high prevalence of methicillin-resistance Staphylococcus aureus (MRSA).

Metabolic Syndrome Associated with Increased Rates of Medical Complications After Intracranial Tumor Resection.

Background: When diagnosed simultaneously, obesity, diabetes, and hypertension form a medical constellation called metabolic syndrome (MetS). The prevalence of MetS in Western cultures has been on a steady increase and MetS has been associated with increased postoperative complications in multiple surgical settings.

Objective: In this study, we evaluate the relationship between MetS and the outcomes of craniotomy for supratentorial brain tumor.

Machine learning applications for the differentiation of primary central nervous system lymphoma from glioblastoma on imaging: a systematic review and meta-analysis.

OBJECTIVEGlioblastoma (GBM) and primary central nervous system lymphoma (PCNSL) are common intracranial pathologies encountered by neurosurgeons. They often may have similar radiological findings, making diagnosis difficult without surgical biopsy; however, management is quite different between these two entities. Recently, predictive analytics, including machine learning (ML), have garnered attention for their potential to aid in the diagnostic assessment of a variety of pathologies.

Pseudarthrosis due to galvanic corrosion presenting as subarachnoid hemorrhage.

Two unlike metals near one another can break down as they move toward electrochemical equilibrium resulting in galvanic corrosion. We describe a case of electrochemical corrosion resulting in pseudarthrosis, followed by instrumentation failure leading to subarachnoid hemorrhage. A 53-year-old female with a history of cervical instability and two separate prior cervical fusion surgery with sublaminar cables presented with new onset severe neck pain.

Low-Dose Gamma Knife Radiosurgery for Vestibular Schwannomas: Tumor Control and Cranial Nerve Function Preservation After 11 Gy.

Objectives: This study aims to report tumor control rates and cranial nerve function after low dose (11.0 Gy) Gamma knife radiosurgery (GKRS) in patients with vestibular schwannomas.

Methods: A retrospective chart review was performed on 30 consecutive patients with vestibular schwannomas treated from March 2004 to August 2010 with GKRS at the Robert H.

Comparing Radiation Dose from Conventional Fluoroscopy to Intraoperative Cone Beam CT (O-arm) during Percutaneous Lesioning Procedures of the Gasserian Ganglion.

Introduction: The use of intraoperative CT-guidance during the percutaneous treatment of trigeminal neuralgia has become increasingly popular due to the greater ease of foramen ovale cannulation and decreased procedure times. Concerns regarding radiation dose to the patient, however, remain unaddressed. We sought to compare the emitted radiation dose from fluoroscopy with intraoperative CT for these procedures.

Spontaneous Thrombosis and Subsequent Recanalization of a Developmental Venous Anomaly.

Developmental venous anomalies (DVA) are among the most common congenital malformations of the cerebral angioarchitecture. Spontaneous thrombosis of this entity is rare, and our review of the literature found only 31 reported cases of symptomatic spontaneous thrombosis of developmental venous anomalies. Here, we report a unique case describing the spontaneous thrombosis of a DVA leading to venous infarction and subsequent recanalization.

Comparison of open and minimally invasive surgery for intradural-extramedullary spine tumors.

OBJECT Patients with symptomatic intradural-extramedullary (ID-EM) tumors may be successfully treated with resection of the lesion and decompression of associated neural structures. Studies of patients undergoing open resection of these tumors have reported high rates of gross-total resection (GTR) with minimal long-term neurological deficit. Case reports and small case series have suggested that these patients may be successfully treated with minimally invasive surgery (MIS).

Development of venous thromboembolism (VTE) in patients undergoing surgery for brain tumors: results from a single center over a 10 year period.

Patients who undergo craniotomy for brain neoplasms have a high risk of developing venous thromboembolism (VTE), including deep vein thromboses (DVT) and pulmonary emboli (PE). The reasons for this correlation are not fully understood. This retrospective, single-center review aimed to determine the risk factors for VTE in patients who underwent neurosurgical resection of brain tumors at Northwestern University from 1999 to 2010.

Evidence-based management of deep wound infection after spinal instrumentation.

In this study, evidence-based medicine is used to assess optimal surgical and medical management of patients with post-operative deep wound infection following spinal instrumentation. A computerized literature search of the PubMed database was performed. Twenty pertinent studies were identified.

Thoracic spinal cord intramedullary aspergillus invasion and abscess.

Invasive central nervous system aspergillosis is a rare form of fungal infection that presents most commonly in immunocompromised individuals. There have been multiple previous reports of aspergillus vertebral osteomyelitis and spinal epidural aspergillus abscess; however to our knowledge there are no reports of intramedullary aspergillus infection. We present a 19-year-old woman with active acute lymphoblastic leukemia who presented with several weeks of fevers and bilateral lower extremity weakness.

Venous thromboembolism in high grade glioma among surgical patients: results from a single center over a 10 year period.

Patients with high-grade glioma are at elevated risk of venous thromboembolism (VTE). The relationship between VTE and survival in glioma patients remains unclear, as does the optimal protocol for chemoprophylaxis. The purpose of this study was to assessthe incidence of and risk factors associated with VTE in patients with high-grade glioma, and the correlation between VTE and survival in this population.

Survival after surgery and stereotactic radiosurgery for patients with multiple intracranial metastases: results of a single-center retrospective study.

Objectives: Patients with systemic cancer and a single brain metastasis who undergo treatment with resection plus radiotherapy live longer and have a better quality of life than those treated with radiotherapy alone. Historically, whole-brain radiotherapy (WBRT) has been the mainstay of radiation therapy; however, it is associated with significant delayed neurocognitive sequelae. In this study, the authors looked at survival in patients with single and multiple intracranial metastases who had undergone surgery and adjuvant stereotactic radiosurgery (SRS) to the tumor bed and synchronous lesions.

Delayed malignant transformation of petroclival meningioma to chondrosarcoma after stereotactic radiosurgery.

Stereotactic radiosurgery (SRS) is often used as adjuvant treatment for residual or recurrent tumor following microsurgical resection of posterior fossa meningiomas. SRS is associated with excellent rates of local control, however long-term complications remain unclear. Secondary malignancy is an often discussed but rarely described complication of SRS.

Acute branch occlusion after Pipeline embolization of intracranial aneurysms.

Flow-diverters are used in the treatment of large and complex intracranial aneurysms. One major concern with this concept is the potential for compromise of side branches and perforators covered by the device. We describe three patients treated with the Pipeline embolization device (PED; ev3 Endovascular, Plymouth, MN, USA) who developed immediate compromise of flow into an eloquent side branch covered by the device.
