Current Indications, Trends, and Long-Term Results of 233 Bypasses to Treat Complex Intracranial Aneurysms: A Location-Specific Analysis.

Background And Objectives: Advances in endovascular flow diverters have led to a secular shift in the management of brain aneurysms, causing debate on current bypass indications. We therefore sought to investigate the long-term results, current indications, and trends of bypasses for brain aneurysms.

Methods: We retrospectively reviewed bypasses performed between 2005 and 2022 to treat brain aneurysms.

Functional and Radiographic Outcomes of Cavernous Meningiomas Based on Treatment Modality.

 Cavernous sinus meningiomas (CSMs) are challenging given their proximity to neurovascular structures. Treatments include surgery, radiation, or observation. There are little data comparing outcomes based on treatment.

High-Flow Bypass and Clip Trapping of a Giant Fusiform Middle Cerebral Artery (M1) Aneurysm: Technical Case Instruction.

Background And Importance: Giant intracranial aneurysms have a poor natural history with mortality rates of 68% and 80% over 2-year and 5-year, respectively. Cerebral revascularization can provide flow preservation while treating complex aneurysms requiring parent artery sacrifice. In this report, we describe the microsurgical clip trapping and high-flow bypass revascularization for a giant middle cerebral artery (MCA) aneurysm.

Comparison of Surgical Outcomes and Recurrence Rates of Cystic and Solid Vestibular Schwannomas.

 Cystic vestibular schwannomas (CVSs) are anecdotally believed to have worse clinical and tumor-control outcomes than solid vestibular schwannomas (SVSs); however, no data have been reported to support this belief. In this study, we characterize the clinical outcomes of patients with CVSs versus those with SVSs.  This is a retrospective review of prospectively collected data.

The Medical College of Wisconsin Department of Neurosurgery delivers subspecialty adult and pediatric neurosurgical care that is patient-centered, evidence-informed, and value-based. Medical College of Wisconsin research advances the science of neurological disease with the goal of a positive translational effect on clinical care. The department supports an environment of education and scholarship for trainees, faculty, and staff alike.

Safe Use of Tissue Plasminogen Activator in Conjunction with the Integra Camino Bolt for the Drainage of Chronic Subdural Hematoma.

Chronic subdural hematoma (CSDH) is a relatively common condition encountered in a neurosurgical practice. There have been increased efforts in creating different treatment regimens for CSDH to improve patients' outcomes, including the addition of tissue plasminogen activator (tPA) in drains to reduce recurrences. Here, we present the first case report of the safe use of tPA in conjunction with an Integra Camino bolt for maximized drainage of CSDH with a successful neurological recovery and the complete resolution of the hematoma.

A Rare Extra-Axial Midline Tentorial Adult Medulloblastoma with Dural-Tail Sign Mimicking a Meningioma.

Medulloblastomas are categorized as the World Health Organization Grade IV neoplasms. Only 33 cases have been reported of extra-axial, mostly in the cerebellar pontine angle and lateral cerebellar hemisphere, medulloblastomas in the current literature. Our study showcases the first case of an extremely rare presentation of an extra-axial midline tentorial adult medulloblastoma with the dural-tail sign mimicking a meningioma.

A Novel Application of the Integra Camino Bolt for the Drainage of Chronic Subdural Hematoma: A Technical Note.

Chronic subdural hematoma (cSDH) is a common neurosurgical pathology associated with older age and complicated by antiplatelet/anticoagulant therapies. With improving medical care in an aging population, the incidence of cSDH will likely increase over the next 25 years, placing a burden on health care costs. Consequently, a simple and inexpensive treatment option is desirable.

Acid ceramidase is a novel drug target for pediatric brain tumors.

Pediatric brain tumors are the most common solid tumors in children and are also a leading culprit of cancer-related fatalities in children. Pediatric brain tumors remain hard to treat. In this study, we demonstrated that medulloblastoma, pediatric glioblastoma, and atypical teratoid rhabdoid tumors express significant levels of acid ceramidase, where levels are highest in the radioresistant tumors, suggesting that acid ceramidase may confer radioresistance.

A rare remarkable recovery in a pediatric patient with the bi-hemispheric, transventricular trajectory craniocerebral gunshot wound.

The gunshot wound to the head (GSWH) is associated with a mortality rate of 20-90% in adults and 20-65% in the pediatric population. Due to the high rates of mortality and morbidity, the management of these patients has been a topic of high interest in the neurosurgical community. We present an 18-year-old male suffering a GSWH with the bullet following a transventricular trajectory and crossing the midsagittal plane, creating extensive intracranial injuries.

A 5-Year Retrospective Analysis of Exposure to Ionizing Radiation by Neurosurgery Residents in the Modern Era.

Background: The potential for radiation exposure during neurosurgical training has increased dramatically in the last decade. Incorporation of instrumented and minimally invasive spinal surgery and neuroendovascular procedures into the curriculum has led to increased potential for exposure to ionizing radiation. Contemporary neurosurgery residents' exposure to radiation has not been previously reported.

Radiation Necrosis Secondary to Trigeminal Nerve TomoTherapy: A Cautionary Case Study.

New radiation delivery modalities have recently challenged Gamma Knife surgery as the historic gold standard in the treatment of trigeminal neuralgia (TN). TomoTherapy, a relative newcomer, has been approved by the U.S.

Surgical and clinical efficacy of sacroiliac joint fusion: a systematic review of the literature.

Object: The sacroiliac joint (SIJ) and surgical intervention for treating SIJ pain or dysfunction has been a topic of much debate in recent years. There has been a resurgence in the implication of this joint as the pain generator for many patients experiencing low-back pain, and new surgical methods are gaining popularity within both the orthopedic and neurosurgical fields. There is no universally accepted gold standard for diagnosing or surgically treating SIJ pain.

Long-term functional outcomes and predictors of shunt-dependent hydrocephalus after treatment of ruptured intracranial aneurysms in the BRAT trial: revisiting the clip vs coil debate.

Background: Acute hydrocephalus is a well-known sequela of aneurysmal subarachnoid hemorrhage (SAH). Controversy exists about whether open microsurgical methods serve to reduce shunt dependency compared with endovascular techniques.

Objective: To determine predictors of shunt-dependent hydrocephalus and functional outcomes after aneurysmal SAH.
