Surgical technique: Posterior retropleural thoracotomy for resection of a T10 dumbbell schwannoma.

Background: Myelopathy and nerve root dysfunction resulting from the imperceptible growth of intraspinal schwannomas have been well documented.[1] Thoracic spine schwannomas, in particular, have exceptional growth potential due to the presence of the posterior mediastinum and retropleural spaces accommodating insidious and often subclinical tumor expansion.[5] Extraspinal extension of these lesions, however, poses a distinct challenge for surgeons.

Technical nuances for the resection of cervical dumbbell schwannomas.

The majority of spinal nerve sheath tumors are within the intradural/extramedullary compartment. A subset of these tumors develop extraforaminal components that gradually expand into potential spaces. Herein, the authors provide a 2D video demonstrating the technical nuances concerning resection of cervical dumbbell schwannomas with extraspinal extension.

Effect of Race and Insurance Type on Access to, and Outcomes of, Epilepsy Surgery: A Literature Review.

Background: Despite higher rates of seizure freedom, a large proportion of patients with medically refractory seizures who could benefit from epilepsy surgery do not receive surgical treatment. This literature review describes the association of race and insurance status with epilepsy surgery access and outcomes.

Methods: Searches in Scopus and PubMed databases related to disparities in epilepsy surgery were conducted.

Illustrative resection of mixed intra- and extramedullary thoracic spinal cord capillary hemangioma.

Background: Capillary hemangiomas are typically superficial benign tumors of the cutaneous and mucosal tissues of the face and neck in pediatric patients. In adults, they typically occur in middle-aged males who present with pain, myelopathy, radiculopathy, paresthesias, and bowel/bladder dysfunction. The optimal treatment for intramedullary spinal cord capillary hemangiomas is gross total/ resection.

Applications of Carbon Fiber Instrumentation in Spinal Oncology: Recent Innovations in Spinal Instrumentation and 2-Dimensional Illustrative Operative Video.

Background: The management of spinal oncology necessitates a multimodal approach, with surgical intervention, radiation-based therapy, and postoperative advanced imaging. These systems must work well together to provide optimal patient outcomes. Traditional metallic spinal implants produce image artifacts and lead to radiation dose attenuation, which inhibit both disease monitoring and disease treatment, respectively.

Operative Technique for Resection of a Ventral Transdural Retro-Odontoid Pannus: A 2-Dimensional Operative Video.

Background: Retro-odontoid pseudotumors are rare inflammatory complications of atlantoaxial instability often associated with cervical degenerative disease and rheumatoid arthritis. While propagation of these lesions has been shown to cause spinal cord compression and cervical myelopathy, intradural extension has rarely been reported.

Methods: In this manuscript and 2-dimensional illustrative intraoperative video, we demonstrate cervical decompression, removal of the intradural component, and stabilization with C1-2 instrumentation using a posterior approach.

Intraspinal pilocytic astrocytomas: An overview and 2-D illustrative resection technique video.

Background: Spinal cord pilocytic astrocytomas (PAs) are rare and typically occur in pediatric patients. While PAs are often well-circumscribed and amenable to gross total resection, they sometimes harbor infiltrative components that can invade normal cord parenchyma.

Methods: Here, we present a 59-year-old female with a progressive right-sided hemi-sensory loss, right-sided hemiparesis, and gait imbalance.

Can responsive deep brain stimulation be a cost-effective treatment for severe obesity?

Objective: A first-in-human responsive deep brain stimulation (rDBS) trial (NCT03868670) for obesity is under way, which is based on promising preclinical evidence. Given the upfront costs of rDBS, it is prudent to examine the success threshold for cost-effectiveness compared with laparoscopic Roux-en-Y gastric bypass (LRYGB).

Methods: Efficacy and safety data on LRYGB and safety data on rDBS were collected for established indications through a literature search.

Bullet retrieval from the cauda equina after penetrating spinal injury: A case report and review of the literature.

Background: When gunshot injuries occur to the spine, bullet fragments may be retained within the spinal canal. Indications for bullet removal include incomplete spinal cord injury, progressive loss of neurologic function including injury to the cauda equina, and dural leaks with impending risk of meningitis.

Case Description: Here, we present a 34-year-old male with a missile penetrating spinal injury to the cauda equina.

History of Women in Neurosurgery (WINS).

In 2020, the Women in Neurosurgery (WINS) organization, a joint section of the AANS and Congress of Neurological Surgeons, celebrated 30 years since its inception. In this paper, the authors explore the history of WINS from its beginnings through its evolution over the past three decades. The achievements of the group are highlighted, as well as the broader achievements of the women in the neurosurgical community over this time period.

Bilateral Deep Brain Stimulation is the Procedure to Beat for Advanced Parkinson Disease: A Meta-Analytic, Cost-Effective Threshold Analysis for Focused Ultrasound.

Background: Parkinson disease (PD) impairs daily functioning for an increasing number of patients and has a growing national economic burden. Deep brain stimulation (DBS) may be the most broadly accepted procedural intervention for PD, but cost-effectiveness has not been established. Moreover, magnetic resonance image-guided focused ultrasound (FUS) is an emerging incisionless, ablative treatment that could potentially be safer and even more cost-effective.

Contemporaneous evaluation of patient experience, surgical strategy, and seizure outcomes in patients undergoing stereoelectroencephalography or subdural electrode monitoring.

Objective: Intracranial electrographic localization of the seizure onset zone (SOZ) can guide surgical approaches for medically refractory epilepsy patients, especially when the presurgical workup is discordant or functional cortical mapping is required. Minimally invasive stereotactic placement of depth electrodes, stereoelectroencephalography (SEEG), has garnered increasing use, but limited data exist to evaluate its postoperative outcomes in the context of the contemporaneous availability of both SEEG and subdural electrode (SDE) monitoring. We aimed to assess the patient experience, surgical intervention, and seizure outcomes associated with these two epileptic focus mapping techniques during a period of rapid adoption of neuromodulatory and ablative epilepsy treatments.
