5-ALA enhanced fluorescence guided microscopic to endoscopic (M2E) resection of deep frontal subcortical GBM.
Glioblastoma multiforme remains the most common adult primary brain tumor with a life expectancy of 15-18 months following best treatment strategies. Current paradigms incorporate maximal safe resection, chemotherapy, and radiation.1 Multiple variables correlate with increased survival; perhaps most notably are stepwise survival advantages following 78% and 98% extent of resection thresholds.2,3 5-Aminolevulinic acid has become a vital tool in the intraoperative identification and differentiation of high-grade glioma as it provides a fluorescent effect capable of distinguishing tumor from normal brain tissue when observed under blue light, which to date has been used primarily via a microscopic light source.4 However, this effect is attenuated with increasing distance between the blue light source and the tumor, as in the case of deep seated resection cavities.5 We aimed to overcome this obstacle by using a blue light endoscope as the primary visualization platform, thereby advancing the light source directly into the resection cavity. We present the case of a 69-year-old man with a deep left frontal subcortical lesion proven to be glioblastoma multiforme on prior biopsy. ⋯ Tumor resection proceeded under direct blue light endoscopy with intermittent subcortical motor mapping until a threshold of 4 mA was reached. The patient had transient right arm and leg weakness. Postoperative magnetic resonance imaging confirmed >98% resection (Video 1).

Documentation is the cornerstone of good patient care and vital to proper coding and billing. Consistent and standardized documentation improves communication among physicians and can lead to better reimbursement. By understanding which elements in the neurosurgery history and physical examination are omitted the most often and the effects on the coding level, institutional-specific solutions can be implemented. ⋯ The most common missing elements for inpatient neurosurgery documentation were the review of systems and physical examination. The documents with the highest percentage of missing elements were those that used dynamic documentation without a template. We recommend implementing a dedicated NHPT to improve capturing these elements for improved clinical documentation. Such changes could also improve the coding level and subsequent reimbursement.

Because of involvement of the optic apparatus, craniopharyngiomas frequently present with visual deterioration. Although visual improvement is a primary goal of surgical intervention, prediction models are lacking. ⋯ Patients with reduced preoperative vision, specific radiographic vascular involvement, and gross total resection showed increased odds of visual improvement, whereas the translaminar approach was associated with visual deterioration. Such characteristics may facilitate patient-surgeon counseling and surgical decision making.

Despite evidence to support that aneurysmal subarachnoid hemorrhage (aSAH) is best treated at high-volume centers, it is unknown whether clinical practice reflects these findings. ⋯ Between 2006 and 2017, transfers to our center for aSAH declined. However, transferred patients had greater levels of complexity, more comorbidities, and were at greater risk for vasospasm based on their presenting Fisher score. Nonetheless, average LOS, in-hospital mortality, and cost declined. These changing referral patterns have implications for outcome data, quality reporting, resident education, and developing systems of care to optimize outcomes.

Spinal hemangiomas are common primary tumors of the vertebrae. Although these tumors are most frequently benign and asymptomatic, they can rarely exhibit aggressive growth and invasion into neighboring structures. Treatment for these aggressive variants is controversial, often involving surgery, chemotherapy, and/or radiotherapy. This study sought to investigate current trends affecting overall survival (OS) using the National Cancer Database (NCDB) and to formulate treatment recommendations. ⋯ This retrospective analysis finding that treatment with surgical resection and/or radiotherapy is associated with increased OS constitutes the largest cohort of patients with aggressive vertebral hemangiomas to date. Given that the mean OS of the study cohort was 1.94 years, our findings suggest that the optimal treatment regimen to maximize survival should consist of early surgical resection with adjuvant high-dose radiotherapy.
