Review Case Reports
Chronic epidural hematoma caused by traumatic intracranial pseudoaneurysm of the middle meningeal artery: review of the literature with a focus on this unique entity.
Pseudoaneurysms of the middle meningeal artery represent fewer than 1% of all intracranial aneurysms; it can be associated with different patterns of intracranial hemorrhages. A chronic epidural hematoma (CEDH) caused by post-traumatic pseudoaneurysm of the middle meningeal artery (MMA) has not yet been reported. ⋯ Pseudoaneurysms are considered unstable because of the poor support of the aneurysmal wall. They tend to progressively increase in size and ultimately rupture, leading to delayed intracranial bleeding. A univocal definition of the interval of time between the acute head trauma and the diagnosis to classify the CEDH is still debated. To our knowledge, this is the first case described of a CEDH secondary to a pseudoaneurysm of the MMA. In our study we suggest defining CEDHs as extradural hematomas diagnosed and/or treated 21 days or more after a head injury.

Review Meta Analysis
Use of Focused Ultrasound (Sonication) for the Diagnosis of Infections in Neurosurgical Operations: a Systematic Review and Meta-Analysis.
Postoperative infections are one of the most devastating complications in neurosurgery, and their results are even more disastrous when biocompatible implants are involved. As the application of these implants increases, the need for a sensitive and efficient method to detect pathogens becomes imperative. The application of sonication appears to be a viable option. ⋯ Regardless of the potential of sonication, it is still not a panacea. Additional studies are expected to provide significant insight into the indications and limitations of this technique.

Outcome prediction in severe traumatic brain injury (sTBI) has been studied using clinical and radiographic measurements and by using biomarkers such as glial fibrillary acidic protein, ubiquitin C-terminal hydrolase-L1, and tau. Routine blood tests are regularly performed in patients with sTBI and could be used to predict outcomes. This study aims to investigate whether routine blood tests on admission can be predictive of outcome in patients with sTBI. ⋯ No routine blood tests measured on admission were significant predictors of outcome in patients with sTBI. Other clinical and radiologic factors may be better suited to predicting outcomes in this patient population.

Although Thrombolysis in Cerebral Infarction (TICI) grade 2B or 3 is considered successful after endovascular thrombectomy (EVT) for acute ischemic stroke, TICI 2B was found to be associated with poorer outcomes than was 3. Furthermore, the newly proposed TICI 2C grade seems to be clinically equivalent to TICI 3 rather than to 2B. This network meta-analysis aimed to assess the differences in clinical outcomes between TICI grades and redefine successful reperfusion. ⋯ Patients with TICI 2C grade would be distinguished from those with 2B, because 2C is clinically equivalent to 3 and has a better outcome than 2B. Therefore, achieving 2C or 3 is likely to be closer to the successful aim of endovascular thrombectomy in acute ischemic stroke than achieving 2B.

Chiari malformation (CM) is often comorbid with syringomyelia. The treatment of CM via posterior fossa decompression (PFD) may not improve syringomyelia in up to 40% of patients, based on historical cohorts. Management of these patients is problematic, as both reoperation and syrinx shunting have high failure rates in the long term. ⋯ In this small cohort of unique patients, syrinx resolution was not achieved via decompression surgery. Despite "radiographic failure," good symptom control was achieved, with most patients remaining or becoming asymptomatic postoperatively, thus supporting our rationale for what has largely been a conservative approach in this population.
