Review Meta Analysis
The Role of Pre-operative Embolization in Carotid Body Tumor Surgery: a Systematic Review and Meta-analysis.
Carotid body tumors (CBTs) are highly vascularized tumors which can render tumor resection surgery challenging. There is evidence suggesting that preoperative selective embolization can reduce blood loss during surgery and decrease the risk of perioperative complications; however, recent reports have questioned the benefits that preoperative embolization provides. The objective of this study is to investigate the impact of preoperative embolization on CBT surgical resection. ⋯ Patients who received embolization prior to CBT resection had statistically significant lower blood loss and shorter duration of operation. The rates of CN palsy, stroke, TIA, and length of stay were similar between patients who had preoperative embolization and those who did not.

Review Multicenter Study
Decompressive craniectomy in children with severe traumatic brain injury: a multicentre retrospective study and literature review.
Severe traumatic brain injury (TBI) is the most common cause of disability in children. Refractory increased intracranial pressure can be a therapeutic challenge. Decompressive craniectomy can be proposed when medical management is insufficient, but its place is not clearly defined in guidelines. The aim of this study was to identify prognostic factors in children with TBI. ⋯ This study in a large population confirms that children with severe TBI treated by decompressive craniectomy can achieve a good neurologic outcome. Further studies are needed to clarify the use of this surgery in the management of children with severe TBI.

Gross total resection of large intracranial meningiomas (LIMs) can be challenging and cause significant morbidity and mortality. The aim of this systematic review is to determine the clinical effectiveness and safety of stereotactic radiosurgery (SRS) either as primary or adjuvant therapy for LIMs with tumors ≥2.5 cm in maximum dimension (tumor volume ≥8.1 cm3). A total of 452 tumors in 496 patients (350 female [69.3%] and 146 male [30.6%]) with median age 60 years (48-65 years) were included. ⋯ Subgroup analysis revealed that there is 2-fold greater likelihood of improvement in clinical symptoms in patients with non-SS GKS than SS GKS (odds ratio 2.47; 95% confidence interval 1.38-4.44; P = 0.002). SRS is safe and effective in the treatment of LIMs as primary or adjuvant treatment. Further prospective studies are required to validate our results.

After aneurysmal subarachnoid hemorrhage (aSAH), crystalloid fluids with a relatively high sodium concentration have been used to maintain the cerebral blood flow. However, the prophylactic delivery of water and sodium by intravenous (IV) infusion will not necessarily improve the prognosis of patients after aSAH, and the excessive supply of water and sodium can negatively affect the outcome. We hypothesized that the delivery of an optimal amount of water and sodium separately might improve the outcome after aSAH. ⋯ The separate delivery of optimal amounts of water and sodium could be a promising therapeutic strategy to improve the prognosis after aSAH.

Meta Analysis
Surgery For Clinoidal Meningiomas: Case Series And Meta-Analysis Of Outcomes And Complications.
Clinoidal meningiomas present specific characteristics related to their peculiar site of anatomic origin. Clinical series focusing on pure clinoidal meningiomas are not numerous. We performed a systematic review and meta-analysis, including our own case series, of the available literature to better identify the specific features of these tumors. ⋯ The rate of gross total resection is proportional to the dural origin of these tumors, which is intimately related to critical neurovascular structures. Complementary radiosurgery could represent a valid treatment strategy. Postoperative visual improvement remains less satisfying compared with other suprasellar meningiomas. The introduction of skull-base techniques, such as extradural anterior clinoidectomy, has enabled improvements in visual outcome without any increase in approach-related morbidity.
