Comparative Study
Awake craniotomy anesthesia: A comparison between the monitored anesthesia care versus the asleep-awake-asleep technique.
Commonly used sedation techniques for an awake craniotomy include monitored anesthesia care (MAC), using an unprotected airway, and the asleep-awake-asleep (AAA) technique, using a partially or totally protected airway. We present a comparative analysis of the MAC and AAA techniques, evaluating anesthetic management, perioperative outcomes, and complications in a consecutive series of patients undergoing the removal of an eloquent brain lesion. ⋯ Both the MAC and AAA sedation techniques provide an efficacious and safe method for managing awake craniotomy cases and produce similar perioperative outcomes, with the MAC technique associated with shorter operative time.

The management of high-grade glioma (HGG) has been affected by recent landmark trials and is now more proactive. More aggressive treatment leads to hospitalization due to side effects, however. Space-occupying tumor bed cysts have been described, but not systematically assessed. We sought to analyze this complication in a contemporary HGG cohort. ⋯ In modern neuro-oncology, the rate of tumor bed cysts complicating HGG management appears stable compared with historical data. Shunt implantation is feasible and effective. We propose a classification system as a common data element for comparison across future studies.

Review Meta Analysis Comparative Study
Clipping versus coiling, in anterior circulation ruptured intracranial aneurysms: A meta-analysis.
To evaluate open surgical versus endovascular repair of anterior circulation ruptured intracranial aneurysms based on operative mortality, permanent neurologic deficit, late mortality, and need for reintervention. ⋯ Selection of the appropriate procedure must be made on the basis of the special characteristics of each case.

Review Meta Analysis
Membranectomy in Chronic Subdural Hematoma: a Meta-Analysis.
Initial management strategies of chronic subdural hematoma (cSDH) are controversial and range from bedside twist-drill or burr-hole drainage to craniotomy with membranectomy (CWM). We aim to 1) perform a meta-analysis of the available data on the outcomes of CWM for treatment of cSDH in published English-language literature and 2) evaluate collective outcomes of CWM with respect to morbidity, mortality, and recurrence rates. ⋯ Clinical data on outcomes of CWM in cSDH are limited to single institutional analyses, with considerable variation in recurrence rates and follow-up time. The rates we reported are comparable with the 5% mortality and 3%-12% morbidity rates and lower than the 10%-21% recurrence rate in the literature for burr holes or craniotomy without membranectomy. This meta-analysis provides an in-depth analysis of available data and reviews reported outcomes.

Review Meta Analysis
Chiari Malformation Type 1: A Systematic Review of Natural History and Conservative Management.
Chiari malformation type 1 (CM-1) is a variation of hindbrain development that can sometimes occur in asymptomatic individuals. Conventional treatment is surgical decompression, but little is known about the natural history of patients who do not undergo surgical management. This information is critical to determine how these patients should be managed. We conducted a systematic literature review to determine the natural history of CM-1, particularly in patients who did not undergo surgery and in asymptomatic individuals, to help patients and physicians determine when surgery is likely to be beneficial. ⋯ The natural history of mild symptomatic and asymptomatic CM-1 in adults is relatively benign and nonprogressive; the decision to perform surgical decompression should be based on severity and duration of a patient's symptoms at presentation. It is reasonable to observe a patient with mild or asymptomatic symptoms even in the presence of significant tonsillar descent or syringomyelia.
