Intracranial aneurysms (IAs) can be treated through endovascular treatment (EVT) or microsurgery (MS). Treated IAs can recanalize, which can lead to rupture or retreatment. ⋯ The rate of IA retreatment is low; however, the rate of hemorrhage/rupture from treated IAs is even lower. A higher rate of retreatment was noted in EVT-treated IAs versus MS-treated IAs and in ruptured IAs versus unruptured IAs; however, the rate of hemorrhage or rerupture was comparable between the groups.

The ideal treatment method for cranial arachnoid cysts stills controversial, each of endoscopic and microscopic techniques has its pros and cons. ⋯ The fenestration through the lateral pontomesencephalic membrane created a shortcut of cerebrospinal fluid flow to the basal cisterns especially cerebellopontine cistern and represents a reliable option with an acceptable success rate. It creates a good drainage to the large cysts.

TEMPORAL ANEURYSMORRHAPHY TECHNIQUE FOR THE MANAGEMENT OF COMPLEX MIDDLE CEREBRAL ARTERY ANEURYSM: A VIDEO CASE.
A 57-year-old man who had previously suffered a transient episode of retrograde amnesia was admitted to the vascular department of the Burdenko Neurosurgical Center. Computed tomography angiography revealed a complex trifurcation aneurysm of the right middle cerebral artery (MCA) bifurcation. There were no clear focal symptoms after the neurologic examination. ⋯ Thus the M2 cutting-off with an insulating clip and temporal aneurysmorrhaphy were options that allowed for adequate final clipping. There were no intraoperative or postoperative complications. The patient remained neurologically intact and was discharged 7 days after surgery (Figure 1).

Review Meta Analysis
Heart rate variability as a predictor of mortality in traumatic brain injury: a systematic review and meta-analysis.
To systematically review the medical literature to determine the utility of heart rate variability in predicting mortality for moderate to severe traumatic brain injury. ⋯ This meta-analysis predicted high mortality based on odds ratio for variables low-frequency/high-frequency ratio, high-frequency peak, and TP. However, the statistical analysis was weakened owing to the high level of heterogeneity in the included studies. Further research is needed to generate high-quality recommendations regarding heart rate variability as a predictor of mortality after traumatic brain injury.

Review Meta Analysis
Treatment Outcomes of Intracranial Myeloid Sarcomas: A Meta-Analysis.
Intracranial myeloid sarcomas (IMS) are rare central nervous system manifestations of malignant hematopoietic neoplasms of myeloid origin such as acute myeloid leukemia and chronic myeloid leukemia. Reported cases in the literature are limited to primarily case reports. We present a systematic review of this rare central nervous system tumor, characterizing the clinical presentation, tumor location, histopathology, and available treatment modalities. We correlate these variables with mortality, recurrence, and complications to suggest optimal management strategies for IMS. ⋯ The use of adjuvant radiotherapy or chemotherapy for IMS significantly reduces mortality, confirming IMS as a cranial manifestation of a systemic disease. Although surgical treatment is indicated for histopathologic diagnosis and to relieve mass effect, the extent of resection does not predict overall survival.
