Meta Analysis
Role of Apolipoprotein E Genotypes in Aneurysmal Subarachnoid Hemorrhage: Susceptibility, Complications, and Prognosis.
Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating disease. Emerging evidence has indicated that the apolipoprotein E (ApoE) genotype might be associated with the risk of aSAH as well as complications and outcomes after aSAH, although the results remain controversial. ⋯ We found that the ApoE genotype was significantly associated with aSAH risk, whereas its effect on certain ethnic populations differs. Patient carrying the ε4 allele might have a worse outcome, whereas current evidence was insufficient to prove the association between ApoE genotypes and post-SAH complications.

Cerebrospinal fluid (CSF) leakage is one of the most challenging complications in neurosurgery. We sought to evaluate the efficacy of dural sealants in preventing CSF leakage after cranial surgery. ⋯ This systematic review showed that dural sealants did not reduce the number of CSF leaks in general, the number of incisional CSF leaks alone, or the number of pseudomeningocele formations alone. However, dural sealants reduced the risk of surgical-site infection.

Review Case Reports
Distinguishing Falcine Chondrosarcomas from Their Mimics and Management.
Primary intracranial chondrosarcoma is an extremely rare malignant tumor of the central nervous system, which accounts for <0.16% of all primary intracranial tumors. This rare tumor has a high associated morbidity from the tumor itself as well as from treatment modalities. ⋯ Dural chondrosarcoma is a possible entity in the differential diagnosis of a presumed meningioma, particularly when atypical features are present. We report a grade 1 intracranial chondrosarcoma of the classical subtype without any neurologic problems after complete surgical excision. The patient did not receive any adjuvant therapy and at 26 months' follow-up showed no recurrence.

Review Case Reports
Treatment of Partially Thrombosed Intracranial Aneurysms: Single-Center Series and Systematic Review.
Partially thrombosed intracranial aneurysms (PTIAs) represent a challenging subgroup of aneurysms, with an organized intraluminal thrombus and a solid mass, in which the optimal therapeutic strategy is discussed controversially because of limited data. We therefore analyzed the results of surgical and endovascular treatment in patients with PTIAs treated in our department and combined the results with a systematic literature review. ⋯ In this study, surgical treatment of PTIAs showed superior initial radiologic results and better long-term stability than endovascular treatment. Therefore, surgical treatment should be considered in those patients harboring PTIAs who are qualified as suitable surgical candidates after interdisciplinary consensus.

Conventional external beam radiation and stereotactic radiosurgery are common radiation techniques used to treat spinal tumors. Intraoperative brachytherapy (BT) may serve as an alternative when other options have been exhausted or as an adjunct in combination with other therapies. The objective of this study was to systematically review the literature on BT use in spinal tumor surgery. ⋯ BT was used to treat metastatic disease in patients who failed previous therapies and could not tolerate open surgery or further therapy. This review summarizes the major findings in the available literature pertaining to patient background, indications, and outcomes. Spinal BT seems to be a viable option for spine tumor treatment and should be made available at treating centers.
