Mini-craniotomy for chronic subdural hematoma (CSDH) is associated with lower rates of recurrence. However, the procedure is performed mostly with the patient under general anesthesia (GA) and therefore frequently requires an intensive care unit (ICU) facility, especially in the elderly population. Because of the unavailability of ICU beds, and to avoid GA, we started to perform this procedure with the patient under local anesthesia (LA). ⋯ Mini-craniotomy for CSDH under LA is an equally effective procedure compared with mini-craniotomy under GA. In addition, it minimizes the risks of GA in the elderly population and obviates the need of a postoperative ICU bed. It also reduces operative time and hospital stay as compared with GA.

Ventriculoperitoneal shunt (VPS) is a common procedure in daily neurosurgical practice. According to some reports, the rate of intracerebral hemorrhage secondary to VPS in patients with no bleeding tendency can be 43.1%; however, symptomatic intracerebral hemorrhage (SICH) secondary to VPS is rare with only sporadic cases reported in adults. To further elucidate the characteristics, mechanism, management, and prognosis of SICH secondary to VPS, we performed a retrospective study in our institution and a systematic review of the literature. ⋯ SICH is a rare complication after VPS in adults without bleeding tendency. The mechanism is obscure, management is challenging, and prognosis is dismal. Future prospective study is anticipated.

Comparative Study
A CT-based Comparison of Abnormal Vertebrae Pedicles between Dystrophic and Nondystrophic Scoliosis in Neurofibromatosis Type 1.
To explore the prevalence and distribution of abnormal vertebral pedicles in scoliosis secondary to neurofibromatosis type 1 (NF1-S) and to compare the abnormal vertebrae pedicles between dystrophic and nondystrophic scoliosis. ⋯ There is a significantly high prevalence of abnormal pedicles in patients with NF1-S and an increased rate of abnormal pedicles in dystrophic scoliosis compared with nondystrophic ones. The described pedicle classification system could serve as an objective tool to guide preoperative assessment.

The purpose of this study was to clarify the clinical and molecular characteristics associated with long-term survival in patients with glioblastoma. ⋯ Younger age and better preoperative KPS score were the characteristics associated with LTSs as compared with STSs. MGMT promoter methylation was associated with mLTSs, but not with LTSs. In addition, lack of SVZ involvement and loss of 19q might be prognostic for longer survival.

To compare the outcomes between patients older and younger than 65 years who underwent single-level minimally invasive transforaminal interbody fusion (MI-TLIF) surgery. ⋯ MI-TLIF presented similar safeness and acceptable outcomes and complication rate in both groups. Cyst formation may be aggravated by cage subsidence, because cage subsidence was a useful potential predictor of cyst formation.
