Review
Skull base venous anatomy associated with endoscopic skull base neurosurgery: a literature review.
An understanding of the anatomy and function of the skull base venous channels is fundamentally important for safe performance of endoscopic surgery for skull base lesions. This review focuses on 4 skull base venous channels-namely, the intercavernous sinuses, basilar plexus, osseous veins, and inferior petroclival vein-because these have been less recognized by neurosurgeons than other major venous channels such as the inferior petrosal sinus. We reviewed the literature concerning these 4 venous channels and discussed their anatomy and function. ⋯ Because of their location, they occasionally obstruct the surgical view and are sometimes implicated in intraoperative hemorrhage, air embolism during endoscopic skull base surgery, and postoperative hematoma. They usually function as a venous reservoir of cranial venous drainage; however, they are less often directly involved in normal brain perfusion. Knowledge about the functional and morphologic anatomy of the skull base venous channels is important for neurosurgeons to avoid unexpected complications during endoscopic skull base surgery.

Determining the value of the computed tomographic black hole sign in predicting postoperative rehemorrhage in patients with intracranial hemorrhage (ICH) underwent minimally invasive surgery (MIS). ⋯ The black hole sign on initial CT could predict the postoperative rehemorrhage following the minimally invasive procedures.

Randomized Controlled Trial
One center's experience with Hybrid technique for lumbar spine instrumentated surgeries: evaluation of different instrumentation systems and their management.
Minimally invasive surgery (MIS) has been providing many solutions in spine surgery, and several technical variations and instrumentation systems are available. The aim of our study is to investigate the best system to perform a hybrid technique in lumbar spine fusion procedures. ⋯ Precept Modular seems to be the most useful system when performing hybrid technique in lumbar fusion procedures. Furthermore, it results in the only one that provides the opportunity to easily and quickly switch from minimally invasive surgery to open surgery, avoiding muscles' injuries.

The blood-brain barrier (BBB) of patients with moyamoya angiopathy (MMA) is unstable, which may contribute to transient neurologic symptoms (TNS) after direct bypass surgery. However, BBB-related proteins have never been investigated. The purpose of this study was to evaluate the perioperative serum levels of biomarkers representing BBB function in MMA patients based on the hypothesis that postoperative hemodynamic change may disrupt the BBB. ⋯ Marked changes in biomarkers representing the tight junction of the BBB were observed. These preliminary results suggest that marked hemodynamic change and TNS in some patients are associated with disruption of the BBB after direct bypass surgery for MMA.

Comparative Study
Comparison of heterotopic ossification after fixed- and mobile-core cervical disc arthroplasty.
To compare the heterotopic ossification (HO) between cervical disc arthroplasty (CDA) with fixed- and mobile-core prosthesis and to compare the clinical and radiographic outcomes. ⋯ The fixed-core prosthesis had a greater incidence of HO than mobile-core prosthesis after CDA. However, both CDA with fixed- and mobile-core prostheses obtained good clinical outcomes and maintained cervical sagittal alignment.
