Journal of Neurosurgery, Ahead of Print. OBJECTIVE The aim of this study was to examine the impact of deliberate employment of postoperative hypotension on delayed postoperative hemorrhage (DPH) for all Spetzler-Ponce Class (SPC) C brain arteriovenous malformations (bAVMs) and SPC B bAVMs ≥ 3.5 cm in diameter (SPC B 3.5+).… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE The purpose of this study was to adapt and apply the extended definition of favorable outcome established for Gamma Knife radiosurgery (GKRS) to surgery for brain arteriovenous malformations (bAVMs). The aim was to derive both an error around the point estimate and a model incorporating angioarchitectural features in order to facilitate comparison among different treatments.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE The aim of this study was to confirm the feasibility of an innovative transoral robotic surgery (TORS), using the da Vinci Surgical System, for patients with sellar tumors. This technique was designed to offer a new minimally invasive approach, without soft-palate splitting, that avoids the rhinological side effects of classic endonasal approaches.… Read More...

Journal of Neurosurgery, Ahead of Print. The authors describe a safe entry zone, the superior fovea triangle, on the floor of the fourth ventricle for resection of deep dorsal pontine lesions at the level of the facial colliculus. Clinical data from a patient undergoing a suboccipital telovelar transsuperior fovea triangle approach to a deep pontine cavernous malformation were reviewed and supplemented with 6 formalin-fixed adult human brainstem and 2 silicone-injected adult human cadaveric heads using the fiber dissection technique to illustrate the utility of this novel safe entry zone.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE The durability of embolization of large aneurysms is enhanced by use of the neck-bridging stent. However, it remains unclear what factors contribute to decreased recanalization. The purpose of this study was to demonstrate the contribution of the straightening effect of the parent artery to the durability of stent-assisted coiling for large aneurysms.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE The pathogenesis of cerebral aneurysms (CAs) remains largely unknown. Long noncoding RNAs (lncRNAs) were reported recently to play crucial roles in many physiological and biological processes. Here, the authors compared the gene-expression profiles of CAs and their control arteries to investigate the potential functions of lncRNAs in the formation of CAs.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVE Phosphatidylserine (PS) is a major component of the inner leaflet of membrane bilayers. During cell activation or apoptosis, PS is externalized to the outer membrane, providing an important physiological signal necessary for the release of the microparticles (MPs) that are generated through the budding of cellular membranes.… Read More...
