Objective: The sitting position has historically offered neurosurgeons important advantages including improved venous drainage and clearing of blood from the operative field due to gravity, a reduced need for cerebral or cerebellar retraction, especially surgical treatment posterior fossa pathologies. Nonetheless, operating in widely fallen out favor perceived risk positioning-related complications, namely, air embolism (VAE). objective this study was describe incidence predictors...

Introduction: Moyamoya disease is characterized by spontaneous and progressive occlusion of the intracranial carotid arteries their most proximal branches. One current treatments involves a combined surgical revascularization technique: direct with superficial temporal artery to middle cerebral (STA-MCA) bypass, along indirect using encephaloduroarteriosynangiosis (EDAS). Despite some STA-MCA bypasses occluding over time, perfusion clinical status surprisingly remain unaffected. Given that...

INTRODUCTION: While well-established in Moyamoya Disease (MMD), the role of direct superficial temporal artery (STA) to middle cerebral (MCA) bypass non-Moyamoya (N-MMD) steno-occlusive syndromes remains controversial. Nonetheless, recurrent stroke risk N-MMD patients high despite best medical management. METHODS: Single-center retrospective review STA-MCA cases from 2014–2023 was performed. Cases were excluded if they involved double-barrel bypass, interposition grafts, or surgical...

Faster trains require tilting of the cars to counterbalance centrifugal forces during curves. Motion sensitive passengers, however, complain discomfort and overt motion sickness. A recent study comparing different control systems in a train, suggested that delay car tilts relative curve track contributes Other aspects stimuli, like lateral accelerations jitters, differed between tested conditions prevented final conclusion on role tilt delay. Nineteen subjects were motorized 3D-turntable...

Introduction: Skull base approaches for managing complex pathologies often entail substantial bone removal, posing challenges cranial vault reconstruction due to loss during drilling. The resulting flap is frequently insufficient in size and necessitates extension with titanium mesh or fixation plates. This process labor-intensive, costly, suboptimal both cosmetically functionally. In cases involving pathologic conditions such as en plaque meningioma infiltrating bone, post-surgery...

OBJECTIVE Although well-established in moyamoya disease (MMD), the role of direct superficial temporal artery (STA) to middle cerebral (MCA) bypass non-MMD (N-MMD) cerebrovascular steno-occlusive syndromes remains controversial. Nonetheless, recurrent stroke risk patients with N-MMD, despite best medical management, exceedingly high—especially for those suffering from hypoperfusion-related ischemia. The study objective was determine relative safety and efficacy profiles STA-MCA surgery MMD...
