Awake craniotomy (AC) is generally a safe and effective procedure; however, a small but not insignificant portion of cases are aborted due to patient intolerance of the awake portion of surgery. There is not yet a firm understanding of what characteristics indicate patient tolerance or failure of AC. ⋯ AC remains an effective treatment option; the majority of patients tolerate the procedure without issue. Male patients have lower rates of surgical failure, whereas remifentanil administration may increase failure rate.

To define radiologic parameters and the diagnostic accuracy of computed tomography (CT) scan on posterior ligamentous complex (PLC) injury, identified by magnetic resonance imaging (MRI) in patients with thoracolumbar (TL) fracture. ⋯ An RA greater than 16°, SI greater than 20°, and GI greater than 24° were associated with PLC injury in patients with type A TL fractures, and an RA greater than 16° and SI greater than 20° predicted PLC injury in type A1 and A2 fractures. An SI greater than 20°, GI greater than 24°, LKA greater than 26°, and ISD ratio greater than 56% predicted PLC injury in type A3 and A4 fractures.

To investigate the clinical efficacy of navigation-guided minimally invasive surgery in patients with hypertensive basal ganglia hemorrhage. ⋯ Under certain conditions, compared with standard craniotomy and hematoma evacuation, navigation-guided hematoma puncture aspiration and catheter drainage is simple, effective, and safe as a treatment for hypertensive basal ganglia hemorrhage.

Dural arteriovenous fistula (DAVF) at the petrous apex with pial arterial supplies possesses complicated angioarchitecture, associates with aggressive neurologic behaviors, and associates with high risk of complications. This study aimed to summarize our experience with this type of DAVF in the last 15 years. ⋯ Supratentorial draining direction may be a risk factor for venous ectasia and SAH in petrous apex DAVFs with pial arterial supplies. The feeding pial arteries appeared to be at risk of embolization-related hemorrhagic complication and are therefore suggested to be embolized first.
