Targeted epidural blood patch (EBP) at the site of a presumed cerebrospinal fluid leak reportedly has better outcomes than non-targeted EBP; however, it is associated with a higher risk of wrong-site injection, such as iatrogenic subarachnoid or intramuscular injections, which lead to reintervention because of the insufficient coverage of injected blood. ⋯ O-arm-guided navigation facilitated EBP by enabling real-time observations of the needle trajectory and distribution of injected blood while simultaneously avoiding major complications, such as wrong-site injections or reintervention.

Traumatic injuries, degenerative/rheumatologic conditions, tumors, or infections of the upper cervical spine may in certain circumstances require surgical stabilization. C1 lateral mass screws (Harms technique) in combination with C2 instrumentation (pars, pedicle, translaminar screws) have become a mainstay of surgical treatment. The surgical anatomy of the C1 lateral mass can be challenging especially with the robust venous plexus that often causes significant bleeding with exposure of the C1-C2 articular complex. The purpose of this study was to examine whether the use of navigation reduced intraoperative blood loss during atlantoaxial fixation. ⋯ In our series, surgical navigation significantly reduced blood loss compared with non-navigated cases without increasing surgical time or risk of complication. Furthermore, navigation has the potential to reduce operative times due to a reduction in blood loss.

Although microvascular decompression (MVD) surgery is considered the gold standard treatment for hemifacial spasm, there are some MVD-related complications. ⋯ MVD operation is a safe treatment for hemifacial spasm. Facial nerve palsy is the most common MVD-related complication; preservation of the lesser occipital nerve during MVD surgery can decrease the rate of occipital sensory disturbance. Permanent or serious complications are comparatively rare in MVD surgery.

Health care-associated meningitis and ventriculitis (HCAMV) occurs in adults with intracranial hemorrhage (ICH) and is associated with high rates of morbidity and mortality, but the prognostic impact of this infectious complication in a controlled matched study of ICH is unknown. ⋯ HCAMV has a significant prognostic impact in adults with ICH.

The type of pituitary adenoma with a manifestation that includes cavernous sinus syndrome is rare. Based on the clinical data of 70 patients, this study investigated the pathogenesis, imaging characteristics, and prognostic factors of pituitary adenoma with cavernous sinus syndrome. ⋯ The prognosis of cavernous sinus syndrome differs depending on the mechanism of the syndrome. There was no significant difference in the prognosis between patients with total pituitary adenoma resection and subtotal resection. Timely surgery within 100 days of symptom occurrence, Knosp grade 0-2, and associated pituitary apoplexy are predictive factors of good prognosis.
