This study examined the clinical significance of residual hyperintense area on T2-weighted magnetic resonance imaging (T2R) without gadolinium-enhanced lesions at the end of initial treatment (debulking surgery, concomitant radiotherapy, and temozolomide) in patients with glioblastoma. ⋯ The T2R at the end of initial treatment can predict local recurrence. However, the distant recurrence occurred frequently in T2D group. Thus, attention should be paid to local recurrences in T2R group and distant recurrences in T2D group.

Global Neurosurgery has been described as the clinical and public health practice of neurosurgery with the primary purpose of ensuring timely, safe, and affordable neurosurgical care to all who need it. Global Neurosurgery activities in the form of mission trips, educational partnerships, and research collaborations have been in place for decades. Still, there have been no central organizing efforts to improve the harmonization of these endeavors until recently. ⋯ The Boston Declaration seeks to further define a unified vision of progress as Global neurosurgery continues to grow and evolve. This ambitious initiative will review existing evidence, employ on-the-ground expert experience, and seek broad inclusivity and transparency to formulate a new set of goals for global neurosurgery and a structure that shifts the agency to low- and middle-income country actors. We propose a path to developing a new consensus statement and action plan, the 2025 Boston Declaration for Global Neurosurgery.

Thoracic dorsal arachnoid webs are intradural membranes that may cause obstruction of cerebrospinal fluid flow and spinal cord compression. Although well recognized, they are rare and there is a paucity of long-term data on their natural history and prognosis. We reviewed radiographic features, surgical indications, and pathologic specimens of patients diagnosed with focal thoracic dorsal arachnoid webs. ⋯ Most patients in a large series of patients with dorsal arachnoid webs did not undergo surgical intervention, but those with myelomalacia and syrinx experienced radiographic and clinical deterioration without surgery. Surgery to treat symptomatic arachnoid webs results in significant clinical improvement with low surgical morbidity.

To investigate the effect of microcatheter shaping based on the parent artery mainstream line of blood flow simulated using the computational fluid dynamics (CFD) technique on embolization of unruptured aneurysms on the posterior wall of the anterior cerebral artery (ACA) A1 segment. ⋯ Use of computational fluid dynamics simulation of parent artery blood flow for microcatheter shaping in the embolization of unruptured aneurysms on the posterior wall of the ACA A1 segment is safe and effective in navigating the microcatheter to the right location for embolization, resulting in good stability and support for the embolization.

Unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) is an advanced, minimally invasive spinal surgical technique characterized by the use of 2 discrete portals-one for clear visualization and continuous irrigation and the other for the dexterous manipulation of surgical instruments. This configuration not only affords an expanded view (0° or 30°) but also enhances the freedom of movement for instruments, thereby augmenting the precision and flexibility of the surgery. The superiority of UBE-TLIF lies in its capacity to facilitate rapid postoperative recovery with minimal trauma, reduced intraoperative bleeding, abbreviated hospital stays, and significant amelioration of postoperative lower back pain. ⋯ This technique reduces neural irritation during the procedure, leading to an improved patient experience postoperatively. UBE-TLIF offers a safe, efficacious, and swiftly recuperative minimally invasive option for the treatment of lumbar degenerative diseases. It diminishes reliance on costly equipment, thereby facilitating the dissemination and application of this technology in community hospitals.7.
