Previous studies have indicated traumatic brain injury (TBI) as a risk factor for stroke and myocardial injury. Whether TBI increases new onset of major adverse cardiovascular and cerebrovascular events (MACCE) is not well established. ⋯ Our results showed that patients with TBI have a significantly greater risk of MACCE than the control group. We hope this information will remind critical-care physicians and neurosurgeons to keep in mind the long-term effects of TBI on MACCE.

Cerebrospinal fluid (CSF) leak is a common complication after surgeries involving sellar reconstruction. Various techniques, including the nasoseptal flap, have been developed to limit postoperative CSF leak. However, the nasoseptal flap causes complications owing to donor site morbidity. A free mucosal graft may be just as effective in reducing CSF leaks as well as reducing postoperative nasal discomfort. This study aimed to assess operative outcomes of free mucosal graft after pituitary resection. ⋯ The free mucosal graft is a simple and effective means of sellar reconstruction in patients undergoing endonasal endoscopic pituitary resection, and its efficacy is similar to nasoseptal flaps. The free mucosal graft technique does not worsen sinonasal morbidity postoperatively.

Spine pathology is a common reason for admission to neurosurgical units in low- and middle-income countries (LMICs) and can have high morbidity rates from lack of specialized institutes. However, good surgical outcomes and quality-of-life scores have been reported in LMICs. This study details the complication rates and predictive factors from spine surgery at a large hospital in Cambodia, aiming to identify high-risk patients to improve surgeon understanding of these complications for improved pre-operative planning and patient counseling. ⋯ Many factors play a role in spine surgery complications in LMICs, including limited access to intra-operative technology, low follow-up rates, and minimal physiotherapy and rehabilitation capabilities. Patients with long delays in presentation, American Spinal Injury Association grade A injuries, and lumbar-level surgery may be especially susceptible to complications and postoperative morbidity. Despite this, institutions have reported encouraging spine trauma outcomes, and spine surgeries are becoming more accepted and safe operations in many LMICs.

We retrospectively analyzed treatment efficacy and identified prognostic factors impacting tumor control and survival in patients with brain metastases from cancer of unknown primary (CUP) treated with gamma knife radiosurgery (GKRS). ⋯ Our findings suggest that GKRS is a relatively effective and safe treatment for control of tumor progression in patients with brain metastases from CUP. Overall and neurologic survivals were short, but we recommend GKRS treatment to prevent early neurologic dysfunction and death in patients with CUP.

Angiogenesis has been shown to be strictly related to tumor malignancy. Glioblastoma (GBM) is highly vascularized and von Willebrand Factor (VWF) plays a potent proangiogenic role. Dynamic contrast-enhanced and dynamic susceptibility contrast magnetic resonance imaging (MRI) represent a widely accepted method to assess GBM microvasculature. Our aim was to investigate the correlation between plasma VWF:Ag, permeability, and perfusion MRI parameters and examine their potential in predicting GBM patient prognosis. ⋯ These findings, in a small group of patients, suggest a role for VWF:Ag, similar to Ktrans, and Kep as a prognostic indicator of postoperative survival of patients with GBM.
