Anatomical dissection is a fundamental part of surgical education, but it can be challenging to visualize the subtle details of anatomy. Full-spectrum photography (FSP) is a technique that uses cameras that can capture light in a wider range of wavelengths compared to traditional cameras. This technical laboratory note introduces a method using noncontrast-dependent FSP to improve the visualization of neuroanatomical structures during cadaveric dissection for surgical neuroanatomy. ⋯ FSP offers a valuable enhancement to anatomical dissections and education. It provides a noninvasive means to characterize anatomical structures with greater clarity, highlighting features that may be challenging to observe with the naked eye or standard visible-light photography.

The impact of statin pretreatment on outcomes for patients undergoing endovascular treatment of intracranial aneurysms remains uncertain. We aimed to conduct a systematic review and meta-analysis evaluating the efficacy and safety of statins in this population. ⋯ Statin pretreatment may decrease the risk of hemorrhagic complications and in-stent stenosis after endovascular aneurysm therapy but does not improve angiographic occlusion. An increased hazard of ischemic events was found. Further data are needed to validate these findings and clarify the role of statins in patients with aneurysms undergoing endovascular procedures.

To investigate the effect of intravertebral cleft sclerosis on the efficacy of percutaneous vertebroplasty (PVP) in osteoporotic vertebral compression fractures (OVCFs). ⋯ IVCs affect cement distribution and recovery outcomes, with IVCns achieving better results. Early treatment is advised for OVCF with intravertebral clefts.

Prognosis of adult tuberculous meningitis patients undergoing a ventriculoperitoneal (VP) surgery is not well known. Prognostic models developed to predict the prognosis might help the clinicians immensely. ⋯ About 39% adult tuberculous meningitis patients die or remain disabled after VP shunt surgery. MRC grade III illness, papilledema, seizures and size of hydrocephalus are the most important baseline predictors that can help in prognostication. The nomograms developed may help the treating physician in prognostication.

Moyamoya disease (MMD) is a rare cerebrovascular disorder marked by internal carotid artery narrowing, collateral neovascularization, and symptomatic cerebral ischemia. Select patients can benefit from direct bypass (STA-MCA bypass) by restoring blood flow to hypoperfused territories. Symptomatic contralateral stroke (CS) following STA-MCA bypass is a devastating, poorly understood complication. We investigate clinical and radiographic risk factors influencing CS incidence after bypass surgery. ⋯ CS patients following bypass had significantly higher pre-operative SBP, post-operative SBP goals below their average pre-operative SBP, and longer time from symptom onset to surgery compared to patients without CS. Patient-specific post-operative SBP management and timely surgical revascularization are crucial for preventing CS in MMD patients undergoing STA-MCA bypass.
