Distal ophthalmic artery (OpA) aneurysms are a rare subset of vascular lesions with lack of optimal treatment. The management of these aneurysms may require complete occlusion of the parent vessel, carrying a risk of permanent visual impairment due to individual variations of extracranial collateral flow to the intraorbital ophthalmic artery (iOpA). ⋯ This study demonstrates the feasibility of a novel revascularization technique of the iOpA using 2 different transorbital approaches. These techniques can be used in the management of intraorbital lesions such as OpA aneurysms, tumoral infiltrations, or intraoperative injuries.

We aimed to compare flat detector computed tomography cerebral blood volume (FD-CBV) imaging to single-photon emission computed tomography (SPECT) as an adjunctive technique during balloon test occlusion (BTO) in patients with intracranial aneurysms or tumors. ⋯ The patients with decreased CBF on SPECT also showed decreased FD-CBV in the ipsilateral hemisphere. FD-CBV imaging may be useful as an adjunctive technique for BTO before potential therapeutic carotid artery occlusion.

The recent emphasis on simulation-based training in neurosurgery has led to the development of many simulation models and training courses. We aim to identify the currently available simulators and training courses for neurosurgery, assess their validity, and determine their effectiveness. ⋯ With the advent of increasing neurosurgery simulators and training tools, there is a need for more validity studies. Further attempts to investigate translational outcomes to the operating theater when using these simulators is particularly warranted. More training tools incorporating full-immersion simulation and nontechnical skills training are recommended.

Although external landmarks and trajectories for external ventricular drainage have been described for the freehand-guided method, no standard trajectory has been reported for deep-seated intracerebral hemorrhage (ICH). This article presents a freehand-guided catheter insertion technique for deep-seated spontaneous ICH using external landmarks. ⋯ For patients with basal ganglia hemorrhage, freehand-guided catheter insertion and hematoma aspiration with subsequent fibrinolysis is a feasible procedure that shortens procedural times. The described technique could be used as an alternative method because it can be performed when the patient is in a critical state without additional equipment.
