The number of patients with a history of clipping of recurrent aneurysms after coil embolization has increased. The aim of this article was to report the feasibility of CT angiography using a commercial metal artifact reduction algorithm (Smart Metal Artifact Reduction [MAR]) for patients who underwent clipping of recurrent aneurysms after coil embolization. ⋯ For patients with a history of clipping of recurrent aneurysms after coil embolization, CT angiography using MAR is feasible, although further development of imaging techniques is needed.

To investigate effects of using a large-sized coil first on embolizing cerebral aneurysms compared with conventional coils. ⋯ The use of a large-sized coil as the first one for embolizing cerebral aneurysms may be a better embolization strategy because it achieves similar initial occlusion rates, decreased packing density, decreased coil numbers and lengths, and reduced recurrence prevalence at follow-up.

The combined transpetrosal approach is a complicated skull base surgery with a high degree of difficulty. Herein, we made a 3-dimensional (3D) printed petrous bone with color-coded anatomic sites and evaluated its usefulness as a model to practice drilling associated with combined transpetrosal surgery. ⋯ These results indicate that our 3D printed model is very useful for practice with craniotomy and petrosectomy drilling, necessary in the combined transpetrosal approach.

Neurosurgery is a unique field, which would benefit greatly from increased global collaboration, furthering research efforts. ResearchGate is a social media platform geared toward scientists and researchers. ⋯ ResearchGate may be a useful platform to increase neurosurgical networking and research collaboration. Its novel bibliometrics are strongly correlated with more classic platforms.

The supraorbital keyhole craniotomy is a well-established minimally invasive approach for the treatment of intracranial aneurysms. However, the surgical range of exposure using this technique for treatment of intracranial aneurysms has not been studied. ⋯ Although the SO is conventionally used in the treatment of anterior circulation aneurysms, we were able to treat aneurysms over a range of 50 mm over the skull base. With its low complication risk, relatively short hospital stay, and excellent cosmetic results, SO remains a valuable treatment option for both young and aged patients.
