To construct a universally applicable nomogram using computed tomography perfusion parameters based on Rapid processing of PerfusIon and Diffusion software for evaluating the prognosis of acute anterior circulation large vessel occlusion treated by endovascular therapy. ⋯ Our nomogram can be used as a simple and reasonable tool to predict the prognosis of acute anterior circulation large vessel occlusion treated by endovascular therapy. The computed tomography perfusion parameter volumes of cerebral blood flow < 30% obtained by Rapid processing of PerfusIon and Diffusion software was an important predictive factor in this model.

Ulnar nerve entrapment at the elbow is a common neurological entrapment neuropathy. Previous research has shown that surgical treatment can be highly successful. Only a few studies have reported on long-term outcome after surgery. In this study, we report on the long-term follow-up after surgery for ulnar nerve compression at the elbow. ⋯ We may conclude that the surgical treatment is also successful in the long term.

The dissection of the Sylvian fissure (SF) is a crucial technique requiring considerable expertise and skills traditionally acquired through years of experience. The continuous decline in surgical case-load necessitates the development of efficient alternative training opportunities. However, building a realistic and effective training simulator for the microsurgical dissection of the SF as an integral part of the neurosurgical curriculum remains a challenging endeavor. This work aims to develop and evaluate a high-fidelity phantom simulator for effective and transferable training of the SF dissection with a focus on middle cerebral artery aneurysm clipping. ⋯ The presented methodology demonstrates that the development and assessment of a high-fidelity hands-on simulator for the focused training of one of the most delicate neurosurgical procedures is achievable in a timely manner and without extensive investments.

We aimed to assess percutaneous pedicle screw (PPS) placement accuracy, fluoroscopy shot number, and operation time using a modified single anterior-posterior (AP) fluoroscopy with a C-arm in treating traumatic thoracic and lumbar vertebral fractures. ⋯ The PPS placement method using modified single AP fluoroscopy for treating traumatic thoracic and lumbar spine fractures was fairly accurate and reduced the number of fluoroscopy shots and operation time. This technique requires only a C-arm for assistance and can be easily mastered by spinal surgeons across hospitals of various levels.

In general, the superior cerebellar artery is the most prevalent vessel that compresses the trigeminal nerve root exit zone (TGNREZ) and is responsible for trigeminal neuralgia (TGN). Nevertheless, the surgical outcome is less efficacious when the offending vessel is a dolichoectatic vertebrobasilar vessel (DVB). In addition, the potential for postprocedural adhesion and fibrosis renders recurrent TGN after prior surgery, an extremely challenging operation. ⋯ A combined transpetrosal approach with microneurovascular transposition technique was selected to achieve all objectives. A case illustration with a surgical video is demonstrated.
