Embolization of the middle meningeal artery (MMA) has recently been proposed as an alternative to surgery for treatment of chronic subdural hematoma (SDH). There is increasing evidence that fragile neovasculature arising from distal branches of the MMA found within the membrane that forms around a chronic SDH is responsible for high recurrence rates due to chronic, repeated rebleeding. Embolization of the MMA could thus potentially eliminate the blood supply to this membrane and prevent further rebleeding. ⋯ In this case series of 6 patients harboring 7 recurrent, chronic SDHs, 6 of the 7 were successfully treated with MMA embolization and able to avoid surgery for reevacuation, suggesting that this minimally invasive technique may represent an effective alternative to surgery.

Filum Terminale Arteriovenous Fistulas with Multiple Shunt Points: A Report of Two Exceptional Cases.
Filum terminale arteriovenous fistula (FTAVF) with multiple shunt points has not been reported in the literature. In previous studies, the angioarchitecture of FTAVFs was always featured with only one single shunt point, and such a uniformity had established the preconceived and conventional understanding of FTAVFs for clinicians. ⋯ The exceptional finding of these 2 cases is a renewal of the conventional understanding of FTAVFs, not only for the angioarchitecture of the lesions but also for the treatment strategy.

Neuronavigation systems are routinely used during neurosurgical procedures. Currently, new imaging technologies are emerging, such as virtual, augmented, and mixed reality. With mixed-reality devices, the user can analyze and interact with the real environment using virtual objects. The aim of this prospective pilot study was to offer a proof of concept by testing the clinical feasibility and accuracy of a wearable mixed-reality device (Hololens) for preoperative neurosurgical planning. ⋯ This prospective clinical study offers a proof of concept of the clinical feasibility of the Hololens for brain tumor surgery planning in the operating room, with quantitative outcome measures. Further development is needed to improve the accuracy of this wearable mixed-reality device.

To identify the top 50 most-cited articles in the literature focusing on thoracolumbar spine fractures. ⋯ Thoracolumbar fractures are the most common injuries of the spine, and the incidence is increasing globally. To understand current treatment guidelines and how treatment of these fractures has evolved, it is important to know the most-cited articles pertaining to these fractures.

Spinal cord intramedullary cavernous malformation (SICM) is kind of rare vascular disease, and the therapeutic strategy is still under debate. The purpose of this article is to analyze outcome of SICM surgical resection and to find the possible factors indicating a better outcome. ⋯ The finding suggests that if total resection of SICM is achievable, surgical therapy could be considered to avoid risks of severe complications followed by lesion bleeding. Early microsurgical resection (usually within 3 months) for patients with SICM can lead to better clinical outcomes.
