One of the most challenging aspects of the surgical treatment of tuberculum sellae meningioma is to control the involvement of the inferomedial side of the optic nerve, which is not directly visualized by an ipsilateral approach and thus requires optic nerve mobilization. ⋯ This approach allowed lower mobilization of the compromised optic nerve, better preservation of the vascularization of the visual pathways, and direct access to the inferomedial side of the optic nerve.

Shunt series (SS) are a common diagnostic tool used to verify shunt integrity. SS include X-ray films of the skull, chest, and abdomen and often are performed either when a shunted patient presents with suspected shunt malfunction or as a screening test to identify shunt disconnections or dislodgment. EOS low-dose biplanar X-rays are associated with significantly reduced radiation doses compared with ordinary X-rays and are used for various indications. This is the first publication on the use of EOS as a SS technique. ⋯ These preliminary results suggest that EOS may be used as an alternative technology to demonstrate shunt integrity instead of regular X-ray SS. Favorable shunt visibility without the need for multiple radiation exposures and image processing (such as stitching) results in a significantly shorter examination time and significant less radiation.

Inflow into an aneurysm sac immediately following flow diverter (FD) treatment is an assumed cause of delayed aneurysmal rupture. The significance of delayed posttreatment residual flow occurring months after FD treatment is unknown. ⋯ Our findings suggest that delayed post-treatment residual flow into an aneurysm may form part of the normal clinical course post FD placement and may not preclude eventual thrombosis of the aneurysm. Larger studies are needed to determine whether more frequent follow-up DSAs after FD placement are necessary and whether all patients exhibiting delayed post-treatment residual flow into an aneurysm require additional FD placement or if watchful waiting is a more suitable course.

Brain Trauma Foundation (BTF) guidelines reflect evidence-based best practices in management of traumatic brain injury. The aim of this study was to examine self-reported physician compliance and predictors of compliance related to BTF guidelines. ⋯ Few respondents reported their institutions "always" follow BTF guidelines. General surgeons and providers at high-volume level I trauma centers were more likely to comply with guidelines. Differences in survey responses based on provider and institutional characteristics may help target educational efforts.

To analyze the correlation between the K-line-based classification of patients with ossification of the posterior longitudinal ligament (OPLL) and their outcome after anterior controllable antedisplacement and fusion (ACAF) surgery. ⋯ This study shows that K-line can predict the clinical outcome of ACAF surgery for multisegmental OPLL in a different way from posterior decompression surgery. When the OPLL was thin, the outcome was satisfactory and there was no correlation with K-line-based classification of patients with OPLL. When the OPLL was >6 mm thick, the K-line (-) group patients had a better outcome than did K-line (+) group patients.
