Outcome of endovascular treatment in acute basilar artery occlusion with National Institutes of Health Stroke Scale score 10-19.
Authors of this study aimed to investigate the efficacy and safety of endovascular treatment (EVT) versus standard medical treatment (SMT) alone in patients with acute basilar artery occlusion (BAO) and moderate deficit (National Institutes of Health Stroke Scale [NIHSS] score 10-19). ⋯ EVT leads to improved outcomes compared to those with SMT alone. Younger age, absence of diabetes mellitus, higher baseline pc-ASPECTSs, and mTICI score of 2b-3 were associated with better functional outcome in the EVT group.

Transradial versus transfemoral access for embolization of intracranial aneurysms with the Woven EndoBridge device: a propensity score-matched study.
Transradial access (TRA) is commonly utilized in neurointerventional procedures. This study compared the technical and clinical outcomes of the use of TRA versus those of transfemoral access (TFA) for intracranial aneurysm embolization with the Woven EndoBridge (WEB) device. ⋯ TRA has comparable outcomes, with shorter procedure and fluoroscopy time, to TFA for aneurysm embolization with the WEB device.

Morphometric comparison of Fisch type A and endoscopic endonasal far-medial supracondylar approaches to the jugular foramen.
The jugular foramen (JF) is one of the most complex and challenging skull base regions to approach surgically. The extreme medial approach to access the JF provides the approach angle from an anterior direction and does not require dissection and sacrifice of the jugular bulb (JB) to reach the pars nervosa. The authors compared the Fisch type A approach to the extreme medial approach to access the JF and evaluated the usefulness of the extreme medial approach. ⋯ The surgical maneuverability of the extreme medial approach was not inferior to that of the Fisch type A approach. The extreme medial approach can provide excellent surgical field visualization, while preserving the JB. Select cases of chordomas, chondrosarcomas, and JF schwannomas should be considered for an extreme medial approach. These two approaches are complementary, and a case-by-case detailed analysis should be conducted to decide the best approach.

Long-term efficacy of vestibular neurotomy in disabling Ménière's disease and Tumarkin drop attacks.
When Ménière's disease (MD) becomes disabling due to the frequency of attacks or the appearance of drop attacks (i.e., Tumarkin otolithic crisis) despite "conservative" medical and surgical treatments, a radical treatment like vestibular neurotomy (VN) is possible. An ideal MD treatment would relieve symptoms immediately and persist after the therapy. The aim of this study was to identify if VN was effective after 10 years of follow-up regarding vertigo and drop attacks, and to collect the immediate complications. ⋯ In case of disabling MD (disabling vertigo refractory to conservative vestibular treatments-Tumarkin drop attacks), VN via the retrosigmoid approach must be the prioritized proposal in comparison to intratympanic gentamicin injections, because of the extremely low complication rate and the immediate and long-lasting effect of this treatment on vertigo and falls.

Visualization of cortical activation in human brain by flavoprotein fluorescence imaging.
To develop an innovative brain mapping and neuromonitoring method during neurosurgery, the authors set out to establish intraoperative flavoprotein fluorescence imaging (iFFI) to directly visualize cortical activations in human brain. The significance of iFFI was analyzed by comparison with intraoperative perfusion-dependent imaging (iPDI), which is considered the conventional optical imaging, and by performing animal experiments. ⋯ This is the first report in humans of successful intraoperative visualization of cortical activations by using iFFI, which showed rapid evoked cortical activity prior to perfusion-dependent signal changes. Further technical improvements can lead to establishment of iFFI as a real-time intraoperative tool.
