Only a few studies have investigated the gap range of motion (gROM) in cervical myelopathy or deformity caused by ossification of the posterior longitudinal ligament (OPLL). The aim of this study is to investigate the correlation between the individual gROM and the postoperative clinical outcomes of patients with OPLL. ⋯ Simultaneous circumferential decompression and fixation is an effective surgical option for patients with cervical myelopathy caused by OPLL. A higher rate of postoperative C5 palsy was observed in the patients with greater gROMs after surgery, although all patients presented with similar clinical improvements.

Surgery performed at night and on weekends is thought to be associated with increased complications. However, the impact of time of day on outcomes has not been studied within cranial neurosurgery. We aim to determine if there are differences in outcomes for cranial neurosurgery performed after hours (AH) compared with during hours (DH). ⋯ This study suggests that operating AH does not appear to negatively impact outcomes when compared with operating DH, in cases of cranial neurosurgical emergencies. Further study assessing the impact on elective neurosurgical cases is required.

We assessed the feasibility of using compressed sensing accelerated, low-velocity encoded, isotropic resolution phase contrast (CLIP) magnetic resonance angiography (MRA) for avascular trajectory planning of stereoelectroencephalography. ⋯ In the present study, CLIP-MRA provided a clear cortical vascular display noninvasively without intravascular contrast and radiation. The middle meningeal artery and diploic and emissary veins were the main conflict vessels and could be clearly displayed using CLIP-MRA but not CTA.

The albumin/fibrinogen ratio (AFR) is an independent predictor of clinical outcomes of some diseases; however, the prognostic value of AFR and the admission Hunt-Hess (HH) score is still unclear for patients with an aneurysmal subarachnoid hemorrhage (aSAH). This study aimed to assess the relationship between the AFR-HH score and 6-month outcomes of aSAH patients. ⋯ A low AFR during the perioperative period is associated with unfavorable outcomes for aSAH patients at 6 months. The combination of the AFR and admission HH scale score provides superior predictive capacity to either the AFR or HH scale score alone.

Neuroendovascular treatment via transradial access (TRA) has gained popularity as a minimally invasive technique. However, the flow reversal (FR) system, reported useful in carotid artery stenting (CAS), cannot be applied via TRA because it requires an access route of more than 8 F. Herein, we report the utility of a modified FR system applied via TRA using a sheathless 8-F balloon guide catheter and a 2.6-F balloon catheter. ⋯ This study suggests that CAS with FR using our modified system is feasible via TRA and may be an effective technique with a low rate of vascular complications.
