To determine the relationship between functional connectivity (FC) using resting-state functional magnetic resonance imaging (MRI) and neurological impairment in patients with cervical spondylosis and healthy controls. ⋯ Patients with cervical spondylosis exhibiting neurological impairment experience changes in brain connectivity similar to that of patients with chronic traumatic spinal cord injury. These results suggest an increase in FC within sensorimotor regions with increasing neurological impairment and decreased connectivity between the cerebellum, putamen, and thalamus to the anterior and posterior cingulate and frontal lobe regions.

Onyx, a liquid embolic agent, is the mainstay of embolization treatment of arteriovenous malformation or arteriovenous fistula. Microcatheter retention in an embolic cast is a well-known complication. Rupture of catheter with spillage of onyx is a rare phenomenon but can lead to potential occlusion of the parent vessel. ⋯ Microcatheter rupture and spillage of onyx during embolization of arteriovenous malformation/arteriovenous fistula is a potential complication, and management should be individualized. The unique close cell design of the PED was successfully used to avoid a potentially life-threatening occlusion of the vertebrobasilar system. To the best of our knowledge, we report for the first time this novel use of PED.

Case Reports
Minor trauma in ankylosing spondylitis causing combined cervical spine fracture and oesophageal injury.
We illustrate the case of an unstable fracture of the cervical spine in ankylosing spondylitis with associated esophageal injury after minor trauma. ⋯ This case demonstrates the severity of injury after minor trauma in the context of ankylosing spondylitis, the capacity for full recovery in esophageal perforations in spinal trauma, and that clinical suspicion of such injuries allows early diagnosis, treatment, and reduced complications.

Traumatic Posterior Fossa Subdural Hemorrhage: A Multicenter, Retrospective Cohort Study.
Traumatic posterior fossa subdural hemorrhage (SDH) is a rare subtype of subdural hemorrhage in head injuries. Existing data on its pathophysiology and outcome are currently limited; therefore, the condition is not yet fully understood. The present study aimed to determine the incidence, outcome, and prognostic factors for traumatic posterior fossa SDH. ⋯ Traumatic posterior fossa SDH was extremely rare in our data set. Mortality correlated with the size of the SDH, GCS score on admission, and the presence of a skull fracture.

Clinical Usefulness of Waiting after Stent Deployment in Mechanical Thrombectomy: Effect of the Clot Integration.
Pulling a retriever stent after several minutes of waiting time is a popular technique in mechanical thrombectomy with a stent retriever, but little data exist on the actual effects of waiting after stent deployment. ⋯ Waiting after stent deployment can lead to a more successful recanalization with a smaller number of stent passages and less distal emboli. More randomized controlled trials are needed to support these findings.
