Objective: To objectively assess the accuracy of 320-row multidetector computed tomographic (CT) angiography to diagnose cerebral vasospasm after a subarachnoid hemorrhage using a new quantitative method.
Methods: Fifty-four arterial segments were measured in 8 patients who had subarachnoid hemorrhage and underwent digital subtraction angiography within 24 hours after CT angiography for clinical suspicion of cerebral vasospasm.
Results: A correlation between arterial diameters measurements made on CT angiography and digital subtraction angiography was observed. The degree of vasospasm tended to be overestimated in the anterior circulation, with arterial diameters that were between 0.05 and 0.72 mm smaller than those on digital subtraction angiography.
Conclusions: A quantitative approach can be used to objectively evaluate the ability of multidetector CT angiography to assess arterial diameter in patients with clinical symptoms of postsubarachnoid hemorrhage cerebral vasospasm. This pilot study also suggests that CT angiography may overestimate the degree of cerebral vasospasm in the anterior circulation.

First out-of-bed mobilisation in adults with severe acquired brain injury in Scandinavian neurointensive care units: A survey of current clinical practice (FOOBScan).

Department of Brain and Spinal Cord Injury, Neuroscience Centre, Copenhagen University Hospital - Rigshospitalet, Copenhagen, Denmark.
Background: The harm-benefit balance for early out-of-bed mobilisation of patients with severe acquired brain injury (ABI) in neurointensive care units (neuro-ICUs) is unclear, and there are no clinical guidelines. This study aimed to survey the current clinical practice and perceptions among clinicians involved in first out-of-bed mobilisation in Scandinavian neuro-ICUs.
Methods: This was a cross-sectional, anonymous, web-based survey; the reporting follows the recommended CROSS checklist.
The effect of transcutaneous auricular vagus nerve stimulation on cardiovascular function in subarachnoid hemorrhage patients: A randomized trial.

Department of Neurosurgery, Washington University School of Medicine, Springfield, United States.
Background: Subarachnoid hemorrhage (SAH) is characterized by intense central inflammation, leading to substantial post-hemorrhagic complications such as vasospasm and delayed cerebral ischemia. Given the anti-inflammatory effect of transcutaneous auricular vagus nerve stimulation (taVNS) and its ability to promote brain plasticity, taVNS has emerged as a promising therapeutic option for SAH patients. However, the effects of taVNS on cardiovascular dynamics in critically ill patients, like those with SAH, have not yet been investigated.

Background And Objectives: Reversible cerebral vasoconstriction syndrome (RCVS) is a rare cause of stroke characterized by headache, seizures, focal deficits, or encephalopathy. Very little is known about this rare condition from the Indian subcontinent. Here, we present the clinical and imaging characteristics and short-term outcomes of RCVS patients from South India.

Background: This study aimed to analyze the incidence of delayed cerebral ischemia (DCI) and outcome stratified by age in patients who suffered aneurysmal subarachnoid hemorrhage.
Methods: A cohort study with patients from Christ the Redeemer Hospital from 2014 to 2020, with 359 patients separated into 2 groups, 48 of them aged under 40 years and 311 aged 40 years or over.
Results: In patients under 40 years of age, DCI was found in 81.

: Subarachnoid hemorrhage (SAH) is a life-threatening cerebrovascular condition that triggers a robust inflammatory response and cerebral vasospasm. This study aimed to evaluate the effects of anakinra, an interleukin-1 receptor antagonist, and tocilizumab, an interleukin-6 receptor antagonist, on inflammation and vasospasm in an experimental rat SAH model. : Forty male Sprague Dawley rats (200-250 g) were randomly assigned to five groups: control, SAH, SAH + anakinra (ANA), SAH + tocilizumab (TCZ), and SAH + anakinra + tocilizumab (ANA+TCZ).
