Immediate postinterventional flat-panel CT: Differentiation of hemorrhagic transformation from contrast exudation of acute ischemic stroke patients after thrombectomy
CONCLUSION: The hyperdensity on immediately post-thrombectomy flat-panel CT could differentiate HT from contrast exudation with an excellent negative predictive value. The ability of flat-panel CT in differentiating HT from contrast exudation was improved when combined with HUavg and mass effect.PMID:36036263 | DOI:10.1177/02841851221122429

P08 Detection of cerebral aneurysms in unenhanced CT images of patients with subarachnoid hemorrhage using the sparing aneurysm sign (SAS)
ConclusionsThe aneurysm location and size can be determined in unenhanced CT images in many cases using the new SAS (sparing aneurysm sign). Whereas quantitative measurements of HU can support the aneurysm detection.ReferencesConnolly ES, Rabinstein AA, Carhuapoma JR, et al.

P65 "Direct Transfer to Angio Suite" (DTAS) enabling via utilization of Philips advanced 3D neuro-imaging prototype technology
Conclusions3D neuro-imaging prototype technology has provided an almost multi-detector CT level of anatomical structures spatial and contrast resolution, during pre-procedural ASPECT assessment, clot localization, collaterals and post-procedural hemorrhagic components evaluation during DTAS for mechanical thrombectomy, significantly reducing the door-to-puncture timing. This new technology significantly improves and maximizes the triaging of these LVO patients in the DTAS pathway.ReferencesPatrick Nicholson, Nicole M Cancelliere, John Bracken, et al.

Non-contrast head CT alone for thrombectomy in acute ischemic stroke: analysis of the ANGEL-ACT registry
Conclusions In patients selected for MT using NCHCT alone versus NCHCT + NVI, there were improved procedural outcomes and smaller increases in baseline mRS scores at 90 days.

A Novel Dual-Energy CT Method for Detection and Differentiation of Intracerebral Hemorrhage From Contrast Extravasation in Stroke Patients After Endovascular Thrombectomy
ConclusionTwinSpiral DECT demonstrates high accuracy and excellent specificity for differentiating ICH from CS in patients after mechanical thrombectomy due to acute ischemic stroke, and improves inter-reader agreement for detecting ICH compared to the standard mixed images.

Vitamin D level is associated with rupture of intracranial aneurysm in patients with subarachnoid hemorrhage
ConclusionVitamin D level is associated with rupture of intracranial aneurysm in patients with SAH. Patients with aneurysmal SAH have lower vitamin D levels than those with non-aneurysmal SAH.

Post-ASPECTS based on hyperdensity in NCCT immediately after thrombectomy is an ultra-early predictor of hemorrhagic transformation and prognosis
ConclusionPost-ASPECTS predicted 90-day prognosis, death, and HT with high specificity and high positive predictive value in patients with AIS with ACLVO. Post-ASPECTS may be an ultra-early predictor of prognosis after thrombectomy.

ASPECT Score and Its Application to Vasospasm in Aneurysmal Subarachnoid Haemorrhage: a Case –Control Study
AbstractDelayed cerebral ischaemia (DCI) is a significant complication of aneurysmal subarachnoid haemorrhage (aSAH) and is strongly associated with poorer outcome. The Alberta Stroke Program Early Computer Tomography (ASPECT) score is an established scoring tool, used in acute ischaemic stroke, to quantify early ischaemic changes on CT head scans. We aim to identify if ASPECT scoring correlates with functional outcome in DCI following aSAH. Retrospective case –control study. Inclusion criteria: admission to the Department of Neurosurgery at Leeds Teaching Hospitals NHS Trust (a tertiary neurosurgical centre in the Unite...

Risk factors for infarct growth and haemorrhagic or oedematous complications after endovascular treatment - a literature review
CONCLUSIONS: The identification of factors that affect post-MT ischaemic area evolution may result in studies assessing the effects of their modification, and potentially improve clinical outcomes. Modifiable parameters, including periprocedural systemic blood pressure and some biochemical factors, may be of particular importance.PMID:35929520 | DOI:10.5603/PJNNS.a2022.0056
