Meta-review on Perforation Model of Subarachnoid Hemorrhage in Mice: Filament Material as a Possible Moderator of Mortality
AbstractRobust preclinical models are inevitable for researchers to unravel pathomechanisms of subarachnoidal hemorrhage (SAH). For the mouse perforation model of SAH, the goal of this meta-review was the determination of variances in mortality, SAH severity grade, and vasospasm, and their experimental moderators, as many researchers are facing with incomparable results. We searched on the databasesPubMed,Embase, andWeb of Science for articles describing in vivo experiments using the SAH perforation mouse model and measuring mortality, SAH grade, and/or vasospasm. After screening, 42 articles (total of 1964 mice) were incl...

Impact of anesthetic strategy on outcomes for patients with acute basilar artery occlusion undergoing mechanical thrombectomy
Conclusions The choice of anesthetic strategy, GA, LA, or CS, did not affect the clinical outcomes of patients with acute BAO treated with MT in the BASILAR registry.

Increased blood pressure variability during general anaesthesia is associated with worse outcomes after mechanical thrombectomy: a prospective observational cohort study
Conclusions Increased intraprocedural BPV was more likely to have poor functional outcome in patients with LVO following MT with general anaesthesia. This finding indicates that special precautions should be taken to minimise BP fluctuation during procedure.

General anesthesia but not conscious sedation improves functional outcome in patients receiving endovascular thrombectomy for acute ischemic stroke: A meta-analysis of randomized clinical trials and trial sequence analysis
ConclusionPatients with acute anterior circulation ischemic stroke receiving GA were associated with a higher successful recanalization rate as well as a better 3-month neurological outcome compared to the use of CS. Further investigations are warranted to verify our findings.Systematic review registrationwww.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022342483, identifier: CRD42022342483.

Unexplained early neurological deterioration after endovascular treatment for acute large vessel occlusion: incidence, predictors, and clinical impact: Data from ANGEL-ACT registry
Conclusions ENDunexplained associated with poor 90day outcomes occurred in 4.3% of patients with acute LVO undergoing EVT. Several independent predictors of ENDunexplained were identified in this study, which should be considered in daily practice to improve acute LVO management. Clinical trial Registration http://wwwclinicaltrialsgov NCT03370939.

Predictors of symptomatic intracranial hemorrhage after endovascular treatment for acute large vessel occlusion: data from ANGEL-ACT registry
AbstractSymptomatic intracranial hemorrhage (SICH) is a catastrophic complication of endovascular treatment (EVT) for large vessel occlusion (LVO). We aimed to investigate the incidence and predictors of SICH after EVT. Patients were selected from the ANGEL-ACT registry. We diagnosed SICH according to the Heidelberg Bleeding Classification. Logistic regression analyses were performed to determine the independent predictors of SICH. Of the 1283 patients, SICH was observed in 116 patients (9.0%). On multivariable analysis, admission National Institutes of Health Stroke Scale (NIHSS)  >  12 (odds ratio [OR] = 1.86,...

Close association between spreading depolarization and development of infarction under experimental ischemia in anesthetized male mice
In conclusion, our findings suggest that the occurrence of SD during ischemia might elicit infarct formation and/or influence infarct development.PMID:35901965 | DOI:10.1016/j.brainres.2022.148023

E-006 Carotid artery revascularization using the walrus balloon guide catheter: safety and feasibility from a US multicenter experience
ConclusionWalrus BGC for proximal flow-control is safe and effective during eCAS and tCAS. Procedural success was achieved in all cases, with favorable safety and functional outcomes on short term follow-up.Disclosures M. Salem: None. S. Kvint: None. A. Baig: None. A. Monteiro: None. G.

E-030 Feasibility and safety of mechanical thrombectomy for sole primary angular artery M3 and M4 MCA occlusions
ConclusionAngular artery occlusions often present with disabling symptoms, commonly including speech deficits and limb paresis. Our limited data suggests that mechanical thrombectomy of the angular artery is feasible and safe. As with thrombectomy in other vascular territories, and amongst other factors, patient outcome is influenced by grade of reperfusion.Disclosures A. Kuhn: None. J. Singh: None. F. Massari: None. A.

E-111 Analysis of intracerebral hemorrhage in n established mouse model
BackgroundKontos’ elucidated the theory that iron-mediated free radical production and subsequent oxidative damage was responsible for on-going cerebral degeneration within the infarct following ischemic stroke. The production of free radicals is likely tied to the generation of superoxide following reperfusion of the ischemic brain. Free radical production happens relatively soon after reperfusion but the time to oxidative damage of surrounding tissue is still unknown. It is well-established that ischemic stroke results in loss of autoregulation to cerebral tissues. Ischemic strokes have the potential to transform i...

Type of anaesthesia for acute ischaemic stroke endovascular treatment
CONCLUSIONS: In early outcomes, general anaesthesia improves target artery revascularisation compared to non-general anaesthesia with moderate-certainty evidence. General anaesthesia may improve adverse events (haemodynamic instability) compared to non-general anaesthesia with low-certainty evidence. We found no evidence of a difference in neurological impairment, stroke-related mortality, all intracranial haemorrhage and haemodynamic instability adverse events between groups with low-certainty evidence. We are uncertain whether general anaesthesia improves functional outcomes and time to revascularisation because the cert...

Ischemic Stroke Due to Heparin-induced Thrombocytopenia During Severe COVID-19 Infection
Intern Med. 2022 Jul 5. doi: 10.2169/internalmedicine.9531-22. Online ahead of print.ABSTRACTA 53-year-old woman with severe coronavirus disease 2019 (COVID-19) pneumonia was admitted and treated with intravenous unfractionated heparin for thromboprophylaxis under general anesthesia with mechanical ventilation. She developed right hemiparesis after hospitalization due to a large hemorrhagic infarction. Her platelet count decreased from 243,000/μL at administration to 121,000/μL. Anti-platelet factor 4-heparin antibody testing was positive according to a latex immunoturbidimetric assay. She was therefore diagnosed with he...
