Conclusion: In acute LAO patients, the presence of SMCV– was a sensitive and specific imaging marker for midline shift. SMCV– had supplementary value to baseline ischemic core volume in predicting midline shift.]]> Wed 05 Oct 2022 15:04:56 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52638 Thu 19 Oct 2023 15:12:05 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:19818 Sat 24 Mar 2018 07:56:57 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47319 70mL. We aimed to compare outcomes of EVT and non-EVT patients with an ischemic core≥70mL, hypothesizing that there would be a benefit from EVT for fair outcome (three-month modified Rankin Scale, mRS, 0-3) after stroke. METHODS: Retrospective analysis of patients enrolled into a multi-center (Australia, China and Canada) registry (2012-2020) who underwent CTP within 24 hours of stroke onset and had a baseline ischemic core≥70mL. Primary outcome was the estimation of the association of EVT in patients with core volume ≥70mL, as well as within 70-100mL and ≥100mL subgroups with fair outcome. RESULTS: Of the 3283 patients in the registry, 299 had CTP core≥70 mL and 269 complete data (135 had core volume between 70-100mL and 134≥100mL). EVT was performed in 121(45%) patients. EVT-treated patients were younger (median 69 versus 75 years; p=0.011), had lower pre-stroke mRS, and smaller median core volumes, 92[79-116.5]mL versus 105.5[85.75-138]mL, (p=0.004). EVT-treated patients had higher odds of achieving fair outcome in adjusted analysis (30% versus 13.9% in the non-EVT group; aOR 2.1(95% CI 1, 4.2), p=0.038). The benefit was seen predominantly in those with 70-100mL core (71 /135 (52.6%) EVT-treated), with 54.3% in EVT-treated versus 21% in non-EVT group achieving a fair outcome (aOR 2.5 (95% CI 1, 6.2), p=0.005). Of those with a core≥100mL, 50 /134(37.3%) underwent EVT. Proportions of fair outcome were very low in both groups (8.1% versus 8.7%; p=0.908). DISCUSSION: We found a positive association of EVT with 3-month outcome after stroke in patients with a baseline CTP ischemic core volume 70-100 mL but not in those with ≥100 mL. Randomized data to confirm these findings is required. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that EVT is associated with better motor outcomes 3 months following CTP-defined ischemic stroke with core of 70-100 mL.]]> Fri 13 Jan 2023 11:06:45 AEDT ]]>
