Abstract Background and purpose Safety and predictors of rescue therapy in patients with acute ischemic stroke due to large artery atherosclerosis still remain unclear. This study aimed to test safety of rescue therapy and evaluate predictors of it after failed mechanical thrombectomy.Methods This retrospective study enrolled consecutively 245 patients with acute ischemic stroke treated by endovascular treatment from March 2016 to April 2019 in a single stroke center. We analyzed the clinical data and laboratory test for safety and predictors of rescue therapy. Binary logistic analysis was applied to confirm the independently relationship.Results There were totally 145 patients enrolled among 245 patients. Rescue therapy was independently associated with the excellent outcome [p=0.048, adjusted OR: 2.655, 95%CI: 1.008 – 6.989] and longer procedure time of endovascular treatment [p=0.004, adjusted OR: 3.722, 95%CI: 1.519-9.122], but there was no significance on complications and mortality. Prestrike incidence [p=0.004, adjusted OR:4.427, 95%CI:1.618-12.114], use of rt-PA [p=0.003, adjusted OR:4.792, 95%CI:1.688-13.602], tandem occlusion [p=0.001, adjusted OR:0.021, 95%CI:0.002-0.194], PLT [p=0.012, adjusted OR:3.234, 95%CI:1.289-8.113], P-LCR>42.3% [p=0.031, adjusted OR:0.132, 95%CI:0.021-0.827] were independent predictors of rescue therapy.Conclusions Rescue therapy for acute ischemic stroke due to large artery atherosclerosis costs more procedure time of endovascular treatment, but it can successfully recanalize the occlusive large artery and is independently related to the excellent clinical outcome without increasing ICH, sICH, reocclusion and others. Prestroke incidence, use of rt-PA, tandem occlusion, PLT and P-LCR may be independent predictors of rescue therapy in acute ischemic stroke due to large artery atherosclerosis.

ObjectiveAsymptomatic intracranial hemorrhage (aSICH) is a common phenomenon after endovascular treatment of acute ischemic stroke, but its prognostic impacts remain unclear. This study evaluated functional outcomes of thrombectomy in patients with and without aSICH.MethodsPatients with acute ischemic stroke due to large artery occlusion in the anterior circulation who were treated with thrombectomy were enrolled in 21 centers. According to CT scans performed within 72 hours of endovascular procedures, patients with aSICH or without intracranial hemorrhage were included while patients with symptomatic intracranial hemorrhage (SICH) were excluded. Baseline data and functional outcomes were compared between patients with aSICH and those without intracranial hemorrhage. Logistic regression analysis was applied to evaluate the impacts of aSICH on functional outcomes.ResultsOf the 632 patients with endovascular treatment, 101 (16.0%) were classified as having SICH, 212 (33.5%) as having aSICH, and 319 (50.5%) as being without intracranial hemorrhage. Patients with aSICH after endovascular treatment had a lower ratio of excellent outcome (mRS 0–1, OR 0.53; 95% CI 0.33 to 0.84, P=0.007) than those without intracranial hemorrhage. There were no significant differences concerning favorable outcome (mRS 0–2, OR 0.76; 95% CI 0.50 to 1.14, P=0.185) or mortality (OR 0.64; 95% CI 0.38 to 1.09, P=0.101) between patients with aSICH and those without intracranial hemorrhage.ConclusionsIn an Asian population, aSICH after thrombectomy may decrease the likelihood of an excellent functional outcome but does not influence a favorable outcome and mortality in patients with ischemic stroke due to large artery occlusion in the anterior circulation.

Background Patients with acute ischemic stroke (AIS) caused by large vessel occlusion (LVO) were usually transferred from a primary stroke center (PSC) to a comprehensive stroke center (CSC) for endovascular treatment (drip-and-ship [DS]), while driving the doctor from a CSC to a PSC to perform a procedure is an alternative strategy (drip-and-drive [DD]). Purpose To compare the efficacy and prognosis of the two strategies. Material and Methods From February 2017 to June 2019, 62 patients with LVO received endovascular treatment via the DS and DD models and were retrospectively analyzed from the stroke alliance based on our CSC. Primary endpoint was door-to-reperfusion (DTR) time. Secondary endpoints included puncture-to-recanalization (PTR) time, modified Thrombolysis in Cerebral Infarction (mTICI) rates at the end of the procedure, and modified Rankin Scale (mRS) at 90 days. Results Forty-one patients received the DS strategy and 21 patients received the DD strategy. The DTR time was significantly longer in the DS group compared to the DD group (315.5 ± 83.8 min vs. 248.6 ± 80.0 min; P < 0.05), and PTR time was shorter (77.2 ± 35.9 min vs. 113.7 ± 69.7 min; P = 0.033) compared with the DD group. Successful recanalization (mTICI 2b/3) was achieved in 89% (36/41) of patients in the DS group and 86% (18/21) in the DD group ( P = 1.000). Favorable functional outcomes (mRS 0–2) were observed in 49% (20/41) of patients in the DS group and 71% (15/21) in the DD group at 90 days ( P = 0.089). Conclusion Compared with the DS strategy, the DD strategy showed more effective and a trend of better clinical outcomes for AIS patients with LVO.

Background and Purpose— To assess the effect of inter-hospital transfer on time to treatment and functional outcome after endovascular treatment (EVT) for acute ischemic stroke, we compared patients transferred from a primary stroke center to patients directly admitted to an intervention center in a large nationwide registry. Methods— MR CLEAN (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands) Registry is an ongoing, prospective, observational study in all centers that perform EVT in the Netherlands. We included adult patients with an acute anterior circulation stroke who received EVT between March 2014 to June 2016. Primary outcome was time from arrival at the first hospital to arterial groin puncture. Secondary outcomes included the 90-day modified Rankin Scale score and functional independence (modified Rankin Scale score of 0–2). Results— In total 821/1526 patients, (54%) were transferred from a primary stroke center. Transferred patients less often had prestroke disability (227/800 [28%] versus 255/699 [36%]; P =0.02) and more often received intravenous thrombolytics (659/819 [81%] versus 511/704 [73%]; P <0.01). Time from first presentation to groin puncture was longer for transferred patients (164 versus 104 minutes; P <0.01, adjusted delay 57 minutes [95% CI, 51–62]). Transferred patients had worse functional outcome (adjusted common OR, 0.75 [95% CI, 0.62–0.90]) and less often achieved functional independence (244/720 [34%] versus 289/681 [42%], absolute risk difference −8.5% [95% CI, −8.7 to −8.3]). Conclusions— Interhospital transfer of patients with acute ischemic stroke is associated with delay of EVT and worse outcomes in routine clinical practice, even in a country where between-center distances are short. Direct transportation of patients potentially eligible for EVT to an intervention center may improve functional outcome.

Background: Asian Americans comprise a rapidly increasing segment of the population, but little is known of their outcomes after acute ischemic stroke. We compared Asians and whites presenting to a San Francisco Bay Area tertiary/quaternary stroke center that uniquely serves a high proportion of Asian American patients, and reviewed the treatment rates and outcomes of Asian Americans presenting with acute ischemic stroke compared to whites. Methods: We performed a retrospective study of ischemic stroke patients presenting to our center between 1/2014-7/2020, conducting univariate analyses of demographics, comorbidities, and clinical outcomes in those designated as Asian compared with white patients. Odds ratios and chi-square analyses were conducted between groups. Asians were defined as those of Asian Indian, Chinese, Filipino, Japanese, Korean, or Vietnamese descent. Results: Between 1/2014 and 7/2020, 3958 patients presented with ischemic stroke; 852 (21.5%) were Asian and 2107 (53.2%) were white. Asians were older and more likely to have hypertension, hyperlipidemia, and diabetes, and less likely to have atrial fibrillation (Table 1). More Asians presented directly to our center, while more whites were transferred in. IV rt-PA rates are described in Table 1. Overall, Asians were less likely to receive endovascular treatment (Table 1). Asians had a higher NIHSS at discharge, although there was no difference in the proportion who expired or who were discharged home. Conclusions: Asians with ischemic stroke tended to have more comorbid conditions than whites. Though there was a trend towards similar IV rt-PA rates between Asians and whites presenting to the ED, Asians were less likely to receive endovascular treatment, and had worse NIHSS on discharge with similar proportion going home. This may have to do with local geographic/socioeconomic distribution, or differences in stroke etiology. Further analyses are needed to better elucidate these disparities.

Background: We report our single center experience of endovascular treatment of stroke by the technique of direct clot aspiration. Methods: From September 2013 to July 2014, from our prospectively gathered database, we reviewed 114 patients presenting with large vessels occlusion in the settings of acute ischemic stroke and treated with the ADAPT technique in first intention. Results: Hundred and fourteen patients (55 female and 54 male patients (mean age: 64 y.o) presented with a median NIHSS score of 15,9 (1-26). The localisation of arterial occlusion was the MCA in 52/114 (45%), the ICA in 16/114 (14%), a tandem occlusion in 35/114 (30,7%) and the vertebro basilar territory in 11/114 (9,65%). Procedures were performed under sedation in 66% of cases and general anesthesia in 33%. The aspiration technique alone was successful in achieving TICI 2b/3 in 48,2% of cases (55/114) with a mean of 2 passes. The additional use of stent retrievers improved the TICI 2b/3 revascularization rate to 87,5%. With aspiration alone, the average time from groin puncture to at least TICI 2b recanalization was 37 min (from clot contact to recanalisation: 17 min). Ninety day functional outcomes was available for 87/114 patients with 50% of good functional outcomes (mRS≤ 0-2) and 15% death (mRS 6). For the overal series there were 10 cases (8,7%) of procedural complications (one non occlusive dissection, 4 distal emboli, and 5 Subarachnoid hemorrhages) and 2 symptomatic intracerebral hemorrhages (2,5%). Discussion: The aspiration technique utilizing large bore aspiration catheters technique alone was effective in 48% of the cases being fast, safe and simple, but to achieve a recanalization rate of 87,5% it add to be completed by the use of stentrievers in the other cases. The relevance of this technique needs to studied in larger prospective multicentric studies.

Solitaire Fr

Background & purpose: To evaluate safety and efficacy of the Solitaire FR in the treatment of patients with acute ischemic stroke (AIS) secondary to large artery occlusion. Methods: Retrospective study of consecutive patients presenting with AIS treated with Solitaire FR as the first choice device to restore blood flow in 6 experienced European sites according to the hospitals’ stroke protocols (direct IA, bridging IV t-PA/IA and failed or contraindicated IV t-PA). Sites provided patient information at pre-procedure, procedure, 24hrs, discharge and 90 days. An independent Core Lab evaluated TICI scores on the pre-procedure and post-procedure angiograms. Recanalization was defined as TICI 2 or 3 post Solitaire FR device use and prior to any rescue therapy. Baseline and post-treatment brain CT or MRI were also centrally reviewed for symptomatic ICH classification (PH2 + death or neurologic deterioration). Good early neurological outcome was defined as NIHSS score improvement of ≥10 points or NIHSS 0,1 at discharge, and favourable functional outcome as modified Rankin Scale (mRS) score ≤ 2 at day 90. Patients with missing mRS data were judged to have worst possible outcome for data analysis. Results: Of the 206 patients treated with Solitaire FR, the device was used as first line treatment in 141 patients (mean age, 66; median NIHSS, 18): 74 patients were treated with IV t-PA prior to endovascular treatment, 56 had contra indication to IV t-PA and 11 were directly treated IA. Safety and efficacy results in the overall and IV t-PA treated patients are shown in the table . The mean number of recoveries was 1.8 and median time from groin puncture to successful revascularization was 45 minutes. Conclusions: This retrospective, uncontrolled study shows that Solitaire FR is safe and achieves good revascularization rates and functional outcomes in patients with AIS and large artery occlusion.

Background Intracranial artery atherosclerotic stenosis (ICAS) is among the causes of intracranial large artery occlusion (LVO). The optimal treatment strategy for patients with ischemic stroke due to ICAS-related LVO remains unclear. In this retrospective case series, we discussed our experience with direct angioplasty as frontline therapy for ICAS-related LVO. Methods We extracted data for patients who had a known pre-existing ICAS and undergone direct angioplasty as frontline therapy for ICAS-related LVO in the anterior circulation at our institution between January 2019 and December 2019. We analysed procedural details, the degree of reperfusion, functional outcomes, and complications. Successful reperfusion was defined as a modified Treatment in Cerebral Ischemia (mTICI) score of 2 b − 3. Functional outcomes at 90 days were assessed using modified Rankin Scale (mRS) scores (good outcome: mRS of 0–2). Results We analysed data for five patients (mean age: 51.6 ± 11 years). The mean time from symptom onset to recanalization was 371 ± 38.6 min. Occlusions involved the first segment of the middle cerebral artery in four patients and the intracranial internal carotid artery in one patient. Successful reperfusion was achieved in four (80%) patients. The remaining patient (20%) underwent intracranial stenting as rescue therapy, achieving a final mTICI of 2a. No re-occlusion was observed on follow-up images. Four patients (80%) achieved good outcomes at 90 days. There were no cases of symptomatic intracranial hemorrhage, although asymptomatic intracranial haemorrhage was observed in one patient. Conclusion Direct angioplasty may represent an alternative treatment strategy in patients with acute ischemic stroke due to known ICAS-related LVO.
