OBJECTIVEMechanical thrombectomy using a Solitaire stent retriever has been widely applied as a safe and effective method in adult acute ischemic stroke (AIS). However, due to the lack of data, the safety and effectiveness of mechanical thrombectomy using a Solitaire stent in pediatric AIS has not yet been verified. The purpose of this study was to explore the safety and effectiveness of mechanical thrombectomy using a Solitaire stent retriever for pediatric AIS.METHODSBetween January 2012 and December 2017, 7 cases of pediatric AIS were treated via mechanical thrombectomy using a Solitaire stent retriever. The clinical practice, imaging, and follow-up results were reviewed, and the data were summarized and analyzed.RESULTSThe ages of the 7 patients ranged from 7 to 14 years with an average age of 11.1 years. The preoperative National Institutes of Health Stroke Scale (NIHSS) scores ranged from 9 to 22 with an average of 15.4 points. A Solitaire stent retriever was used in all patients, averaging 1.7 applications of thrombectomy and combined balloon dilation in 2 cases. Grade 3 on the modified Thrombolysis In Cerebral Infarction scale of recanalization was achieved in 5 cases and grade 2b in 2 cases. Six patients improved and 1 patient died after thrombectomy. The average NIHSS score of the 6 cases was 3.67 at discharge. The average modified Rankin Scale score was 1 at the 3-month follow-up. Subarachnoid hemorrhage after thrombectomy occurred in 1 case and that patient died 3 days postoperatively.CONCLUSIONSThis study shows that mechanical thrombectomy using a Solitaire stent retriever has a high recanalization rate and excellent clinical prognosis in pediatric AIS. The safety of mechanical thrombectomy in pediatric AIS requires more clinical trials for confirmation.

Background: Mechanical thrombectomy is the standard therapy in patients with acute ischemic stroke (AIS). The primary aim of our study was to compare the procedural efficacy of the direct aspiration technique, using Penumbra ACETM aspiration catheter, and the stent retriever technique, with a SolitaireTM FR stent. Secondarily, we investigated treatment-dependent and treatment-independent factors that predict a good clinical outcome. Methods: We analyzed our series of mechanical thrombectomies using a SolitaireTM FR stent and a Penumbra ACETM catheter. The clinical and radiographic data of 76 patients were retrospectively reviewed. Using binary logistic regression, we looked for the predictors of a good clinical outcome. Results: In the Penumbra ACETM group we achieved significantly higher rates of complete vessel recanalization with lower device passage counts, shorter recanalization times, shorter procedure times and shorter fluoroscopy times (p < 0.001) compared to the SolitaireTM FR group. We observed no significant difference in good clinical outcomes (52.4% vs. 56.4%, p = 0.756). Predictors of a good clinical outcome were lower initial NIHSS scores, pial arterial collateralization on admission head CT angiography scan, shorter recanalization times and device passage counts. Conclusions: The aspiration technique using Penumbra ACETM catheter is comparable to the stent retriever technique with SolitaireTM FR regarding clinical outcomes.

OBJECTIVE Mechanical thrombectomy is standard of care for the treatment of acute ischemic stroke. However, limited data are available from assessment of outcomes of FDA-approved devices. The objective of this study is to compare clinical outcomes, efficacy, and safety of non–stent retriever and stent retriever thrombectomy devices. METHODS Between January 2008 and June 2014, 166 patients treated at Jefferson Hospital for Neuroscience for acute ischemic stroke with mechanical thrombectomy using Merci, Penumbra, Solitaire, or Trevo devices were retrospectively reviewed. Primary outcomes included 90-day modified Rankin Scale (mRS) score, recanalization rate (thrombolysis in cerebral infarction [TICI score]), and incidence of symptomatic intracranial hemorrhages (ICHs). Univariate analysis and multivariate logistic regression determined predictors of mRS Score 3–6, mortality, and TICI Score 3. RESULTS A total of 99 patients were treated with non–stent retriever devices (Merci and Penumbra) and 67 with stent retrievers (Solitaire and Trevo). Stent retrievers yielded lower 90-day NIH Stroke Scale scores and higher rates of 90-day mRS scores ≤ 2 (22.54% [non–stent retriever] vs 61.67% [stent retriever]; p < 0.001), TICI Score 2b–3 recanalization rates (79.80% [non–stent retriever] vs 97.01% [stent retriever]; p < 0.001), percentage of parenchyma salvaged, and discharge rates to home/rehabilitation. The overall incidence of ICH was also significantly lower (40.40% [non–stent retriever] vs 13.43% [stent retriever]; p = 0.002), with a trend toward lower 90-day mortality. Use of non–stent retriever devices was an independent predictor of mRS Scores 3–6 (p = 0.002), while use of stent retrievers was an independent predictor of TICI Score 3 (p < 0.001). CONCLUSIONS Stent retriever mechanical thrombectomy devices achieve higher recanalization rates than non–stent retriever devices in acute ischemic stroke with improved clinical and radiographic outcomes and safety.

Introduction: Mechanical thrombectomy has become the cornerstone and standard of care for acute stroke patients. Early reperfusion in patients experiencing acute ischemic stroke is the most important factor. The motivation behind this investigation is to display the aftereffects of mechanical thrombectomy in patients with large vessel occlusion in anterior and posterior circulation and to demonstrate that it lessens the level of handicap 3 months post stroke. Methods: A retrospective analysis was conducted of patients who presented with acute ischemic stroke at our center from 2015 to 2018 and received mechanical thrombectomy using combined manual aspiration with a stent retriever and with large bore catheters without the bridging technique. Result factors including recanalization rate and modified Rankin Scale at 90 days post procedure were assessed. An aggregate of 30 patients were included. Results: About 30 patients presented at the institute and met the inclusion criteria for the study. Successful recanalization (the Thrombolysis in Cerebral Infarction Score [TICI 2B]) was accomplished in 90% of patients, TICI 3 score was accomplished in 56% of the patients. 67% of the patients had good modified Rankin Scale score 0-2 result at 90 days. There were 3 symptomatic hemorrhages and 3 procedure and comorbidity-related deaths (10%). Conclusion: Mechanical thrombectomy using combined manual aspiration with a stent retriever and with large bore catheters alone without the bridging technique is an effective and safe procedure for endovascular revascularization of large vessel occlusion presenting with acute ischemic stroke.

Abstract INTRODUCTION Current randomized trials demonstrating superiority of mechanical thrombectomy for the treatment of acute ischemic stroke for anterior circulation large vessel occlusion, have enrolled patients with symptom onset up to 6 hours. Outcomes of thrombectomy beyond 6 hours have not been well studied. The Trevo Registry is designed to assess real world outcomes of the Trevo Retriever in patients experiencing acute ischemic stroke. Trevo registry has currently enrolled 1431 patients with 90-day outcome data. Outcomes of patients treated beyond 6 hours of symptom onset were studied. METHODS The study design is a prospective, open-label, consecutive enrollment, multi-center, global registry of all patients who undergo mechanical thrombectomy for acute stroke using the Trevo stent retriever as the initial device. Enrollment is expected to reach 2000 subjects at up to 100 sites. Subgroup analysis of enrolled patients treated beyond 6 hours of symptom onset and with 90-day follow-up was performed. RESULTS >As of March 24, 2017, a total of 1846 total patients were enrolled. Median NIHSS at admission was 15.5 (IQR 11–20). The majority of patients (67.4%) were treated at 6 hours or less from last known normal with a median procedure time of 50 minutes (8-286 minutes). In patients treated after 6 hours from time last known well, the revascularization rate was 93.7% with symptomatic ICH of 1.8% and 90-day mRS = 2 was 51.8%. Subgroup analysis of patients presenting within 6 hours and those presenting beyond 6 hours showed no significant difference in patient demographics or medical comorbidities. There was no difference in complication rate or 90-day outcome between the two groups. CONCLUSION The Trevo Retriever Registry represents the first look at real world data with stent retriever use in the era of clinical trials showing the overwhelming benefit of stent retrievers to treat acute ischemic stroke. This data represents real world use of the Trevo Retriever including those treated beyond 6 hours after stroke symptoms (33.8%), and this data adds to the results from recent trials with restricted eligibility criteria.

Aim. Mechanical thrombectomy is standard of care for the treatment of acute ischemic stroke. The objective of this study is to analyze the results of our own experience of endovascular treatment in Federal State Budgetary Institution “Research Institute for Complex Issues of Cardiovascular Diseases” Kemerovo.Methods. 12 patients with AIS and underwent mechanical thrombectomy with «Trevo» stent-retriever were included in this analysis. Primary outcomes included 90-day modified Rankin scale (mRS) score, first pass effect (FPE) and recanalization rate (TICI score), the combined incidence of postintervention hemorrhages and mortality at 90 days.Results. Among 12 patients (66.7% male, age 59.5 [57.5; 66.5] years) hypertension were in 100%, 61.5% had an ischemic heart disease, 53.8% was current smoking and atrial fibrillation. Median of the NIHSS scale was 13 points, mRS≥4 was in 75% of patients. In 33.3% was a tandem lesion (internal carotid artery terminus and middle cerebral artery) and 25% required stenting of the carotid artery. Good clinical outcomes (mRS≤2 at 90 days) were achieved in 77.8% (7/9) among surviving patients. The 90-day NIHSS score – 4 [1; 5]. The first pass effect and recanalization rate (TICI Scores 2b-3/3) was achieved in 50% and 91.7% of patients. The combined incidence of postintervention hemorrhages and mortality at 90 days was 33.3% and 25% respectively.Conclusion. Despite the small sample size, stent retriever mechanical thrombectomy in AIS provides satisfactory clinical results.

BackgroundRecent randomized clinical trials (RCTs) demonstrated the efficacy of mechanical thrombectomy using stent-retrievers in patients with acute ischemic stroke (AIS) with large vessel occlusions; however, it remains unclear if these results translate to a real-world setting. The TREVO Stent-Retriever Acute Stroke (TRACK) multicenter Registry aimed to evaluate the use of the Trevo device in everyday clinical practice.MethodsTwenty-three centers enrolled consecutive AIS patients treated from March 2013 through August 2015 with the Trevo device. The primary outcome was defined as achieving a Thrombolysis in Cerebral Infarction (TICI) score of ≥2b. Secondary outcomes included 90-day modified Rankin Scale (mRS), mortality, and symptomatic intracranial hemorrhage (sICH).ResultsA total of 634patients were included. Mean age was 66.1±14.8 years and mean baseline NIH Stroke Scale (NIHSS) score was 17.4±6.7; 86.7% had an anterior circulation occlusion. Mean time from symptom onset to puncture and time to revascularization were 363.1±264.5 min and 78.8±49.6 min, respectively. 80.3% achieved TICI ≥2b. 90-day mRS ≤2 was achieved in 47.9%, compared with 51.4% when restricting the analysis to the anterior circulation and within 6 hours (similar to recent AHA/ASA guidelines), and 54.3% for those who achieved complete revascularization. The 90-day mortality rate was 19.8%. Independent predictors of clinical outcome included age, baseline NIHSS, use of balloon guide catheter, revascularization, and sICH.ConclusionThe TRACK Registry results demonstrate the generalizability of the recent thrombectomy RCTs in real-world clinical practice. No differences in clinical and angiographic outcomes were shown between patients treated within the AHA/ASA guidelines and those treated outside the recommendations.
