Meta-analysis of direct endovascular thrombectomy vs bridging therapy in the management of acute ischemic stroke with large vessel occlusion. Clin Neurol Neurosurg 2024; 236:108070. [PMID: 38071760 DOI: 10.1016/j.clineuro.2023.108070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 11/21/2023] [Accepted: 11/23/2023] [Indexed: 02/04/2024]
Abstract
BACKGROUND Debates persist when using intravenous thrombolysis (IVT) before mechanical thrombectomy (MT) for acute ischemic stroke (AIS) due to large-vessel occlusion (LVO). This systematic review and meta-analysis synthesized evidence on outcomes in patients with acute ischemic stroke due to large vessel occlusion (AIS-LVO), comparing bridging therapy (BT) with MT alone. METHOD We conducted searches of PubMed, Scopus, Web of Science, and the Cochrane Central Register of Controlled Trials from inception to July 2023 to identify pertinent clinical trials and observational studies. RESULT 76 studies, involving 37,658 patients, revealed no significant difference in 90-day functional independence between DEVT and BT. However, a trend favoring BT for achieving functional independence with a modified Rankin Scale (mRS) of 0-1 was observed, having Odds ratio (OR) of 0.75 (95% CI 0.66-0.86; p < 0.001). DEVT was associated with higher postprocedural mortality (OR 1.44;95% CI 1.25-1.65; p < 0.001), but a lower risk of symptomatic intracranial hemorrhage compared to BT (OR 0.855; 95% CI 0.621-1.177; p = 0.327). Successful recanalization rates favored BT, emphasizing the importance of individualized treatment decisions (OR 0.759; 95% CI 0.594-0.969; p = 0.027). Sensitivity analyses were conducted to identify key contributors to heterogeneity. CONCLUSION Our meta-analysis underscores the intricate equilibrium between functional efficacy and safety in the evaluation of DEVT and BT for ACS-LVO. Fundamentally, while BT appears more efficacious, concerns about safety arise due to the superior safety profile demonstrated by DEVT. Individualized treatment decisions are imperative, and further trials are warranted to enhance precision in clinical guidance.

Front Neurol 2023; 14:1215349. [PMID: 37928145 PMCID: PMC10621039 DOI: 10.3389/fneur.2023.1215349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 09/29/2023] [Indexed: 11/07/2023] Open
Abstract
Background In acute ischemic stroke (AIS), successful endovascular thrombectomy (EVT) of large vessel occlusion (LVO) necessitates the most suited device. Solitaire-X has longer and larger diameter pusher wires than Solitaire-FR.As the role of a larger pusher-wire diameter is uncertain, we aim to compare procedural, clinical, and radiological outcomes for AIS patients undergoing EVT using either type of Solitaire device. Procedures were performed using the Solumbra technique, which combines a large-bore aspiration catheter with a stentriever. The primary outcome was to compare rates of successful first-pass recanalization (defined as TICI 2b/3 score). The secondary objectives were procedural (rates of successful recanalization), clinical (post-procedural NIHSS and days of hospitalization), and radiological (post-procedural ASPECT score and hemorrhagic transformation) outcome measures. Design Consecutive AIS patients undergoing EVT for LVO were recruited into a prospective multicenter database at our academic center. We have used Solitaire-FR until October 2020 and Solitaire-X ever since. We retrospectively analyzed our prospective consecutive registry. Included in our analysis are patients undergoing EVT using Solitaire only; patients with tandem lesions or underlying stenosis requiring emergent stenting during the procedure were excluded. The cohort of patients treated with Solitaire-X was compared with a cohort consisting of the most recent consecutive cases undergoing EVT with the Solitaire-FR. Results A total of 182 (71.9 ± 14, 61% male patients) AIS patients were included in the analysis with both groups (n = 91 each) sharing similar demographic characteristics, premorbid conditions, and stroke characteristics (time from symptom-onset, NIHSS, ASPECTS, occlusion site, and rates of intravenous-tPA treatment). The Solitaire-X group had a higher rate of first-pass recanalization (65.9% vs. 50.5%, p = 0.049). On 24-h post-procedural head-CT, the Solitaire-X group had higher ASPECT scores (6.51 ± 2.9 vs. 5.49 ± 3.4, p = 0.042) and lower post-procedural average bleeding volumes (0.67 ± 2.1 vs. 1.20 ± 3.4 mL, p = 0.041). The Solitaire-X group had shorter duration of hospitalization (16.6 ± 13.1 days vs. 25.1 ± 23.2, p = 0.033). On multivariate analysis, using Solitaire-X was the sole independent predictor of first-pass recanalization (OR 2.17, 95% CI 1.12-4.26, p = 0.023). Conclusion In our study, the use of the Stentriever-X with a larger pusher-wire diameter was associated with a higher likelihood of first-pass effect and improved procedural, clinical, and radiological outcomes in AIS patients.

Abstract
Mechanical thrombectomy is the gold-standard treatment for patients that have suffered large-vessel occlusion (LVO) stroke. Various different stent-retrievers, aspiration catheters, and techniques have been developed to perform this procedure. We present our initial results regarding the Stream device. MATERIALS AND METHODS We performed a retrospective review of a prospectively maintained database at our high-volume centre to identify all patients treated with the Stream device between February 2021 and January 2023. We recorded baseline demographics, NIHSS, ASPECT scores, eTICI scores, complications, and 90-day mRS. RESULTS We identified 51 patients, 49.0% of whom were male (n = 25), with a median age of 73 (range: 51-89) and a median NIHSS score of 17 (range 4-22), and 68.6% received IV tPA. The median ASPECT score was 10 (range 6-10). Hyperdense clots were seen in 34 cases (66.7%), with a mean clot length of 12 ± 6.2 mm (range 2-26 mm). Clots were located in the anterior circulation in 49 patients. The standard Stream device was used in 78.4% of cases, with Stream 17 being used in 19.6% of cases. The FPE was observed in 25.5% of cases (n = 13), with the mFPE being seen in 31.4% of cases (n = 16). A final eTICI score of ≥2b was achieved in 90.2% of cases (n = 46), and eTICI 2c/3 was seen in 84.3% of cases (n = 43). Furthermore, 24 h CT scans showed that the median ASPECT score was 8 (range 0-10). Good functional outcomes at 90 days (mRS ≤ 2) were achieved in 21.6% of cases (n = 11). CONCLUSIONS The Stream device shows acceptable rates of FPE and mFPE compared to existing devices. Further larger studies are required alongside an understanding of the optimal technique for this device's use.

Abstract
To assess the clinical value of mechanical thrombectomy (MT) combined with intravenous thrombolysis (IVT) in acute ischemic stroke (AIS) by comparing it with the MT alone. In this study, we conducted a comprehensive meta-analysis of both observational and randomized controlled studies (RCTs) to investigate various outcomes. Our search for relevant studies was conducted between January 2011 and June 2022 in four major databases: PubMed, Embase, WOS, and Cochrane Library. We collected data on several outcomes, including functional independence (FI; defined as modified Rankin Scale score of 0 to 2), excellent outcomes (mRS 0-1), successful recanalization (SR), symptomatic intracerebral hemorrhage (sICH), any intracerebral hemorrhage (aICH), and mortality at three months or discharge. The primary efficacy outcome and safety outcome were FI and sICH, respectively, whereas excellent outcomes and SR were considered secondary efficacy outcomes. Additionally, mortality and aICH were analyzed as secondary safety outcomes. We employed the Mantel-Haenszel fixed-effects model for RCTs when I2 < 50%, otherwise the random-effects model was utilized. For observational studies and subgroup analyses, we used the random-effects model to minimize potential bias. A total of 55 eligible studies (nine RCTs and 46 observational studies) were included. For RCTs, the MT + IVT group was superior in FI (OR: 1.27, 95% CI: 1.11-1.46), excellent outcomes (OR: 1.21, 95% CI: 1.03-1.43), SR (OR: 1.23, 95% CI: 1.05-1.45), mortality (OR: 0.72, 95% CI: 0.54-0.97) in crude analyses. In adjusted analyses, the MT + IVT group reduced the risk of mortality (OR: 0.65, 95% CI: 0.49-0.88). However, the difference in FI between the MT + IVT group and the MT alone group was not significant (OR: 1.17, 95% CI: 0.99-1.38, Fig. 3a). For observational studies, the results of FI (OR: 1.34, 95% CI: 1.16-1.33), excellent outcomes (OR: 1.30, 95% CI: 1.09-1.54), SR (OR: 1.23, 95% CI: 1.05-1.44), mortality (OR: 0.70, 95% CI: 0.64-0.77) in the MT + IVT group were better. Additionally, the MT + IVT group increased the risk of hemorrhagic transformation (HT) including sICH (OR: 1.16, 95% CI: 1.11-1.21) and aICH (OR: 1.24, 95% CI: 1.05-1.46) in crude analyses. In adjusted analyses, significant better outcomes were seen in the MT + IVT group on FI (OR: 1.36, 95% CI: 1.21-1.52), excellent outcomes (OR: 1.49, 95% CI: 1.26-1.75), and mortality (OR: 0.73, 95% CI: 0.56-0.94). The MT + IVT therapy did improve the prognosis for AIS patients and did not increase the risk of HT compared with MT alone therapy.

Abstract
MATERIALS AND METHODS We performed a retrospective review of our prospectively maintained database to identify all patients treated with the Embotrap 3 stent-retriever between January 2021 and January 2022. We recorded the baseline demographics, NIHSS, ASPECT score and clot characteristics, first pass and final eTICI scores, complications and 90 day mRS. RESULTS One hundred and ten patients met the inclusion criteria, average age 69 ± 14 years, 50% were male (n = 55). The median NIHSS at presentation was 18 (range 3-30) and 58.2% received IV tPA prior to MT. The median ASPECT score on plain CT was 8 with average clot length 20.2 ± 14.8 mm (n = 93). The first pass effect (FPE) was seen in 41.8% of cases with modified FPE seen in 59.1%. A 24-hour CT scan (n = 97) showed median ASPECTs of 7. 43.8% of patients achieve mRS ≤ 2 at 90-day mRS (n = 64). CONCLUSION The Embotrap 3 stent-retriever has a high rate of FPE and final recanalization in this real world cohort of patients.

Abstract
BACKGROUND AND PURPOSE For patients with large-vessel occlusion, mechanical thrombectomy (MT) without IV-tPA is a proved strategy. The relative benefit of direct MT versus MT+IV-tPA for patients with indications for IV-tPA is being actively investigated. We used a national inpatient database to assess trends in use and patient profiles after MT+IV-tPA versus mechanical thrombectomy alone. MATERIALS AND METHODS The National Inpatient Sample was queried between 2013 and 2018 for patients undergoing mechanical thrombectomy for acute ischemic stroke. Patients who received mechanical thrombectomy alone were compared with those who underwent MT+IV-tPA. The Cochran-Armitage test was conducted to assess the linear trend of use of mechanical thrombectomy alone among the entire cohort and between admissions involving non-White and White patients. All estimates were nationalized using discharge weights. RESULTS A total of 89,645 weighted admissions were identified pertaining to mechanical thrombectomy for acute ischemic stroke from 2013 to 2018. Of these, 59,935 (66.9%) admissions involved mechanical thrombectomy alone. There was an increase in the trend toward the use of mechanical thrombectomy alone (trend: 3.26%; P < .001) per year. Multivariable regression analysis regarding patient profiles indicated that patients who identified as Black (OR = 0.83, P = .001) or Hispanic (OR = 0.79; P < .001) were more likely to undergo mechanical thrombectomy alone compared with those who identified as White. There was no statistically significant difference in the slope between non-White and White populations receiving mechanical thrombectomy alone (trend: +0.93% in favor of non-White; P = .096). CONCLUSIONS Our results indicated that mechanical thrombectomy alone was used more frequently than MT+IV-tPA among patients with acute ischemic stroke. The disparity between those who identify as White and non-White persisted across the years, though it is closing.

Abstract
BACKGROUND The benefit of intravenous thrombolysis (IVT) before mechanical thrombectomy (MT) in patients with large vessel occlusion (LVO) stroke is uncertain. Conventional metrics of final modified thrombolysis in cerebral ischemia (mTICI) score and 90-d modified Rankin Scale may be insensitive to IVT effects on procedural complexity and duration. OBJECTIVE To study the effect of IVT prior to MT on clot survival. METHODS We performed a single-center retrospective analysis of 257 acute stroke patients with LVO undergoing MT and analyzed the effect of IVT prior to MT using a novel, pass-by-pass clot survival methodology. RESULTS The use of IVT was associated with a significantly lower number of passes to attain mTICI 2B or greater (P = .002) or mTICI 3 (P = .039) reperfusion. The number of patients who achieved mTICI 2B or greater after the first pass was significantly higher in the IVT group (P = .003). This increased rate of reperfusion persisted into subsequent passes. CONCLUSION IVT prior to MT reduces the number of thrombectomy passes required to achieve mTICI 2B or mTICI 3 reperfusion. This information should be considered as the merits of IVT prior to MT are debated.

Abstract
BACKGROUND The added value of intravenous (IV) alteplase in large vessel occlusion (LVO) stroke over and beyond endovascular treatment (EVT) is controversial. We compared the long-term costs and cost-effectiveness of a direct-to-EVT paradigm in LVO stroke patients presenting directly to the mothership hospital to concurrent EVT and IV alteplase. METHODS We used a decision model consisting of a short-run model to analyze costs and functional outcomes within 90 days after the index stroke and a long-run Markov state transition model (cycle length of 12 months) to estimate expected lifetime costs and outcomes. Outcome data were from the DIRECT-MT trial (NCT03469206). Incremental cost-effectiveness ratios and net monetary benefits were calculated and probabilistic sensitivity analysis was performed. Analysis was performed from a healthcare perspective and a societal perspective using both a minimal assumed alteplase cost of US$1 and true alteplase cost. RESULTS When assuming a minimal cost of alteplase of $1, EVT with concurrent IV alteplase resulted in incremental lifetime cost of $5664 (healthcare perspective)/$4804 (societal perspective) and a decrement of 0.25 quality-adjusted life years (QALYs) compared with EVT only, indicating dominance of the EVT only approach. Net monetary benefits were consistently higher for EVT only compared with EVT with concurrent alteplase. Probabilistic sensitivity analysis showed increased costs without an increase in QALYs for EVT and concurrent IV alteplase compared with EVT only. Results were even more in favor of EVT when the true cost of alteplase was used for analysis. CONCLUSION EVT without concurrent alteplase is the preferred strategy from a health economic standpoint.

Subarachnoid Hemorrhage in Mechanical Thrombectomy for Acute Ischemic Stroke: Analysis of the STRATIS Registry, Systematic Review, and Meta-Analysis. Front Neurol 2021; 12:663058. [PMID: 34113310 PMCID: PMC8185211 DOI: 10.3389/fneur.2021.663058] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 04/13/2021] [Indexed: 11/13/2022] Open
Abstract
Background: The indications for mechanical thrombectomy in acute ischemic stroke continue to broaden, leading neurointerventionalists to treat vessel occlusions at increasingly distal locations farther in time from stroke onset. Accessing these smaller vessels raises the concern of iatrogenic subarachnoid hemorrhage (SAH) owing to increasing complexity in device navigation and retrieval. This study aims to determine the prevalence of SAH following mechanical thrombectomy, associated predictors, and resulting functional outcomes using a multicenter registry and compare this with a systematic review and meta-analysis of the literature. Methods: Data from STRATIS (The Systematic Evaluation of Patients Treated with Neurothrombectomy Devices for Acute Ischemic Stroke) registry were analyzed dichotomized by the presence or absence of SAH after thrombectomy. Only patients with 24-h post-procedural neuroimaging were included (n = 841). Multivariable logistic regression was performed to identify significant predictors of SAH. A systematic review and random-effects meta-analysis was also conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) protocol. Results: The prevalence of post-thrombectomy SAH was 5.23% in STRATIS with 15.9% (1.84% overall) experiencing neurological decline. Distal location of vessel occlusion (OR 3.41 [95% CI: 1.75-6.63], p < 0.001) and more than 3 device passes (OR 1.34 [95% CI: 1.09-1.64], p = 0.01) were associated with a higher probability of SAH in contrast to a reduction with administration of intravenous tissue plasminogen activator (tPA) (OR 0.48 [95% CI: 0.26-0.89], p = 0.02). There was a trend toward a higher discharge NIHSS (8.3 ± 8.7 vs. 5.3 ± 6.6, p = 0.07) with a significantly reduced proportion achieving functional independence at 90 days (modified Rankin Score 0-2: 32.5% vs. 57.8%, p = 0.002) in SAH patients. Pooled analysis of 10,126 patients from 6 randomized controlled trials and 64 observational studies demonstrated a prevalence of 5.85% [95% CI: 4.51-7.34%, I 2: 85.2%]. Only location of vessel occlusion was significant for increased odds of SAH at distal sites (OR 2.89 [95% CI: 1.14, 7.35]). Conclusions: Iatrogenic SAH related to mechanical thrombectomy is more common with treatment of distally-situated occlusions and multiple device passes. While low in overall prevalence, its effect is not benign with fewer patients reaching post-procedural functional independence, particularly if symptomatic.

Abstract
IMPORTANCE Whether intravenous thrombolysis is needed in combination with mechanical thrombectomy in patients with acute large vessel occlusion stroke is unclear. OBJECTIVE To examine whether mechanical thrombectomy alone is noninferior to combined intravenous thrombolysis plus mechanical thrombectomy for favorable poststroke outcome. DESIGN, SETTING, AND PARTICIPANTS Investigator-initiated, multicenter, randomized, open-label, noninferiority clinical trial in 204 patients with acute ischemic stroke due to large vessel occlusion enrolled at 23 hospital networks in Japan from January 1, 2017, to July 31, 2019, with final follow-up on October 31, 2019. INTERVENTIONS Patients were randomly assigned to mechanical thrombectomy alone (n = 101) or combined intravenous thrombolysis (alteplase at a 0.6-mg/kg dose) plus mechanical thrombectomy (n = 103). MAIN OUTCOMES AND MEASURES The primary efficacy end point was a favorable outcome defined as a modified Rankin Scale score (range, 0 [no symptoms] to 6 [death]) of 0 to 2 at 90 days, with a noninferiority margin odds ratio of 0.74, assessed using a 1-sided significance threshold of .025 (97.5% CI). There were 7 prespecified secondary efficacy end points, including mortality by day 90. There were 4 prespecified safety end points, including any intracerebral hemorrhage and symptomatic intracerebral hemorrhage within 36 hours. RESULTS Among 204 patients (median age, 74 years; 62.7% men; median National Institutes of Health Stroke Scale score, 18), all patients completed the trial. Favorable outcome occurred in 60 patients (59.4%) in the mechanical thrombectomy alone group and 59 patients (57.3%) in the combined intravenous thrombolysis plus mechanical thrombectomy group, with no significant between-group difference (difference, 2.1% [1-sided 97.5% CI, -11.4% to ∞]; odds ratio, 1.09 [1-sided 97.5% CI, 0.63 to ∞]; P = .18 for noninferiority). Among the 7 secondary efficacy end points and 4 safety end points, 10 were not significantly different, including mortality at 90 days (8 [7.9%] vs 9 [8.7%]; difference, -0.8% [95% CI, -9.5% to 7.8%]; odds ratio, 0.90 [95% CI, 0.33 to 2.43]; P > .99). Any intracerebral hemorrhage was observed less frequently in the mechanical thrombectomy alone group than in the combined group (34 [33.7%] vs 52 [50.5%]; difference, -16.8% [95% CI, -32.1% to -1.6%]; odds ratio, 0.50 [95% CI, 0.28 to 0.88]; P = .02). Symptomatic intracerebral hemorrhage was not significantly different between groups (6 [5.9%] vs 8 [7.7%]; difference, -1.8% [95% CI, -9.7% to 6.1%]; odds ratio, 0.75 [95% CI, 0.25 to 2.24]; P = .78). CONCLUSIONS AND RELEVANCE Among patients with acute large vessel occlusion stroke, mechanical thrombectomy alone, compared with combined intravenous thrombolysis plus mechanical thrombectomy, failed to demonstrate noninferiority regarding favorable functional outcome. However, the wide confidence intervals around the effect estimate also did not allow a conclusion of inferiority. TRIAL REGISTRATION umin.ac.jp/ctr Identifier: UMIN000021488.

Abstract
Background: Previous studies have shown conflicting results about the benefits of pretreatment with intravenous thrombolysis before endovascular treatment (EVT) in patients with acute ischemic stroke (AIS) with large vessel occlusions (LVOs). This study aimed to investigate the clinical efficacy and safety of EVT alone vs. bridging therapy (BT) in patients with AIS with LVOs. Methods: A systematic review with meta-analysis of all available studies comparing clinical outcomes between BT and EVT alone was conducted by searching the National Center for Biotechnology Information/National Library of Medicine PubMed and Web of Science databases for relevant literature from database inception to October 20, 2020. Results: A total of 93 studies enrolling 45,190 patients were included in the present analysis. In both unadjusted and adjusted analyses, BT was associated with a higher likelihood of 90-day good outcome (crude odds ratio [cOR] 1.361, 95% confidence interval [CI] 1.234-1.502 and adjusted OR [aOR] 1.369, 95% CI 1.217-1.540) and successful reperfusion (cOR 1.271, 95% CI 1.149-1.406 and aOR 1.267, 95% CI 1.095-1.465) and lower odds of 90-day mortality (cOR 0.619, 95% CI 0.560-0.684 and aOR 0.718, 95% CI 0.594-0.868) than EVT alone. The two groups did not differ in the occurrence of symptomatic intracranial hemorrhage (sICH) (cOR 1.062, 95% CI 0.915-1.232 and aOR 1.20, 95% CI 0.95-1.47), 24-h early recovery (cOR 1.306, 95% CI 0.906-1.881 and aOR 1.46, 95% CI 0.46-2.19), and number of thrombectomy device passes ≤ 2 (aOR 1.466, 95% CI 0.983-2.185) after sensitivity analyses and adjustment for publication bias. Conclusions: BT provides more benefits than EVT alone in terms of clinical functional outcomes without compromising safety in AIS patients with LVOs.

Abstract
BACKGROUND We report our initial experience with the CatchView (CV) thrombectomy device in patients with acute ischemic stroke (AIS). METHODS A retrospective analysis of 53 of 284 AIS patients (mean age 66.6±14.8 years, range 37-94) treated with a CV device between January 2019 and February 2020 was performed. The baseline characteristics (gender, age, comorbidities, National Institutes of Health Stroke Scale (NIHSS) score, intravenous tissue plasminogen activator (IV-tPA) administration, and occlusion localization) of these subjects were recorded. Modified Thrombolysis in Cerebral Ischemia (mTICI) scores of 2b and 3 were considered to indicate successful recanalization, and subjects with a modified Rankin Scale score of ≤2 on day 90 was considered a good clinical outcomes. RESULTS The mean NIHSS score was 12.3±3. Successful recanalization was achieved in 45 subjects (84.90%), and the rate of good clinical outcomes on day 90 was 43.39%. The secondary distal embolus rate was 5.66%. Symptomatic hemorrhage was observed in 3.77% of the subjects, and the mortality rate was 13.2%. CONCLUSIONS Mechanical thrombectomy devices include a wide array of endovascular tools for removing clots in AIS patients. In terms of successful recanalization and good clinical outcomes on day 90, our initial experience with the CV devices was encouraging.

Abstract
Endovascular treatment of acute ischemic stroke has become the first choice of treatment in large cerebral vessel occlusions, with a very high efficacy in terms of revascularization and reducing disability of affected patients. Revolutionizing acute therapy, it induced important paradigm shifts in the concepts of time and salvageable brain. In this review we focus on the current concepts of patient selection, imaging, techniques and perspectives of endovascular stroke treatment.

Abstract
BACKGROUND AND PURPOSE Quantitating the effect of intravenous alteplase on the technical outcome of early recanalization of large vessel occlusions aids understanding. We report the prevalence of early recanalization in patients with stroke because of large vessel occlusion treated with and without intravenous alteplase and endovascular thrombectomy, and its association with clinical outcome. METHODS Patients with acute ischemic stroke with large vessel occlusion from the ESCAPE trial (Endovascular Treatment for Small Core and Anterior Circulation Proximal Occlusion With Emphasis on Minimizing CT to Recanalization Times Trial) were included in this post hoc analysis. Outcomes of interest were the prevalence of early recanalization (1) and good outcome (2), defined as modified Rankin Scale score of 0 to 2 at 90 days. RESULTS Among 147 patients who did not receive endovascular thrombectomy, early recanalization occurred in 4/30 (13.3%) patients without and 48/117 (41.0%) patients with intravenous alteplase (adjusted risk ratios, 3.2 [95% CI, 1.2-8.1]). Good outcome was achieved by 34/116 (29.3%) of patients who received intravenous alteplase versus 10/29 (34.5%) who did not receive alteplase (adjusted risk ratios, 1.0 [95% CI, 0.6-1.5) and by 20/52 (38.5%) patients with versus 24/93 (25.8%) without early recanalization (adjusted risk ratios, 1.9 [95% CI, 1.2-2.9]). CONCLUSIONS Early recanalization was confirmed as a strong predictor of good outcome in patients who did not undergo endovascular thrombectomy and was improved with intravenous alteplase, yet a majority of patients (59.0%) did not achieve early reperfusion.

Abstract
Background Effective regulation of the biological function of endothelial progenitor cells (EPCs) is of great importance in its clinical application. This study aimed to explore the effect of microRNA-126 (miR-126) on the proliferation and migration of EPCs and the possible mechanism involved. Methods EPCs was isolated and cultured in vitro, and differences in the expression of miR-126 in endothelial cells (ECs) and EPCs, respectively, were detected by quantitative real-time PCR (RT-PCR). EPCs proliferation was then observed through CCK8 and colony formation experiments. Flow cytometry was also used to observe changes in the cycle and apoptosis of EPCs, and their migration ability was detected by scratch healing and Transwell assays. RT-PCR and Western blotting were carried out to observe the expression of key mRNA molecules and proteins of the Notch pathway. Results The relative expression of miR-126 in the EPCs group were 1.91±0.21, which was significantly higher than that in the EC group (1.25±0.06, P<0.05). When si-miR-126 and si-NC were transfected into the EPCs, it was found that the proliferation ability of cells in the si-miR-126 group decreased significantly (P<0.05), the apoptotic rate of the cells transfected with si-miR-126 was significantly increased, and the cell cycle was blocked at G0/G1 phase. RT-PCR and Western blotting demonstrated that the mRNA and protein expressions of Notch 1 and HES were significantly decreased in the si-miR-126 group. Conclusions miR-126 can effectively promote the proliferation, invasion, and migration of EPCS, while inhibiting apoptosis, through the Notch1 pathway.

Abstract
BACKGROUND Despite increasing interest in endovascular therapy (EVT) for large-core strokes, little is known about the predictors of good outcome in these patients. The aim of this study was to analyze patients with large-core strokes post-EVT and to define the predictors of favorable outcome in this population. METHODS A retrospective analysis of prospectively collected data on anterior circulation strokes undergoing EVT between January 2015 and February 2018 was performed. Patients with good baseline functional status who underwent EVT for occlusion of an anterior circulation artery and achieved successful recanalization (modified Treatment in Cerebral Ischemia score ≥2b) but had large follow-up infarct volume (FIV ≥70 cm3) were included in the study. Demographic characteristics, clinical and radiologic data, treatment and postprocedural outcomes were extracted and analyzed. The primary outcome was 90-day modified Rankin Scale (mRS) score, stratified by favorable (mRS 0-3) versus unfavorable (mRS 4-6). RESULTS Of 355 patients meeting inclusion criteria, 85 (24%) had large FIV on follow-up imaging after EVT and constituted the study cohort. No patients achieved mRS score 0-2 at hospital discharge; 32% had 90-day mRS score 0-3. On multivariate logistic regression analysis, lower FIV (OR, -0.96 [0.95-0.99]; P = 0.007), male sex (OR, -1.29 [1.07-12.3]; P = 0.026), and intravenous tissue plasminogen activator use (OR, 3.6 [2.01-8.9]; P = 0.003) were independent predictors of favorable outcome. Independent predictors of mortality on multivariate analysis were higher FIV (OR, -1.01 [1.007-1.02]; P = 0.001) and female sex (OR, 4.08 [1.25-13.3]; P = 0.02). CONCLUSIONS For patients with large-core strokes (≥70 cm3) after EVT, approximately one third have favorable outcome at 90 days. Independent predictors of favorable 90-day outcomes include male sex, intravenous tissue plasminogen activator use, and lower FIV.

Abstract
Mechanical thrombectomy has been proposed to expand the treatment time window and enhance revascularization. However, it is unclear whether its use can be extended to patients with occlusions in acute aortic dissection, especially the thoracic aorta. A 55-year-old man underwent graft replacement for acute aortic dissection type A. On postoperative day 2, he developed stroke and computed tomography showed occlusion of the right middle cerebral artery. Mechanical thrombectomy was performed by transbrachial approach. Although successful recanalization was achieved, he suffered hemorrhagic stroke. Since there is no other effective treatment and the neurologic outcome with conservative management is poor, we consider mechanical thrombectomy to be a viable therapeutic option for the treatment of postoperative stroke in patients with acute aortic dissection type A. However, further study is warranted regarding the safety of this technique.

Abstract
BACKGROUND AND PURPOSE There are limited data on the association between uric acid (UA) and symptomatic intracranial haemorrhage (SICH) in patients who have undergone mechanical thrombectomy [endovascular treatment (EVT)]. In the present study, we aimed to investigate the role of serum UA level in SICH after EVT in a real-world practice. METHODS Patients were selected from the Endovascular Treatment for Acute Anterior Circulation Ischemic Stroke (ACTUAL) registry. SICH was identified using the Heidelberg Bleeding Classification. Multivariable logistic regression analysis was performed to explore the relationship between serum UA and SICH. RESULTS Among 611 enrolled patients, 90 (14.7%) were diagnosed with SICH within 72 h after EVT. Patients with SICH had a significantly higher level of serum UA (median, 341.0 vs. 302.0 μmol/L; P = 0.003) than those without SICH. Univariate logistic regression analysis indicated that patients with UA levels in the fourth quartile, compared with the first quartile, were more likely to have SICH (odds ratio, 2.846; 95% confidence intervals, 1.429-6.003; P = 0.003). The association remained significant after multivariable adjustment for potential confounders. Furthermore, the multiple-adjusted spline regression model showed an inverted U-shaped association between UA and SICH (P = 0.047 for non-linearity). CONCLUSION Our study indicated that increased serum UA level was independently associated with SICH after EVT in acute ischaemic stroke.

[PMID: 32140863 DOI: 10.1007/s00415-020-09778-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 02/25/2020] [Accepted: 02/26/2020] [Indexed: 12/16/2022]
Abstract
BACKGROUND AND PURPOSE Whether pre-intravenous thrombolysis (IVT) provides any extra benefits to mechanical thrombectomy (MT) remains controversial. We conducted a systematic review and meta-analysis to compare MT with pre-IVT (IVT + MT) and MT without pre-IVT (MT) for acute ischemic stroke of large vessel occlusion. METHODS We systematically searched PubMed, EMBASE and Cochrane Library to identify studies comparing outcomes between IVT + MT and MT from inception to Jan 24, 2019. Random effects mode was used to pool relative risk (RR) with confidence intervals (CI) to compare functional independence in terms of modified Rankin Scale (mRS) 0-2, favorable outcome (mRS 0-1) and mortality at three-months, symptomatic intracerebral hemorrhage, successful reperfusion, and complete reperfusion between the two treatments groups. RESULTS We included 30 studies enrolling 8970 patients with acute ischemic stroke of large vessel occlusion. Compared with MT, IVT + MT significantly increased the rate of 3-month functional independence (RR 1.20, 95% CI 1.12-1.30; P < 0.0001) and favorable outcome (RR 1.28; 95% CI 1.16-1.40; P < 0.0001), increased the rate of successful reperfusion (RR 1.04,95% CI 1.01-1.08; P = 0.013) and complete reperfusion (RR 1.10; 95% CI 1.01-1.19; P = 0.024), reduced the rate of mortality (RR 0.74, 95% CI 0.67-0.82; P < 0.0001), without significantly increasing the rate of symptomatic intracerebral hemorrhage (RR 0.98,95% CI 0.82-1.17; P = 0.833). The results remained stable in sensitivity analyses and adjusting for publication bias. CONCLUSIONS Pre-IVT provides extra benefits to MT on clinical and imaging outcomes without increasing symptomatic intracerebral hemorrhage in acute ischemic stroke of large vessel occlusion.

Abstract
BACKGROUND AND PURPOSE With increasing use of endovascular therapy, physicians' attitudes toward intravenous alteplase in endovascular therapy-eligible patients may be changing. We explored current intravenous alteplase treatment practices of physicians in endovascular therapy- and alteplase-eligible patients with acute stroke using prespecified case scenarios and compared how their current local treatment practices differ compared with an assumed ideal environment. MATERIALS AND METHODS In an international multidisciplinary survey, 607 physicians involved in acute stroke care were randomly assigned 10 of 22 case scenarios, among them 14 with guideline-based alteplase recommendations (9 with level 1A and 5 with level 2B recommendation) and were asked how they would treat the patient: A) under their current local resources, and B) under assumed ideal conditions. Answer options were the following: 1) anticoagulation/antiplatelet therapy, 2) endovascular therapy, 3) endovascular therapy plus intravenous alteplase, and 4) intravenous alteplase. Decision rates were calculated, and multivariable regression analysis was performed to determine variables associated with the decision to abandon intravenous alteplase. RESULTS In cases with guideline recommendations for alteplase, physicians favored alteplase in 82.0% under current local resources and in 79.3% under assumed ideal conditions (P < .001). Under assumed ideal conditions, interventional neuroradiologists would refrain from intravenous alteplase most often (6.28%, OR = 2.40; 95% CI, 1.01-5.71). When physicians' current and ideal decisions differed, most would like to add endovascular therapy to intravenous alteplase in an ideal setting (196/3861 responses, 5.1%). CONCLUSIONS In patients eligible for endovascular therapy and intravenous alteplase, we observed a slightly lower decision rate in favor of intravenous alteplase under assumed ideal conditions compared with the decision rate under current local resources.

Abstract
PURPOSE OF REVIEW To summarize available evidence on the potential utility of pretreatment with intravenous thrombolysis (IVT) using recombinant tissue-plasminogen activator (rt-PA) in acute ischemic stroke (AIS) patients with large vessel occlusions (LVO) who are treated with mechanical thrombectomy. RECENT FINDINGS Despite theoretical concerns of a higher bleeding risk with IVT pretreatment, there are no data showing increased risk of symptomatic intracerebral hemorrhage (sICH) in patients with LVO receiving bridging therapy (IVT and mechanical thrombectomy) compared with direct mechanical thrombectomy (dMT). Additionally, evidence from observational studies suggest lower rates of infarctions in previously unaffected territories and higher rates of successful reperfusion, with lower number of device passes, in patients receiving bridging therapy. There are substantial discrepancies in studies comparing clinical outcomes between dMT and bridging therapy that are directly related to the inclusion of patients with contraindications to IVT in the dMT group. Ongoing clinical trials will provide definitive answers on the potential additional benefit of IVT in LVO patients receiving mechanical thrombectomy. SUMMARY IVT and mechanical thrombectomy are two effective reperfusion therapies that should be used in a swift and noncompeting fashion in AIS patients. AIS patients with LVO and no contraindications for IVT should receive promptly rt-PA bolus followed by immediate initiation of mechanical thrombectomy as indicated by current international recommendations, unless future randomized controlled trials provide evidence to proceed differently.

Abstract
BACKGROUND Whether bridging strategies[intravenous thrombolysis (IVT) + mechanical thrombectomy (MT)] are superior to mechanical thrombectomy alone for large vessel occlusion(LVO) is still uncertain. A systematic review and meta-analysis was conducted to investigate and evaluate comparative efficacy and safety of bridging strategies vs direct MT in patients with LVO. METHODS The PubMed, EMBASE and Cochrane library databases were searched to evaluate the efficacy and safety of bridging strategies with direct MT in LVO. Functional independence, mortality, symptomatic intracranial hemorrhage (sICH) and successful recanalization were assessed. The risk ratio (RR) and its 95% confidence interval (CI) were calculated. RESULTS The proportion of patients who received MT + IVT was significantly higher in functional independence and successful recanalization rate than MT alone patients. However, pooled results showed that the mortality of patients who received MT + IVT was significantly lower than that of MT alone patients. Moreover, no significant differences were observed in the incidence of sICH between the 2 groups. CONCLUSION The findings of our meta-analysis confirmed that bridging strategies improved functional outcomes, successful recanalization rate and reduced mortality rates. Moreover, the incidence of sICH showed no differences between the bridging strategies and MT alone treatments. However, the conduct of high-quality randomized clinical trials that directly compare both strategies is warranted.

Abstract
BACKGROUND Whether pretreatment with intravenous thrombolysis prior to mechanical thrombectomy (IVT+MTE) adds additional benefit over direct mechanical thrombectomy (dMTE) in patients with large vessel occlusions (LVO) is a matter of debate. METHODS This study-level meta-analysis was presented in accord with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Pooled effect sizes were calculated using the inverse variance heterogeneity model and displayed as summary Odds Ratio (sOR) and corresponding 95% confidence interval (95% CI). Sensitivity analysis was performed by distinguishing between studies including dMTE patients eligible for IVT (IVT-E) or ineligible for IVT (IVT-IN). Primary outcome measures were functional independence (modified Rankin Scale≤2) and mortality at day 90, successful reperfusion, and symptomatic intracerebral hemorrhage. RESULTS Twenty studies, incorporating 5279 patients, were included. There was no evidence that rates of successful reperfusion differed in dMTE and IVT+MTE patients (sOR 0.93, 95% CI 0.68 to 1.28). In studies including IVT-IN dMTE patients, patients undergoing dMTE tended to have lower rates of functional independence and had higher odds for a fatal outcome as compared with IVT+MTE patients (sOR 0.78, 95% CI 0.61 to 1.01 and sOR 1.45, 95% CI 1.22 to 1.73). However, no such treatment group effect was found when analyses were confined to cohorts with a lower risk of selection bias (including IVT-E dMTE patients). CONCLUSION The quality of evidence regarding the relative merits of IVT+MTE versus dMTE is low. When considering studies with lower selection bias, the data suggest that dMTE may offer comparable safety and efficacy as compared with IVT+MTE. The conduct of randomized-controlled clinical trials seems justified.

Liu M, Li G. Is Direct Endovascular Treatment as an Alternative of Bridging Therapy in Acute Stroke Patients with Large Vessel Occlusion? J Stroke Cerebrovasc Dis 2018; 28:531-541. [PMID: 30595512 DOI: 10.1016/j.jstrokecerebrovasdis.2018.10.007] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2018] [Revised: 09/24/2018] [Accepted: 10/05/2018] [Indexed: 10/27/2022] Open
Abstract
BACKGROUND Although endovascular treatment (EVT) is very effective for acute ischemia stroke (AIS) patients with proximal large vessels occlusion (LVO), whether bridging rPA before EVT in stroke patients of LVO is of any benefit and is currently one of the most urgent unanswered questions. We aim to comprehensively determine the efficacy and safety of direct EVT (DEVT) in AIS patients with LVO versus bridging therapy (BT). METHODS Clinical researches published in the Embase, PubMed, and Cochrane Library electronic databases up to May 2017 were identified for analysis. Two reviewers extracted data and conducted quality assessment independently. Statistical tests were performed to check for heterogeneity and publication bias. Subgroup and sensitivity analysis were also conducted to evaluate the robustness of the conclusions. RESULTS Overall, 13 studies involving 3302 patients met the inclusion criteria. The AIS patients with DEVT had a similar likelihood to achieve good functional outcome at 3 months (risk ratio [RR] = .93, 95% confidence interval [CI] = .85-1.01, P = .094), mortality at 3 months (RR = 1.10, 95% CI = .91-1.33, P = .33), and symptomatic intracranial hemorrhage (RR = 1.06, 95% CI = .74-1.51, P = .75) versus BT; furthermore, the risk of intracranial hemorrhage was lower in DEVT group (RR = .76, 95% CI = .60-.95, P = .02). No significant difference in recanalization rate existed between the 2 groups (RR = .97, 95% CI = .92-1.02, P = .22); however, in the subgroup analysis, it had a rise trend after DEVT than BT in IVT-eligible group (RR = 1.45, 95% CI = .95-2.22, P = .09). CONCLUSIONS DEVT appears to have equally effectiveness to BT with a low risk of intracranial hemorrhage in AIS patients with LVO, especially for anterior circulation, which offered a practical information to select appropriate therapeutic strategies for patients with LVO, though the level of evidence seems to be quite shaky.

Effect of Clot Stiffness on Recombinant Tissue Plasminogen Activator Lytic Susceptibility in Vitro. ULTRASOUND IN MEDICINE & BIOLOGY 2018; 44:2710-2727. [PMID: 30268531 PMCID: PMC6551517 DOI: 10.1016/j.ultrasmedbio.2018.08.005] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/11/2018] [Revised: 08/01/2018] [Accepted: 08/10/2018] [Indexed: 05/05/2023]
Abstract
The lytic recombinant tissue plasminogen activator (rt-PA) is the only drug approved by the Food and Drug Administration for treating ischemic stroke. Less than 40% of patients with large vessel occlusions who are treated with rt-PA have improved blood flow. However, up to 6% of all patients receiving rt-PA develop intracerebral hemorrhage. Predicting the efficacy of rt-PA treatment a priori could help guide therapeutic decision making, such that rt-PA is administered only to those individuals who would benefit from this treatment. Clot composition and structure affect the lytic efficacy of rt-PA and have an impact on elasticity. However, the relationship between clot elasticity and rt-PA lytic susceptibility has not been adequately investigated. The goal of this study was to quantify the relationship between clot elasticity and rt-PA susceptibility in vitro. Human and porcine highly retracted and mildly retracted clots were fabricated in glass pipettes. The rt-PA lytic susceptibility was evaluated in vitro using the percent clot mass loss. The Young's moduli of the clots were estimated using ultrasound-based single-track-location shear wave elasticity imaging. The percent mass loss in mildly retracted porcine and human clots (28.9 ± 6.1% and 45.2 ± 7.1%, respectively) was significantly higher (p < 0.05) than in highly retracted porcine and human clots (10.9 ± 2.1% and 25.5 ± 10.0%, respectively). Furthermore, the Young's moduli of highly retracted porcine and human clots (5.33 ± 0.92 and 3.21 ± 1.97 kPa, respectively) were significantly higher (p < 0.05) than those of mildly retracted porcine and human clots (2.66 ± 0.55 and 0.79 ± 0.21 kPa, respectively). The results revealed an inverse relationship between the percent clot mass loss and Young's modulus. These findings motivate continued investigation of ultrasound-based methods to assess clot stiffness in order to predict rt-PA thrombolytic efficacy.

Abstract
PURPOSE The acute distal intracranial occlusion of the internal carotid artery (ICA) is a very complex heterogeneous pathology, characterized by various patterns. Aim of this work is to identify the different types and propose a classification. METHODS Among the patients admitted for stroke in the anterior circulation from august 2014 to October 2017, 46 (25%) presented with intracranial distal carotid artery occlusion. The mean age of the patients was 71 (SD 13.7), 65,2% female. The protocol included general and specific neurological examinations, CT, CT-Angiography with multiphase CTA, followed by Angiography. The occlusion was treated by aspiration device alone or associated with stent-retriever. NIHSS at the admission, at discharge and modified ranking Scale (mRS) at four months were examined. RESULTS The occlusions presented with various patterns. Depending on its site (located at the distal ICA bifurcation or more proximal at the level of the ophthalmic segment of ICA, with or without extent to ICA bifurcation) taking also into account the various involvement of the cerebral vessels and anatomic variations of Circle of Willis, three groups of occlusion types could be identified (T1, T2 and T3). The collateral circulation, and the possibilities of the endovascular revascularization important for the final outcome, were clearly connected with the type of occlusion. NIHSS at admission was 19.1 (Range from 8 to 30, SD 4.4). Good outcome defined as mRS 0-2 at for months was obtained in 17 patients (37%). CONCLUSIONS The proposed classification reproduces more precisely the complexity and heterogeneity of this pathology, being useful in the diagnosis and treatment of these patients.

Abstract
BACKGROUND The development of new revascularization devices has improved recanalization rates and time, but not clinical outcomes. We report a prospectively collected clinical experience with a new technique utilizing a direct aspiration first pass technique with large bore aspiration catheter as the primary method for vessel recanalization. METHODS 98 prospectively identified acute ischemic stroke patients with 100 occluded large cerebral vessels at six institutions were included in the study. The ADAPT technique was utilized in all patients. Procedural and clinical data were captured for analysis. RESULTS The aspiration component of the ADAPT technique alone was successful in achieving Thrombolysis in Cerebral Infarction (TICI) 2b or 3 revascularization in 78% of cases. The additional use of stent retrievers improved the TICI 2b/3 revascularization rate to 95%. The average time from groin puncture to at least TICI 2b recanalization was 37 min. A 5MAX demonstrated similar success to a 5MAX ACE in achieving TICI 2b/3 revascularization alone (75% vs 82%, p=0.43). Patients presented with an admitting median National Institutes of Health Stroke Scale (NIHSS) score of 17.0 (12.0-21.0) and improved to a median NIHSS score at discharge of 7.3 (1.0-11.0). Ninety day functional outcomes were 40% (modified Rankin Scale (mRS) 0-2) and 20% (mRS 6). There were two procedural complications and no symptomatic intracerebral hemorrhages. DISCUSSION The ADAPT technique is a fast, safe, simple, and effective method that has facilitated our approach to acute ischemic stroke thrombectomy by utilizing the latest generation of large bore aspiration catheters to achieve previously unparalleled angiographic outcomes.

Abstract
BackgroundMechanical thrombectomy using a stent retriever has become the standard of care for acute large-vessel occlusions in the anterior circulation. Clots that are refractory to single stent retriever thrombectomy remain a challenge for neurointerventionalists.ObjectiveTo assess the efficacy and safety of double stent retriever (crossing Y-Solitaire) thrombectomy as a rescue treatment for acute middle cerebral artery (MCA) occlusions that are refractory to single stent retriever thrombectomy.MethodsWe retrospectively reviewed the databases of our hospitals to identify patients who presented with an acute MCA occlusion and were treated with crossing Y-Solitaire thrombectomy. The angiographic (Thrombolysis in Cerebral Infarction (TICI) scale) and clinical outcomes (National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) scores) and complications were assessed.ResultsTen patients were included in the study. The median initial NIHSS score and Alberta Stroke Program Early CT Score (ASPECTS) were 19.0 and 9.6, respectively. Crossing Y-Solitaire thrombectomy was performed as a rescue technique after unsuccessful single Solitaire thrombectomy passes in all cases. Successful recanalization (TICI 2b/3) was achieved in 8 (80%) patients. We observed asymptomatic reperfusion hemorrhages in 2 (20%) patients. No procedural related complications were seen other than reversible vasospasms in 5 (50%) patients. Sixty percent of the patients had a mRS score of between 2 and 0 at 90 days after the procedure. There was no mortality.ConclusionCrossing Y-Solitaire thrombectomy seems to be an effective and safe alternative rescue technique to treat refractory MCA bifurcation occlusions that are refractory to standard thrombectomy procedures.

Abstract
OBJECTIVE A reperfusion quality of thrombolysis in cerebral infarction (TICI)≥2b has been set as the therapeutic angiography target for interventions in patients with acute ischaemic stroke. This study addresses whether the distinction between TICI2b and TICI3 reperfusions shows a clinically relevant difference on functional outcome. METHODS A systematic literature review and meta-analysis was carried out and presented in conformity with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria to test the primary hypothesis that TICI2b and TICI3 reperfusions are associated with different rates of modified Rankin Scale (mRS) ≤2 at day 90. Secondary endpoints included rates of haemorrhagic transformations, mortality and excellent functional outcome (mRS ≤1). Summary estimates of ORs (sOR) with 95% CI were calculated using the inverse variance heterogeneity model accounting for multiple true effect sizes. RESULTS Fourteen studies on 2379 successfully reperfused patients were included (1131 TICI3, 1248 TICI2b). TICI3 reperfusions were associated with higher rates of functional independence (1.74, 95% CI 1.44 to 2.10) and excellent functional outcomes (2.01, 95% CI 1.60 to 2.53), also after including adjusted estimates. The safety profile of patients with TICI3 was superior, as demonstrated by lower rates of mortality (sOR 0.59, 95% CI 0.37 to 0.92) and symptomatic intracranial haemorrhages (sOR 0.42, 95% CI 0.25 to 0.71). CONCLUSION TICI3 reperfusions are associated with superior outcome and better safety profiles than TICI2b reperfusions. This effect seems to be independent of time and collaterals. As reperfusion quality is the most important modifiable predictor of patients' outcome, a more conservative definition of successful therapy and further evaluation of treatment approaches geared towards achieving TICI3 reperfusions are desirable.

Abstract
BackgroundLimited post-marketing data exist on the use of the Solitaire FR device in clinical practice. The North American Solitaire Stent Retriever Acute Stroke (NASA) registry aimed to assess the real world performance of the Solitaire FR device in contrast with the results from the SWIFT (Solitaire with the Intention for Thrombectomy) and TREVO 2 (Trevo versus Merci retrievers for thrombectomy revascularization of large vessel occlusions in acute ischemic stroke) trials.MethodsThe investigator initiated NASA registry recruited North American sites to submit retrospective angiographic and clinical outcome data on consecutive acute ischemic stroke (AIS) patients treated with the Solitaire FR between March 2012 and February 2013. The primary outcome was a Thrombolysis in Myocardial Ischemia (TIMI) score of ≥2 or a Treatment in Cerebral Infarction (TICI) score of ≥2a. Secondary outcomes were 90 day modified Rankin Scale (mRS) score, mortality, and symptomatic intracranial hemorrhage.Results354 patients underwent treatment for AIS using the Solitaire FR device in 24 centers. Mean time from onset to groin puncture was 363.4±239 min, mean fluoroscopy time was 32.9±25.7 min, and mean procedure time was 100.9±57.8 min. Recanalization outcome: TIMI ≥2 rate of 83.3% (315/354) and TICI ≥2a rate of 87.5% (310/354) compared with the operator reported TIMI ≥2 rate of 83% in SWIFT and TICI ≥2a rate of 85% in TREVO 2. Clinical outcome: 42% (132/315) of NASA patients demonstrated a 90 day mRS ≤2 compared with 37% (SWIFT) and 40% (TREVO 2). 90 day mortality was 30.2% (95/315) versus 17.2% (SWIFT) and 29% (TREVO 2).ConclusionsThe NASA registry demonstrated that the Solitaire FR device performance in clinical practice is comparable with the SWIFT and TREVO 2 trial results.

Abstract
BACKGROUND Stent retriever thrombectomy (SRT) in acute thromboembolic stroke can result in post-thrombectomy subarachnoid hemorrhage (PTSAH). Intraprocedural findings associated with PTSAH are not well defined. OBJECTIVE To identify angiographic findings and procedural factors during SRT that are associated with PTSAH. MATERIALS AND METHODS This was a retrospective, observational cohort study of consecutive patients with middle cerebral artery (MCA) acute ischemic stroke treated with SRT. Inclusion criteria were: (1) age ≥18 years; (2) thromboembolic occlusion of the MCA; (3) at least one stent retriever pass beginning in an M2 branch; (4) postprocedural CT or MRI scan within 24 hours; (5) non-enhanced CT Alberta Stroke Program Early CT Score >5. Exclusion criteria included multi-territory stroke before SRT. RESULTS Eighty-five patients were enrolled; eight patients had PTSAH (group 1) and 77 did not (group 2). Baseline demographic and clinical characteristics were comparable between the two groups. In group 1, a significantly greater proportion of patients had more than two stent retriever passes (62.5% vs 18.2%, P=0.01), a stent retriever positioned ≥2 cm along an M2 branch (100% vs 30.2%, P=0.002), and the presence of severe iatrogenic vasospasm before SRT pass (37.5% vs 5.2%, P=0.02). One patient with PTSAH and associated mass effect deteriorated clinically. CONCLUSIONS An increased number of stent retriever passes, distal device positioning, and presence of severe vasospasm were associated with PTSAH. Neurological deterioration with PTSAH can occur.

Abstract
Objective The aim of this study was to determine outcome of ischemic stroke patients in the anterior circulation treated with endovascular treatment (EVT) with intravenous thrombolysis (IVT) versus EVT alone group. Methods A systemic literature review was performed using online database from January 2004 to January 2017. Primary outcomes were successful recanalization seen on finial angiography and good outcome at three months. Secondary outcomes were mortality and the development of symptomatic intracranial hemorrhage (S-ICH) after the procedure. A fixed effect model was used when heterogeneity was less than 50%. Egger’s regression test was used to assess publication bias. Results Five studies were included for final analysis. Between EVT with IVT and EVT alone group, successful recanalization (odds ratio [OR] 1.467, p=0.216), good clinical outcome at three months (OR 1.199, p=0.385), mortality (OR 0.776, p=0.371), and S-ICH (OR 1.820, p=0.280) did not differ significantly. Egger’s regression intercept with 95% confidence interval (CI) was 1.99 (95% CI -2.91 to 6.89) in successful recanalization and -0.27 (95% CI -6.35 to 5.80) in good clinical outcome, respectively. Conclusion The two treatment modalities, EVT with IVT and EVT alone, could be comparable in treating acute anterior circulation stroke. Studies to find specific beneficiary group for EVT alone, without primary IVT, are needed further.

Thrombectomy using the EmboTrap device: core laboratory-assessed results in 201 consecutive patients in a real-world setting. J Neurointerv Surg 2018; 10:964-968.

Abstract
BackgroundWe studied patients treated with the EmboTrap revascularization device in a prospective registry which is core laboratory evaluated by physicians from external centers. The goal was to determine how the EmboTrap would perform under the everyday conditions of a high-volume stroke center.MethodsWe examined all patients with acute stroke treated with the Embotrap device from October 2013 to March 2017 in our center. Imaging parameters and times were adjudicated by core laboratory personnel blinded to clinical information, treating physician, and clinical outcomes. Clinical evaluation was performed by independent neurologists and entered in a national registry. Evaluated endpoints were: successful revascularization (modified Thrombolysis in Cerebral Infarction (mTICI) 2b–3) and good clinical outcomes at 3 months (modified Rankin Scale (mRS) 0–2).Results201 consecutive patients with a median NIH Stroke Scale (NIHSS) score of 15 (range 2–30) were included. 170 patients (84.6%) achieved mTICI 2b–3 reperfusion. The median number of attempts was 2 (range 1–10) with 52.8% of the population achieving good functional outcomes (mRS 0–2) at 3 months. On univariate analysis, good functional outcome was associated with the number of attempts, puncture-to-reperfusion time, anterior circulation occlusion, and NIHSS score. On multivariate analysis, pre-treatment NIHSS (OR 0.845 per point, 95% CI 0.793 to 0.908, P<0.001) and puncture-to-reperfusion time (OR 0.9952 per min, 95% CI 0.9914 to 0.9975, P=0.023) were associated with good functional outcomes at 3 months.ConclusionThe Embotrap device has a high rate of successful reperfusion. Our core laboratory-audited single-center experience suggests the technical feasibility and safety of the Embotrap for first-line use in a real-world setting.

Comparative safety and efficacy of combined IVT and MT with direct MT in large vessel occlusion. Neurology 2018; 90:e1274-e1282.

Abstract
OBJECTIVE In this multicenter study, we sought to evaluate comparative safety and efficacy of combined IV thrombolysis (IVT) and mechanical thrombectomy (MT) vs direct MT in emergent large vessel occlusion (ELVO) patients. METHODS Consecutive ELVO patients treated with MT at 6 high-volume endovascular centers were evaluated. Standard safety and efficacy outcomes (successful reperfusion [modified Thrombolysis in Cerebral Infarction IIb/III], functional independence [FI] [modified Rankin Scale (mRS) score of 0-2 at 3 months], favorable functional outcome [mRS of 0-1 at 3 months], functional improvement [mRS shift by 1-point decrease in mRS score]) were compared between patients who underwent combined IVT and MT vs MT alone. Additional propensity score-matched analyses were performed. RESULTS A total of 292 and 277 patients were treated with combination therapy and direct MT, respectively. The combination therapy group had greater functional improvement (p = 0.037) at 3 months. After propensity score matching, 104 patients in the direct MT group were matched to 208 patients in the combination therapy group. IVT pretreatment was independently (p < 0.05) associated with higher odds of FI (odds ratio [OR] 1.75; 95% confidence interval [CI] 1.02-2.99) and functional improvement (common OR 1.64; 95% CI 1.05-2.56). Combination therapy was independently (p < 0.05) related to lower likelihood of 3-month mortality (0.50; 95% CI 0.26-0.96). CONCLUSIONS This observational study provides preliminary evidence that IVT pretreatment may improve outcomes in ELVO patients treated with MT. The question of the potential effect of IVT on ELVO patients treated with MT should be addressed with a randomized controlled trial. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that for stroke patients with emergent large vessel occlusion, combined IVT and MT is superior to direct MT in improving functional outcomes.

Abstract
BACKGROUND Whether intravenous thrombolysis (IVT) before mechanical thrombectomy (MT) provides additional benefits remains controversial. We aimed to compare clinical and radiologic outcomes between IVT+MT and MT alone groups. METHODS We retrospectively reviewed the clinical and radiological features of patients from the prospectively collected database who sustained anterior circulation stroke due to large vessel occlusion (LVO) and were treated with MT within 8 hours of symptom onset. We compared rates of successful reperfusion, functional independence and mortality at 90 days, and symptomatic intracranial hemorrhage (sICH) as clinical endpoints between the 2 groups. RESULTS The 81 patients included in this study included 38 (46.9%) in the MT alone group (mean age, 72.6 ± 14.1 years; 17 males [44.7%]) and 43 in the IVT+MT group (mean age, 68.9 ± 12.8 years; 29 males [67.4%]). There were no significant differences in patient baseline characteristics between the 2 groups except for a male predominance in the IVT+MT group. The mean interval from onset to groin puncture (221.6 ± 110.5 minutes vs. 204.7 ± 63.7 minutes; P = 0.472) and the rate of successful reperfusion rate (thrombolysis in cerebral infarction 2b/3, 60.5% vs. 58.1%; P = 0.827) did not differ significantly between the MT and IVT+MT groups. The rate of favorable functional outcome, as determined by a modified Rankin Scale score 0-2 (36.8% vs. 51.2%; P = 0.263) and mortality at 90 days (18.4% vs. 9.3%; P = 0.332), and the rate of sICH (5.3% vs. 4.6%; P = 1.000) were also not significantly different between the 2 groups. CONCLUSIONS This study suggests that previous IVT might not facilitate successful reperfusion and favorable functional outcomes in patients with anterior circulation stroke treated with MT. MT alone can be a safe and effective treatment modality in patients who are ineligible for IVT for various reasons.

Acta Neurol Belg 2018; 118:105-111. [PMID: 29435828 DOI: 10.1007/s13760-018-0892-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2017] [Accepted: 02/01/2018] [Indexed: 11/26/2022]
Abstract
The majority of patients undergoing endovascular stroke treatment (EST) in randomized controlled trials received additional systemic thrombolysis ("combination or bridging therapy (C/BT)"). Nevertheless, its usefulness in this subtype of acute ischemic stroke (AIS) is discussed controversially. Of all consecutive AIS patients, who received any kind of reperfusion therapy in a tertiary university stroke center between January 2015 and March 2016, those with large vessel occlusions (LVO) and EST with or without additional C/BT, were compared primarily regarding procedural aspects. Data were extracted from an investigator-initiated, single-center, prospective and blinded end-point study. 70 AIS patients with EST alone and 118 with C/BT were identified. Significant baseline differences existed in pre-existing cardiovascular disease (52.9% (EST alone) vs. 35.6% (C/BT), p = 0.023), use of anticoagulation (30.6% vs. 5.9%, p < 0.001), and frequency of unknown time of symptom onset (65.7% vs. 32.2%, p < 0.001), in-hospital stroke (18.6% vs. 1.7%, p < 0.001), pre-treatment ASPECT scores (7.9 vs. 8.9, p = 0.004), and frequency of occlusion in the posterior circulation (18.6% vs. 5.1%, p = 0.003). Pre-interventional procedural time intervals tended to be shorter in the C/BT group, reaching statistical significance in door-to-image time (30.3 (EST alone) vs. 22.2 min (C/BT), p < 0.001). Good clinical outcome (mRS d90) was reached more often in the C/BT group (24.5% vs. 11.8%, p = 0.064). Rates of symptomatic intracranial hemorrhages (sICH) were comparable (4.3% (EST alone) vs. 6.8% (C/BT), p = 0.481). Additional systemic thrombolysis did not delay EST. On the contrary, application of IVRTPA seemed to be a positive indicator for faster EST without increased side effects.

Abstract
Following the success of recent endovascular trials, endovascular therapy has emerged as an exciting addition to the arsenal of clinical management of patients with acute ischemic stroke (AIS). In this paper, we present an extensive overview of intravenous and endovascular reperfusion strategies, recent advances in AIS neurointervention, limitations of various treatment paradigms, and provide insights on imaging-guided reperfusion therapies. A roadmap for imaging guided reperfusion treatment workflow in AIS is also proposed. Both systemic thrombolysis and endovascular treatment have been incorporated into the standard of care in stroke therapy. Further research on advanced imaging-based approaches to select appropriate patients, may widen the time-window for patient selection and would contribute immensely to early thrombolytic strategies, better recanalization rates, and improved clinical outcomes.

Abstract
Endovascular mechanical thrombectomy (MT) is reserved for acute ischaemic stroke secondary to large vessel occlusion. The various MT techniques employed in the treatment of hyperacute strokes are constantly evolving with new devices and improvisation of existing technology (Wahlgren, et al 2016). In this review, we describe a variety of MT techniques gained from our experience of performing over 350 procedures in 7 years of providing a 24/7 service within the national framework of a hyperacute stroke centre. We outline a number of endovascular techniques, procedure limitations, and potential complications.

Abstract
Objective To investigate the effect of mechanical thrombectomy with solitaire stent in the treatment of acute ischemic stroke with large cerebral artery occlusion. Methods Fifteen acute ischemic stroke patients with a proximal intracranial occlusion in the anterior circulation were included within 6 hours after symptom onset (unknown time of onset allowed in wake upstroke). Patients with a large infarct core or poor collateral circulation on computed tomography (CT) and CT angiography were excluded. All patients were measured by the National Institutes of Health Stroke Scale (NIHSS) before and 24 hours after the procedure. The primary outcomes were reperfusion at 24 hours and a Thrombolysis in Cerebral Infarction (TICI) score of 2b or 3 indicates successful reperfusion. Secondary outcomes included the functional score on the Modified Rankin Scale(MRS) and NIHSS score at 90 days. Good Functional Outcome (GFO), is defined as mRS0–2 at 90 days. Results The preoperative TICI grading of these 15 patients were all level 0.14 patients were level 2b to level 3 after the thrombectomy, 1 ipsilateral cervical carotid occlusion patient failed recanalization.14 patients with reperfusion at 24 hours showed good early neurologic improvement. The MRS score of all the 14 patients were<2 point at 90 days. There were no obvious adverse reactions and complications in these patients after mechanical thrombectomy. Conclusion The application of mechanical thrombectomy with solitaire stent for the treatment of acute ischemic stroke with large cerebral artery occlusion is safe and time-efficient, which could improve the recanalization rate, decrease or even eliminate the application of thrombolytic drugs and reduce the rate of intracranial hemorrhage. Awake stroke patient can also benefit from thrombectomy.

Abstract
Mechanical thrombectomy with a stent retriever has been reported to achieve high rates of successful recanalization, and reduce disability and mortality in patients with acute ischemic stroke (AIS) due to proximal vessel occlusion. However, in a few cases, the treatment is difficult due to artery tortuosity or other factors. The authors present a case of a 94-year-old man presenting with acute right middle cerebral artery occlusion. We attempted to treat using a stent retriever via transfemoral approach, but failed to advance the guiding catheter into the right internal carotid artery due to femoral artery tortuosity and a type III arch. By changing approaches from transfemoral to transbrachial and by using TrevoProVue through a 4.2 Fr Simmons-type catheter without a guiding catheter, we were able to achieve rapid recanalization in only 26 minutes from brachial artery puncture to reperfusion. In conclusion, rapid reperfusion in an AIS patient was successfully achieved by combining a stent retriever with a 4.2 Fr catheter (without a guiding catheter) and a transbrachial approach (as opposed to a transfemoral approach). When the transfemoral approach is not feasible, we recommend consideration of this strategy as an alternative.

Abstract
Background Various techniques are used to enhance the results of mechanical thrombectomy with stent-retrievers, including proximal arrest with balloon guide catheter (BGC), conventional large bore proximal catheter (CGC), or in combination with local aspiration through a large-bore catheter positioned at the clot interface (Aspiration-Retriever Technique for Stroke [ARTS]). We evaluated the impact of ARTS in the North American Solitaire Acute Stroke (NASA) registry. Summary Data on the use of the aspiration technique were available for 285 anterior circulation patients, of which 29 underwent ARTS technique, 131 CGC, and 125 BGC. Baseline demographics were comparable, except that ARTS patients are less likely to have hypertension or atrial fibrillation. The ARTS group had more ICA occlusions (41.4 vs. 22% in the BGC, p = 0.04 and 26% in CGC, p = 0.1) and less MCA/M1 occlusions (44.8 vs. 68% in BGC and 62% in CGC). Time from arterial puncture to reperfusion or end of procedure with ARTS was shorter than with CGC (54 vs. 91 min, p = 0.001) and was comparable to the BGC time (54 vs. 67, p = 0.11). Final degree of reperfusion was comparable among the groups (TICI [modified Thrombolysis in Cerebral Infarction] score 2b or higher was 72 vs. 70% for CGC vs. 78% for BGC). Procedural complications, mortality, and good clinical outcome at 90 days were similar between the groups. Key Messages The ARTS mechanical thrombectomy in acute ischemic stroke patients appears to yield better results as compared to the use of CGCs with no significant difference when compared to BGC. This early ARTS technique NASA registry data are limited by the earlier generation distal large bore catheters and small sample size. Future studies should focus on the comparison of ARTS and BGC techniques.
