Background and Purpose— Patients with acute ischemic stroke treated with endovascular thrombectomy may be treated with repeat endovascular thrombectomy (rEVT) in case of recurrent large vessel occlusion. Data on safety and efficacy of these interventions is scarce. Our aim is to report on frequency, timing, and outcome of rEVT in a large nation-wide multicenter registry. Methods— In the Netherlands, all patients with endovascular thrombectomy have been registered since 2002 (MR CLEAN Pretrial registry, MR CLEAN Trial [Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands], and MR CLEAN Registry). We retrospectively reviewed these databases for anterior circulation rEVT cases. Patient characteristics, procedural data, and functional outcome (modified Rankin Scale at 90 days) were analyzed. Results— Of 3928 patients treated between 2002 and 2017, 27 (0.7%) underwent rEVT. Median time between first and second procedure was 78 (1–1122) days; 11/27 patients were re-treated within 30 days. Cardioembolism was the most common etiology (18 patients [67%]). In 19 patients (70%), recurrent occlusion occurred ipsilateral to previous occlusion. At 90 days after rEVT procedure, 44% of the patients had achieved functional independence (modified Rankin Scale score of 0–2), and 33% had died. Adverse events were 2/27 (7.4%) intracranial hemorrhage, 1/27 (3.7%) stroke progression, and 1/27 (3.7%) pneumonia. Conclusions— In this large nationwide cohort of patients with acute ischemic stroke treated with endovascular thrombectomy, rEVT was rare. Stroke cause was mainly cardio-embolic, and most recurrent large vessel occlusions in which rEVT was performed occurred ipsilateral. Although there probably is a selection bias on repeated treatment in case of recurrent large vessel occlusion, rEVT appears safe, with similar outcome as in single-treated cases.

<b><i>Introduction:</i></b> The management and prognosis of acute ischemic stroke due to multiple large-vessel occlusion (LVO) (MLVO) are not well scrutinized. We therefore aimed to elucidate the differences in patient characteristics and prognosis of MLVO and single LVO (SLVO). <b><i>Methods:</i></b> The Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism Japan Registry 2 (RESCUE-Japan Registry 2) enrolled 2,420 consecutive patients with acute LVO who were admitted within 24 h of onset. We compared patient prognosis between MLVO and SLVO in the favorable outcome, defined as a modified Rankin Scale (mRS) score ≤2, and in mortality at 90 days by adjusting for confounders. Additionally, we stratified MLVO patients into tandem occlusion and different territories, according to the occlusion site information and also examined their characteristics. <b><i>Results:</i></b> Among the 2,399 patients registered, 124 (5.2%) had MLVO. Although there was no difference between the 2 groups in terms of hypertension as a risk factor, the mean arterial pressure on admission was significantly higher in MLVO (115 vs. 107 mm Hg, <i>p</i> = 0.004). MLVO in different territories was more likely to be cardioembolic (42.1 vs. 10.4%, <i>p</i> = 0.0002), while MLVO in tandem occlusion was more likely to be atherothrombotic (39.5 vs. 81.3%, <i>p</i> &#x3c; 0.0001). Among MLVO, tandem occlusion had a significantly longer onset-to-door time than different territories (200 vs. 95 min, <i>p</i> = 0.02); accordingly, the tissue plasminogen activator administration was significantly less in tandem occlusion (22.4 vs. 47.9%, <i>p</i> = 0.003). However, interestingly, the endovascular thrombectomy (EVT) was performed significantly more in tandem occlusion (63.2 vs. 41.7%; adjusted odds ratio [aOR], 2.3; 95% confidence interval [CI], 1.1–5.0). The type of MLVO was the only and significant factor associated with EVT performance in multivariate analysis. The favorable outcomes were obtained less in MLVO than in SLVO (28.2 vs. 37.1%; aOR, 0.48; 95% CI, 0.30–0.76). The mortality rate was not significantly different between MLVO and SLVO (8.9 vs. 11.1%, <i>p</i> = 0.42). <b><i>Discussion/Conclusion:</i></b> The prognosis of MLVO was significantly worse than that of SLVO. In different territories, we might be able to consider more aggressive EVT interventions.

Background Statins have been associated with reduced recurrence and better functional outcomes in patients with acute ischemic stroke. However, the effect of statins in patients with acute large vessel occlusion (LVO) is not well scrutinized. Methods and Results RESCUE (Recovery by Endovascular Salvage for Cerebral Ultra‐Acute Embolism)‐Japan Registry 2, a physician‐initiated registry, enrolled 2420 consecutive patients with acute LVO who were admitted to 46 centers across Japan within 24 hours of onset. We compared patients with and without statin use after acute LVO onset (statin group and nonstatin group, respectively) in terms of the modified Rankin scale at 90 days. We estimated that the odds ratios for the primary outcome was modified Rankin scale and we estimated the odds ratios for a 1‐scale lower modified Rankin scale adjusting for confounders. After excluding 12 patients without LVO and 9 patients without follow‐up, the mean age of 2399 patients was 75.9 years; men accounted for 55% of patients. Statins were administered to 447 (19%) patients after acute LVO onset. Patients in the statin group had more atherothrombotic cerebral infarctions (34.2% versus 12.1%, P <0.0001), younger age (73.4 years versus 76.5 years, P <0.0001), and lower median National Institutes of Health Stroke Scale on admission (14 versus 17, P <0.0001) than the nonstatin group. The adjusted common OR of the statin group for lower modified Rankin scale was 1.29 (95% CI, 1.04–1.37; P =0.02). The mortality at 90 days was lower in the statin group (4.7%) than the nonstatin group (12.5%; P <0.0001). The adjusted OR of the statin group relative to the nonstatin group for mortality was 0.36 (95% CI, 0.21–0.62; P =0.02). Conclusions Statin administration after acute LVO onset is significantly associated with better functional outcome and mortality at 90 days.

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.

Background and Purpose: White matter hyperintensity (WMH), a marker of chronic cerebral small vessel disease, might impact the recruitment of leptomeningeal collaterals. We aimed to assess whether the WMH burden is associated with collateral circulation in patients treated by endovascular thrombectomy for anterior circulation acute ischemic stroke. Methods: Consecutive acute ischemic stroke due to anterior circulation large vessel occlusion and treated with endovascular thrombectomy from January 2015 to December 2017 were included. WMH volumes (periventricular, deep, and total) were assessed by a semiautomated volumetric analysis on fluid-attenuated inversion recovery–magnetic resonance imaging. Collateral status was graded on baseline catheter angiography using the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology grading system (good when ≥3). We investigated associations of WMH burden with collateral status. Results: A total of 302 patients were included (mean age, 69.1±19.4 years; women, 55.6%). Poor collaterals were observed in 49.3% of patients. Median total WMH volume was 3.76 cm 3 (interquartile range, 1.09–11.81 cm 3 ). The regression analyses showed no apparent relationship between WMH burden and the collateral status measured at baseline angiography (adjusted odds ratio, 0.987 [95% CI, 0.971–1.003]; P =0.12). Conclusions: WMH burden exhibits no overt association with collaterals in large vessel occlusive stroke.

AbstractIn the past 5 years, the success of multiple randomized controlled trials of recanalization therapy with endovascular thrombectomy has transformed the treatment of acute ischemic stroke with large vessel occlusion. The evidence from these trials has now established endovascular thrombectomy as standard of care. This review will discuss the chronological evolution of large vessel occlusion treatment from early medical therapy with tissue plasminogen activator to the latest mechanical thrombectomy. Additionally, it will highlight the potential areas in endovascular thrombectomy for acute ischemic stroke open to exploration and further progress in the next decade.

Background Acute ischemic stroke patients with a large-vessel occlusion but mild symptoms (NIHSS ≤ 6) pose a treatment dilemma between medical management and endovascular thrombectomy. Aims To evaluate the differences in clinical outcomes of endovascular thrombectomy-eligible patients with target-mismatch perfusion profiles who undergo either medical management or endovascular thrombectomy. Methods Forty-seven patients with acute ischemic stroke due to large-vessel occlusion, NIHSS ≤ 6, and a target-mismatch perfusion imaging profile were included. Patients underwent medical management or endovascular thrombectomy following treating neurointerventionalist and neurologist consensus. The primary outcome measure was NIHSS shift. Secondary outcome measures were symptomatic intracranial hemorrhage, in-hospital mortality, and 90-day mRS scores. The primary intention-to-treat and as-treated analyses were compared to determine the impact of crossover patient allocation on study outcome measures. Results Forty-seven patients were included. Thirty underwent medical management (64%) and 17 underwent endovascular thrombectomy (36%). Three medical management patients underwent endovascular thrombectomy due to early clinical deterioration. Presentation NIHSS ( P = 0.82), NIHSS shift ( P = 0.62), and 90-day functional independence (mRS 0–2; P = 0.25) were similar between groups. Endovascular thrombectomy patients demonstrated an increased overall rate of intracranial hemorrhage (35.3% vs. 10.0%; P = 0.04), but symptomatic intracranial hemorrhage was similar between groups ( P = 0.25). In-hospital mortality was similar between groups ( P = 0.46), though all two deaths in the medical management group occurred among crossover patients. Endovascular thrombectomy patients demonstrated a longer length of stay (7.6 ± 7.2 vs. 4.3 ± 3.9 days; P = 0.04) and a higher frequency of unfavorable discharge to a skilled-nursing facility ( P = 0.03) rather than home ( P = 0.05). Conclusions Endovascular thrombectomy may pose an unfavorable risk-benefit profile over medical management for endovascular thrombectomy-eligible acute ischemic stroke patients with mild symptoms, which warrants a randomized trial in this subpopulation.
