Background: Time to reperfusion remains one of the strongest predictors of outcome in large vessel occlusion strokes (LVOS). Herein, we aim to assess the impact of unfavorable vascular anatomy on mechanical thrombectomy (MT) number of passes and procedural times. Methods: Retrospectively review of a prospective MT database spanning January-July 2018 including acute LVOS involving the middle cerebral artery-M1 segment and available baseline CT angiography. The AIM2 score (Table 1) was applied with patients categorized as favorable (AIM2: 0-2) versus unfavorable (AIM2: >=3) anatomy. The primary outcome was the rate of <3 device passes. Secondary outcomes included procedural times and the rates of successful reperfusion (mTICI2b-3) and 90-day mRS 0-2. Safety measures included rates of sICH and 90-day mortality. Results: Patients with unfavorable anatomy (n=15) were significantly younger (52±19, p=0.02) and had lower rates of hypertension (46% vs 80%, p=0.01) and smoking (0% vs 39%, p<0.001) versus those with favorable anatomy (n=50). Successful reperfusion with <3 passes was more often achieved with AIM2 scores 0-2 vs. ≥3 (84% vs 60%, p=0.04). There were no significant difference in other outcome measures (Table 2). Conclusions: The AIM2 score system represents a simple method for the systematically evaluation of vascular anatomy in MT and correlates significantly with increased number of MT passes.

BackgroundEndovascular thrombectomy has demonstrated benefit for patients with acute ischemic stroke from proximal large vessel occlusion. However, limited evidence is available from recent randomized trials on the role of thrombectomy for M2 segment occlusions of the middle cerebral artery (MCA).MethodsWe conducted a systematic review and meta-analysis to investigate clinical and radiographic outcomes, rates of hemorrhagic complications, and mortality after M2 occlusion thrombectomy using modern devices, and compared these outcomes against patients with M1 occlusions. Recanalization was defined as Thrombolysis in Cerebral Infarction (TICI) 2b/3 or modified TICI 2b/3.ResultsA total of 12 studies with 1080 patients with M2 thrombectomy were included in our analysis. Functional independence (modified Rankin Scale 0–2) rate was 59% (95% CI 54% to 64%). Mortality and symptomatic intracranial hemorrhage rates were 16% (95% CI 11% to 23%) and 10% (95% CI 6% to 16%), respectively. Recanalization rates were 81% (95% CI 79% to 84%), and were equally comparable for stent-retriever versus aspiration (OR 1.05; 95% CI 0.91 to 1.21). Successful M2 recanalization was associated with greater rates of favorable outcome (OR 4.22; 95% CI 1.96 to 9.1) compared with poor M2 recanalization (TICI 0–2a). There was no significant difference in recanalization rates for M2 versus M1 thrombectomy (OR 1.05; 95% CI 0.77 to 1.42).ConclusionsThis meta-analysis suggests that mechanical thrombectomy for M2 occlusions that can be safely accessed is associated with high functional independence and recanalization rates, but may be associated with an increased risk of hemorrhage.

The Impact

<b><i>Background:</i></b> The impact of the length of the occluded vessel in acute large-vessel occlusion on successful reperfusion by mechanical thrombectomy remains unclear. This study evaluated whether diameter and length of the occluded vessel in acute middle cerebral artery (MCA) occlusion might relate to successful reperfusion following mechanical thrombectomy. <b><i>Methods:</i></b> This retrospective study included patients with acute MCA occlusion who underwent intra-aortic injection of contrast medium to obtain maximum intensity projection (MIP) images acquired by flat-panel detector computed tomography (FD-CT) equipped with an angiographic system. All patients received mechanical thrombectomy and were divided into two groups: those with successful reperfusion (Thrombolysis in Cerebral Infarction [TICI] 2b/3) and those without. We compared the diameter and length of the occluded vessel between the groups. In the sub-analysis of patients with stent retriever use, ratio of length of occluded vessel to length of the active zone was compared. <b><i>Results:</i></b> We enrolled 29 patients (median age: 73, M1 occlusion: 51%, stent retriever use: 72%). Eighteen patients achieved TICI 2b/3 with significantly larger distal end diameter (1.7 [interquartile range: 1.5–1.9] vs. 1.2 [1.2–1.5] mm, <i>p</i> = 0.007) and shorter length (7.1 [4.9–9.7] vs. 12.3 [7.2–15.8] mm, <i>p</i> = 0.043) of the occluded vessel. Sub-analysis of 21 patients showed that the cut-off value for TICI 2b/3 reperfusion was 0.32 as the ratio between the occluded vessel and stent retriever active zone (receiver operating characteristic area under the curve: 0.90). <b><i>Conclusion:</i></b> In acute MCA occlusion, larger diameter of the distal end and shorter length of the occluded vessel on FD-CT MIP images might indicate a higher possibility of achieving TICI 2b/3 following mechanical thrombectomy.

Background: Mechanical thrombectomy for anterior-circulation large-vessel occlusion has shown benefit; however, the question of whether this technique is safe and effective in the distal vasculature remains unanswered. We sought to compare the outcome data from mechanical thrombectomy of the M2 branches of the middle cerebral artery (MCA) with those of the M1 segment. Methods: We performed a retrospective analysis of prospectively collected data of patients with acute ischaemic stroke undergoing mechanical thrombectomy of isolated M1 or M2 branches of the MCA between August 2008 and August 2016. Results: We identified 585 patients, 479 with M1 occlusions and 106 with M2 occlusions. The average age was 72 ± 12.8 and 68 ± 13.8 years, respectively (p = 0.007). The baseline Alberta Stroke Program Early Computed Tomographic (ASPECT) score was similar in both cohorts, but patients with M1 occlusions presented with higher mean National Institutes of Health Stroke Scale (NIHSS) scores of 15.7 compared to 11.8 (p < 0.001). There was no significant difference in the average procedure time for each cohort; fewer thrombectomy attempts were required in the M2 cohort (2.3 vs. 1.8, p = 0.0004), but the overall time to recanalization was longer in the M2 cohort (353 vs. 399 min, p < 0.001). Similar rates of successful reperfusion (Thrombolysis in Ischaemic Stroke score [TICI] ≥2b 88.5 vs. 90.5%, p = 0.612) were seen, but food outcome (modified Rankin Scale ≤2) was lower in M1 occlusions (37.2 vs. 54.3%, p < 0.001). Rates of symptomatic intracranial haemorrhage were similar. Conclusion: Good clinical outcomes can be achieved for both groups with no significant differences in procedure length, final TICI recanalization rates or intracranial haemorrhage between the M1 and M2 cohorts.

Introduction: Solumbra technique involves the simultaneous use of stent-retriever and large-bore aspiration for clot retrieval in mechanical thrombectomy (MT). We aim to compare various time parameters in patients who undergo MT via solumbra technique via transradial artery (TRA) approach vs. transfemoral artery (TRF) approach. Methods: We performed a retrospective chart review of patients who underwent MT via solumbra technique for anterior circulation large vessel occlusion at a comprehensive stroke center from 7/2014 to 5/2020. We compared time to recanalization parameters, score of TICI≥2b, and functional independence (3-month mRS≤2) in patients who underwent MT via TRA vs.TRF approach via the solumbra technique. A binary logistic regression analysis was performed, controlling for age, sex, pre-treatment-NIHSS, type of anesthesia (general vs.moderate), laterality, and clot location [proximal (internal carotid or M1 segment of the middle cerebral artery) vs.distal (M2 or M3 segment of the middle cerebral artery)]. Results: A total of 98 patients met our inclusion criteria. The mean age was 63.59±14.40 years. 18 (18.37%) patients underwent MT through transradial approach. In our cohort, there was a significant association of TRA with shorter angio suite arrival-time to puncture-time (22.12±9.92mins vs.28.83±12.26mins; OR, 0.94; 95% CI, 0.88-1; P 0.026), but not with puncture-time to recanalization-time (84.34±61.34mins vs.63.73±35.29mins; OR, 1.01; 95% CI, 1-1.03; P 0.085), angio suite arrival-time to recanalization-time (103.12±51.29mins vs.93.42±39.08mins; OR, 1.01; 95% CI, 1-1.02; P 0.524), number of passes to recanalization (1.78±1.36 vs.1.68±1.05; OR, 1.03; 95% CI, 0.66-1.63 ; P 0.899), number of patients with TICI≥2b (83.34% vs.91.25%; OR, 0.68; 95% CI, 0.14-3.4; P 0.633), and functional independence (66.67% vs.78.75%; OR, 0.49; 95% CI, 0.13-1.86; P 0.292), when compared to TRF approach for MT using solumbra technique. Conclusion: Our study demonstrates a significant association between TRA approach with shorter angio suite arrival-time to puncture-time but not with overall time to recanalization, number of patients with TICI≥2b, and functional independence, when compared to TRF approach for MT using solumbra technique.

Introduction: Recent trials demonstrated that mechanical thrombectomy improve functional outcome in anterior circulation acute ischemic stroke (AIS) due to emergent large vessel occlusion (ELVO) of the middle cerebral artery (MCA) M1 segment. However, such data regarding AIS due to MCA M2 segment ELVO is limited. Analysis of the STAR, SWIFT, and SWIFT-PRIME trials found thrombectomy in MCA M2 occlusion to be feasible in achieving successful reperfusion. The most optimal technique and/or device used for such reperfusion is not clearly defined. We aim to compare the outcome for the contemporary techniques and devices used for thrombectomy of AIS patients due to MCA M2 ELVO. Methods: A retrospective review of AIS patients with MCA M2 ELVO receiving thrombectomy from three tertiary care academic medical centers was conducted. Thrombectomy technique and thrombectomy device utilized were recorded. Outcomes were successful angiographic reperfusion (TICI ≥2b), favorable modified Rankin Scale (mRS≤2) at discharge and at 90 days, and rate of symptomatic intracerebral hemorrhage (sICH). Results: From October 1999 through June 2016, 253 AIS patients underwent thrombectomy for MCA M2 ELVO. Thrombectomy methods utilized were Stent-retriever (n=118), Aspiration only [manual or Penumbra device] (n=83), and MERCI retriever (n=52). Table 1 shows rate of outcomes measured. There was no difference in baseline NIHSS or in stroke onset to groin puncture time. Stent-retriever group showed a significantly higher recanalization rate, lower sICH rate, and favorable 90-day mRS versus Aspiration group or MERCI group, respectively. No significant difference was seen in discharge mRS between the groups. Conclusions: Thrombectomy for AIS patients with MCA M2 ELVO with Stent-retriever appears to be feasible with a significantly higher rate of recanalization, lower sICH rate, and favorable 90-day mRS when compared to Aspiration and MERCI.

Background Mechanical thrombectomy has become the standard care for acute ischemic stroke caused by large vessel occlusion. However, complete reperfusion cannot be achieved in all cases, and several factors influencing the results of mechanical thrombectomy have been investigated. Among others, a tortuous anatomy is associated with lower rates of complete reperfusion. We aimed to investigate whether an early division of the middle cerebral artery has an impact on reperfusion results in mechanical thrombectomy. Methods Retrospective review of consecutive patients with M1 occlusion treated endovascularly between January 2016 and December 2019 at three tertiary care centers. The study group was dichotomized based on the length of the M1 segment. Early division of the middle cerebral artery was defined as a maximum length of 10 mm of the M1 segment. Primary endpoints were first-pass mTICI scores of 3, ≥2c, and ≥2b. Secondary endpoints contained final reperfusion, number of device-passes, time interval from groin puncture to reperfusion, rate of postinterventional symptomatic intracranial hemorrhage, and frequency of emboli of new territory. Results Among 284 included patients, 70 presented with an early division of the M1 segment (25%). Reperfusion results did not differ significantly between early and late division of M1. A higher rate of symptomatic intracranial hemorrhage was found in the group with an early M1 division treated with aspiration only (14.3% vs. 0%; p = 0.013). Patients with late M1 division had a significantly higher rate of large artery sclerosis (19.2% vs. 8.6%, p = 0.039). Conclusion The anatomic variant of an early division of the middle cerebral artery was not a predictor for incomplete reperfusion.

The Impact

Background: Middle cerebral artery division (M2) occlusion was significantly underrepresented in recent mechanical thrombectomy (MT) randomized controlled trials, and the approach to this disease remains heterogeneous. Objective: To conduct a systematic review and meta-analysis of outcomes at 90 days among patients undergoing MT for M2 middle cerebral artery (MCA) occlusions. Methods: Five clinical databases were searched from inception through September 2016. Observational studies reporting 90-day modified Rankin Scale scores for patients undergoing MT for M2 MCA occlusions with an M1 MCA control group were selected. The primary outcome of interest was good clinical outcome 90 days after MT of an M1 or M2 MCA occlusion. Secondary outcomes of interest included mortality and excellent clinical outcome, recanalization rates, significant intracerebral hemorrhage, and procedural complications. Results: A total of 323 publications were identified, and 237 potentially relevant articles were screened. Six studies were included in the analysis (M1 = 1,203, M2 = 258; total n = 1,461). We found no significant differences in good clinical outcomes (1.10 [95% CI, 0.83-1.44]), excellent clinical outcomes (1.07 [0.65-1.79]), mortality at 3 months (0.85 [0.58-1.24]), recanalization rates (1.06 [0.32-3.48]), and significant intracranial hemorrhage (1.19 [0.61-2.30]). Conclusions: MT of M2 MCA occlusions is as safe as that of main trunk MCA occlusions, and comparable in terms of clinical outcomes and hemorrhagic complications. Randomized clinical trials are needed to assess the impact of MT in patients with M2 occlusions, given that M1 MCA occlusions have different natural histories than M2 occlusions.

The Impact

PurposeThe impact of thrombus length on recanalization in IV thrombolysis for acute intracranial artery occlusion has been well studied. Here we analyzed the influence of thrombus length on the number of thrombectomy maneuvers needed for recanalization, intraprocedural complications, recanalization success, and clinical outcome after mechanical thrombectomy.MethodsWe retrospectively analyzed angiographic and clinical data from 72 consecutive patients with acute occlusion of the M1 segment of the middle cerebral artery who were treated with mechanical thrombectomy using stent retrievers. Successful recanalization was defined as a Thrombolysis in Cerebral Infarction score of 2b or 3. Good neurological outcome was defined as a modified Rankin Scale score of ≤2 at 90 days after stroke onset.ResultsMean thrombus length was 13.4±5.2 mm. Univariate binary logistic regression did not show an association of thrombus length with the probability of a good clinical outcome (OR 0.95, 95% CI 0.84 to 1.03, p=0.176) or successful recanalization (OR 0.92, 95% CI 0.81 to 1.05, p=0.225). There was no significant correlation between thrombus length and the number of thrombectomy maneuvers needed for recanalization (p=0.112). Furthermore, thrombus length was not correlated with the probability of intraprocedural complications (p=0.813), including embolization in a new territory (n=3).ConclusionsIn this study, thrombus length had no relevant impact on recanalization, neurological outcome, or intraprocedural complications following mechanical thrombectomy of middle cerebral artery occlusions. Therefore, mechanical thrombectomy with stent retrievers can be attempted with large clots.

Recurrent sequential mechanical thrombectomy for cryptogenic large vessel occlusion (LVO) can lead to excellent clinical outcome. A 68-year-old right-handed male presented with an acute proximal right middle cerebral artery (MCA) ischemic syndrome and underwent successful revascularization by mechanical thrombectomy with normal functional recovery. He was treated with dual antiplatelet therapy for 2 months following discharge, however later discontinued clopidogrel due to side effects. He then developed a recurrent, contralateral MCA occlusion 16 months later and once again received emergent endovascular reperfusion therapy with excellent neurological outcome. He has remained on off-label empiric oral anticoagulation since and has not had recurrent stroke nor evidence of cerebral ischemia. Favorable clinical outcomes can be achieved in patients despite recurrent LVO who underwent emergent mechanical thrombectomy. Optimal antithrombotic secondary stroke prevention strategies following embolic stroke of unknown source remains uncertain as recent evidence does not support rivaroxaban or dabigatran over aspirin. The benefit of apixaban over aspirin for the prevention of recurrent cerebral ischemia is under current investigation.

The Impact

The impact of heart failure on outcome in stroke patients is not fully understood. There is evidence for an increased mortality and morbidity, but it remains uncertain whether thrombectomy in patients with large vessel occlusion (LVO) in the anterior circulation is less effective in patients with heart failure compared to patients without. Retrospectively, we analyzed echocardiographic data of all patients in our stroke database, who underwent mechanical thrombectomy (n=668) for the presence of heart failure. Furthermore, we collected baseline characteristics and neurological and neuroradiological parameters. In the analysis, 373 of the 668 patients of our stroke database underwent echocardiography. Of these 373 patients, 90 patients (24%) suffered from heart failure with reduced left ventricular ejection fraction measured by echocardiography according to the current guidelines. After adjustment for age, the Alberta stroke program early CT score (ASPECTS), and time from symptom onset to recanalization, the analysis revealed that thrombectomy in patients with heart failure and LVO is not associated with less favorable outcome measured by the modified Rankin Scale after 90 days (3 (0-6) vs. 3 (1-5); p=0.380). Moreover, we could not find a significant difference in mortality compared to patients without heart failure (11.0% vs. 7.4%; p=0.313).
