Arterial Recanalization

Introduction: Futile arterial recanalization (FAR), considered as a lack of functional recovery despite complete recanalization, is observed in up to 30-50% of acute stroke patients treated with endovascular therapy. We aimed to develop a prognostic scale based on baseline clinical and radiological factors to predict FAR. Methods: Prospective analysis of consecutive stroke patients with anterior circulation occlusion treated with endovascular therapy (97% mechanical thrombectomy with stent-retrievers). Complete recanalization was considered as a TICI 2b-3. FAR was defined as a modified Rankin scale >2 at 90 days in patients with complete recanalization. Baseline factors associated with FAR were detected on univariate analysis and were used to compose the predictive scale. Results: From a total of 229 patients with anterior arterial occlusion, 166 (72.5%) achieved complete recanalization. FAR was observed in 80/166 (48.2%). Factors significantly associated with FAR were included to compose the predictive scale as follow: Age (scoring 0 if ≤70 and 1 if >70 years old), history of diabetes mellitus (0 if absent, 1 if present), history of hypertension (0 if absent, 1 if present), NIHSS (1 if NIHSS ≤10, 2 if NIHSS 10-19, 3 if NIHSS>19), ASPECTS (1 if ASPECTS 9-10, 2 if ASPECTS 7-8, 3 if ASPECTS<7) and i.v tPA use (0 if yes, 1 if not). The higher the scale score, the higher the risk of FAR (Figure). The scale showed a good predictive value of FAR (c-statistics 0.71). A scale score <5 was associated with a low rate of FAR (25%) whereas a score >7 increased FAR up to 86%. Conclusion: We developed a simple scale that can easily predict futile arterial recanalization (FAR) in stroke patients with large arterial occlusion treated with endovascular therapies. A larger validation study is necessary to confirm the utility of this predictive scale.

BackgroundIt has been reported that longer time intervals from stroke onset to endovascular therapy are associated with lower rates of successful reperfusion in acute ischemic stroke patients with large vessel occlusion. However, procedural variables and potential mechanisms of this association have not been fully elucidated.MethodsWe performed a secondary analysis of individual patient data from the North American Solitaire Stent Retriever Acute Stroke (NASA) and Trevo Stent-Retriever Acute Stroke (TRACK) registries. We included patients with occlusion of the internal carotid artery or middle cerebral artery (M1 and M2 segments) who were treated by mechanical thrombectomy within 24 hours of last known normal. The primary outcome was reperfusion, defined as a Thrombolysis In Cerebral Infarction (TICI) score ≥2b. The secondary outcome was reperfusion on the first pass. The primary predictor was duration of symptomatic stroke, defined as time from last known normal to time of final pass. Adjusted logistic regression models were utilized to determine associations between variables and outcome.ResultsWe included 506 patients, of which 401 (79.3%) achieved successful reperfusion (TICI 2b/3). The mean (SD) duration of symptomatic stroke was 6.8 (3.5) hours and in the adjusted logistic regression model the duration of symptomatic stroke was associated with reperfusion (OR 0.90, 95% CI 0.84 to 0.96) and reperfusion on the first pass (OR 0.89, 95% CI 0.83 to 0.95). In that model, the predicted probability of reperfusion was 88% (95% CI 0.83 to 0.92) at 1 hour, 81% (95% CI 0.78 to 0.84) at 6 hours, 70% (95% CI 0.63 to 0.77) at 12 hours, and 42% (95% CI 0.17 to 0.67) at 24 hours (ptrend=0.001). Reperfused patients were significantly younger, more likely to be male, and to have had a balloon guide catheter used during the procedure.ConclusionIn a real-world cohort of acute ischemic stroke patients with anterior circulation occlusion treated with endovascular therapy, longer duration of symptomatic stroke is associated with lower rates of successful reperfusion and reperfusion on the first pass.

Abstract Purpose Mechanical thrombectomy (MT) is the first-line treatment in acute stroke patients presenting with large vessel occlusion (LVO). The efficacy of intravenous thrombolysis (IVT) prior to MT is being contested. The objective of this study was to evaluate the efficacy of MT without IVT in patients with no contraindications to IVT presenting directly to a tertiary stroke center with acute anterior circulation LVO. Materials and Methods We collected the data of 106 acute stroke patients who underwent MT in a single high-volume stroke center. Patients with anterior circulation LVO eligible for IVT and directly admitted to our institution who subsequently underwent MT were included. We recorded baseline clinical, laboratory, procedural, and imaging variables and technical, imaging, and clinical outcomes. The effect of intravenous thrombolysis on 3-month clinical outcome (mRS) was analyzed with univariate tests and binary and ordinal logistic regression analysis. Results Fifty-eight out of the 106 patients received IVT + MT. These patients had 2.6-fold higher odds of poorer clinical outcome in mRS shift analysis (p = 0.01) compared to MT-only patients who had excellent 3-month clinical outcome (mRS 0–1) three times more often (p = 0.009). There were no significant differences between the groups in process times, mTICI, or number of hemorrhagic complications. A trend of less distal embolization and higher number of device passes was observed among the MT-only patients. Conclusions MT without prior IVT was associated with an improved overall three-month clinical outcome in acute anterior circulation LVO patients.

BackgroundThe benefit of complete reperfusion (modified Thrombolysis in Cerebral Infarction (mTICI) 3) over near-complete reperfusion (≥90%, mTICI 2c) remains unclear. The goal of this study is to compare clinical outcomes between mechanical thrombectomy (MT)-treated stroke patients with mTICI 2c versus 3.MethodsThis is a retrospective study from the Stroke Thrombectomy and Aneurysm Registry (STAR) comprising 33 centers. Adults with anterior circulation arterial vessel occlusion who underwent MT yielding mTICI 2c or mTICI 3 reperfusion were included. Patients were categorized based on reperfusion grade achieved. Primary outcome was modified Rankin Scale (mRS) 0–2 at 90 days. Secondary outcomes were mRS scores at discharge and 90 days, National Institutes of Health Stroke Scale score at discharge, procedure-related complications, and symptomatic intracerebral hemorrhage.ResultsThe unmatched mTICI 2c and mTICI 3 cohorts comprised 519 and 1923 patients, respectively. There was no difference in primary (42.4% vs 45.1%; p=0.264) or secondary outcomes between the unmatched cohorts. Reperfusion status (mTICI 2c vs 3) was also not predictive of the primary outcome in non-imputed and imputed multivariable models. The matched cohorts each comprised 191 patients. Primary (39.8% vs 47.6%; p=0.122) and secondary outcomes were also similar between the matched cohorts, except the 90-day mRS which was lower in the matched mTICI 3 cohort (p=0.049). There were increased odds of the primary outcome with mTICI 3 in patients with baseline mRS ≥2 (36% vs 7.7%; p=0.011; pinteraction=0.014) and a history of stroke (42.3% vs 15.4%; p=0.027; pinteraction=0.041).ConclusionsComplete and near-complete reperfusion after MT appear to confer comparable outcomes in patients with acute stroke.

<b><i>Objective:</i></b> The frequency of seizures after stroke is high, with a severe impact on the quality of life. However, little is known about their prevention. Therefore, we investigated whether early administration of diazepam prevents the development of seizures in acute stroke patients. <b><i>Methods:</i></b> We performed a substudy of the EGASIS trial, a multicenter double-blind, randomized trial in which acute stroke patients were treated with diazepam or placebo for 3 days. Follow-up was after 2 weeks and 3 months. The occurrence of seizures was registered prospectively as one of the prespecified secondary outcomes. <b><i>Results:</i></b> 784 EGASIS patients were eligible for this substudy (389 treated with diazepam [49.6%] and 395 treated with placebo [50.4%]). Seizures were reported in 19 patients (2.4% of the total patient group). Seizures occurred less frequently in patients treated with diazepam (1.5 vs. 3.3% in the placebo group); however, this difference was only statistically significant in patients with a cortical anterior circulation infarction (0.9% in the diazepam group vs. 4.6% in the placebo group, incidence rate ratio 0.20, 95% CI: 0.05–0.78, <i>p</i> = 0.02, NNT = 27). <b><i>Conclusion:</i></b> We found that a 3-day treatment with diazepam after acute cortical anterior circulation stroke prevents the occurrence of seizures in the first 3 months following stroke.

Background: Recanalization of the occluded artery is a powerful predictor of good outcome in acute ischemic stroke secondary to large artery occlusions. Mechanical thrombectomy with stent-trievers results in higher recanalization rates and better outcomes compared to previous devices. However, despite successful recanalization rates (Treatment in Cerebral Infarction, TICI, score ≥ 2b) between 70 and 90%, good clinical outcomes assessed by modified Rankin Scale (mRS) ≤ 2 is present in 40-50% of patients . We aimed to evaluate predictors of poor outcomes (mRS > 2) despite successful recanalization (TICI ≥ 2b) in the acute stroke patients treated with the Solitaire device of the North American Solitaire Stent Retriever Acute Stroke (NASA) registry. Methods: The NASA registry is a multicenter, non-sponsored, physician-conducted, post-marketing registry on the use of SOLITAIRE FR device in 354 acute, large vessel, ischemic stroke patients. Logistic regression was used to evaluate patient characteristics and treatment parameters for association with 90-day mRS score of 0-2 (good outcome) versus 3-6 (poor outcome) within patients who were recanalized successfully (Thrombolysis in Cerebral Infarction or TICI score 2b-3). Univariate tests were followed by development of a multivariable model based on stepwise selection with entry and retention criteria of p < 0.05 from the set of factors with at least marginal significance (p ≤ 0.10) on univariate analysis. The c-statistic was calculated as a measure of predictive power. Results: Out of 354 patients, 256 (72.3%) were successfully recanalized (TICI ≥ 2b). Based on 90-day mRS score for 234 of these patients, there were 116 (49.6%) with mRS > 2. Univariate analysis identified increased risk of mRS > 2 for each of the following: age ≥ 80 years (upper quartile of data), occlusion site other than M1/M2, NIH Stroke Scale (NIHSS) score ≥ 18 (median), history of diabetes mellitus (DM), TICI = 2b, use of rescue therapy, not using a balloon-guided catheter (BGC) or intravenous tissue plasminogen activator (IV t-PA), and time to recanalization > 30 minutes (all p ≤ 0.05). Three or more passes was marginally significant (p=0.097). In multivariable analysis, age ≥ 80 years, site other than M1/M2, initial NIHSS ≥18, DM, absence of IV t-PA, use of rescue therapy and three or more passes were significant independent predictors of poor 90-day outcome in a model with good predictive power (c-index = 0.80). Conclusions: Age, occlusion site, high NIHSS, diabetes, not receiving IV t-PA, use of rescue therapy and three or more passes, were associated with poor 90-day outcome despite successful recanalization.

Background: The degree of variability in the rate of early DWI expansion has not been well characterized. We hypothesized that Target Mismatch patients with slowly expanding DWI lesions have more penumbral salvage and better clinical outcomes following endovascular reperfusion than Target Mismatch patients with rapidly expanding DWI lesions. Methods: This substudy of DEFUSE 2 included all patients with a clearly established time of symptom onset. The initial DWI growth rate was determined from the baseline scan by assuming a volume 0 ml just prior to symptom onset. Target Mismatch patients who achieved reperfusion (>50% reduction in PWI after endovascular therapy), were categorized into tertiles according to their initial DWI growth rates. For each tertile, penumbral salvage (comparison of final volume to the volume of PWI (Tmax > 6 sec)/ DWI mismatch prior to endovascular therapy), favorable clinical response, and good functional outcome (see figure for definitions) were calculated. We also compared the growth rate in patients with the Target mismatch vs. Malignant Profile. Results: 64 patients were eligible for this study. Target mismatch patients (n=44) had initial growth rates (range 0 to 43 ml/hr, median of 3 ml/hr) that were significantly less than the growth rates in Malignant profile (n=7) patients (12 to 92 ml/hr, median 39 ml/hr; p < 0.001). In Target mismatch patients who achieved reperfusion (n=30), slower early DWI growth rates were associated with better clinical outcomes (p<0.05) and a trend toward more penumbral salvage (n=27, p=0.137). Conclusions: The growth rate of early DWI lesions in acute stroke patients is highly variable; Malignant profile patients have higher growth rates than other MRI profiles. Among Target Mismatch patients, a slower rate of DWI growth is associated with a greater degree of penumbral salvage and improved clinical outcomes following endovascular reperfusion.

Arterial Recanalization

Background: Data on arterial recanalization after IV t-PA treatment are rare. IMS-3 allows the study of variables affecting arterial recanalization after IV t-PA in acute ischemic stroke patients with CTA-proved major artery occlusions. Methods: Of 656 acute ischemic stroke patients in IMS-3, 306 were examined with baseline CTA and randomized either to IV t-PA (N=95) or to IV t-PA followed by digital subtraction angiography (DSA) and endovascular therapy (EVT) (N=211). Comparison of baseline CTA to DSA within 5 hours of stroke onset assessed early arterial recanalization after IV t-PA. A central core lab categorized DSA vessel occlusion as “no, partial, or complete”. We studied the association between arterial occlusion sites on baseline CTA with early recanalization for the endovascular group and analyzed its impact on clinical outcome at 90 days. Results: In the EVT group, 22 patients (10.4%) had no CTA intracranial occlusions, but 1 extracranial occlusion; 42 patients (19.9%) had occlusions of intracranial internal carotid artery (ic-ICA); 10 patients (4.7%) had tandem occlusions of the cervical ICA and middle cerebral artery (MCA); 95 patients (45.0%) had MCA-trunk (M1) occlusions, 33 patients (15.6%) had M2 occlusions, 3 patients (1.4%) had M3/4 occlusions, and 6 patients (2.8%) occlusions within posterior circulation. Partial or complete recanalization occurred in 28.6% of patients before DSA and was marginally associated with occlusion site (p=0.0525) (8 patients (19.0%) with ic-ICA occlusion, 0 patients with tandem ICA/MCA occlusions, 34 patients (35.8%) with M1 occlusions, 11 patients (33.3%) with M2 occlusions, 0 patients with M3/4 occlusions, and 1 patient (16.7%) with occlusion within posterior circulation). Three CTA negative patients had intracranial occlusions on DSA. Thirty-two patients (59.3%) with early recanalization achieved mRS of 0-2 at 90 days compared to 51 patients (38.4%) without early recanalization (p=0.0099). There was no relationship between early recanalization and time to IV t-PA or mean t-PA dose. Conclusion: Before EVT, IV rt-PA may facilitate arterial recanalization and better clinical outcome in about one third of patients.

The Impact

Background: Risk factors for stroke may alter hemodynamics or invoke ischemic preconditioning, yet the impact of such factors on response to acute stroke treatment and the potential relationship with collateral circulation remains unknown. Methods: Consecutive cases enrolled in the International Multicenter Registry for Mechanical Recanalization Procedures in Acute Stroke (ENDOSTROKE) were analyzed with respect to collateral status on baseline angiography before endovascular therapy. ASITN/SIR collateral grade (0-1/2/3-4) was scored by the core lab, blind to all other data. Collateral grade was analyzed with respect to numerous baseline risk factors, demographics and outcomes after endovascular intervention. Results: 109 patients (median age 69 years (25 th , 75 th percentiles: 56, 77); 51% women; median baseline NIHSS 15 (13, 18)) with complete (TICI 0) anterior circulation occlusions (M1, n=71; ICA, n=28; M2, n=10) at baseline were evaluated based on collateral grade (0-1, n=12; 2, n=41; 3-4, n=56). Worse collaterals were noted in patients with atrial fibrillation (ASITN grades 0-1/2/3-4: 21%/30%/49%) as compared to patients without atrial fibrillation (5%/42%/53%, p=0.024), yet cardioembolic stroke etiology was unrelated. Other baseline features such as age, gender, time to presentation, other co-morbidities and labs were unrelated to collateral grade. Post-procedure reperfusion (TICI 2b-3) was significantly associated with better collaterals (OR 2.58 (1.343-4.957, p=0.004). Similarly, final infarct size was significantly smaller in those with better collaterals. Good clinical outcomes (mRS 0-2 at day 90) were less frequent in those with poorer collaterals (OR 0.403 (0.199-0.813, p=0.011). Conclusions: Atrial fibrillation, but not cardioembolic stroke etiology, is associated with worse collaterals. Hemodynamic implications, such as diminished cardiac output due to atrial fibrillation, may result in less favorable outcomes after endovascular therapy for acute stroke.

Objectives: Animal models have shown that the spleen contracts and contributes to post-ischemic inflammation that may exacerbate brain injury and impair recovery. Translation of these findings in patients is challenging because of a lack of normative spleen volume (SV) data. We created normograms of SV for an adult at-risk population, quantified splenic contraction (SC) in stroke patients, and characterized patients with SC. Methods: We enrolled 158 healthy volunteers (HV) with matching age and gender distribution with that of our stroke center registry. Spleen ultrasounds were performed on 5 consecutive days. We used quantile regression models to identify predictors of SV for HV. Gender and body surface area (BSA) were used to construct percentile based normograms of SV, and the expected pre-stroke SV were calculated, from which SC was quantified. We also enrolled a cohort of 170 patients with acute stroke and intracerebral hemorrhage within 24 hours of symptom onset and performed serial spleen ultrasound measurements during hospitalization. Logistic regression was used to determine factors associated with SC. Results: Normograms for SV in healthy males and females based on BSA were created (Figure 1). Over a 5-day consecutive period of daily spleen measurements, the maximum day to day variation was 10.6 cm3. Based on these findings, stroke patients with a normalized SV below 20 cm3 of their expected SV, were classified as having SC. Excluding stroke mimics, 158 patients were included in the analyses, of which 64 (40.5%) had SC detected within 24 hrs of symptom onset. African-American race, older age, and history of previous stroke were significantly associated with SC (Table 1). Conclusion: The spleen does appear to reduce in size after stroke in some specific subgroups of patients with acute stroke and brain hemorrhage. The biological relevance of SC to the inflammatory response and functional outcomes of stroke patients are currently being studied in our study cohorts.
