Introduction: A common reason for non-treatment of time eligible patients with IV tPA is mild symptoms in patients that are “too good to treat (TGTT)”. Several studies have reported poor outcomes in this group. We sought to identify patient and imaging characteristics associated with poor outcomes in this group. Methods: Using our institutional GWTG database, we analyzed 2,745 consecutive stroke admissions (01/2009 - 07/2013). Univariate and multivariable analysis were carried out to determine factors associated with the poor outcome of not being discharged home. Results: Of the total 2,745 patients, 306 (11.1%) presented within the window for IV tPA but did not receive the treatment due to symptoms too mild or rapidly improving. Of these, imaging characteristics were available in 238 patients. Among TGTT stroke patients, 62.6% were discharged home, 26.9% to IRF, 8.4% to SNF and 2.1% death/hospice. Patients with poor outcome were older, more often Hispanic, with more vascular risk factors, and higher NIHSS. Infarcts in both hemispheres, and in posterior+/- anterior circulation were more common with poor outcome. On multivariable analysis, increasing age, Hispanic ethnicity, higher NIHSS and bihemispheric stroke were associated with poor outcome, with a trend toward small vessel stroke subtype. Conclusion: A substantial percentage of patients deemed “too good” for IV tPA are still unable to be discharged home. Factors such as advanced age, higher NIHSS, bi-hemispheric infarction should be considered in tPA decision-making in potential TGTT patients. Large, multi-center prospective studies are needed to better identify potential biomarkers of poor outcomes in this group.

Introduction: A common reason for exclusion of patients with acute ischemic stroke presenting within the time frame for IV tPA is that they are “too good to treat” due to rapidly improving or mild symptoms. Several studies have reported poor outcomes in this group which motivated us to evaluate patient factors associated with poor outcomes. Methods: Using our institutional GWTG database, we analyzed 2,745 consecutive stroke admissions (01/2009 - 07/2013). Univariate and multivariable analysis were carried out to determine factors associated with poor outcome, defined as not being discharged home. Results: Of the total 2,745 patients, 306 (11.1%) presented within the window for IV tPA but did not receive the treatment due to symptoms too mild or rapidly improving as judged by the treating team. Of these 306, 64.1% were discharged home, 26.5% to IRF, 7.2% to SNF and 2.9% expired/hospice. Patients with poor outcome were older, more frequently Hispanic and presented with more vascular risk factors such as hypertension, diabetes, CAD, PAD and atrial fibrillation than good outcome patients. They also had higher median initial NIHSS. Patients in both groups had similar adherence to early antithrombotics, dysphagia screening and DVT prophylaxis. Poor outcome patients had higher rates of in-hospital complications and a longer hospital length of stay (Table 1). On univariate analysis, factors associated with poor outcome included age [OR 1.50 (1.30 - 1.70), p<0.0001], ethnicity [4.15 (1.25 - 13.81), p=0.020], diabetes mellitus [1.91 (1.11 - 3.29), p=0.019], atrial fibrillation [1.82 (1.02 - 3.25), p=0.042], PAD [9.02 (1.04 - 78.20), p=0.046], NIHSS [1.16 per point (1.06 - 1.27), p=0.001], in-hospital pneumonia (all cases had poor outcome) or UTI [7.04 (1.92 - 25.81), p=0.003]. In multivariable analysis, only age [1.50 (1.30 - 1.70), p<0.0001], ethnicity [6.61 (1.83 - 23.85), p=0.004], NIHSS [1.14 per point (1.04 - 1.26), p=0.007] and UTI [7.30 (1.72 - 31.00), p=0.007] remained significant. Conclusion: A substantial percentage of patients deemed “too good” for IV tPA were unable to be discharged home. Factors such as advanced age and higher NIHSS should be considered in tPA decision-making to optimize outcomes. Large, multi-center prospective studies are underway to study the predictors of poor outcomes in this group.

The Impact

During embolectomy for acute stroke, transfemoral access to occluded vessel may be technically difficult. We aim to study the impact of difficult catheter access to target artery. Methods: Single center review of anterior circulation stroke patients enrolled in prospective trials/registries (MR Rescue, MERCI, DEFUSE) requiring recording of time from groin puncture to first device deployment(Tdep). Patients were divided according to Tdep quartiles (Q): patients in Q4 were considered as difficult access. We recorded recanalization (TICI≥2a), complete recanalization (TICI≥2b), infarct volume(24h DWI), day 5 NIHSS, and favorable outcome (3 months mRS≤2). Results: We included 196 patients, mean age 66±14, median NIHSS 16(IQR:12-21). Overall outcomes were: median Tdep 52 min (36-77), recanalization 89.1%, complete recanalization 59.4%, favorable outcome 43.8%. We observed a positive correlation between Tdep and day 5 NIHSS (r=0.27; p=0.01) or 3 months mRS (r=0.26; p<0.01). Patients with difficult access (Q4: Tdep>77 min) had similar baseline NIHSS (16 Vs 17 p=0.58), time from symptom to procedure start (433 Vs 371min; p=0.28) and occlusion location (ICA/M1/M2: 46.7/42.2/11.1% Vs 39.1/54.3/6.5%; p=0.31). However, patients in Q4 had: longer IA procedures (153 vs 112 min;p<0.01), lower complete recanalization (41% Vs 66%;p<0.01), larger infarcts (87 Vs 53cc; p<0.01), higher day 5 NIHSS (15 Vs 9;p<0.01), and less favorable outcome (29.2% Vs 49%; p=0.02). After adjusting by age and time to reperfusion, a regression model identified admission NIHSS (OR% 1.12: 95%CI 1.02-1.21; p<0.01), age (OR% 1.03: 95%CI 1.01-1.06; p=0.01) and Tdep (OR% 1.02 95%CI 1.01-1.03; p=0.01) as independent predictors of poor outcome. In univariate analysis age>69, male gender and left hemisphere stroke were associated with difficult access. The combined presence of the 3 factors increased by 3.5 fold the likelihood of difficult access (OR:3.55 95%CI 1.5-8.6: p<0.01) Conclusion: Delayed device access to target occluded artery independently predicts poor outcome. Identification of difficult access using clinical scores or imaging may lead to alternative strategies; brachial, radial or cervical approaches that could result in shortened procedural times and improved outcomes

Introduction: Distal clot migration (DCM) is a known complication of mechanical thrombectomy (MT), but neither risk factors for DCM nor ways of how it might affect clinical outcomes have been extensively studied to date. Methods: To identify risk factors for and outcomes in the setting of DCM, the records of all patients with acute ischemic stroke due to anterior circulation large vessel occlusion (LVO) treated with MT at a single center between May 2016 and June 2018 were retrospectively reviewed. Uni- and multivariable analyses were performed to evaluate predictors of DCM and good functional outcome (90-day modified Rankin Scale; mRS 0–2). Results: A total of 65 patients were included, DCM was identified in 22 patients (33.8%). Patients with DCM had significantly higher pre-procedural intravenous tissue plasminogen activator (IV-tPA) administration (81.8 vs. 53.5%, p = 0.03), stentrievers thrombectomy (95.5 vs. 62.8%, p = 0.006), and longer median puncture to recanalization time (44 [34–97] vs. 30 [20–56] min, p = 0.028) as compared to group with non-DCM. Also, they had lower rates of Thrombolysis in Cerebral Infarction (TICI) 2b/3 recanalization (p = 0.002), higher median National Institutes of Health Stroke Scale (NIHSS) scores at discharge (p = 0.01), and lower rates of 90-day mRS (0–2; 18.2 vs. 48.8%; p = 0.016). On subgroup analysis, patients with middle cerebral artery occlusions who underwent MT with stentrievers <40 mm in length had a higher risk of DCM (p = 0.026). On multivariable analysis, IV-tPA administration (OR; 5.019, 95% CI [1.319–19.102], p = 0.018) and stentrievers thrombectomy (OR; 10.031, 95% CI [1.090–92.344]; p = 0.04) remained significant predictors of DCM. Baseline NIHSS score (OR; 0.872, 95% CI [0.788–0.965], p = 0.008) and DCM (OR; 0.250, 95% CI [0.075–0.866], p = 0.03) were independent predictors of 90-day mRS 0–2. Conclusion: In patients undergoing MT for anterior circulation LVO, DCM is associated with lower rates of TICI 2b/3 recanalization and worse functional outcomes at 90 days. IV-tPA administration and MT with short stentrievers are independent predictors of DCM development.

Background- Significant numbers of acute ischemic stroke (AIS) patients recover with timely-administered intravenous tissue plasminogen activator (IV-TPA). However, rates and extent of recovery remain variable. Considering scarce and costly resources, early identification of reliable predictors for functional outcomes is important for planning rehabilitation strategies. We hypothesized that venous drainage would be impaired on the side of cerebral hypoperfusion due to acute occlusion of internal carotid or middle cerebral artery. The 2 internal cerebral veins (ICV) drain the deep parts of hemispheres and run backward to form great cerebral vein. Since ICVs are consistently seen on CT angiography (CTA), parallel and run very close to each other, even minor asymmetry in their filling can be easily diagnosed. ICV asymmetry in pre-TPA CTA can change in patients achieving arterial recanalization, rendering it less useful for predicting the long-term outcomes. Thus, we aimed at evaluating whether the presence of ICV asymmetry on follow-up CTA can predict the final outcome. Methods- Data from consecutive AIS patients treated with IV-TPA, in a standardized protocol, from Jan2007 to March2010 were included in a prospective registry at our tertiary center. In this study, we excluded posterior circulation strokes. Significant proportion AIS patients undergo CTA on day 2 after IV-TPA to assess the status of arterial patency. ICV asymmetry was assessed by 2 independent stroke neurologists/ neuroradiologists, blinded to patient data or outcomes. Functional outcomes were assessed by modified Rankin Scale (mRS) at 3-months, dichotomized as good outcome (mRS 0-1) and poor outcome (mRS 2-6). Data were analyzed for the early predictors of function outcome. Results- Of the total of 2238 patients admitted during the study period, 226 (10.1%) with anterior circulation AIS treated with intravenous thrombolysis were included. Median age was 65yrs (range 19-92), 63% males and median National Institute of Health Stroke Scale (NIHSS) 16points (range 4-32). Hypertension was the commonest vascular risk factor in 144 (76%) while 63 (33%) patients suffered from atrial fibrillation (AF). Overall, 108 (47.8%) patients achieved poor functional outcome at 3-months. ICV asymmetry could be assessed only in 103 (45.5%) patients on their follow up CTA films. Admission NIHSS score (OR1.08;95%CI 1.001-1.157,p=0.048) and ICV asymmetry on follow-up CT scan (OR 23.9;95%CI 5.15-63.99,p <0.0001) were associated with poor outcome at 3-months. Conclusion- Presence of the asymmetry of internal cerebral veins on the follow up CT angiography in acute ischemic stroke patients treated with IV-TPA can be used as an early predictor of poor functional outcome.

Background: The efficacy of endovascular therapy (EVT) in acute stroke has been established but the imaging criteria have not yet been assessed. Malignant profile is a magnetic resonance imaging (MRI) pattern that is associated with poor outcomes. We estimated this profile by volumetrically assessing diffusion weighted image (DWI) in patients treated with reperfusion therapy including intravenous tissue plasminogen activator (IV tPA) and endovascular therapy (EVT). Methods: Acute anterior ischemic stroke patients with baseline DWI before reperfusion therapy were included. Outcome was assessed by modified Rankin Scale (mRS) at discharge. DWI volume was measured by semi-automated software.Receiver operating characteristic (ROC) curve analysis was performed to identify optimal DWI volumes with poor outcome (mRS 5-6). Results: Total of 96 patients (43% women, mean age 72±13 years) were included in this study. Median (interquartile range: IQR) National Institutes of Health Stroke Scale was 9 (5-12) and median onset to MRI time was 108.5 (70-217) minutes. Median DWI volume was 4.4 (1.3-17) mL for overall patients. Median onset to IV tPA time for 60 (63%) patients were 120 (65-177) minutes. Median onset to puncture time for 36 (38%) EVT-treated patients was 208 (121.0-474.3) minutes; 29 of these 36 patients (81%) had Thrombolysis in Cerebral Infarction (TICI) score of 2B/3. Median discharge mRS was 2 (1-3) for overall and 6 cases (6%) had mRS 5-6. ROC analysis determined DWI volume with poor outcome as 49.5 mL (92.2% specificity and 50% sensitivity, AUC 0.75, p<0.001). Conclusion: Our study suggests the optimal volume of the malignant profile on DWI was approximately 50mL in reperfusion therapy eligible patients. Clinical outcome of patients exceeding the cutoff volume were very poor. The imaging criteria for reperfusion therapy including EVT should be well considered to achieve better outcomes.

Poor Outcomes

BackgroundMechanical thrombectomy with stent-retrievers results in higher recanalization rates compared with previous devices. Despite successful recanalization rates (Thrombolysis in Cerebral Infarction (TICI) score ≥2b) of 70–83%, good outcomes by 90-day modified Rankin Scale (mRS) score ≤2 are achieved in only 40–55% of patients. We evaluated predictors of poor outcomes (mRS >2) despite successful recanalization (TICI ≥2b) in the North American Solitaire Stent Retriever Acute Stroke (NASA) registry.MethodsLogistic regression was used to evaluate baseline characteristics and recanalization outcomes for association with 90-day mRS score of 0–2 (good outcome) vs 3–6 (poor outcome). Univariate tests were carried out for all factors. A multivariable model was developed based on backwards selection from the factors with at least marginal significance (p≤0.10) on univariate analysis with the retention criterion set at p≤0.05. The model was refit to minimize the number of cases excluded because of missing covariate values; the c-statistic was a measure of predictive power.ResultsOf 354 patients, 256 (72.3%) were recanalized successfully. Based on 234 recanalized patients evaluated for 90-day mRS score, 116 (49.6%) had poor outcomes. Univariate analysis identified an increased risk of poor outcome for age ≥80 years, occlusion site of internal carotid artery (ICA)/basilar artery, National Institute of Health Stroke Scale (NIHSS) score ≥18, history of diabetes mellitus, TICI 2b, use of rescue therapy, not using a balloon-guided catheter or intravenous tissue plasminogen activator (IV t-PA), and >30 min to recanalization (p≤0.05). In multivariable analysis, age ≥80 years, occlusion site ICA/basilar, initial NIHSS score ≥18, diabetes, absence of IV t-PA, ≥3 passes, and use of rescue therapy were significant independent predictors of poor 90-day outcome in a model with good predictive power (c-index=0.80).ConclusionsAge, occlusion site, high NIHSS, diabetes, no IV t-PA, ≥3 passes, and use of rescue therapy are associated with poor 90-day outcome despite successful recanalization.

BackgroundElevated mean platelet volume (MPV), indicating higher platelet activity, could be a predictor of prognosis in patients with acute ischemic stroke receiving medical therapy.ObjectiveTo investigate the relationship between MPV and functional outcome in patients with acute anterior circulation stroke 3 months after undergoing mechanical thrombectomy (MT).MethodsA total of 153 consecutive patients with acute stroke following MT, in two separate stroke centers, were enrolled between May 2013 and March 2016. MPV was measured on admission. Subjects were divided into two groups according to average MPV level. Univariate and multivariate analyses were performed. MPV was also incorporated into the Houston IA Therapy (HIAT) score, which was developed as a scoring system to predict poor prognosis, and the prediction capability was compared with the HIAT score alone.ResultsThe average MPV was 10.4 fL. Patients with high MPV had a significantly lower rate of functional independence (28.9% vs 57.1%, p=0.000). After multivariable analysis, elevated MPV remained an independent predictor of unfavorable outcome (OR=3.93, 95% CI 1.73 to 8.94, p=0.001). When the MPV cut-off value was set at 10.4 fL using the receiver operating characteristic (ROC) analysis, MPV ≥10.4 fL predicted unfavorable outcome with 62.1% sensitivity and 66.7% specificity, respectively. Addition of MPV to the HIAT score did not improve predictive power compared with the HIAT score system alone by a comparison of the areas under the two ROC curves (0.70 vs 0.62, p=0.174).ConclusionsElevated MPV is an independent predictor of poor outcome in patients with acute anterior circulation stroke undergoing MT at 3 months.

Background: Several methods exist that assess the intracranial collaterals on CT-angiography (CTA) of the brain. We compared existing methods for quantification of collaterals on day-2 CTA in thrombolyzed AIS patients to assess their predictive value for functional outcome. Methods: Consecutive AIS patients treated with intravenous tissue plasminogen activator (IV-tPA) during 2007-2012 were included. Data were collected for demographics, vascular risk factors, NIHSS scores and stroke subtypes. Intracranial collaterals were evaluated by 2 independent neuroradiologists using 4 existing methods- Miteff’s system (grades middle cerebral artery (MCA) collateral branches with respect to sylvian fissure); Maas system (compares collaterals in affected hemisphere against the contralateral side); Modified Tan’s scale (collaterals in 50% or more of MCA territory classified as good); and 20-point collateral grading scale by Alberta Stroke Program Early CT score (ASPECTS) methodology. Good functional outcome at 3-months was determined by modified Rankin scale (mRS) scores of 0-1. Results: Day-2 CTA was performed in 150 patients with anterior circulation AIS treated with IV-tPA. Median age 66yrs (range 33-92), 47% males, median NIHSS 19 points (range 4-34) and median onset-to-treatment time 165 minutes (range 74-274). Overall, 67 (44.6%) patients achieved good functional outcome at 3-months. On univariable analysis- younger age, lower pre-tPA NIHSS scores, atrial fibrillation, good collaterals according to ASPECTS scoring and good collaterals by Maas methodology were significantly associated with good functional outcome. On multivariable analysis, lower NIHSS (OR 1.155 per NIHSS point; 95% CI 1.066-1.251, p=0.001), younger age (OR 1.052 per year; 95% CI 1.012-1.094, p=0.010), good collaterals by Maas methodology (OR 2.805 95% CI 1.122 -7.011, p =0.002) and good collaterals (score of 9 or more) by ASPECTS methodology (OR 3.769 ; 95%CI: 1.327- 10.708, p= 0.013 ) were found as independent predictors of good outcome. Conclusion: Of the existing intracranial collaterals scoring systems, only the ASPECTS and Maas methods are reliable predictor of favourable outcome in thrombolyzed anterior circulation AIS patients.

Objective: With the aging of the world population, the number of elderly patients suffering from aneurysmal subarachnoid hemorrhage (aSAH) is gradually growing. We aim to investigate the potential association between plasma ALT level and clinical complications of elderly aSAH patients, and explore its predictive value for clinical outcomes of elderly aSAH patients. Methods: Between January 2013 and March 2018, 152 elderly aSAH patients were analyzed in this study. Clinical information, imaging findings and laboratory data were reviewed. According to the Glasgow Outcome Scale (GOS), clinical outcomes at 3 months were classified into favorable outcomes (GOS 4-5) and poor outcomes (GOS 1-3). Logistic regression analysis was used to assess the indicators associated with poor outcomes, and receiver curves (ROC) and corresponding area under the curve (AUC) were used to detect the accuracy of the indicator. Results: A total of 48 (31.6 %) elderly patients with aSAH had poor outcome at 3 months. In addition to ICH, IVH, Hunt-Hess 4 or 5 Grade and Modified Fisher 3 or 4 Grade, plasma ALT level was also strongly associated with poor outcome of elderly aSAH patients. After adjusting for other covariates, plasma ALT level remained independently associated with pulmonary infection (OR 1.05; 95% CI 1.00–1.09; P = 0.018), cardiac complications (OR 1.05; 95% CI 1.01–1.08; P = 0.014) and urinary infection (OR 1.04; 95% CI 1.00–1.08; P = 0.032). Besides, plasma ALT level had a predictive ability in the occurrence of systemic complications (AUC 0.676; 95% CI: 0.586– 0.766; P<0.001) and poor outcome (AUC 0.689; 95% CI: 0.605–0.773; P<0.001) in elderly aSAH patients. Conclusion: Plasma ALT level of elderly patients with aSAH was significantly associated with systemic complications, and had additional clinical value in predicting outcomes. Given that plasma ALT levels on admission could help to identify high-risk elderly patients with aSAH, these findings are of clinical relevance.

Introduction: The role of neuroinflammation following aneurysmal subarachnoid hemorrhage (SAH) and its relationship to outcome is the subject of many ongoing studies. The proteolytic enzyme, caspase-1, activated by the inflammasome complex, is known to contribute to numerous downstream pro-inflammatory effects. In this study, we investigated caspase-1 activity in the cerebrospinal fluid (CSF) of SAH patients and its association to outcome. Methods: SAH patients were recruited from a regional stroke referral center. CSF samples from 18 SAH subjects were collected via an external ventricular drain and obtained within 72 hours of the onset of symptoms. For control subjects, we collected the CSF from 9 patients undergoing lumbar puncture with normal CSF and normal brain MRI. Caspase-1 activity was measured using commercially available luminescence assays. SAH subjects were categorized at hospital discharge into those with good outcomes (Glasgow Outcome Scale, GOS, of 4-5) and poor outcomes (GOS of 1-3). The levels of caspase-1 activity in various groups were analyzed using Mann-Whitney and Pearson correlation tests. Caspase-1 activity was also adjusted by initial severity of bleed using analysis of covariance (ANCOVA). Results: Caspase-1 levels from SAH patients were significantly higher than that measured from the control group (mean 1.06x10-2 vs 1.90x10-3 counts per second (CPS)/μl*min), p = 0.0002). Within the SAH group, 10 patients (55.6%) had good outcomes and 8 patients (44.4%) had poor outcomes. Caspase-1 activity was significantly higher in the poor outcome group (mean 1.54x10-2 vs 1.60x10-3 CPS/μl*min), p = 0.0012). Additionally, caspase-1 activity had a statistically significant correlation with GOS score (r = -0.60; p = 0.0100). When adjusted for initial severity of bleed, the difference in caspase-1 activity in good vs. poor outcome remained significant (adjusted mean 7.10x10-3 vs. 2.54x10-2 CPS/μl*min, p=0.004). Conclusions: The inflammasome-dependent protein caspase-1 is elevated in CSF early after SAH and higher in those with poor functional outcome. Inflammasome activity therefore may serve as a novel biomarker to predict outcome shortly after aneurysm rupture.
