Background and Purpose— The treatment and prognosis of acute large vessel occlusion with mild symptoms have not been sufficiently studied. The present study aimed to investigate the clinical or radiological predictors of clinical outcome in patients with stroke with mild symptoms due to acute large vessel occlusion. Methods— Of 2420 patients with acute large vessel occlusion in the RESCUE-Japan Registry 2 (Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism-Japan Registry 2), a multicenter prospective registry in Japan, patients with modified Rankin Scale scores of 0 to 2 before onset and initial National Institutes of Health Stroke Scale (NIHSS) scores of 0 to 5 were examined in post hoc analysis. We examined the clinical and radiological characteristics associated with a favorable outcome (modified Rankin Scale score, 0–2 at 90 days) using multivariate analysis, as well as the factors associated with a favorable outcome in patients treated with endovascular therapy. Results— We analyzed 272 patients (median age, 73 years; median NIHSS score on admission, 3). Eighty-six (31.6%) patients were treated with intravenous recombinant tissue-type plasminogen activator, 54 (19.9%) underwent endovascular therapy, and 208 (76.5%) showed a favorable outcome. In multivariate analysis, age <75 years (odds ratio [OR], 2.42 [95% CI, 1.30–4.50]), initial NIHSS score 0 to 3 (OR, 3.08 [95% CI, 1.59–5.98]), intravenous recombinant tissue-type plasminogen activator (OR, 2. 86 [95% CI, 1.32–6.21]), and blood glucose level ≤140 mg/dL (OR, 2.37 [95% CI, 1.22–4.60]) were independently associated with a favorable outcome. However, endovascular therapy was not associated with a favorable outcome (OR, 1.65 [95% CI, 0.71–3.88]). Among 54 patients treated with endovascular therapy, good reperfusion status was more common in the favorable outcome group (88.6% versus 60.0%; P <0.05). Conclusions— Younger age, lower initial NIHSS score, intravenous recombinant tissue-type plasminogen activator, and absence of hyperglycemia were independently associated with a favorable outcome in patients with acute large vessel occlusion with low NIHSS scores.

Background: Large vessel occlusions with a high clot burden are less likely to improve with the FDA-approved IV strategy. Endovascular therapy within the first 3 h of stroke symptom onset provides an effective alternative treatment in patients with large vessel occlusion. It is not clear if combination of IV thrombolysis and endovascular approach is superior to endovascular treatment alone. Methods: We retrospectively reviewed all cases of acute ischemic stroke with large vessel occlusion treated within the first 3 h stroke onset during the 2005-2010 period. First group received endovascular therapy within the first 3 h of stroke onset. Second group consisted of patients who received IV thrombolysis within the first 3 h followed by endovascular therapy. We compared the following outcomes: revascularization rates, NIHSS score at discharge, mRS at discharge and 3months, symptomatic hemorrhage rates and mortality. Results: Among 104 patients identified, 42 received combined therapy, and 62 received endovascular therapy only. The two groups had similar demographic (age and sex distribution) and vascular risk factors distribution, as well as NIHSS score on admission (14.8±4.7 and 16.0±5.3; p=0.23). We found no difference in TIMI recanalization rates (Thrombolysis in Myocardial Infarction scale score of 2 or 3) following combined or endovascular therapy alone (83.3% and 79.0%; p=0.59). A preferred outcome, defined as a mRS of 2 or less at 90 days also did not differ between the combined therapy group and the endovascular only group (37.5% and 34.5%; p=0.76). There was no difference in mortality rate (22.5% and 31.0%; p=0.36) and the rate of symptomatic intracranial hemorrhage (9.5% and 8.1%; p=0.73). There was a significant difference in mean time from symptom onset to endovascular treatment between the combined group (227±88 min) and endovascular only group (125±40 min; p<0.0001).Patients with good TIMI recanalization rate of 2 or 3 showed a trend of having a better mRS at 90 days in both bridging (16.67% vs. 41.18%, p-value: 0.3813) and endovascular groups (25% vs. 34.78%, p-value: 0.7326).When analyzing the correlation of mRS at 90 days with the site of occlusion, patients in the bridging group showed a trend of a better outcome when the site of occlusion was ICA (33.3% vs 30%) and MCA (66.67% vs. 27.59%) and worse outcome when the site of occlusion was in the posterior circulation (26.32% vs. 50%), however, these results were not statistically significant (p-values: 0.1735& 0.5366). Conclusion: Combining IV thrombolysis and endovascular therapy achieves similar rates of clinical outcomes, revascularization rates, complications and mortality rates, when compared with endovascular treatment alone. The combined therapy, however, significantly delays initiation of endovascular treatment. A randomized prospective trial comparing both treatment strategies in acute ischemic stroke is warranted

Background and purpose Large vessel occlusion (LVO) in acute ischemic stroke has been reported to be an independent predictor of unfavorable clinical outcome. However, the prognosis and optimal treatment of patients with only mild neurologic deficits due to LVO are not known. Methods We performed a retrospective chart review from a database of stroke patients admitted to our large academic medical center between July 1, 2010 and June 30 , 2011. Inclusion criteria were acute stroke or TIA, presentation within 9 hours from symptom onset, large vessel occlusion as a culprit of ischemic symptoms, and mild stroke severity with initial NIH Stroke Scale (NIHSS) score <8. Results We identified 59 patients with mild ischemic stroke or TIA, who were evaluated within 9 hours from onset. Of these, 13 (22%) had culprit large vessel occlusions. Five were female, 1 had diabetes, 12 had hypertension, 7 had hyperlipidemia, 2 had atrial fibrillation and 7 were smokers. The median NIHSS score was 5. The location of arterial occlusions were 5 in M1 segment of the middle cerebral artery (MCA), 6 in M2 segment of MCA, 1 each in posterior cerebral and vertebral arteries. Two patients received acute therapy, 1 with intravenous thrombolysis and 1 with endovascular therapy. Reasons for withholding thrombolytic therapy were time window in 8, mild stroke severity in 2, and atypical presentations in 2. Reasons for withholding acute endovascular therapy were mild stroke severity in 7, imaging finding in 2, technical considerations in 2, and lack of consent in 1. From hospital admission to discharge, 10 (77%) patients had symptom improvement, 2 had worsening, and one was unchanged. At 30 days, 5 (38%) had good outcome with a modified Rankin Scale (mRS) of 0-1. Three (23%) had mRS of 2, one (8%) patient had mRS of 3. Outcomes for 4 patients were unknown. Conclusions A significant proportion of patients presenting with mild ischemic symptoms has large vessel occlusion. Acute treatment in this population is frequently withheld due to mild severity or thrombolytic time window. Despite mild symptoms at presentation, some patients are left with moderate disability. Optimal treatment options for this population should be further evaluated in a larger group of patients.

IntroductionIt remains unclear whether patients presenting with large vessel occlusion strokes and mild symptoms benefit from thrombectomy.ObjectiveTo compare outcomes of endovascular therapy versus medical management in patients with large vessel occlusion strokes and National Institute of Health Stroke Scale (NIHSS) score ≤5.MethodsThis was a retrospective analysis combining two large prospectively collected datasets including patients with (1) admission NIHSS score ≤5, (2) premorbid modified Rankin Scale (mRS) score 0–2, and (3) middle cerebral-M1/M2, intracranial carotid, anterior cerebral or basilar artery occlusions. Groups receiving (1) endovascular treatment and (2) medical management were compared. The primary and secondary outcome measures were NIHSS shift (discharge NIHSS minus admission NIHSS) and the rates of mRS 0–2 at discharge and 3–6 months, respectively. Univariate, multivariate, and matched analyses were performed.ResultsEighty-eight patients received medical management and 30 thrombectomy. Multivariable analysis indicated thrombectomy was the only predictor of favorable NIHSS shift (β −3.7, 95% CI −6.0 to −1.5, p=0.02), as well as independence at discharge (β −21.995% CI −41.4to −20.8, p<0.01) and 3–6-month follow-up (β −21.1, 95% CI −39.1 to −19.7, p<0.01). A matched analysis (based on age, baseline NIHSS and intravenous tissue plasminogen activator use) produced 26 pairs. Endovascular therapy was statistically associated with lower NIHSS at discharge (p=0.04), favorable NIHSS shift (p=0.03), and increased independence rates at discharge (p=0.03) and 3–6-month follow-up (p=0.04).ConclusionIn patients presenting with minimal stroke symptoms (NIHSS score ≤5) and large vessel occlusion strokes, mechanical thrombectomy appears to be associated with a favorable shift of NIHSS at discharge, as well as higher rates of independence at discharge and long-term follow-up. Confirmatory prospective studies are warranted.

Background: Cerebral infarction is usually due to arterial occlusion. Prompt treatment with thrombolytic drugs can restore blood flow and improve recovery from an infarct. Purpose: To evaluate the clinical efficacy and safety of local intraarterial thrombolysis with recombinant tissue-type plasminogen activator (rtPA) in patients with acute middle cerebral artery (MCA) infarctions within 6 hours of the onset of symptoms. Material and Methods: Sixteen patients (10 females and six males) aged from 42 to 61 years, with acute MCA territory infarcts were selected for treatment with local i.a. rtPA up to 6 hours after the onset of symptoms. Patient selection was based on clinical examination, computed tomography (CT), and digital subtraction angiography (DSA). A clinical evaluation was performed before treatment, at the time of discharge, and 90 days post-procedure on the basis of modified Rankin and NIHSS scores. Controls ( n = 16, nine females and seven males) aged from 51 to 70 years were treated only with intravenous anticoagulation using i.v. heparin infusion. The control group was evaluated with multidetector CT (MDCT) angiography performed on entry to the study and at 2–4 hours afterwards. Results: Eight patients (50%) achieved a modified Rankin score of 2 or less as the primary outcome after 90 days follow-up. The secondary clinical outcome at 90-day follow-up was as follows: NIHSS score ⩽1, three (19%) of the patients; NIHSS score ⩾50% decrease, nine (56%) of the patients. A recanalization rate of 75% was achieved in 12 of the 16 treated patients, but only 12.5% in two of the 16 patients in the control group. Intracerebral hemorrhage occurred in two (12.5%) of the patients in the treatment group, but in only one patient (6%) in the control group. There were no deaths in the treated group after thrombolysis up to the time of discharge; however, during the 90-day follow-up, two patients died compared to three patients in the control group (19% vs. 12.5% mortality rate). Conclusion: Patients with cerebral infarction who were treated within 6 hours of onset using intraarterial rtPA thrombolysis had a significantly improved clinical outcome 90 days after the procedure compared to patients treated only with intravenous anticoagulation.
