Object Endovascular treatment of acute ischemic stroke delivers direct therapy at the site of an occluded cerebral artery and can be employed beyond the 3–4.5-hour window limit set for intravenous recombinant tissue plasminogen activator. In this paper, the authors report their experience with various endovascular therapies in acute ischemic stroke. Methods The authors conducted a retrospective review of their clinical database for acute ischemic stroke in large-vessel cerebral territories that underwent endovascular treatment between May 2005 and February 2009. Endovascular treatment was defined as pharmacological and/or mechanical intervention, angioplasty, stenting, or a combination of these methods. Admission National Institutes of Health Stroke Scale and the modified Rankin Scale scores were recorded. Thrombolysis in Myocardial Infarction (TIMI) scores of 0, 1, 2A, 2B, and 3 were used to define recanalization. Results Forty procedures were performed in 39 patients, with 1 patient having sequential bilateral strokes. Nine patients were lost to follow-up after discharge. Strokes in the carotid artery circulation occurred in 82.5% of cases, and those in the vertebral-basilar territory occurred in 17.5%. The Merci device was used in 22 (55%) of 40 procedures, and the Penumbra device in 9 (22.5%) of 40. Angioplasty was performed in 15 (37.5%) of 40 procedures, and intraarterial recombinant tissue plasminogen activator was administered in 23 (57.5%) of 40 procedures. In 23 (57.5%) of 40 cases, multiple recanalization methods were used. The recanalization rate for all methods was 60%. The recanalization rate from TIMI Score 0/1 occlusions was 71.4% (20 of 28). An estimated modified Rankin Scale score of ≤ 2 was obtained in 11 (36.7%) of 30 cases. The overall mortality rate was 26.7% (8 of 30). Intracerebral hemorrhage at 24 hours postprocedure was noted in 17 (42.5%) of 40 cases, 3 (7.5%) of which were symptomatic. Conclusions The authors' institution performs endovascular stroke treatment with a safety and efficacy profile comparable to those of other major endovascular stroke therapy studies. Recanalization was associated with an improved clinical outcome. Protocols to maximize efficient triage of patients and better documentation of stroke treatments can assist in further studies.

Background: As compared with systemic i.v. thrombolytic therapy, primary endovascular treatment results in a higher rate of patency of the ischemic stroke-related cerebral artery. However, the comparative clinical efficacy of the two approaches has not been carefully studied. Methods: We randomly assigned a total of 362 patients with acute ischemic stroke seen within 4.5 h from symptoms onset to endovascular treatment (i.e., intra-arterial thrombolysis with recombinant tissue plasminogen activator - t-PA - if necessary, associated to or substituted by mechanical clot disruption and/or retrieval) or i.v. t-PA administered according to EU labeling. The purpose of the study was to determine the proportion of independent survivors at three months. Safety endpoints included symptomatic intracranial hemorrhage, death and other serious adverse events. Results: A total of 181 patients were assigned to undergo endovascular treatment, and 181 to receive i.v. t-PA. Median time from stroke onset to start to treatment was 3 h 45 min for endovascular treatment (range: 1 h 30 min to 5 h 55 min) and 2 h 45 min (range: 55 min to 4 h 30 min) for i.v. t-PA (p=0.002). All the randomized patients were assessed at 3 months and analyzed. We will present analyses comparing the effect of endovascular treatment with i.v. t-PA on a) the primary outcome (proportion of patients alive and independent at 3 months as assessed by the modified Rankin scale) adjusted for key covariates, b) death from any cause within 3 months, c) events within 7 days: fatal and non fatal symptomatic intracranial hemorrhages, fatal and non fatal neurological deterioration attributed to brain swelling from the initial ischemic stroke, fatal and non fatal neurological deterioration not attributed to swelling or intracranial hemorrhage, fatal and non fatal recurrent ischemic stroke, death from any cause. Conclusions: Data from the trial will provide new evidence on the balance of risk and benefit of endovascular treatment, as compared to systemic thrombolysis, among patients with acute ischemic stroke.

Background and purpose To examine sex differences in disease profiles and short-term outcomes after acute ischemic stroke treated with recombinant tissue plasminogen activator. Methods Eight national and regional stroke registries contributed individual participant data from mainland China, Japan, Philippines, Singapore, South Korea and Taiwan in 2005–2018. The primary outcome was ordinal-modified Rankin scale at 90 days. Key safety outcome was symptomatic intracerebral hemorrhage (sICH). Results Of 4453 patients included in the analyses, 1692 (36.3%) were women who were older, more likely to have a more severe neurological deficit, history of hypertension and atrial fibrillation, and a cardioembolic stroke compared to men. Women were more likely than men to have unfavorable shift of modified Rankin scale (fully adjusted odds ratio) (women vs. men) 1.14, 95% confidence interval 1.02–1.28). There was no significant sex difference for death 1.05 (0.84–1.31) or sICH (1.17, 0.89–1.54). Women were more likely to have unfavorable functional outcome with increasing age (P = 0.022 for interaction). In the age groups 70–80 and ≥80 years, women had a worse functional outcome compared to men (1.22, 1.02–1.47 and 1.43, and 1.06–1.92, respectively). Conclusion In this pooled data from Asian acute stroke registries, women had poorer prognosis than men after receiving recombinant tissue plasminogen activator for acute ischemic stroke, which worsened with age. Women older than 70 appear to have a worse outcome than men which could be explained by greater stroke severity, more AF, and cardioembolic stroke.

Objective:: Increased leukocyte count are positively associated with poor outcomes and all-cause mortality in coronary heart disease, cancer, and ischemic stroke. The role of leukocyte count in acute ischemic stroke (AIS) remains important. We aimed to investigate the association between admission leukocyte count before thrombolysis with recombinant tissue plasminogen activator (rt-PA) and 3-month outcomes in AIS patients. Methods:: This retrospective study included consecutive AIS patients who received intravenous (IV) rt-PA within 4.5 h of symptom onset between January 2016 and December 2018. We assessed outcomes including short-term hemorrhagic transformation (HT), 3-month mortality, and functional independence (modified Rankin Scale [mRS] score of 0–2 or 0–1). Results:: Among 579 patients who received IV rt-PA, 77 (13.3%) exhibited HT at 24 h, 43 (7.4%) died within 3 months, and 211 (36.4%) exhibited functional independence (mRS score: 0–2). Multivariable logistic regression revealed admission leukocyte count as an independent predictor of good and excellent outcomes at 3 months. Each 1-point increase in admission leukocyte count increased the odds of poor outcomes at 3 months by 7.6% (mRS score: 3–6, odds ratio (OR): 1.076, 95% confidence interval (CI): 1.003–1.154, p=0.041) and 7.8% (mRS score: 2–6, OR: 1.078, 95% CI: 1.006–1.154, p=0.033). Multivariable regression analysis revealed no association between HT and 3-month mortality. Admission neutrophil and lymphocyte count were not associated with 3-month functional outcomes or 3-month mortality. Conclusion:: Lower admission leukocyte count independently predicts good and excellent outcomes at 3 months in AIS patients undergoing rt-PA treatment.

Introduction: Intravenous recombinant tissue plasminogen activator (IV rtPA) is recommended treatment for acute ischemic stroke patients, but the cost-effectiveness of IV rtPA within different time windows after the onset of acute ischemic stroke is not well reviewed. Objectives: We conducted a literature review of the cost-effectiveness studies about IV rtPA. Methods: A literature search was conducted using PubMed, MEDLINE, and EconLit, with the key words stroke, cost, economic benefit, saving, cost-effectiveness, tissue plasminogen activator, and rtPA. The review is limited to original research articles published during 1995–2014 in English-language peer-reviewed journals. Results: We found 15 studies meeting our criteria for this review. Nine of them were cost-effectiveness studies of IV rtPA treatment within 0-3 hours after stroke onset, 2 studies within 3-4.5 hours, 3 studies within 0-4.5 hours, and 1 study within 0-6 hours. IV rtPA is a cost-saving or a cost-effectiveness strategy from most of the study results. Only one study showed incremental cost-effectiveness ratio of IV rtPA within one year was marginally above $50,000 per QALY threshold. IV rtPA within 0-3 hours after stroke led to cost savings for lifetime or 30 years, and IV rtPA within 3-4.5 hours after stroke increased costs but still was cost-effective. Conclusions: The literature generally showed that intravenous IV rtPA was a dominant or a cost-effective strategy compared to traditional treatment for acute ischemic stroke patients without IV rtPA. The findings from the literature lacked generalizability because of limited data and various assumptions.
