Background: The effectiveness of comprehensive stroke center (CSC) capabilities on outcome of carotid endarterectomy (CEA) and carotid artery stenting (CAS) remains uncertain. We performed a nationwide study to examine whether CSC capabilities influenced in-hospital outcome of CEA and CAS. Methods: We analyzed 12,943 carotid artery stenosis patients treated with CEA or CAS in 350 certified training hospitals in Japan. Data between April 1, 2013 and May 31, 2015 was obtained from Japanese Diagnosis Procedure Combination Database. Among the institutions that responded, outcome was assessed by in-hospital mortality, ischemic stroke and myocardial infarction. CSC capabilities were evaluated from the 749 certified training institutions in Japan, which responded to a questionnaire survey regarding CSC capabilities that queried the availability of personnel, diagnostic techniques, specific expertise, infrastructure, and educational components recommended for CSCs. Total CSC scores of the participating hospitals were classified into quartiles (Q1: 0-15, Q2: 16-17, Q3: 18-19, Q4: 20-24). Results: The proportion of CEA and CAS were 5068 and 7875 (2013: 1685 and 2590, 2014: 1668 and 2564, 2015: 1715 and 2721). Between CEA and CAS, mortality rates were 0.24% and 0.75%, ischemic stroke were 8.41% and 7.56% and myocardial infarction were 0.76% and 0.17%. These outcomes had no differences among the years. There was tendency that mortality rates were lower with high total CSC scores in patients with CEA (Q1: 0.42%, Q2: 0.26%, Q3: 0.12%, Q4: 0%, P=0.16), but there were no differences with CAS (Q1: 1.0%, Q2: 0.74%, Q3: 0.63%, Q4: 0.83%, P=0.73). Ischemic stroke were significantly lower with high CSC scores in CEA (Q1: 9.76%, Q2: 10.77%, Q3: 9.14%, Q4: 6.59%, P<0.05) and CAS (Q1: 9.86%, Q2: 8.76%, Q3: 7.14%, Q4: 6.98%, P<0.05). Myocardial infarction had no correlation with CSC scores in CEA (Q1: 0.21%, Q2: 0.35%, Q3: 0%, Q4: 0.36%, P=0.37) and CAS (Q1: 0.3%, Q2: 0%, Q3: 0.31%, Q4: 0.16%, P=0.19). Conclusion: It is reported using the data of Nationwide Inpatient Sample that operator volume was an important predictor of postprocedural outcomes in CAS. We demonstrated that CSC capabilities were associated with reduced in-hospital ischemic stroke in patients with CEA and CAS.

Background: The effectiveness of comprehensive stroke center (CSC) capacities on stroke mortality remains uncertain. We examined whether specific CSC capacities influenced in-hospital mortality of patients with ischemic and hemorrhagic stroke in a nationwide study. Methods and Results: Of 749 certified training institutions in Japan responded to a questionnaire survey regarding CSC capacities, specifically regarding the availability of personnel, diagnostic techniques, specific expertise, infrastructure, and educational components recommended for CSCs, 265 institutions agreed to participate in this study. Data on patients hospitalized for stroke between April 1, 2010 and March 31, 2011 were obtained from the Japanese Diagnosis Procedure Combination database. In-hospital mortality was analyzed using hierarchical logistic regression analysis adjusted for age, sex, level of consciousness on admission, and 25 fulfilled CSC items in each component. Data from 265 institutions and 53,170 emergency-hospitalized patients were analyzed. Mortality rates were 7.8% for patients with ischemic stroke, 16.8% for patients with intracerebral hemorrhage (ICH), and 28.1% for patients with subarachnoid hemorrhage (SAH). Mortality adjusted for age, sex, and level of consciousness was significantly correlated with different items in the five components recommended for CSC depending on stroke types (Table 1 and 2). Conclusions: CSC capacities were associated with reduced in-hospital mortality rates, and relevant aspects of care were found to be dependent on the type of stroke.

Background:A meta-analysis of randomized controlled trials (RCTs) was conducted to update the available evidence on the safety and efficacy of carotid endarterectomy (CEA) versus carotid artery stenting (CAS) in the treatment of carotid artery stenosis.Methods:A comprehensive search was performed of MEDLINE, EMBASE, CENTRAL, bibliographies of included articles and past systematic reviews, and abstract lists of recent scientific conferences. For each reported outcome, a Mantel-Haenszel random-effects model was used to calculate odds ratios (ORs) and 95% confidence intervals (CI). The I2 statistic was used as a measure of heterogeneity.Results:Twelve RCTs enrolling 6,973 patients were included in the meta-analysis. Carotid artery stenting was associated with a significantly greater odds of periprocedural stroke (OR 1.72, 95% CI 1.20 to 2.47) and a significantly lower odds of periprocedural myocardial infarction (OR 0.47, 95% CI 0.29 to 0.78) and cranial neuropathy (OR 0.08, 95% CI, 0.04 to 0.16). The odds of periprocedural death (OR 1.11, 95% CI 0.56 to 2.18), target vessel restenosis (OR 1.95, 95% CI 0.63 to 6.06), and access-related hematoma were similar following either intervention (OR 0.60, 95% CI 0.30 to 1.21).Conclusions:In comparison with CEA, CAS is associated with a greater odds of stroke and a lower odds of myocardial infarction. While the results our meta-analysis support the continued use of CEA as the standard of care in the treatment of carotid artery stenosis, CAS is a viable alternative in patients at elevated risk of cardiac complications.

Background: Traditionally, patients undergoing acute ischemic strokes were candidates for mechanical thrombectomy if they were within the 6-h window from onset of symptoms. This timeframe would exclude many patient populations, such as wake-up strokes. However, the most recent clinical trials, DAWN and DEFUSE3, have expanded the window of endovascular treatment for acute ischemic stroke patients to within 24 h from symptom onset. This expanded window increases the number of potential candidates for endovascular intervention for emergent large vessel occlusions and raises the question of how to efficiently screen and triage this increase of patients. Summary: Abbreviated pre-hospital stroke scales can be used to guide EMS personnel in quickly deciding if a patient is undergoing a stroke. Telestroke networks connect remote hospitals to stroke specialists to improve the transportation time of the patient to a comprehensive stroke center for the appropriate level of care. Mobile stroke units, mobile interventional units, and helistroke reverse the traditional hub-and-spoke model by bringing imaging, tPA, and expertise to the patient. Smartphone applications and social media aid in educating patients and the public regarding acute and long-term stroke care. Key Messages: The DAWN and DEFUSE3 trials have expanded the treatment window for certain acute ischemic stroke patients with mechanical thrombectomy and subsequently have increased the number of potential candidates for endovascular intervention. This expansion brings patient screening and triaging to greater importance, as reducing the time from symptom onset to decision-to-treat and groin puncture can better stroke patient outcomes. Several strategies have been employed to address this issue by reducing the time of symptom onset to decision-to-treat time.

Objectives The purpose of this study was to conduct a meta-analysis to systematically compare the safety and efficacy of carotid endarterectomy and carotid artery stenting in contralateral carotid occlusion patients who needed reperfusion. Methods This study retrieved potential academic articles comparing results between carotid endarterectomy and carotid artery stenting for patients with contralateral carotid occlusion from the MEDLINE database, the PubMed database the EMBASE database, and the Cochrane Library from January 1990 to May 2018. The reference articles for the identified studies were carefully reviewed to ensure that all available documents were represented in the study. Results Four retrospective cohort study involving 6252 patients with contralateral carotid occlusion were included in our meta-analysis. During 30-day follow-up, there is significant difference in post-procedure mortality (odds ratio (OR) = 0.476, 95% confidence interval (CI) (0.306–0.740), P = 0.001); no significant differences are not found in post-procedure stroke (risk difference (RD) = 0.002, 95%CI (–0.007 to 0.011); P = 0.631), myocardial infarction (RD = 0.003, 95%CI (–0.002 to 0.008); P = 0.301), and transient cerebral ischemia (RD = 1.059, 95%CI (–0.188 to 5.964); P = 0.948). Conclusions Carotid endarterectomy was associated with a lower incidence of mortality compared to carotid artery stenting for patients with contralateral carotid occlusion. Regarding stroke, myocardial infarction, and transient ischemic attack, there was no significant difference between the two groups. More randomized controlled trials and prospective cohorts are necessary to help further clarify the ideal approach for these patients.

<strong>Background:</strong> Treatment method in patients with coronary artery disease undergoing coronary bypass surgery with accompanying carotid artery disease is still a hot topic among clinicians. This study is designed to investigate if there is an effect on myocardial infarction, cerebrovascular events and mortality during postoperative period of simultaneous carotid endarterectomy with coronary bypass surgery compared to staged carotid artery stenting before coronary bypass surgery.<br /><strong>Methods:</strong> 102 patients (79 male, 23 female) who underwent simultaneous carotid endarterectomy with coronary bypass surgery or staged carotid artery stenting with coronary bypass surgery in the same center with the same surgical team were divided into 2 groups and retrospectively reviewed. Group 1 (n = 71) had coronary artery bypass surgery under general anesthesia with carotid endarterectomy followed by cardiopulmonary bypass with heart team decision. Again with heart team decision, Group 2 (n=31), patients at high-risk for carotid endarterectomy (serious cardiac disease, severe chronic obstructive pulmonary disease, superiorly located lesions), received carotid artery stents in the interventional radiology department and a month later, coronary bypass surgery was performed with cardiopulmonary bypass under elective conditions.<br /><strong>Results:</strong> Median of patient age was 67.5 (45-83) years. Twenty-two patients (31%) in Group 1 and 19 patients (56.3%) in Group 2 had neurological symptoms, which was statistically significant (P = .004). During the early postoperative term, three patients (4.2%) in Group 1 and two patients (6.5%) in Group 2 died (P = .64). Five patients (7.0%) in Group 1 and two patients (6.5%) in Group 2 developed neurological symptoms during the early postoperative term <br />(P &gt; .05). Likewise, two patients (2.8%) in Group 1 and five patients (16.1%) in Group 2 developed myocardial infarction following carotid intervention (P = .03).<br /><strong>Conclusions:</strong> In patients with significant carotid artery stenosis undergoing coronary bypass surgery with cardiopulmonary bypass, in comparison to simultaneous carotid endarterectomy with coronary bypass technique and carotid artery stenting followed with coronary bypass technique showed no difference in combined endpoint (postoperative myocardial infarction, neurological events, and mortality). With proper tools and according to the decisions made by heart teams, both management strategies can be safely performed.<br /><br />

Measurement of quality of stroke care has become increasingly important, but data come mostly from programs in hospitals that choose to participate in certification programs, which may not be representative of the care provided in nonparticipating hospitals. The authors sought to determine differences in quality of care metric concordance for acute ischemic stroke among hospitals designated as a primary stroke center, comprehensive stroke center, and non-stroke center in a population-based epidemiologic study. Significant differences were found in both patient demographics and in concordance with guideline-based quality metrics. These differences may help inform quality improvement efforts across hospitals involved in certification as well as those that are not.

Background Carotid artery stenting requires antiplatelet therapy for prevention of in-stent thrombosis. Patients suffering from acute ischemic stroke undergoing intravenous thrombolysis and emergent carotid artery stenting (eCAS) are at high risk for intracranial bleeding. We assessed efficacy and safety of acute administration of intravenous tirofiban versus aspirin in these patients. Methods A retrospective, single center, cohort study was carried out of 32 patients who underwent eCAS (18 received tirofiban, 14 received aspirin) at our comprehensive stroke center (2008–2016). Results Of our 32 consecutive eCAS patients, favorable clinical outcomes (modified Rankin scale ≤ 2) were achieved in eight (47%) tirofiban patients and six (46%) aspirin patients ( p = 0.96). Overall rates were similar for symptomatic intracranial bleeding (tirofiban 22%, aspirin 29%, p = 0.68) and mortality (tirofiban 18%, aspirin 23%, p = 0.71). Conclusions Tirofiban and aspirin demonstrated similar efficacy and safety in thrombolyzed stroke patients who underwent eCAS in our cohort. Intravenous tirofiban with its short half-life might represent an alternative to aspirin in select patients.

Background: Carotid Endarterectomy (CEA) and Carotid Artery Stenting (CAS) are both viable treatment options for carotid artery stenosis. Factors including surgical risk, age, and symptomatic status are often used to help guide management decisions. Methods: We conducted a retrospective observational study using the National Surgical Quality Improvement Program (NSQIP) database to compare 30-day post-procedure outcomes including mortality, stroke, and myocardial infarction in patient with carotid stenosis undergoing CEA (n=54,640) versus CAS (n=488) from 2005 to 2012. Procedure type was identified by CPT codes. Findings: Patients undergoing CEA were more likely to be older and have symptomatic stenosis, and less likely to be white, have CHF, and have COPD. There was no significant difference between CEA and CAS in 30-day mortality (0.9% vs. 1.2%, p=0.33), stroke (1.6% vs. 1.6% p=0.93), myocardial infarction (0.9% vs. 1.6%, p=0.08), or combined outcome (3.0% vs. 4.9%, p=0.09). The interaction between symptomatic status and procedure type was not significant (p=0.29), indicating the association of symptomatic status with 30-day mortality was similar in cases receiving CEA and CAS. Conclusion: Early outcomes after CEA and CAS for carotid artery stenosis appear to be similar in a ‘real-world’ sample and comparable to clinical trials. Patients undergoing CAS were more likely to be younger and surgically higher risk based on baseline characteristics likely reflecting clinical practice case selection.
