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 Functional outcome post-stroke depends on time to recanalization. Effect of in-hospital delay may differ in patients directly admitted to a comprehensive stroke center and patients transferred via a primary stroke center. We analyzed the current door-to-groin time in Germany and explored its effect on functional outcome in a real-world setting. Methods Data were collected in 25 stroke centers in the German Stroke Registry-Endovascular Treatment a prospective, multicenter, observational registry study including stroke patients with large vessel occlusion. Functional outcome was assessed at three months by modified Rankin Scale. Association of door-to-groin time with outcome was calculated using binary logistic regression models. Results Out of 4340 patients, 56% were treated primarily in a comprehensive stroke center and 44% in a primary stroke center and then transferred to a comprehensive stroke center (“drip-and-ship” concept). Median onset-to-arrival at comprehensive stroke center time and door-to-groin time were 103 and 79 min in comprehensive stroke center patients and 225 and 44 min in primary stroke center patients. The odds ratio for poor functional outcome per hour of onset-to-arrival-at comprehensive stroke center time was 1.03 (95%CI 1.01–1.05) in comprehensive stroke center patients and 1.06 (95%CI 1.03–1.09) in primary stroke center patients. The odds ratio for poor functional outcome per hour of door-to-groin time was 1.30 (95%CI 1.16–1.46) in comprehensive stroke center patients and 1.04 (95%CI 0.89–1.21) in primary stroke center patients. Longer door-to-groin time in comprehensive stroke center patients was associated with admission on weekends (odds ratio 1.61; 95%CI 1.37–1.97) and during night time (odds ratio 1.52; 95%CI 1.27–1.82) and use of intravenous thrombolysis (odds ratio 1.28; 95%CI 1.08–1.50). Conclusion Door-to-groin time was especially relevant for outcome of comprehensive stroke center patients, whereas door-to-groin time was much shorter in primary stroke center patients.

Background: It has been established that safety and outcomes of intravenous thrombolysis (IVT) to stroke patients via telestroke (TS) is similar to those presenting to stroke centers. Little is known on the accuracy of TS diagnosis among those receiving IVT. We sought to compare the rate of stroke mimic (SM) patients receiving IVT in our TS network to those who present to our comprehensive stroke center (CSC). Methods: Consecutive patients receiving IVT between August 2014 and June 2015 were identified at our CSC and TS network. The rates of SM patients in each cohort were calculated. Outcomes measured included rates of symptomatic intracerebral hemorrhage (sICH), in-hospital mortality, and discharge to home or an acute rehabilitation unit (ARU). Results: During the study period, 132 patients (mean age 71±15 years, 49% women) receiving IVT were included in the analysis (75 CSC, 57 TS). Rates of SM patients receiving IVT were similar (CSC 12% vs TS 7%, p=0.39). One stroke patient developed sICH, and three other stroke patients experienced in-hospital mortality; neither outcome was found in the SM cohort. Discharge to home or ARU was similar between stroke (76.5%) and SM (76.9%) patients (p=1). Patients with SMs had significantly higher diagnoses of migraine (p=0.045) and psychiatric disorders (p=0.0002) compared to stroke patients. Conclusion: The rate of IVT among SM patients via TS is low and similar to those who present directly to a stroke center. Continued efforts should be made to further minimize IVT in SM patients despite the low rate of complications.

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: Improved clinical outcomes after intravenous tissue plasminogen activator (IV tPA) are time dependent. Participation in a telestroke program allows the spoke hospitals 24/7 access to a vascular fellowship trained neurologist for a telestroke consult, as well as educational partnership with the hub site, shared protocols, and access to quality improvement feedback. We sought to assess the effects of continued participation in a telestroke program on times to administration of IV tPA. Methods: Our institutional telestroke program began in March 2011 and consists of an academic hub (comprehensive stroke center) that serves 8 community spoke hospitals. We retrospectively reviewed acute ischemic stroke patients treated with IV tPA via the telestroke program. We compared 2 cohorts of patients: Period 1 (July 2011 to June 2013) and Period 2 (July 2013 to July 2014). We collected data on demographics, National Institutes of Health Stroke Scale (NIHSS), and times from initiation of telestroke consult to IV tPA administration. Results: Among 259 consecutive stroke patients (mean: 69.6 years, 56% female) treated with IV tPA via telestroke, the median NIHSS score was 11.8, and 41.7% of patients were transferred to the hub. The mean time from initiation of telestroke consult to IV tPA administration was 42.2 minutes. Period 1 included 129 patients and Period 2 included 130 patients, and the two groups did not differ by age (p=0.2), gender (p=0.3), or NIHSS score (p=0.3). Time from initiation of telestroke consult to IV tPA administration improved from Period 1 to Period 2 (35 vs. 49.9 minutes, p<0.0001). This improvement was due to faster mean time from initiation of telestroke consult to IV tPA advised (12.5 vs. 17.4 minutes, p<0.0001) and faster mean time from IV tPA advised to administration (22.5 vs. 33.1 minutes, p<0.0001). Conclusions: Maturation of a telestroke program is associated with improvement in the timeliness of IV tPA delivery, possibly due to a learning effect that continues the longer the sites participate in the program. This improvement is due to faster responses in both the hub site (recommending IV tPA earlier) and spoke site (administering IV tPA quicker). Further studies aimed at improving delivery of IV tPA in telestroke program are warranted.

Abstract Background Intravenous thrombolysis (IVT) with alteplase is the first-line therapy for acute ischemic anterior and posterior circulation strokes (ACS and PCS). Knowledge about safety and efficacy of IVT in posterior circulation stroke is deficient as most of the Egyptian studies either assessed IVT outcome in comparison to conservative therapy or its outcome in anterior circulation stroke only. Therefore, our aim was to compare the relative frequency and outcome after intravenous thrombolysis in anterior versus posterior circulation stroke patients presenting to stroke centers of Ain Shams University hospitals (ASUH). Results A total of 238 anterior circulation stroke and 61 posterior circulation strokes were enrolled, onset-to-door and door-to-needle time were statistically insignificant. NIHSS showed comparable difference at all time points despite higher scores along anterior circulation stroke; 90-day modified Rankin Scale (mRS) showed significant improvement in both groups from mRS >2 to ≤2 with a better percentage along posterior circulation stroke patients. There was insignificant difference for either incidence of death or intracranial hemorrhage (ICH) between the two groups. Conclusion IVT significantly reduced NIHSS for both anterior and posterior circulation stroke along different studied time points. Meanwhile, a higher percentage of patients with posterior circulation stroke had a better mRS outcome at 90 days.

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.

Introduction: Patient dissatisfaction and medication non-compliance correlate with patient misunderstanding of their medications and care plan. We aimed to assess the degree of these gaps and their associations in hospitalized stroke patients. Methods: A 5-question survey was administered to patients hospitalized on the neuroscience ward of a comprehensive stroke center. Patient understanding of their condition leading to admission, care plan, medications, primary attending physician, and follow-up plan was assessed. If the patient was unable to communicate, then their health care representative was interviewed. Results: A total of 146 patients (55 stroke and 91 general neurology and neurosurgery (non-stroke) patients) or their representatives were interviewed. Stroke patients were less likely to properly identify their primary attending physician (33/55 (60.0%) stroke patients versus 35/91 (38.5%) non-stroke patients; p=0.011). Inability to identify the attending physician was associated with lack of medication and care plan knowledge and was more common in stroke patients, (23/33 (69.7%) stroke patients versus 14/35 (40.0%) non-stroke patients; p=0.014). Conclusion: Despite sharing a common pool of providers, the inability to identify the primary attending physician was significantly more common in stroke patients and was associated with patient knowledge deficits regarding their medication regimen and care plan. This correlation was significantly higher in stroke patients and suggests that stroke patients may require different, extra or more robust communication and education than the general neurology and neurosurgery population. Additionally, emphasis on attending physician identification may improve patient satisfaction and medication compliance.

Background: “Drip-and-ship” denotes patients in whom intravenous (IV) recombinant tissue plasminogen activator (rt-PA) is initiated at the emergency department (ED) of a community hospital, followed by transfer within 24 hours to a comprehensive stroke center. Although drip-and-ship paradigm has the potential to increase the number of patients who receive IV rt-PA, comparative outcomes have not been assessed at a population based level. Methods: State-wide estimates of thrombolysis, associated in-hospital outcomes and mortality were obtained from 2008-2009 Minnesota Hospital Association (MHA) data. Patient numbers and frequency distributions were calculated for state-wide sample of patients hospitalized with a primary diagnosis of ischemic stroke. Patients outcomes were analyzed after stratification into patients treated with IV rt-PA through primary ED arrival or drip-and-ship paradigm. Results: Of the 21,024 admissions, 602 (2.86%) received IV rt-PA either through primary ED arrival (n=473) or drip-and-ship paradigm (n=129). The rates of secondary intracerebral or subarachnoid hemorrhage were higher in patients treated with IV rt-PA through primary ED arrival compared with those treated with drip-and-ship paradigm (8.5% versus 3.1, p=0.038). The in-hospital mortality rate was similar among ischemic stroke patients receiving IV rt-PA through primary ED arrival or drip-and-ship paradigm (5.9% versus 7.0%). The mean hospital charges were $65,669 for primary ED arrival and $47,850 for drip-and-ship treated patients (p<0.001). Conclusions: The results of drip-and-ship paradigm compare favorably with IV rt-PA treatment through primary ED arrival in this state-wide study.

Background: An echocardiogram or transcranial Doppler (TCD) bubble study to test for a right-to-left shunt (RLS) is a standard component of an ischemic stroke workup. Because the pathway for an intracradiac RLS, such as a patent foramen ovale (PFO), is more direct, it has been proposed that the late appearance of a RLS suggests an extracardiac pathway. We sought to characterize a cohort of ischemic stroke patients with late RLS (LRLS) on TCD. Methods: We searched the medical record of a Comprehensive Stroke Center for patients with ischemic stroke who had a TCD and echocardiogram bubble study during 2011-2013. LRLS was defined as TCD bubbles appearing more than 18 cardiac cycles after contrast injection. TOAST stroke etiology classification was performed by a vascular neurologist blinded to TCD results. Results: 124 patients met inclusion criteria, of which 67/124 (54%) had RLS on TCD; and 32/67 (48%) had LRLS. In the 35/67 patients with normal RLS on TCD, 23% did not have RLS on echocardiography, consistent with prior reports of TCD’s superiority for detecting RLS. In the 32/67 patients with LRLS on TCD, 56% were negative for RLS by echocardiography. In the cohort of 124 patients, the percentage of TOAST classification 4 (stroke of other determined cause) was 26%, while in the 32 patients with LRLS the percentage of TOAST 4 was significantly higher at 52%(p=0.005) (Table 1). The increase in TOAST 4 in LRLS patients was created by an even distribution of decreases in the other TOAST categories. The most common TOAST 4 stroke etiology in LRLS patients was PFO with concurrent deep venous thrombosis. Conclusion: This preliminary data supports prior studies that have shown superiority of TCD over echocardiography for detection of RLS, and challenge the prevailing notion that extracardiac shunt, such as pulmonary AVM, is the most common cause of LRLS in ischemic stroke patients. This subgroup of patients warrants further research to clarify mechanisms of ischemic stroke in patients with RLS.
