Background: The aim of the study was to assess the relevance of chronic rhinosinusitis (CRS) CT features to the efficacy of mechanical thrombectomy (MT) in patients with acute ischemic stroke. Methods: This study included 311 patients qualified for MT in whom the CRS features were assessed based on a CT scan, according to the Lund-Mackay (L-M) score. Clinical, inflammatory parameters, patients neurological (NIHSS) and functional status (mRS), and recanalisation efficacy (TICI) were compared between patients with mild lesions (L-M score 0–3 points)-group 1, and patients with more severe lesions (L–M score 4–24)-group 2. Results: There was a significant difference in the NIHSS on day seven after stroke onset-10 points in group 1 and 14 points in group 2, p = 0.02. NIHSS ≤ 6 points on day seven was found in 41.9% of patients in group 1, and in 27.5% in group 2, p = 0.042. There were no significant differences in mRS score and in the TICI score. L-M score, lipid abnormalities and CRP were factors associated with NIHSS ≥ 7 points on day 7. Conclusions: The CT features of CRS may be used as a prognostic tool for early prognosis assessment in stroke patients.

Introduction: Readmission after acute ischemic stroke is common and costly, with an average rate of 14.8% within 30 days of discharge1. In 2010, as part of a hospital performance improvement strategy, ischemic stroke patients who were discharged to home had an urgent (within 7 days) appointment with Primary Care Physician (PCP) scheduled. We compared 30-day readmission rates for those who kept and did not keep their appointment. Methods: Data from an electronic medical record system was retrospectively evaluated. The cohort included all patients with hospital admission for ICD 9 diagnosis of ischemic stroke (433, 434, 435) during the years 2010 - 2013. Only those with a discharge disposition of home were included. Group 1 included patients discharged to home who kept follow up appointment. Group 2 included those who did not keep their scheduled appointment. Significant predictors of readmission such as age, heart failure, diabetes, LACE score were compared. Fisher’s Exact test was used for categorical variables. Results: A total of 349 ischemic stroke patients were discharged to home during the study period. Of these, 250 had appointments scheduled, and 167 (66.8%) kept these appointments (Group 1). The average age was 69.2 and 68.3 with average LACE of 9.7 and 9.5 for groups 1 and 2 respectively. There was no significant difference in rates of diabetes or heart failure between groups. There were 7 (3.6%) readmissions in group 1 and 19 of 83 (22.9%) in group 2. Five patients were readmitted prior to appointment time in group 2, so were not entered into final calculation; this left readmission rate of 14/83 (16%); p =0.004. Conclusion: Urgent follow up with PCP may prevent hospital readmission in those with mild strokes. Reverse causation, from missing appointment due to hospital readmission did not account for these results. Although NIHSS was not compared, our cohort consisted of those with mild symptoms, given home disposition. Further study is needed to determine which elements of the PCP follow up visit are most effective in reducing hospital readmission. Reference: 1. Lichtman, JH. Leifheit-Limson, EC.

Stent Retrievers

Background: There is controversy regarding the optimal size of stent retriever for achieving timely recanalization in acute ischemic stroke patients. Objective: To determine the relationship between stent retriever diameter and procedure time, and rates of recanalization, and functional independence among acute ischemic stroke patients undergoing mechanical thrombectomy. Methods: We analyzed data from consecutive acute ischemic stroke patients treated with mechanical thrombectomy derived from a prospective database. Baseline demographic and clinical characteristics, NIHSS score on admission and discharge, intracranial hemorrhage occurrence, and mRS at discharge were analyzed. Thrombolysis In Cerebral Infarction (TICI) scale was used to grade pre and post procedure angiographic recanalization. Procedural time was defined by the time interval between microcatheter placement and recanalization. We compared the rates of thrombectomy attempts, complete recanalization (TICI grade of 3), and functional independence (defined by mRS 0-2) between patients treated with 6 mm and 3-4 mm diameter stent retrievers. Results: A total of 230 acute ischemic stroke patients (mean age 71.8 ±12.5; 46.6% women) were treated with stent retrievers. Thrombectomy was performed with a 6mm diameter stent retriever in 107 patients and 3 or 4 mm diameter stent retriever in 123 patients. There were no statistically significant differences in demographics or baseline characteristics, or admission NIHSS score between the two groups. There was a trend towards a fewer number of thrombectomy attempts required with a 6mm diameter stent retriever (p=0.06). There was a higher rate of complete recanalization in patients treated with 6mm diameter stent retriever compared with 3 or 4 mm diameter stent retriever (72% vs 57.7% p=0.02). There was no statistically significant difference in rates of functional independence between the two groups (24.3% vs 25.2% p=0.84) at discharge. Conclusion: Among acute ischemic stroke patients undergoing mechanical thrombectomy, use of a 6 mm diameter stent retriever was associated with a higher rate of complete recanalization and a lower number of thrombectomy attempts compared with 3-4 mm diameter stent retrievers.

Background and purposeThe use of CT perfusion (CTP) imaging at a referring hospital is feasible and may shorten the door to puncture time for patients with acute ischemic stroke.MethodsWe conducted a single center retrospective review of a prospectively maintained database of consecutive ischemic stroke patients transferred to our center for consideration of endovascular therapy. Patients were divided into two groups. Group 1 consisted of patients transferred from facilities where CTP (using automated RAPID software) was routinely performed and group 2 consisted of patients transferred from facilities that did not perform perfusion imaging.ResultsWe identified a total of 132 patients, all of whom were transferred to our center, from April 2014 to April 2017. There were no differences in baseline characteristics between the two groups. A total of 34 patients were transferred from a facility after CTP (group 1) and 98 were transferred from a facility with no CTP (group 2). Door to puncture time was significantly shorter for patients in group 1 compared with those in group 2 (median 12 (IQR 8–16) min and 48.5 (32.8–71.8) min, respectively; P<0.001). Despite obtaining additional pre-transfer imaging in group 1, there was no difference in door in and door out times at the referring facilities compared with group 2.ConclusionsWe found that triaging from a primary stroke center after CTP RAPID was feasible and significantly reduced the door to puncture time without any significant delay in the transfer process.

Aspiration Technique

Background: Mechanical thrombectomy is the standard therapy in patients with acute ischemic stroke (AIS). The primary aim of our study was to compare the procedural efficacy of the direct aspiration technique, using Penumbra ACETM aspiration catheter, and the stent retriever technique, with a SolitaireTM FR stent. Secondarily, we investigated treatment-dependent and treatment-independent factors that predict a good clinical outcome. Methods: We analyzed our series of mechanical thrombectomies using a SolitaireTM FR stent and a Penumbra ACETM catheter. The clinical and radiographic data of 76 patients were retrospectively reviewed. Using binary logistic regression, we looked for the predictors of a good clinical outcome. Results: In the Penumbra ACETM group we achieved significantly higher rates of complete vessel recanalization with lower device passage counts, shorter recanalization times, shorter procedure times and shorter fluoroscopy times (p < 0.001) compared to the SolitaireTM FR group. We observed no significant difference in good clinical outcomes (52.4% vs. 56.4%, p = 0.756). Predictors of a good clinical outcome were lower initial NIHSS scores, pial arterial collateralization on admission head CT angiography scan, shorter recanalization times and device passage counts. Conclusions: The aspiration technique using Penumbra ACETM catheter is comparable to the stent retriever technique with SolitaireTM FR regarding clinical outcomes.

Background: It is reported that pre-stroke cognitive impairment is associated with poor functional outcome after stroke associated with small vessel disease. However, it is not clear that pre-stroke cognitive impairment is associated with poor outcome in patients treated with mechanical thrombectomy. Method: We enrolled 127 consecutive patients treated with mechanical thrombectomy for acute ischemic stroke from December 2016 to November 2018. Pre-stroke cognitive function was evaluated using the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). We retrospectively compared poor outcome (a score of 3 to 6 on the modified Rankin Scale at 90 days) group (n=75) with good outcome (a score of 0, 1, or 2 on the modified Rankin Scale at 90 days) group (n=52) and examined that IQCODE could be the predictor of PO. Result: IQCODE was significantly higher in poor outcome group than in good outcome group (89 vs. 82, P=0.0012). Moreover, age (77.2 years old vs. 71.6 years old, P= 0.0009), the percentage of female (42.7% vs. 17.3%, P= 0.0021), complication of hypertension (HT, 68.0% vs. 44.2%, P=0.0076), National Institutes of Health Stroke Scale (NIHSS) at admission (20 vs. 11, P<0.0001), the percentage of postoperative intracerebral hemorrhage (ICH, 33.3% vs. 15.4%, P=0.0233) were higher in poor outcome group than in good outcome group, too. However, there was no significant difference between poor outcome and good outcome groups in occlusion site (P= 0.1229), DWI-ASPECTS (P= 0.2839), the duration from onset to recanalization (P=0.4871) and other risk factors. Multivariable logistic regression analysis demonstrated that IQCODE, HT and NIHSS at admission were associated with poor outcome (P= 0.0128, P=0.0061 and P<0.0001, respectively). Conclusion: Cognitive impairment could be associated with poor outcome in patients treated with mechanical thrombectomy.

Objective To investigate whether significant differences exist in recanalization rates and primary outcomes between patients who undergo mechanical thrombectomy alone versus those who undergo mechanical thrombectomy with acute intracranial stenting. Methods Through the utilization of a prospectively collected endovascular database at a comprehensive stroke center between 2012 and 2020, variables such as demographics, co-morbid conditions, symptomatic intracerebral hemorrhage, mortality rate at discharge, and good/poor outcomes in regard to modified thrombolysis in cerebral infarction score and modified Rankin Scale were examined. The outcomes between patients receiving acute intracranial stenting + mechanical thrombectomy and patients that underwent mechanical thrombectomy alone were compared. Results There were a total of 420 acute ischemic stroke patients who met criteria for the study (average age 70.6 ± 13.01 years; 46.9% were women). Analysis of 46 patients from the acute stenting + mechanical thrombectomy group (average age 70.34 ± 13.75 years; 37.0% were women), and 374 patients from the mechanical thrombectomy alone group (average age 70.64 ± 12.92 years; 48.1% were women). Four patients (8.7%) in the acute stenting + mechanical thrombectomy group experienced intracerebral hemorrhage versus 45 patients (12.0%) in the mechanical thrombectomy alone group ( p = 0.506); no significant increases were noted in the median length of stay (7 vs 8 days; p = 0.208), rates of modified thrombolysis in cerebral infarction 2B-3 recanalization ( p = 0.758), or good modified Rankin Scale scores ( p = 0.806). Conclusion Acute intracranial stenting in addition to mechanical thrombectomy was not associated with an increase in overall length of stay, intracerebral hemorrhage rates, or any change in discharge modified Rankin Scale. Further research is required to determine whether mechanical thrombectomy and acute intracranial stenting in acute ischemic stroke patients is unsafe.

Aim: to study the stroke-associated pneumonia (SAP) effect on the outcome of ischemic stroke (IS) in the internal carotid artery system. Patients and Methods: 87 patients with IS underwent the follow-up study, of which 75 had no inflammatory bronchopulmonary complications (group 1), and 12 had pneumonia manifestation (group 2). The study was performed on days 1, 5, and 9 after IS, and 6 months and 12 months after discharge from the hospital. Neurological deficit severity (NIHSS, Barthel index) and inflammatory markers (peripheral blood leukocyte composition, C-reactive protein (CRP), ESR) were studied. Results: it was found that the presence of SAP was associated with increased mortality during the acute IS period (4 (33.1%) patients died in group 1 and 10 (13.3%) — in group 2, p<0.05), greater severity of neurological deficits (63.3±5.3 and 71.5±4.0 points on the NIHSS scale, respectively, p<0.05) and incapacitation (Barthel index — 63.3±5.3 and 71.5±4.0 points, respectively, p<0.05) at the end of the inpatient treatment period. In group 2, signs of an inflammatory response were detected on day 5, and the values of the white blood cell shift index, ESR and CRP significantly (p<0.05) differed from the initial values. During examination at 6 months and 12 months, there were no significant differences in these indicators between the groups. An association was established between the probability of SAP occurrence and the presence of swallowing disorders (r=0.672; p<0.05), the age of patients (r=0.572; p<0.05) and the presence of diabetes mellitus (r=0.522; p<0.05). The studied laboratory inflammatory markers allow us to timely assume the occurrence of pulmonary pathology. Conclusion: timely diagnosis and prevention of SAP can reduce the risk of fatal outcome, facilitate rehabilitation measures, and improve early IS outcomes.
