Background and purposeTo report clinical and procedural outcomes of acute ischemic stroke patients after endovascular treatment with the new thromboaspiration catheter AXS Catalyst 6.MethodsPatients with anterior and posterior circulation stroke were selected. Successful reperfusion defined as a Thrombolysis in Cerebral Infarction (TICI) score ≥2 b and 3-month functional independence defined as a modified Rankin Scale (mRS) ≤2 were the main efficacy outcomes. Symptomatic intracranial hemorrhage and mortality were the main safety outcomes.Results107 patients were suitable for analysis. Mean age was 73.18±12.62 year and median baseline NIHSS was 17 (range: 3–32). The most frequent site of occlusion was the middle cerebral artery (MCA) (60.7%). 76.6% of patients were treated with AXS Catalyst 6 alone without the need for rescue devices or thromboaspiration catheters. Successful reperfusion was achieved in 84.1%, functional independence in 47.6%, symptomatic intracranial hemorrhage occurred in 3.7%, and mortality in 21.4%.ConclusionsEndovascular treatment with AXS Catalyst 6 proved to be safe, technically feasible, and effective. Comparison analyses with other devices for mechanical thrombectomy are needed.

Recent randomized controlled clinical trials (RCTs) have revolutionized acute ischemic stroke care by extending the use of intravenous thrombolysis and endovascular reperfusion therapies in time windows that have been originally considered futile or even unsafe. Both systemic and endovascular reperfusion therapies have been shown to improve outcome in patients with wake-up strokes or symptom onset beyond 4.5 h for intravenous thrombolysis and beyond 6 h for endovascular treatment; however, they require advanced neuroimaging to select stroke patients safely. Experts have proposed simpler imaging algorithms but high-quality data on safety and efficacy are currently missing. RCTs used diverse imaging and clinical inclusion criteria for patient selection during the dawn of this novel stroke treatment paradigm. After taking into consideration the dismal prognosis of nonrecanalized ischemic stroke patients and the substantial clinical benefit of reperfusion therapies in selected late presenters, we propose rescue reperfusion therapies for acute ischemic stroke patients not fulfilling all clinical and imaging inclusion criteria as an option in a subgroup of patients with clinical and radiological profiles suggesting low risk for complications, notably hemorrhagic transformation as well as local or remote parenchymal hemorrhage. Incorporating new data to treatment algorithms may seem perplexing to stroke physicians, since treatment and imaging capabilities of each stroke center may dictate diverse treatment pathways. This narrative review will summarize current data that will assist clinicians in the selection of those late presenters that will most likely benefit from acute reperfusion therapies. Different treatment algorithms are provided according to available neuroimaging and endovascular treatment capabilities.

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.

Background: Recent trials have demonstrated a reduction in death or disability with endovascular treatment in patients with acute ischemic strokes. However, readmission rates and predictors are not known. Objective: To identify rates and factors associated with 30-day readmission after endovascular treatment in ischemic stroke patients. Methods: Nationwide Readmissions Data (NRD) between 2010 and 2017 was utilized to identify endovascular treatment in acute ischemic stroke patients using ICD-9 and ICD-10 codes. We used hierarchical logistic regression model to identify factors associated with 30-day readmissions. Results: Among 17, 562 acute ischemic stroke patients who survived to discharge after endovascular treatment, 2334 (13.29%) were readmitted within 30-days. Age => 65 years (odds ratio [OR]: 1.23, 95% confidence interval [CI]: 1.09 to 1.39, p =0.0005), chronic kidney disease (OR: 1.28, 95%CI: 1.12 to 1.47, p = 0.0004), congestive heart failure (OR: 1.25, 95%CI: 1.13 to 1.39, p <.0001), post procedure intracranial hemorrhage (OR: 1.09, 95%CI: 0.99 to 1.20, p = 0.04) and diabetes mellitus (OR: 1.09, 95%CI: 0.99 to 1.20, p = .09) during the index hospitalization were associated with readmission within 30 days. Conclusion: In this large nationally representative study, nearly one in 10 patients were readmitted within 30 days after discharge in acute ischemic stroke patients undergoing endovascular treatment. Medical comorbidities and post procedure intracranial hemorrhage were associated with 30-day readmission.

Įvadas. Sąmonės sedacija (SS) ir bendroji endotrachėjinė anestezija (BETA) – anestezijos metodai, taikomi mechaninės trombektomijos (MTE) metu. Tikslių rekomendacijų dėl anestezijos metodo pasirinkimo MTE metu nėra. Retrospektyviniai tyrimai teigia, kad BETA yra susijusi su blogesnėmis pacientų išeitimis, tačiau naujuose klinikiniuose tyrimuose tokio skirtumo nestebima. Darbo tikslas buvo nustatyti anestezijos metodo įtaką mechaninės trombektomijos efektyvumui ir saugumui ligoniams, patyrusiems ūminį išeminį insultą. Tiriamieji ir tyrimo metodai. Į tyrimą įtraukti dviejuose Vilniaus centruose gydyti ūminį išeminį insultą patyrę ligoniai, kuriems buvo atlikta MTE. Ligoniai suskirstyti į 2 grupes pagal taikytą anestezijos metodą: bendroji endotrachėjinė anestezija (BETA) ir sąmonės sedacija (SS). Abiejose grupėse vertinti demografiniai, klinikiniai ir logistiniai rodikliai. Pirminiu vertinimo kriterijumi pasirinkta gera baigtis po 24 valandų. MTE saugumas vertintas pagal 7 parų mirštamumą ir simptominių intrasmegeninių kraujosruvų (sISK) dažnį. Rezultatai. Į tyrimą įtraukta 248 pacientai. 105 pacientams (42,3 %) taikyta BETA ir 143 (57,7 %) – SS. Pagal pradines charakteristikas abi grupės statistiškai nesiskyrė, išskyrus prieširdžių virpėjimo dažnį (55,9 % – SS vs 37,1 % – BETA grupėje, p = 0,003) ir intraveninės trombolizės taikymą iki MTE (66,4 % – SS grupėje ir 46,7 % – BETA grupėje, p = 0,003). Gera baigtis po 24 val. nustatyta 51,4 % (n = 54) ligonių – BETA grupėje ir 58,7 % (n = 84) ligonių – SS grupėje (p = 0,252). 7 parų mirštamumo sISK dažnis abiejose grupėse statistiškai reikšmingai nesiskyrė. Regresinė analizė parodė, kad geros baigties nepriklausomi prognoziniai veiksniai yra laikas nuo atvykimo į stacionarą iki rekanalizacijos ir sėkminga rekanalizacija. Išvados. Anestezijos tipas nėra reikšmingas mechaninės trombektomijos efektyvumo ir saugumo veiksnys ankstyvai pacientų baigčiai. Siekiant tiksliau įvertinti anestezijos reikšmę mechaninės trombektomijos baigčiai ir nustatyti procedūros baigties prognozinius veiksnius, reikalingi papildomi atsitiktinės atrankos tyrimai.
