Acute kidney injury (AKI) is often associated with the use of contrast agents. We evaluated the frequency of AKI, factors associated with AKI after endovascular treatment (EVT), and associations with AKI and clinical outcomes. We retrospectively analyzed consecutively enrolled patients with acute ischemic stroke who underwent EVT at three stroke centers in Korea. We compared the characteristics of patients with and without AKI and independent factors associated with AKI after EVT. We also investigated the effects of AKI on functional outcomes and mortality at 3 months. Of the 601 patients analyzed, 59 patients (9.8%) developed AKI and five patients (0.8%) started renal replacement therapy after EVT. In the multivariate analysis, diabetes mellitus (odds ratio (OR), 2.341; 95% CI, 1.283–4.269; p = 0.005), the contrast agent dose (OR, 1.107 per 10 mL; 95% CI, 1.032–1.187; p = 0.004), and unsuccessful reperfusion (OR, 1.909; 95% CI, 1.019–3.520; p = 0.040) were independently associated with AKI. The presence of AKI was associated with a poor functional outcome (OR, 5.145; 95% CI, 2.177–13.850; p < 0.001) and mortality (OR, 8.164; 95% CI, 4.046–16.709; p < 0.001) at 3 months. AKI may also affect the outcomes of ischemic stroke patients undergoing EVT. When implementing EVT, practitioners should be aware of these risk factors.

Background: Acute ischemic stroke patients are at risk of acute kidney injury (AKI) due to volume depletion, contrast exposure and pre-existing co-morbid diseases. We determined the incidence and identified predictors associated with AKI in acute ischemic stroke patients. Methods: Data from the Albumin in Acute Ischemic Stroke trial (ALIAS) - I and II and Interventional Management of Stroke (IMS) - III clinical trials were pooled and analyzed in which acute ischemic stroke patients were randomized into either IV albumin, placebo, endovascular or IV thrombolytic treatment groups. Serum creatinine levels from baseline and within day 5 or discharge along with the demographic and comorbidity information was collected. AKI classification was used to ascertain severity of renal dysfunction and based on increase in serum creatinine levels from baseline, stage 1 ≥ 0.3 mg/dl (≥ 26.4umol/L) or (>1.5 to 2-fold), stage 2 (>2 to 3-fold) and stage 3 (>3-fold) were identified. We analyzed the relationship between AKI and mortality at 3 months post randomization. Results: A total of 1931 acute ischemic stroke patients (mean age 66± 13 (SD) years; 1024 were men) were analyzed. Any increase in serum creatinine was seen in 691 (35.8%, 95% CI 30%-40%) and AKI was seen in 68 (3.5%, 95% CI 3%-4%) of 1931 patients. Severity of AKI was grade I, II, III in 2.1 %, 0.4%, and 0.1% patients, respectively. The risk of AKI was not higher between those who either underwent CT angiography (2% compared with 4.2%, RR 0.5, 95% CI 0.3-0.8, p=0.02) or endovascular treatment (1.9% compared with 4.1%, RR 0.4, 95% CI 0.2-0.8, p=0.0096). Patients with preexisting hypertension (4.3% compared to 1.5%, RR 2.8, 95% CI 1.3-5.7, p=0.006) and preexisting renal disease (9.1% compared to 3.0%, RR 3.1, 95% CI 1.8-5.3, p=0.006) had higher risk of AKI. Mortality at 3 months was significantly higher among patients with AKI (27% compared with 15%, RR 1.8, 95% CI 1.2-2.7, p=0.0083). Conclusions: The incidence of AKI in acute ischemic stroke patients was low and was not higher in patients who underwent CT angiogram or those who received endovascular treatment. Occurrence of AKI increased mortality at 3 months among acute ischemic stroke patients.

Background: Endovascular treatment involves cerebral angiography with injection of contrast agents that are nephrotoxic and carry risk of renal failure. Our objective was to determine the incidence and identify predictors associated with acute kidney injury in ischemic stroke patients undergoing endovascular treatment. Materials and methods: Data from the Interventional Management of Stroke (IMS) - III clinical trial was utilized in which acute ischemic stroke patients were randomized into endovascular or intravenous treatment groups. Baseline and day 5 or discharge serum creatinine levels along with the demographic and comorbidity information was collected. Acute Kidney Injury classification was used to ascertain severity of renal dysfunction and based on increase in Day 5 creatinine levels from baseline, stage 1 (1.5 to 2 fold), stage 2 (>2 to 3 fold), and stage 3 renal failure (>3 fold increase from baseline) were identified. Results: Total of 434 patients received ET and 222 patients received intravenous treatment (IVT) with tissue plasminogen activator (tPA). Increase in serum creatinine levels was observed in 52 patients (12%) receiving ET and 24 patients (11%) in the IVT group. Renal failure (stage 1 or higher) was observed in 5 patients (1.2%) in the ET group and 3 patients (1.4%) in the IVT group. In univariate analysis, only age was associated with higher incidence of renal failure in the ET group. No significant association was observed with comorbid diagnoses, particularly pre-existing hypertension or diabetes mellitus. Baseline creatinine level was associated with renal failure (p=0.029) in patients receiving ET and pre-existing diagnosis of renal disorders was associated with renal failure in patients receiving IVT. Conclusions: In the IMS III data, incidence of acute kidney injury in acute ischemic stroke was low and was not different from patients receiving IVT.

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.

Abstract Introduction The existence of the smoker’s paradox is controversial and potential mechanisms have not been explained. We aimed to explore the association between cigarette smoking and functional outcome at 3 months in patients with acute ischemic stroke who were treated with intravenous thrombolysis (IVT) or endovascular treatment (EVT). Methods This meta-analysis was conducted in accordance with the PRISMA guidelines. Studies exploring the association between smoking and good functional outcome (modified Rankin Scale score ≤ 2) following IVT or EVT were searched via the databases of PubMed, Embase, and the Cochrane Library from inception to August 8, 2018. Information on the characteristics of included studies was independently extracted by two investigators. Data were pooled using a random-effects or fixed-effects meta-analysis according to the heterogeneity of included studies. Results Among 20 identified studies, 15 reported functional outcomes following IVT, and five reported functional outcomes following EVT. Unadjusted analyses showed that smoking increased the odds of good functional outcomes with a pooled odds ratio (OR) of 1.48 (95% confidence interval [CI]: 1.36–1.60) after IVT and 2.10 (95% CI: 1.47–3.20) after EVT. Of IVT studies, only eight reported outcomes adjusted for covariates and none of the EVT studies reported adjusted outcomes. After adjustment, the relation between smoking and good functional outcome following IVT lost statistical significance (OR 1.14 [95% CI: 0.81–1.59]). Conclusion Our meta-analysis suggested that smoking was not associated with good functional outcome (mRS ≤ 2) at 3 months in patients with acute ischemic stroke who were treated with intravenous thrombolysis. Implications The existence of the smoker’s paradox is controversial. A previous letter by Plas et al. published in 2013 reported a positive result for the association between smoking and good functional outcome at 3 months in acute ischemic stroke patients who received intravenous thrombolysis (IVT). However, a major limitation of their meta-analysis was that the process of data synthesis was based on unadjusted data. Therefore, we conducted this meta-analysis to investigate the association based on adjusted data and a larger sample size. Our meta-analysis suggested that smoking was not associated with good functional outcome after adjusting for covariates.

Background and Purpose: We aimed to compare outcome of endovascular thrombectomy in acute ischemic stroke in patients with and without cerebral amyloid angiopathy (CAA). Methods: We included patients with and without possible or probable CAA based on the modified Boston criteria from an observational multicenter cohort of patients with acute ischemic stroke and endovascular thrombectomy, the German Stroke Registry Endovascular Treatment trial. We analyzed baseline characteristics, procedural parameters, and functional outcome after 90 days. Results: Twenty-eight (17.3%) of 162 acute ischemic stroke patients were diagnosed with CAA based on iron-sensitive magnetic resonance imaging performed before endovascular thrombectomy. CAA patients were less likely to have a good 90-day outcome (14.3 versus 37.8%). National Institutes of Health Stroke Scale score (adjusted odds ratio, 0.88; P <0.001), successful recanalization (adjusted odds ratio 6.82; P =0.005), and CAA (adjusted odds ratio 0.28; P =0.049) were independent outcome predictors. Intravenous thrombolysis was associated with an increased rate of good outcome (36.3% versus 0%, P =0.031) in CAA. Conclusions: Endovascular thrombectomy with or without thrombolysis appears beneficial in acute ischemic stroke patients with possible or probable CAA, but is associated with a worse functional outcome.

Background. Multimodal computed tomography (CT) guides decision-making regarding use of thrombolytic agents in acute ischemic stroke patients. However, postcontrast acute kidney injury (PC-AKI) is a potential adverse effect of the contrast media used, which may require hemodialysis and cause a longer hospital stay. The incidence and risk factors of PC-AKI in acute ischemic stroke patients, particularly in Thailand, remain unclear. Goal. We aimed at determining the incidence and risk factors of PC-AKI in patients with acute ischemic stroke undergoing multimodal CT. Methods. We conducted a retrospective review of Thai acute ischemic stroke patients admitted to the King Chulalongkorn Memorial Hospital between January 2014 and December 2017 who received multimodal CT and thrombolytic treatment with alteplase. Result. Overall, 109 patients were included for analysis; eight patients (7.3%) developed PC-AKI. Estimated glomerular filtration rate eGFR≤30 mL/min and mechanical thrombectomy were risk factors significantly associated with PC-AKI. Conclusion. The incidence of PC-AKI in a real practice setting did not differ from previous reports. Two factors were associated with PC-AKI, eGFR≤30 mL/min and mechanical thrombectomy. Patients without these risk factors may not need to wait for the results of renal function testing prior to multimodal CT.

Background Preoperative neuroimaging assessment of collateral circulation is important for selecting acute ischemic stroke patients who are appropriate for endovascular treatment. We sought to validate the capillary index score system in an Asian population and compare its ability in predicting clinical outcomes with the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology grading system. Methods We continuously enrolled acute ischemic stroke patients from two neurological centers from March 2014 to March 2017. Multivariate analyses were performed to assess the capillary index score system with 90-day clinical outcome (modified Rankin scale score). The scoring systems were compared for predicting good (modified Rankin scale 0–2) and excellent (modified Rankin scale 0–1) functional outcomes using area under the receiver operating characteristic curves. Results We identified 157 patients (median age, 65 years; 96 (61.1%) males), of whom 71 (45.2%) patients with 90-day good functional outcomes were selected. Capillary index score was independently associated with clinical outcome after endovascular treatment (OR 0.63; 95% CI 0.43–0.92; P = 0.016) with its predictive ability for good functional outcome (area under the receiver operating characteristic curve 0.755). For excellent functional outcome, the capillary index score system was not inferior to the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology grading system (area under the receiver operating characteristic curve 0.748 versus 0.793, P = 0.09). Conclusions The capillary index score system is a potentially useful tool for predicting 90-day functional outcomes in acute ischemic stroke patients after endovascular treatment.
