BackgroundCombining non-contrast CT (NCCT), CT angiography (CTA), and CT perfusion (CTP) imaging (referred to as a CT stroke study, CTSS) provides a rapid evaluation of the cerebrovascular axis during acute ischemic stroke. Iodinated contrast-enhanced CT imaging is not without risk, which includes renal injury. If a patient's CTSS identifies vascular pathology, digital subtraction angiography (DSA) is often performed within 24–48 h. Such patients may receive multiple administrations of iodinated contrast material over a short time period.ObjectiveWe aimed to evaluate the incidence of acute kidney injury (AKI) in patients who underwent a CTSS and DSA for evaluation of acute ischemic symptoms or for stroke intervention within a 48 h period between August 2012 and December 2014.MethodsWe identified 84 patients for inclusion in the analysis. Patients fell into one of two cohorts: AKI, defined as a rise in the serum creatinine level of ≥0.5 mg/dL from baseline, or non-AKI. Clinical parameters included pre- and post-imaging serum creatinine level, time between CTSS and DSA, and type of angiographic procedure (diagnostic vs intervention) performed.ResultsFour patients (4.7%) experienced AKI, one of whom had baseline renal dysfunction (defined as baseline serum creatinine level ≥1.5 mg/dL). The mean difference between baseline and peak creatinine values was found to be significantly greater in patients with AKI than in non-AKI patients (1.65 vs −0.09, respectively; p=0.0008).ConclusionsThis study provides preliminary evidence of the safety and feasibility of obtaining CTSS with additional DSA imaging, whether for diagnosis or intervention, to identify possible acute ischemic stroke.

Background and Purpose: Clinical outcome and mortality after endovascular thrombectomy (EVT) in patients with ischemic stroke are commonly assessed after 3 months. In patients with acute kidney injury (AKI), unfavorable results for 3-month mortality have been reported. However, data on the in-hospital mortality after EVT in this population are sparse. In the present study, we assessed whether AKI impacts in-hospital and 3-month mortality in patients undergoing EVT.Materials and Methods: From a prospectively recruiting database, consecutive acute ischemic stroke patients receiving EVT between 2010 and 2018 due to acute large vessel occlusion were included. Post-contrast AKI (PC-AKI) was defined as an increase of baseline creatinine of ≥0.5 mg/dL or >25% within 48 h after the first measurement at admission. Adjusting for potential confounders, associations between PC-AKI and mortality after stroke were tested in univariate and multivariate logistic regression models.Results: One thousand one hundred sixty-nine patients were included; 166 of them (14.2%) died during the acute hospital stay. Criteria for PC-AKI were met by 29 patients (2.5%). Presence of PC-AKI was associated with a significantly higher risk of in-hospital mortality in multivariate analysis [odds ratio (OR) = 2.87, 95% confidence interval (CI) = 1.16–7.13, p = 0.023]. Furthermore, factors associated with in-hospital mortality encompassed higher age (OR = 1.03, 95% CI = 1.01–1.04, p = 0.002), stroke severity (OR = 1.05, 95% CI = 1.03–1.08, p < 0.001), symptomatic intracerebral hemorrhage (OR = 3.20, 95% CI = 1.69–6.04, p < 0.001), posterior circulation stroke (OR = 2.85, 95% CI = 1.72–4.71, p < 0.001), and failed recanalization (OR = 2.00, 95% CI = 1.35–3.00, p = 0.001).Conclusion: PC-AKI is rare after EVT but represents an important risk factor for in-hospital mortality and for mortality within 3 months after hospital discharge. Preventing PC-AKI after EVT may represent an important and potentially lifesaving effort in future daily clinical practice.

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 and Purpose: While an association between hyperchloremia and worse outcomes, such as acute kidney injury and increased mortality, has been demonstrated in hemorrhagic stroke, it is unclear whether the same relationship exists after acute ischemic stroke. This study aims to determine the relationship between moderate hyperchloremia (serum chloride ≥115 mmol/L) and acute kidney injury in patients with ischemic stroke. Methods: This is a multicenter, retrospective, propensity-matched cohort study of adults admitted for acute ischemic stroke. The primary objective was to determine the relationship between moderate hyperchloremia and acute kidney injury, as defined by the Acute Kidney Injury Network criteria. Secondary objectives included mortality and hospital length of stay. Results: A total of 407 patients were included in the unmatched cohort (332 nonhyperchloremia and 75 hyperchloremia) and 114 patients (57 in each group) were matched based upon propensity scores. In the matched cohort, hyperchloremia was associated with an increased risk of acute kidney injury (relative risk 1.91 [95% confidence interval 1.01-3.59]) and a longer hospital length of stay (16 vs 12 days; P = .03). Mortality was higher in the hyperchloremia group (19.3% vs 10.5%, P = .19), but this did not reach statistical significance. Conclusions: In this study, hyperchloremia after ischemic stroke was associated with increased rates of acute kidney injury and longer hospital length of stay. Further research is needed to determine which interventions may increase chloride levels in patients with acute ischemic stroke and the association between hyperchloremia and clinical outcomes.
