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.

Multimodal Ct

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: 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 and Purpose: Clot fragmentation and distal embolization during endovascular thrombectomy for acute ischemic stroke may produce emboli downstream of the target occlusion or in previously uninvolved territories. Susceptibility-weighted magnetic resonance imaging can identify both emboli to distal territories (EDT) and new territories (ENT) as new susceptibility vessel signs (SVS). Diffusion-weighted imaging (DWI) can identify infarcts in new territories (INT). Methods: We studied consecutive acute ischemic stroke patients undergoing magnetic resonance imaging before and after thrombectomy. Frequency, predictors, and outcomes of EDT and ENT detected on gradient-recalled echo imaging (EDT-SVS and ENT-SVS) and INT detected on DWI (INT-DWI) were analyzed. Results: Among 50 thrombectomy-treated acute ischemic stroke patients meeting study criteria, mean age was 70 (±16) years, 44% were women, and presenting National Institutes of Health Stroke Scale score 15 (interquartile range, 8–19). Overall, 21 of 50 (42%) patients showed periprocedural embolic events, including 10 of 50 (20%) with new EDT-SVS, 10 of 50 (20%) with INT-DWI, and 1 of 50 (2%) with both. No patient showed ENT-SVS. On multivariate analysis, model-selected predictors of EDT-SVS were lower initial diastolic blood pressure (odds ratio, 1.09 [95% CI, 1.02–1.16]), alteplase pretreatment (odds ratio, 5.54 [95% CI, 0.94–32.49]), and atrial fibrillation (odds ratio, 7.38 [95% CI, 1.02–53.32]). Classification tree analysis identified pretreatment target occlusion SVS as an additional predictor. On univariate analysis, INT-DWI was less common with internal carotid artery (5%), intermediate with middle cerebral artery (25%), and highest with vertebrobasilar (57%) target occlusions ( P =0.02). EDT-SVS was not associated with imaging/functional outcomes, but INT-DWI was associated with reduced radiological hemorrhagic transformation (0% versus 54%; P <0.01). Conclusions: Among acute ischemic stroke patients treated with thrombectomy, imaging evidence of distal emboli, including EDT-SVS beyond the target occlusion and INT-DWI in novel territories, occur in about 2 in every 5 cases. Predictors of EDT-SVS are pretreatment intravenous fibrinolysis, potentially disrupting thrombus structural integrity; atrial fibrillation, possibly reflecting larger target thrombus burden; lower diastolic blood pressure, suggestive of impaired embolic washout; and pretreatment target occlusion SVS sign, indicating erythrocyte-rich, friable target thrombus.
