Contrast-Associated Nephropathy Risk Evaluation in Acute Ischemic Stroke After Endovascular Thrombectomy
- Conditions
- Contrast-Associated Acute Kidney Injury
- Registration Number
- NCT06596603
- Lead Sponsor
- Niguarda Hospital
- Brief Summary
The CAN-REST study is a multicenter, observational, and retrospective study aimed at evaluating the incidence and risk factors of contrast-associated acute kidney injury (CA-AKI) in patients with acute ischemic stroke (AIS) who undergo endovascular thrombectomy (EVT). This study is conducted across multiple centers in Italy, Europe, the USA, and Canada, and includes data from AIS patients treated with EVT in 2023. The primary objectives are to assess the incidence of CA-AKI in this population and identify associated risk factors. Secondary objectives include evaluating the impact of CA-AKI on clinical outcomes, such as the length of hospital stay, functional recovery, and 90-day mortality, as well as developing risk stratification tools to predict CA-AKI. By analyzing a large cohort of patients, CAN-REST aims to provide critical insights into the renal complications associated with EVT and establish predictive models that can guide clinical decision-making and improve patient outcomes.
- Detailed Description
The CAN-REST study is a multicenter, observational, and retrospective study designed to evaluate the incidence and risk factors of contrast-associated acute kidney injury (CA-AKI) in patients who have suffered an acute ischemic stroke (AIS) and subsequently underwent endovascular thrombectomy (EVT). The use of contrast agents during EVT, essential for visualizing blood vessels and guiding the procedure, poses a risk for CA-AKI, particularly in patients who are already in a vulnerable state due to stroke-related comorbidities and the acute nature of their condition.
The primary objective of the study is to assess the incidence of CA-AKI in AIS patients following EVT and to identify specific risk factors that contribute to the development of CA-AKI. Secondary objectives include evaluating the impact of CA-AKI on clinical outcomes, such as the length of hospital stay, functional recovery as measured by the modified Rankin Scale (mRS) at discharge and 90 days post-procedure, and all-cause mortality at 90 days. Additionally, the study aims to develop and validate risk stratification tools that can predict the likelihood of CA-AKI based on both baseline patient characteristics and procedural variables related to EVT.
The study population consists of all consecutive AIS patients treated with EVT in participating centers from January 1, 2023, to December 31, 2023. Data collection will include detailed information on patient demographics, clinical history, stroke severity, procedural details of EVT, and subsequent renal function assessments to determine the development of CA-AKI. Two predictive models will be developed: one using only pre-EVT variables and another incorporating EVT-related variables to better stratify patients according to their risk for developing CA-AKI.
By analyzing a large cohort of patients from multiple centers worldwide, CAN-REST aims to provide valuable insights into the renal complications associated with the use of contrast media in EVT for AIS patients. The study's findings are expected to guide clinical practice by identifying high-risk patients and enabling the development of preventative strategies, ultimately improving patient outcomes and care standards in stroke treatment.

- Primary Outcome Measures
Name Time Method Incidence of Contrast-Associated Acute Kidney Injury (CA-AKI) Within 48 hours and up to 7 days post-endovascular thrombectomy. Measure the occurrence of acute kidney injury characterized by an increase in serum creatinine ≥0.3 mg/dL or ≥50% within 48 hours, or an increase of ≥0.3 mg/dL within 7 days post-endovascular thrombectomy in acute ischemic stroke patients.
- Secondary Outcome Measures
Name Time Method Days of In-Hospital Stay Measured daily from hospital admission until the day of discharge post-endovascular thrombectomy, assessed up to 30 days Measure the total number of days patients remain hospitalized following endovascular thrombectomy
Functional Recovery (modified Rankin Scale, mRS; ranging from 0 [full recovery] to 6[death]) 90 days post-procedure Assess the level of disability or dependence in daily activities of patients post-stroke, measured at discharge and at 90 days post-procedure
All-Cause Mortality at 90 Days (modified Rankin Scale, mRS = 6) 90 days post-procedure Measure the number of deaths from any cause within 90 days following endovascular thrombectomy Time Frame: 90 days post-procedure.
Development of Risk Stratification Tools 24 hours, 48 hours, at 3 months, and at 12 months post-endovascular thrombectomy Create and validate predictive models for CA-AKI using baseline and EVT-related variables to categorize patients into risk groups (low, medium, high)
