Official Title: Kidney and Intestinal Markers for Early Detection of Organ Injury After Endovascular Aortic Repair - The KISMED Study
Brief Summary:
This study aims to investigate the predictive value of novel biomarkers and contrast-enhanced ultrasonography for early detection of abdominal end-organ (kidney and intestinum) hypoperfusion and ischemia in patients undergoing endovascular aortic repair (EVAR) for aortic aneurysm or dissection. In this context, patients will be monitored for renal biomarkers (TIMP-2, IGFBP7) and intestinal biomarkers (plasmatic intestinal fatty acid binding protein (i-FABP)) and local tissue perfusion will be assessed using contrast-enhanced ultrasonography (CEUS).
The ultimate goal of this study is an early identification of patients developing one or both of these complications, which may facilitate a timely intervention to improve outcome.
Detailed Summary:
Sponsor: University Hospital Regensburg
Current Primary Outcome: Level of biomarkers of abdominal organ injury (plasmatic i-FABP, TIMP-2, IGFBP7) [ Time Frame: 48hours post surgery ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Local tissue perfusion and microcirculation as quantified by CEUS [ Time Frame: 48 hours post surgery ]
- Incidence of acute kidney injury (AKI) [ Time Frame: first 48 hours post surgery ]Incidence of AKI within the first 48 hours as based on current KDIGO/AKIN recommendation (Kidney Disease Improving Global Outcomes - Clinical Practice Guideline for Acute Kidney Injury)
- Localization and incidence of intestinal ischemia [ Time Frame: first 48 hours post surgery ]
Original Secondary Outcome: Same as current
