Neutrophil gelatinase-associated lipocalin (NGAL) and endothelial progenitor cells (EPCs) evaluation in aortic aneurysm repair.
Acute kidney injury (AKI) develops in 10% of patients after surgical abdominal aortic aneurysm (AAA) repair. Neutrophil gelatinase-associated lipocalin (NGAL) is a predictor of AKI and Endothelial Progenitor Cells (EPCs) represent a potential repair mechanism for vascular lesions. We evaluated the diagnostic power of serum (s) and urine (u) NGAL in detecting a possible event of AKI in patients undergoing surgical treatment for AAA repair. We also investigated the influence of vascular injury on EPCs. ⋯ NGAL represents an independent renal predictor of incidence of AKI. EPCs reflect the degree of vascular damage and could be considered as an indicator of disease with a reparative-regenerative vascular-endothelial function.
