Early Complications of Endothelial Origin

Abstract

During HCT, the vascular endothelium is affected by conditioning, IS agents, inflammatory molecules released by injured cells and tissues, endotoxins translocated across injured mucosal barriers, the complex process of engraftment, and in allo-HCT immune alloreactivity. This endothelial damage can affect the entire vascular endothelium or that of specific organs and be the triggering event for several of the early complications grouped under denomination vascular endothelial syndromes of HCT.
