Decreased platelets (leading the DIC), hemolysis (rupture of red blood cells)leading to HELLP Syndrome: the damaged endothelial cells cause red blood cells to rupture and it causes the body to want to repair the cellsso platelets start to congregate at these cells (note in severe cases there are many damaged endothelial cells in the body so that requires a lot of platelets)this depletes the platelet stores and cause micro-clot development with the vessels, which decreases perfusion even more.
