. As a result of subendothelial collagen exposure,
tissue factor is activated increasing the risk for thrombotic
events to occur (99,100). In addition, inhibiting VEGF causes
reduction in nitric oxide and prostacyclin, as well as increases
hematocrit and blood viscosity via overproduction of erythropoietin,
all of which may predispose patients to an increased
risk of thromboembolic events
