Flow is Reestablished Rapidly During the Extravasation Process Allowing Vessel Survival. (a) In arterioles > 20 μm in diameter, blood flow is reestablished, at least partially, even before complete embolus extravasation given that multiple rows of cells can circulate simultaneously. (b) In capillaries, blood flow is generally reestablished following complete embolus translocation.Reprinted by permission from Macmillan Publishers Ltd: Nature (Lam CK, Yoo T, Hiner B, et al.
