Collateral circulation is the alternate circulation around a blocked artery or vein via another path, such as nearby minor vessels. It may occur via preexisting vascular redundancy (analogous to engineered redundancy), as in the circle of Willis in the brain, or it may occur via new branches formed between adjacent blood vessels (neovascularization), as in the eye after a retinal jikishinkobudo.com: D The survival of the brain regions at risk depends on a number of factors: the adequacy of collateral circulation, the state of the systemic circulation, serological factors, changes in the obstructing vascular lesion, resistance in the microcirculatory bed, and brain edema and intracranial pressure.
