Collateral blood vessel refer to a vessel that allows redundant blood supply to take more than one route to a given region. The term "collateral" describes redundant blood flow present in the vascular network after occlusion of an artery. If one vessel is blocked, a given region might be spared an infarct because the blood has an alternative route.
