Some areas in your body are supplied by more than one blood vessel. These extra vessels are called collateral blood vessels. For example, there is a major collateral vessel in the thigh. This is used by cardiologists to perform a heart bypass when the heart's own vessels are blocked.

Define the term collateral blood flow and describe how this and other factors affect the development of a stroke?
When a collateral vessel on the heart enlarges, it lets blood flow from an opencoronary artery to an adjacent one or further downstream on the same artery. In this way, collateral vessels grow and form a kind of "detour" around a blockage. This collateral circulation provides alternate routes of blood flow to the heart in cases when the heart isn't getting the blood supply it needs. When an artery in the brain is blocked due to stroke or transient ischemic attack (TIA), open collateral vessels can allow blood to "detour" around the blockage. This collateral circulation restores blood flow to the affected part of the brain.
When damaged hearts develop new blood vessels to nourish the area of the heart being starved for oxygen it is called?

What are collateral veins?
collateral veins are produced by your body when it thinks it is not getting sufficient circulation from a part of the body. If a part of your body is not returning blood back to the heart from a particular part of the body, your body will grow veins around that area to assisst in circulating the blood. Unfortunately these veins are usually thinner and less organized than the original venous structures. Spider veins are examples of collateral veins. There are collateral arteries as well. When a part of the body is not receiving enough oxygen new arteries will grow around to assisst in circulation. Like veins these are of poor structural quality too.
What are the limitations of the modified allen's test?
The modified Allen's test can produce false negatives or positives due to variation in collateral circulation between individuals. It may also be challenging to perform accurately, especially in patients with peripheral vascular disease, obesity, or tremors. Additionally, the test does not provide detailed information on the adequacy of collateral circulation beyond the assessment of ulnar artery patency.
What is the adaptation of the heart to allow blood flow to be redirected through other small vessels of the heart called?
The heart's natural ability to adapt by redirection is called collateral circulation.
