The term "Collateral Circulation" refers to the alternative route through which blood can flow in case the main artery is blocked. It is spelled as /kəˈlæt ər əl/ /ˌsɜr kjuˈleɪ ʃən/. The first two syllables are pronounced as "kuh-lat" with emphasis on the first syllable. The third syllable is "er" and the fourth syllable is "al" pronounced as "uh-ler-uhl". The second part of the word, "circulation", is pronounced as /ˌsɜr kjuˈleɪ ʃən/. This term is usually used in the medical field to describe blood flow in the body.
Collateral circulation refers to the alternative or backup system of blood vessels that can develop or be utilized in response to a blockage or narrowing of a blood vessel in the body. It serves as a natural mechanism to maintain blood flow and supply to tissues or organs when the primary blood vessels supplying them become compromised.
In normal circumstances, blood flows through a network of blood vessels that are specifically designed to reach specific organs and tissues. However, in certain situations, such as a clot obstructing a blood vessel or the gradual accumulation of plaque narrowing it, blood flow can be impeded. This reduced blood flow may result in tissue damage, oxygen deprivation, or organ dysfunction.
Collateral circulation acts as a safety net in such cases. When there is a blockage or restriction in a blood vessel, collateral vessels gradually expand and develop to establish an alternate pathway for blood to flow around the obstruction. This rerouting allows the affected tissue or organ to continue receiving blood supply, to varying degrees, and make up for the reduced or obstructed circulation.
Collateral circulation is considered a natural process but can also occur as a result of medical interventions or treatments aimed at improving blood flow to a specific region of the body. It can be facilitated through interventions like bypass surgery, angioplasty, or stenting, which help to create new pathways for blood to flow.
The development and extent of collateral circulation can significantly vary between individuals and depends on various factors like genetics, existing blood vessel architecture, and the severity and duration of the underlying obstruction. Researchers and medical professionals study collateral circulation to better understand its potential role in treating or preventing diseases related to inadequate blood flow.
The term "collateral circulation" originated from the combination of two separate words: "collateral" and "circulation".
The word "collateral" has its roots in the Latin word "collaterālis", which means "side by side" or "with the side". It is formed by combining "col-" (meaning "together" or "with") and "-laterālis" (meaning "side" or "pertaining to the side").
The second word, "circulation", has Latin roots as well. It comes from the Latin word "circulāre", meaning "to circulate" or "move around in a circle". This word is derived from the noun "circulus", which means "circle" or "ring".
