"Endarterectomy" Natural Recordings by Native Speakers
Endarterectomy is a surgical procedure that involves removing the inner lining of an artery (endothelium) and the fatty deposits (plaque) that have accumulated on the inside of the artery wall. The goal of the procedure is to improve blood flow to the affected area by clearing away blockages and restoring the natural diameter of the artery. It is typically performed to treat occlusive peripheral artery disease, which occurs when fatty deposits and cholesterol build up in the arteries, reducing blood flow to the legs, feet, or other organs.
Endangered refers to a species, population, or ecosystem that is at risk of becoming extinct due to various factors such as habitat destruction, pollution, overhunting, climate change, and other human activities. An endangered species is one that is threatened with extinction and is in danger of disappearing from the face of the earth.
Endarterial refers to a type of blood vessel that has been thrombosed (clotted) or occluded (blocked) to the extent that its lumen (inner cavity) has been severely narrowed or occluded, but has not been completely removed or replaced. In other words, an endarterial structure is one that contains some residual lumen, but is mostly filled with blood clot or other obstructive material. This term is often used in surgical contexts, particularly during procedures that aim to restore blood flow to damaged or occluded vessels.
