What term refers to arterial thrombosis that may cause tissue damage due to lack of blood supply?

The term that refers to arterial thrombosis that may cause tissue damage due to lack of blood supply is ischemia. Ischemia occurs when there is an insufficient blood flow to a tissue, leading to a deficiency in the oxygen and nutrients that are crucial for cellular metabolism and function. This lack of adequate blood supply can result in tissue damage or necrosis if not resolved in a timely manner.

When thrombosis occurs in an artery, it blocks the normal blood flow, creating an ischemic environment. The tissues downstream from the blockage may not receive enough oxygen and nutrients, which can lead to cellular injury or death. Recognizing ischemia is essential in clinical settings, as timely intervention can prevent irreversible damage to the affected tissues.

In contrast, the other terms represent different concepts:

• An embolism refers to a blood clot or other debris that travels through the bloodstream and lodges in a vessel, obstructing blood flow.
• Hemorrhage describes bleeding or the escape of blood from the circulatory system, which is not directly related to a lack of blood supply to tissues due to blockage.
• Hyperemia refers to an excess of blood in a given tissue, often due to increased blood flow, which is the opposite of what occurs in ischemia.
