Arterial occlusion
Arterial Occlusion
Arterial occlusion (/ɑːrˈtɪəriəl ɒkˈkluːʒən/) is a medical condition characterized by the blockage of an artery, often due to a blood clot or atherosclerotic plaque.
Etymology
The term "arterial occlusion" is derived from the Latin arteria, meaning 'windpipe, artery', and the Latin occlusio, meaning 'a shutting up'.
Definition
Arterial occlusion refers to the blockage or obstruction of an artery, typically by a blood clot or a buildup of fatty deposits known as atherosclerotic plaques. This can restrict blood flow to tissues and organs, potentially leading to damage or death of the affected tissues.
Causes
Arterial occlusion can be caused by a number of factors, including atherosclerosis, thrombosis, and embolism. Atherosclerosis involves the buildup of fatty deposits in the arteries, while thrombosis refers to the formation of a blood clot within a blood vessel. Embolism, on the other hand, involves a blood clot, air bubble, or other substance traveling through the bloodstream and lodging in an artery, causing a blockage.
Symptoms
Symptoms of arterial occlusion can vary depending on the location and severity of the blockage. They may include pain, swelling, and decreased temperature in the affected area, as well as potential tissue death if the blockage is not promptly treated.
Treatment
Treatment for arterial occlusion typically involves methods to remove or bypass the blockage, such as angioplasty, stent placement, or arterial bypass surgery. Medications may also be used to prevent further clotting or to dissolve existing clots.
