Vascular occlusion
Vascular Occlusion
Vascular occlusion (pronunciation: vas-kyuh-lahr oh-kloo-zhuhn) is a medical term referring to the blockage of a blood vessel.
Etymology
The term originates from the Latin vasculum, meaning "small vessel", and the Latin occlusio, meaning "a shutting up".
Definition
Vascular occlusion is a condition characterized by the blockage or obstruction of a blood vessel, often due to a blood clot or atherosclerosis. This can prevent blood flow to tissues and organs, potentially leading to damage or death of the affected tissues.
Types
There are several types of vascular occlusion, including:
- Arterial occlusion: This occurs when an artery is blocked, often due to a blood clot or atherosclerosis. This can lead to conditions such as stroke or heart attack.
- Venous occlusion: This occurs when a vein is blocked, often due to a blood clot. This can lead to conditions such as deep vein thrombosis or pulmonary embolism.
Related Terms
- Thrombosis: The formation of a blood clot inside a blood vessel, which can lead to vascular occlusion.
- Embolism: The sudden blockage of a blood vessel by an embolus (a blood clot or other foreign substance), which can lead to vascular occlusion.
- Ischemia: A condition in which the blood supply to a part of the body is cut off, often due to vascular occlusion.
- Infarction: The death of tissue due to a lack of blood supply, often caused by vascular occlusion.
