Arterial embolism
Arterial Embolism
Arterial embolism (pronounced: ar-TEER-ee-al em-BOWL-izm) is a medical condition where a blood clot or other foreign substance travels through the bloodstream and becomes lodged in an artery, blocking blood flow.
Etymology
The term "arterial embolism" is derived from the Greek words "arteria" meaning air holder and "embolos" meaning plug or stopper.
Definition
An arterial embolism is a blockage in one of the arteries that prevents oxygen-rich blood from reaching the tissues. The blockage is usually a blood clot, but it can also be air, fat, or tissue.
Causes
The most common cause of an arterial embolism is a condition called atrial fibrillation, where the heart beats irregularly. Other causes can include heart disease, infection, or injury.
Symptoms
Symptoms of an arterial embolism can vary depending on where in the body the blockage occurs. Common symptoms include pain, swelling, and a pale or blue color in the affected area.
Treatment
Treatment for an arterial embolism usually involves medication to dissolve the clot, surgery to remove it, or procedures to improve blood flow around the blockage.
