An arterial embolism is a blood clot that has become lodged in the arterial blood system, the main circulatory system for delivering oxygenated blood. This can restrict vital blood flow in tissues and organs virtually anywhere in the body. However, blood clots in the arterial circulatory system tend to affect the arms, legs, or feet in the majority of cases.

If cellular tissue is devoid of oxygen for a long period of time, it will lead to tissue damage and cell death in the affected area. Arterial blood clots are considered a medical emergency and require immediate attention.

A blood clot (thrombus) not only restricts blood flow, but also has the potential to break apart, forming emboli; a free-floating blood clot with the potential to block blood supply elsewhere.
