Arterial thrombosis is a medical condition where a blood clot, or thrombus, forms in an artery, blocking blood flow. This can occur in various arteries, including those supplying the heart, brain, or limbs. When blood flow is restricted, it can lead to serious complications, such as a heart attack or stroke. The formation of an arterial thrombus can be triggered by factors like atherosclerosis, where fatty deposits build up in the arteries, or by injury to the blood vessel. Risk factors include high blood pressure, high cholesterol, smoking, and certain medical conditions, such as diabetes. Prompt treatment is essential to restore blood flow and prevent damage to affected organs.
