Arterial occlusion occurs when a blood vessel, specifically an artery, becomes blocked, preventing blood from flowing to vital organs and tissues. This blockage can be caused by various factors, including blood clots, plaque buildup, or fatty deposits. When blood flow is restricted, it can lead to serious health issues, such as pain, tissue damage, or even organ failure. Symptoms of arterial occlusion may include chest pain, numbness, or weakness in the affected area. If not treated promptly, it can result in severe complications, such as a heart attack or stroke. Early detection and intervention are crucial for restoring blood flow and minimizing damage.
