Arterial occlusions occur when a blood vessel 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 embolism. When an artery is occluded, it can lead to serious health issues, such as heart attacks or strokes. Symptoms of arterial occlusions may include pain, numbness, or weakness in the affected area. Diagnosis typically involves imaging tests like ultrasound or angiography to visualize the blockage. Treatment options may include medications, lifestyle changes, or surgical procedures to restore blood flow.
