An arterial occlusion is a localized embolism or atherosclerosis in the diameter of an artery that results in a blockage or lack of blood flow in that localized vessel. The cause of arterial occlusion is usually a blood clot. Prolonged hypertension, hyperlipidemia, or cardiovascular disease may cause the blood to thicken or the local tissue to detach and form an embolus. The prolonged retention of the embolus at the site of the primary lesion can cause chronic vascular obstruction. If a dislodged thrombus occurs, it may cause acute vascular obstruction during blood flow. Current treatment methods for arterial occlusion mainly include thrombolysis and interventional therapy, which can maximize the smooth flow of blood by dissolving or removing the embolus to restore the blood vessel to an open state. When choosing a specific treatment, it is necessary to differentiate between them in relation to the symptoms of vascular occlusion. In case of early arterial occlusion or high risk diseases such as hypertension and hyperlipidemia, one should go to the hospital in time for relevant examinations and follow the doctor’s instructions for the next step of treatment.
