About 70% of the brain’s blood supply comes from the carotid artery, which shows the importance of the carotid artery. The carotid artery can be considered the lifeblood of a person, and once a lesion occurs, it can cause many serious hazards. If the carotid artery is narrowed, it is easy to block the blood vessels, resulting in the obstruction of blood supply to the brain tissue and the lack of blood supply to the brain, leading to cerebral infarction, so we must pay attention to carotid stenosis. What medications should I take for the lack of blood supply to the brain caused by carotid stenosis? Pharmacological treatment of carotid stenosis mainly refers to anti-platelet aggregation drugs, which aim to stabilize atherosclerotic plaques and minimize thrombosis, thus reducing the occurrence of cerebral ischemic events. Drug treatment is generally applicable to patients with stenosis rate below 50%, and it is recommended to go to a regular hospital to take targeted treatment under the guidance of professional doctors. In addition to drug treatment, surgery is also a common clinical treatment for carotid artery stenosis, generally for those with stenosis greater than 50% and symptomatic, as well as those with stenosis greater than 70%, with the aim of fundamentally removing the plaque and restoring blood flow to the brain tissue. Carotid endarterectomy has proven its effectiveness in removing atherosclerotic plaque and preventing cerebral infarction through a large number of clinical cases. Carotid plaque is like an “unscheduled bomb” quietly buried in the human body, threatening our health all the time, but fortunately, it can be prevented. In daily life, patients must develop good living and eating habits, exercise properly, control weight, avoid obesity, quit smoking, drink less alcohol, and reasonably control blood pressure, blood sugar and blood lipids.
