Patient: The patient is 80 years old. In May this year, his family observed that he could not hold chopsticks steadily and his speech was unclear, and he was diagnosed with cerebral infarction after he went to the hospital and underwent an MRI examination, and the blockage area reached 75% of the left hemisphere of the brain. After infusion and medication, chopsticks can be held steadily, but there are still clinical manifestations of dizziness and mild speech impairment, is it suitable for angiography and stent surgery? Doctor: Usually, for patients who are 80 years old, I no longer recommend further interventional examinations and treatment. The risk associated with surgery increases with age. You said that the MRI found an infarct area of 75%, is it a stenosis of 75%? Did you do an MRI plain scan or angiography? Patient: My grandfather had an MRI and had carotid stenosis, which is now basically treated with medication. As a junior, I always want to maximize my elders’ recovery, but the problem now is that it is risky, so for the time being, he is still mainly treated conservatively with medication. Doctor: Listening to your description, I feel that the patient is generally in good condition and the quality of life is not bad. Our principle is that the better the patient’s current condition is, the more we advocate stent implantation treatment. Although relatively few stents are implanted in patients over 80 years old, it is not impossible to do so. We have done carotid artery stenting in 93-year-old patients. Moreover, with the current development of technology and materials, carotid stenting is now very mature and safe, and it is a trustworthy procedure. The above can only talk about the surgery, if conservative treatment, it is more necessary to have a detailed understanding of the physiological indicators of the elderly, in order to propose a detailed, thorough and targeted prevention and treatment plan. For example, blood pressure, blood lipids, blood sugar, platelets, red blood cells, coagulation indicators, liver and kidney function, digestive tract, nutritional status, lifestyle, eating habits, drinking habits, emotions, exercise and many other aspects of reasonable and correct intervention. Conservative treatment involves all aspects, which are clearly not adequately communicated here. Don’t always pin your hopes on some miracle drug; there is no drug with miraculous efficacy. Imagine an elderly person of 80 years of age with severely degraded and impaired body functions, it is impossible to bring back the old man with one or two drugs!
