Severe stenosis of the middle cerebral artery needs to be treated with stent surgery. Middle cerebral artery stenosis can be treated with conservative medication in mild and moderate cases, but when the condition reaches a severe level, the main symptom is insufficient blood supply to the brain, and in more serious cases, it can lead to cerebral infarction, and if it causes damage to the functional areas, it can lead to favoritism, aphasia, etc. At this time, the effect of medication is no longer satisfactory, and stenting is needed to treat the condition. Stenting, also known as coronary stenting, involves implanting a balloon catheter through a vascular puncture into a narrowed blood vessel. The balloon is pressurized and inflated outside the body to open up the narrowed blood vessel wall, restoring the diseased blood vessel, and is a treatment to prevent acute occlusion of the coronary arteries. After stent surgery, you generally need to take long-term anti-platelet drugs, such as aspirin, and you need to strictly control blood lipids, blood pressure, avoid smoking, drinking alcohol, and if you suffer from diabetes, you also need to strictly control your blood sugar. These factors can lead to stenosis again after stent surgery, but also to work and rest regularly, avoid staying up late, and maintain an optimistic mood. Patients should follow the doctor’s instructions and actively cooperate with the doctor’s treatment, so as not to delay the condition or cause adverse reactions.
