After stent intervention for cerebral artery stenosis, the following points need to be noted: (1) medication, after artery stenosis is put into stents, antiplatelet drugs must be taken, including (1) aspirin 100-300 mg each time, once a day, after meals (in order to reduce the side effects of stimulation of the digestive tract), it is generally recommended to take small doses of aspirin (100 mg) for life, small doses of aspirin have fewer side effects Smaller side effects are beneficial for patients with both cerebrovascular and cardiovascular sclerosis; (2) clopidogrel (trade name Bolivar, Tyga) 75mg each time, once daily, taken with aspirin for 6 weeks to 3 months after stenting (if a drug-eluting stent is placed, this drug is recommended for 1 year); (3) statins, (e.g. atorvastatin 20-40mg each time, or rasulvastatin 10-20mg once a night), statins 20mg once a night), statins have the effect of stabilizing plaque and reducing restenosis in addition to lowering lipids, so you cannot stop statins based on whether your blood lipids are high or low. (4) Blood pressure control, generally hypertensive patients need to lower to below 140/90, and patients with diabetes need to lower to below 130/85; 2. Healthy lifestyle, which is especially important, including quitting smoking, controlling blood sugar to treat diabetes, lowering blood lipids to avoid high-fat diet, weight control, and proper exercise. 3, there is a sudden onset of hemiplegia, aphasia, partial body numbness, unstable walking, black haze, facial palsy and other cerebral ischemic symptoms need to immediately call 120 and immediately go to the hospital emergency room. 4. Pay attention to the observation of discharge summary and regular review at the outpatient clinic to detect the emergence of restenosis in the stent or new stenosis in other parts in time. Total support, although the stent placement can reduce the occurrence of stroke, but need the cooperation of many other aspects to obtain long-term good results.
