It is unlikely that a cerebral thrombosis stent will fall out. Cerebral thrombosis stent is due to blood vessel stenosis more than 70%, in the process of the procedure if the blood vessel is found to be narrowed, the stent needs to be placed in the narrowest part of the blood vessel through the pressure to make the stent and the blood vessel wall fit, in this case, the stent is generally not dislodged. After stent implantation for cerebrovascular disease, medications such as aspirin, clopidogrel and other anti-platelet aggregation, simvastatin, atorvastatin and other plaque stabilizers should be used as prescribed by the doctor. After the stent is put in, the medication should be used according to the doctor’s prescription. Normal activities will not affect the stent, but if there is any discomfort, please consult the doctor in time.
