Brain aneurysm stents are generally used permanently for a number of years. 1. Cerebral aneurysm stents are designed to prevent the spring coil that embolizes the aneurysm from dislodging, and play a supporting and fixing role for the spring coil. It is generally used permanently. Once the stent is placed, it does not need to be removed, and anticoagulant drugs, such as aspirin, need to be taken consistently to prevent the formation of blood clots in order to maintain the normal function of the stent. 2. After stenting for cerebral aneurysm, cerebral angiography needs to be repeated in six months to one year to see if the spring coil and stent are functioning well. Patients with cerebral aneurysm stenting surgery are recommended to follow the doctor’s instructions for regular review and follow-up.
