Brain stent surgery is required to go to a provincial first-tier hospital. The risk of stent placement in the brain is relatively high, and there is no need to consider taking the stent out again after surgery. The stent requires lifelong use of anticoagulants and the risk of brain hemorrhage increases. The survival rate after brain stent surgery is relatively high, and the specific procedure needs to depend on the condition of the patient’s brain hemorrhage in order to develop a treatment plan. The procedure is as follows: 1. sterilization and local anesthesia. 2. puncture. 3. establishment of access. 4. start of contrast. 5. balloon dilation. 6. implantation of stent. 7. incision dressing. At present, the technology of cerebrovascular stent placement is very mature, there is no risk of brain damage without general anesthesia, and it can be recovered quickly after the operation. Any operation is more or less risky, mostly from the specificity of the patient, and solid technology is the most important.
