Common sequelae of interventional brain surgery include reperfusion injury, cerebral hemorrhage, hemiplegia, cerebral infarction, and even if the procedure is successful, patients will still have some physical dysfunction, response dysfunction, and thinking or mental impairment. With the continuous improvement of overall neurointerventional treatment and advancement of treatment methods, the treatment of cerebrovascular diseases will be increasingly improved. Neurointerventional procedures are mainly applied to bleeding after intracranial aneurysm rupture, cerebral infarction, and intracranial vascular malformation. Neurological surgery itself is extremely risky, and any minor complications can lead to significant sequelae in patients.
