Is there sequela in cerebral aneurysm interventional operation

Interventional surgery for cerebral aneurysms. If the surgery is successful, the postoperative recovery is good, and generally there will be no sequelae. If the surgery is wrong, or the postoperative recovery is poor, there will be some sequelae, such as hemorrhage, cerebral infarction, hemiplegia, hydrocephalus, aphasia and epilepsy.
