Cerebral aneurysm interventions are usually discharged from the hospital after one to two weeks, but may take longer if there is more bleeding and other symptoms develop. Cerebral aneurysm intervention surgery is now very mature and less invasive. The main procedure is to insert a cannula from the femoral artery at the root of the thigh, and deliver an embolus through the catheter to the aneurysm to embolize it. Generally speaking, the operation is faster and more effective. If the aneurysm does not bleed or bleeds less, it can be recovered within one to two weeks after active treatment, and can be discharged from the hospital if there is no other complication. However, if the cerebral aneurysm ruptures and bleeds a lot, other symptoms such as headache, nausea and vomiting or even coma may occur, and the treatment time will be prolonged. It is recommended that patients actively cooperate with doctors for follow-up treatment after cerebral aneurysm intervention surgery, and the specific discharge time can be consulted with physicians.
