Cerebral angiography is generally recommended at 6 months to 1 year after cerebral aneurysm surgery. In general, cerebral angiography should be repeated 6 months to 1 year after cerebral aneurysm intervention in order to observe whether there is blood filling in the aneurysm body, whether the neck of the aneurysm is healed, whether the spring coil is dislodged from the aneurysm, etc., as well as to check whether there are new aneurysms or arterial stenosis and other diseases in the cranium. If the aneurysm is still filled with blood, it can be disposed of according to its specific conditions, and it is recommended to review the cerebral angiography after 6 months, and if the aneurysm or the neck of the aneurysm is found to be poorly healed, a second surgical treatment can be chosen. Patients with cerebral aneurysm should follow the doctor’s instructions for follow-up treatment after surgery, and should consult the doctor promptly if any discomfort occurs.
