The review items after cerebral aneurysm intervention include: 1. the most common is the review of vital signs, and the patient’s blood pressure is the most critical; 2. head CT to understand whether the current closed status of the aneurysm has caused secondary cerebral infarction or cerebral hemorrhage; 3. the most important review items are still magnetic resonance angiography and CT angiography; 4. in the middle of all these imaging processes, the current The gold standard is still whole brain angiography. However, the only gold standard is the whole brain angiography with postoperative 3D imaging and post-processing, which can understand whether the stent, spring coil and aneurysm have formed a close relationship, and whether the stent, spring coil and aneurysm have formed a close relationship. Whether a tight relationship is formed in the middle, embolic density, embolic strength, etc., which is helpful to determine whether intracranial aneurysms have recurrence after surgery. If there is recurrence, whether these recurrent conditions need to be treated and by which means to perfect the treatment, the most authoritative conclusion should be reached by whole brain angiography.
