Cerebrovascular intervention is the application of special instruments to produce imaging results of the whole cerebral vasculature through the femoral artery, usually the right common carotid artery and the left common carotid artery and aorta are selected. When performing cerebral angiography, CT or MRI is required to verify the target organ and to predict whether the patient has infarcts, aneurysms, hemangiomas, and other diseases, and then special instruments are selected for application, including spring coils, stents, etc. Embolization is performed by applying silicone, filling by applying spring coils, and embolization by applying stents.
