At present, with the development of science and technology and the progress of imaging, more and more cases of intracranial aneurysm are found clinically, and the unexpected discovery of unruptured aneurysm also adds much burden to patients, while the means of treating aneurysm also appears to be diversified, and the surgical indications of traditional craniotomy to clip aneurysm are re-evaluated, and with the development of material science, endovascular intervention for intracranial aneurysm has developed rapidly in recent years, so that it gives patients a lot of confusion. Which is better: surgery or intervention? Intracranial aneurysm is a special disease, each patient is different, the shape, size and location of the aneurysm are different, the treatment means are also different, the conditions of each hospital are also different, some aneurysms can only be operated, some aneurysms can only be interventional, and some aneurysms can be both operated and interventional, depending on the conditions of different hospitals. It also depends on the skill level of the doctor. Aneurysms are neurosurgical conditions that may require further surgical management after surgery, whether open or interventional. In addition, regarding the treatment of unruptured aneurysms, I take a cautious approach. If the aneurysm is well handled, choose intervention, and if it is difficult to handle a complex aneurysm, evaluate whether the aneurysm is prone to rupture? Treatment must be cautious, otherwise catastrophic consequences are to occur.
