Every family member suffering from an intracranial aneurysm is faced with this question, should it be a traditional craniotomy or an intervention? In this field, it is also the focus of controversy for many scholars. Due to the development of imaging computers and materials, the development of interventional therapy is changing day by day. Most of the scholars think that the effect of that kind of treatment should be based on the specific condition, and quite a number of aneurysms are suitable for craniotomy and interventional embolization, but from the morphological analysis, the embolization of middle cerebral artery aneurysm is more difficult and is more suitable for craniotomy, and it is easier to deal with the embolization of the aneurysm of posterior circulation artery and aneurysm of cavernous sinus and internal carotid artery segments. 2009 edition of the American guidelines of the SAH treatment Requirements: the choice of treatment should be based on the patient, the aneurysm and the hospital to analyze the three aspects of the comprehensive factors to decide, so the consensus of foreign neurosurgeons: not all aneurysms are suitable for embolization, and surgical clamping can not solve all aneurysms. At present, the interventional treatment of aneurysms is developing rapidly and the technology is very mature, and families are very receptive to the reality of treating aneurysms without craniotomy. Intervention has been able to solve most of the patients with aneurysms. Advantages: safe, less traumatic, faster recovery and other advantages. Disadvantages: high technical requirements, expensive cost, general aneurysm cost about 50,000 yuan, multiple, complex aneurysms cost about 100,000 yuan. Patients who are older, weaker, have serious organic diseases, and cannot afford craniotomy are more likely to choose interventional therapy. Complicated aneurysms, vascular variations, and aneurysms that are difficult to send catheters for imaging are more suitable for craniotomy. The maturity of current interventional technology makes the treatment of intracranial aneurysms faster and safer.
