With the development of medical science, the diagnosis and treatment technology of neurosurgery has made great progress. The particularity of nerve tissue in anatomy and physiology requires us to make not only the localization diagnosis, but also the qualitative diagnosis; It not only needs special surgical operations such as cutting, hemostasis and repair, but also needs solid theoretical foundation and diagnosis and treatment skills. At present, there are still many complex problems in neurosurgery, which have become prominent problems affecting human health, population quality and quality of life. Cerebrovascular disease is a common and major disease threatening human health in the world. With the development of modern society, although medical science continues to progress and various diagnosis and treatment technologies continue to innovate, there are still a large number of critically ill patients in this professional field, and the mortality and disability rates are still high. Therefore, the developed countries all over the world attach great importance to the diagnosis and treatment of cerebrovascular disease, and our government also attaches great importance to the research in this field. The rapid development of neurosurgery in hospitals at all levels, the maturity and popularization of DSA and CT angiography, and the establishment and operation of professional intensive care unit will bring strong technology and facilities guarantee for the treatment of such patients.Cerebrovascular disease is one of the common diseases that endanger people's health. It has a high incidence rate and disability rate, which causes great burden to patients and even to society. Therefore, the prevention, treatment, etiology and pathogenesis of cerebrovascular should be popularized and improved. The diagnosis and treatment of cerebrovascular disease is an indispensable and important aspect in neurosurgery. The patients with cerebrovascular disease are diverse and complex. In the treatment process, multi-disciplinary knowledge and multidisciplinary cooperation are needed, including the treatment of basic metabolism, treatment of intracranial hypertension, treatment of cerebrovascular disease, support of respiratory function, monitoring of cardiopulmonary function, and various surgical operations. To save the lives of patients and further improve the quality of life is the goal of our treatment. Our country has a solid foundation in this field of clinical and research, and has accumulated a lot of clinical experience. However, compared with advanced countries, the utilization of resources is not enough, the close cooperation between multi disciplines is not mature enough, and the academic atmosphere of clinical research is not active enough. All these need to be further improved
