Direct vascular bypass surgery is a minimally invasive, fast-acting and effective treatment. It is an effective treatment especially for patients with early detection or mild smoldering disease. The incision is small, usually 5-6 cm in size, and the bone flap is only about 2.5 cm, which is only slightly larger than a normal appendicitis incision. Most patients can be out of bed about 3 days after surgery. In addition, this direct vascular bypass procedure still takes into account the reversal of the dural posture at the same time. According to our clinical observation of more than 100 cases, it is a recommended treatment method. Qi Hui, Department of Neurosurgery, Peking University Shenzhen Hospital
