In the 1950s and 1960s, a scholar in Japan discovered a rare disease and named this rare disease smog, which was named because when the patient underwent cerebral angiography, the skull base showed many small dense piles of blood vessel shadows, resembling the smoke exhaled when smoking. Although the incidence of smog is relatively low and the domestic pathology is rare, the harm to people cannot be ignored, causing dizziness and headache, mental decline, hemiplegia, aphasia, etc., or brain hemorrhage and cerebral infarction threatening patients’ lives. So for smog disease must be early detection and early treatment, mentioned treatment. The cost of surgery depends on the specific condition of the patient, some need to do unilateral surgery, some need to do bilateral surgery, and the cost is not the same. In recent years, in the treatment of smog disease, the hospital has introduced a team of experts and professors from the aviation general hospital of China Medical University, a cross-regional medical association unit, to achieve technology sharing and unified standards, and has now matured to carry out joint vascular bypass surgery for smog disease. The team has performed nearly 1000 cases of combined vascular bypass surgery, the youngest of which is a 1-year-old child, which has been reported by many media such as Beijing News, Beijing TV and Tencent Video. The combined vascular bypass surgery is a new type of smog surgery, which is a double procedure of direct bypass + patching, completing two procedures at the same time on one surgery, rapidly improving the blood supply to the brain while expanding the scope of blood supply improvement, completing a more comprehensive and perfect blood flow reconstruction, with good postoperative results.
