Smoke disease is a relatively rare cerebrovascular disease. It is called smoke disease because it causes morphological changes in the cerebral blood vessels, narrowing or occlusion of the main cerebral arteries, resulting in impaired blood supply, and then causes compensatory hyperplasia of the penetrating arteries at the base of the skull, forming a network of small, fragile, smoke-like vessels, hence the name smoke disease. One is the narrowing and occlusion of the main cerebral arteries, causing insufficient blood supply to the brain, resulting in some ischemic symptoms, and in severe cases, cerebral infarction, such as dizziness and headache, numbness and weakness of the limbs, some visual impairment, unclear language, etc. On the other hand, the smoke-like vessels formed at the base of the skull have very thin and fragile walls, and may rupture at any time, resulting in cerebral hemorrhage, with symptoms such as severe The symptoms can include severe headache, sudden unfavorable limb movement, and even syncope. Cerebral infarction and cerebral hemorrhage are both very dangerous and have a high rate of disability and death. Therefore, once smog is detected and diagnosed, it must be treated with surgery. Some patients are concerned about the pain of bypass surgery for smog. In recent years, modern medical conditions have been improving, and intraoperative anesthesia and inhalation are well controlled, so there is basically no pain during surgery. After the surgery, there will also be close control and care, and the patient will return to normal soon after the surgery, and there will be no pain. Combined vascular bypass surgery is a very advanced and effective surgical procedure for the treatment of smog, which can improve the ischemia of the patient’s brain and effectively prevent cerebral hemorrhage, achieving the ideal treatment effect. Moreover, with the team’s strict and systematic preoperative, intraoperative and postoperative control care, there is no pain either.
