”Rare smog disease!” Generally speaking, people who first hear about smog disease do not know whether it is serious or not, and can only learn about the disease through their own search or doctor’s referral. Smog is a rare cerebrovascular disease that is indeed little known in China. However, in recent years, the incidence of the disease has been increasing, and it is slowly becoming better known to the public, and treatment methods for it are improving. Conservative treatment of smog is not very beneficial and can only alleviate the symptoms at the moment, but not the root cause of the disease. In the end, surgery is needed, but many patients cannot help but be afraid and worried when they hear that smog is a craniotomy, and not only patients but also their families are afraid of the risks and mistakes that can be made during the craniotomy process, fearing the inevitable consequences. Cutting an incision in the scalp sounds like a scary thing, so is smog bypass surgery minimally invasive? In fact, the combined vascular bypass surgery that can effectively treat smog is not a kind of surgery that is minimally invasive, but the surgeon finds the anastomosed blood vessel from the surface of the brain during the operation, and from this perspective, the risk of this surgery is not as high as we think. In fact, the risk of surgery comes from the intraoperative and postoperative blood pressure management, induction and awakening of anesthesia, which is very important, but as long as we can choose the right professional team, do a good job of close cooperation, and do a good job of preoperative evaluation and postoperative care, there are usually no major problems. Combined vascular bypass surgery has treated many smog patients since it was carried out, and the procedure has been recognized by the public for its low risk and high efficiency.
