What does brain smog mean and what kind of disease is it? When you first hear the name smog, many people are unfamiliar with it, and it is easy to think that it may be caused by smoke in the air, or by smoking. In fact, the name smog is derived from the fact that cerebral angiograms show many small, dense piles of blood vessels that look like smoke from smoking, hence the name smog. Is it a major disease? Yes, it is a very rare cerebrovascular disease that causes malformation of blood vessels in the brain for various reasons, and if left untreated for a long time, it can easily lead to cerebral hemorrhage and cerebral infarction, so we must pay attention to smog disease as early as possible. Smoke disease first appeared in Japan in 1961, nowadays the incidence is not high in the world, and the relative treatment methods are also very limited, however, through the exploration and research of our medical experts, a new door has been opened for the treatment of smoke disease, and the most advanced “joint vascular bypass” in Japan was introduced into China, and After repeated clinical practice in China, we improved this technique and developed this leading and effective complex surgery in China. Can I be reimbursed for the combined vascular bypass surgery by medical insurance and agricultural cooperative? This is the concern of many smog patients and their families. First of all, doctors will have different treatment plans according to the patient’s condition, and the cost of surgery will be decided according to each patient’s situation. Secondly, patients can be assured that they can enjoy normal medical insurance policies in regular hospitals. Up to now, nearly 1,000 cases of smog patients have been recovered through combined vascular bypass surgery.
