As a rare disease, few people have heard of it, but it seems that the incidence of smog has been on the rise in recent years, and many patients are suffering from it. Smog is a cerebrovascular disease that causes abnormal blood supply to the brain and can lead to more serious problems if left untreated. The cause of smog is still unclear, and many patients feel baffled when they are diagnosed, not knowing how they got the disease. So, is there any heredity or intergenerational inheritance in smog? Some patients worry that their disease will be passed on to the next generation, so they may ask this question. In fact, from the very beginning, some scholars have found that smog does have a genetic predisposition, and there have been cases of intergenerational inheritance. Once diagnosed with smog, it is crucial to go to the hospital early to receive treatment. The course of smog is chronic and progressive, even if the symptoms are not too severe at first, it is important to treat the disease carefully to avoid worsening the problem. There is a consensus among medical experts that there is no specific drug for the treatment of smog, and that surgical treatment is generally more reliable. There are three main surgical methods: direct bypass, indirect bypass and combined vascular bypass surgery, but after a series of clinical verification, the first two methods still have certain limitations in treatment, and sometimes the recovery effect after surgery is not good, so it is recommended to choose combined vascular bypass surgery.
