The danger of cerebrovascular disease people have more or less heard of, of course, there are many types of cerebrovascular disease, smog disease is one of the rare one, really heard of smog disease few people, and in the suddenly told to suffer from smog disease, the patient is very alarmed, for the treatment of smog disease they do not know what to do. In fact, smog disease is also called cerebrovascular malformation disease, mainly patients with cerebral arterial ring bilaterally the main branches of the blood vessels appeared chronic progressive stenosis or occlusion, and then the skull and brain bottom appeared a lot of newborn abnormal blood vessel network, because of the imaging results look like smoke, so it is called smog disease. There are two types of smoky disease in the clinic, namely ischemic smoky disease and hemorrhagic smoky disease, ischemic smoky disease will be more slow onset, patients with insufficient blood supply to the brain as the main manifestation of the serious cases can lead to cerebral infarction; while the onset of hemorrhagic smoky disease is more acute, the symptoms are more intense, the danger of the more serious, and if necessary, need to be timely surgical drainage or removal of hematomas, to reduce the damage. Can I get better after surgery for brain hemorrhage caused by smog disease? The bleeding situation of smog disease is very critical, after surgery to control the bleeding symptoms, or to arrange smog disease bypass surgery as soon as possible, so as to prevent the recurrence of stroke and cerebral hemorrhage, and now the main surgical methods are direct bypass surgery, patch surgery and combined vascular bypass surgery these three kinds of surgery. However, after clinical practice, the previous two surgical methods are relatively single, such as direct bypass to improve the blood supply to the brain is limited; patch surgery after surgery blood vessel formation time is too long, during which there is a risk of stroke, etc., so in comparison, or combined vascular bypass surgery is more ideal.
