Smog is not related to haze and smog: Many people have never heard of smog, and those who first hear of it always tend to associate it with haze and smog. However, smog is not related to smog or haze, but it is a cerebrovascular disease that is very harmful to the human body. Many patients with smog have few symptoms in the early stages of the disease and only know they have the disease when they undergo some medical tests. Cerebral angiography is the gold standard for the diagnosis of smog: Is an angiogram needed for smog? Cerebral angiography is the gold standard for the diagnosis of smog. It can show the morphological structure of the blood vessels in the brain, clearly observe the location of the lesions and the localization of the stenosis, so as to develop a suitable treatment plan. program. Traditional treatment of smog is not ideal: In the treatment of smog, some hospitals take conservative medication, which is not only unable to cure smog fundamentally, but also brings some other side effects to the patient’s body. Therefore, the scientific treatment of smog requires further surgical procedures. The traditional surgical methods are simple bypass and simple patching, but these two methods are too single and the postoperative effect may not be very satisfactory. Combined vascular bypass surgery is effective: So, is there no good way to deal with smog? This technique combines patching and bypass surgery, which can establish a comprehensive system of blood flow, improve blood flow, and play a two-pronged role, and is a very advanced surgical procedure that can improve blood supply to the brain on a large scale and promote recovery.
