When these vessels become narrowed or occluded under the influence of some factors, a rare disease that endangers human health is formed, and this rare disease is called smog. There are two peak periods for smog to affect people: children under 10 years old and adults around 40 years old. Children usually present with weakness of limbs, mouth twitching, hemiplegia, headache, and even epilepsy. So, does childhood smoker’s disease continue to develop after surgery? There are six stages in the development of smoker’s disease. The first stage is the stenosis of the end of the internal carotid artery, involving both sides; the second stage is the dilation of the main arteries in the brain and the appearance of smoker’s vessels at the base of the brain; the third stage is the further aggravation of the stenosis and the more obvious smoker’s vessels; the fourth stage is the appearance of the lateral branch circulation outside the skull and the reduction of smoker’s vessels; the fifth stage is the further development of the disease; the sixth stage is The sixth stage shows complete occlusion of the internal carotid artery and the disappearance of smoldering vessels. In conclusion, the progression of smoldering disease in stages 1-6 shows a stepwise aggravation, especially for children, early detection and early treatment are more beneficial to recovery. Effective surgical treatment for smog: Combined vascular bypass surgery is a surgical procedure to reconstruct the blood vessels and improve the symptoms of cerebral ischemia for the purpose of treating smog. The unique advantage of this procedure is that it is a rare double combination of direct bypass and indirect patching in one procedure, which makes the procedure more effective. For children with smog, after surgical treatment, the progression of the disease can be better stopped, the brain is no longer ischemic, and the smoggy vessels will not continue to develop.
