Congenital smog disease is a kind of vascular anomaly disease, which may lead to cerebral infarction, cerebral hemorrhage and other serious consequences, affecting the patient’s quality of life, and even leading to the patient’s death. 1. Cerebral infarction: congenital smoky disease is mainly manifested by the gradual narrowing and occlusion of the end of the large arteries, which leads to the compensatory proliferation of some small blood vessels in the surrounding area, thus leading to ischemia and hypoxia of some neural tissues, which leads to the occurrence of cerebral infarction. 2. Cerebral hemorrhage: mainly due to the compensatory proliferation of the surrounding small blood vessels can not withstand the pressure, resulting in rupture, which leads to the occurrence of cerebral hemorrhage. Congenital smoky mildew may lead to cerebral infarction and cerebral hemorrhage, which may lead to hemiplegia, speech disorder, epileptic seizures, and even sudden death, and it is a type of disease with higher risk. If you have congenital smoky syndrome, you should seek medical attention.
