The survival time of vascular blockage in the brain is influenced by several factors, such as the size of the blockage point and the location of the blockage. In addition, the timeliness of treatment and the number of complications also affect the survival time of patients and cannot be uniformly determined. When a blood vessel in the brain is blocked, some people die immediately, some die after a few days or weeks, but some people can survive for life. If the blockage is small, such as a small lacunar infarction, it is usually not life-threatening after aggressive treatment; if the blockage is large and is a key site, such as a blockage in the middle cerebral artery or the main vertebral basilar artery, the mortality rate is higher and the patient’s life is always in danger. Meanwhile, if the condition can be thrombolized about 3-5 hours after the attack, or after arterial embolization treatment about 16-24 hours, the blocked blood vessel is opened and the recovery is better, which may not affect the survival rate of the patient; if the patient is not rescued in time and serious sequelae occur, such as hemiplegia and bedridden, which increase the chance of complications, such as lung infection, urinary tract infection, pressure sores, etc., the survival time of the patient is reduced . In addition, if patients have no serious sequelae and recover well after treatment, they also need to do a good job in secondary prevention of ischemic cerebrovascular disease, such as active antiplatelet, lipid lowering, blood pressure lowering, blood sugar control and lifestyle changes, etc. When the risk factors are effectively controlled, the survival time of patients can also be unaffected.
