The length of life of a patient with cerebral thrombosis cannot be generalized, but must be determined in the context of the severity of the patient’s condition. Generally speaking, patients with mild cerebral thrombosis usually do not affect their life expectancy, while patients with severe cerebral thrombosis survive from several months to several years. The survival of patients with mild cerebral thrombosis will not be affected if the limb strength of the patient is still fine, and if the patient can adhere to exercise, take oral medication on time, and do a good job in secondary prevention of cerebrovascular disease and delay the redevelopment of cerebrovascular disease through active treatment in the hospital during the acute period, and after discharge. However, patients with severe cerebral thrombosis and bedridden limb paralysis are prone to complications such as pneumonic pneumonia, urinary tract infection, arterial and venous thrombosis of lower limbs, and decubitus ulcers, which can seriously threaten patients’ life safety. Therefore, such patients with improper care and poor nutrition can be life-threatening within a few months; however, patients with proper care, few complications, and active control of risk factors can have their survival extended to some extent to several years or longer. Patients with cerebral thrombosis should actively control cerebrovascular disease risk factors and change poor lifestyle habits to avoid recurrence of serious cerebrovascular disease events.
