There are not many statistics on the success rate of thrombolysis in cerebral infarction, which is about 30%. The benefits of thrombolysis in cerebral infarction are more in the following aspects: early restoration of interrupted blood supply, shortening the duration of ischemic damage, reducing the infarcted area of cerebral infarction, restoring reversibly damaged ischemic tissue, and improving neurological function. The success rate of thrombolysis for cardiogenic embolism with complete recanalization is on the low side, and the risk of late bleeding is relatively high. For cerebral thrombosis caused by atherosclerotic plaque formation in situ, the effect is still relatively good, such as the appearance of unfavorable limb movement, clumsy language, and the recovery of symptoms after thrombolysis is still very good, and the time window for thrombolysis of vertebrobasilar artery thrombosis can be appropriately relaxed again.
