How long does thrombolytic therapy for cerebral thrombosis usually take?
Disease description:
Recently, I heard that a relative was diagnosed with cerebral thrombosis, which upset me greatly. As a family member, I am very concerned and would like to ask the doctor: approximately how long does thrombolytic treatment for cerebral thrombosis take?

In general, the thrombolytic time window for cerebral thrombosis is approximately within 4.5 to 6 hours. Specifically:
The optimal time for thrombolytic therapy in cerebral thrombosis is usually within 4.5 hours after symptom onset. Within this time frame, thrombolytic treatment with alteplase can maximize blood flow restoration, reduce damage to the ischemic penumbra, and salvage ischemic brain tissue.
If a patient arrives at the hospital between 4.5 and 6 hours after symptom onset, although the optimal time window for recombinant tissue plasminogen activator (rtPA) thrombolysis has passed, the patient may still be eligible for treatment with other thrombolytic agents such as urokinase, which demonstrates relatively good efficacy within 6 hours.
However, thrombolytic therapy is not suitable for all patients with cerebral thrombosis. Its appropriateness must be evaluated based on factors including the patient's age, severity of symptoms, health status prior to the stroke, and imaging findings. Additionally, thrombolytic therapy carries certain risks, such as hemorrhagic transformation.
Furthermore, for patients with cerebral thrombosis beyond the thrombolytic time window, physicians may consider alternative treatment approaches, such as antiplatelet therapy, anticoagulant therapy, and others.
