Patients with cerebral thrombosis can be treated with thrombolysis, but there are certain indications and contraindications for thrombolysis, which must be mastered. Intravenous thrombolytic drugs can be used within 6 hours of the onset of thrombolysis. Intravenous thrombolytic drugs mainly include rtPA for intravenous thrombolysis within 4.5 hours of onset, and urokinase for intravenous thrombolysis between 4.5 and 6 hours. Thrombolysis requires the patient’s age to be older than 18 years old, the family to sign an informed consent, and the patient to be diagnosed with ischemic cerebral infarction with clear symptoms of neurological deficits to be given thrombolysis. There are many contraindications to thrombolysis, which must be clearly understood. Patients with cerebral hemorrhage or subarachnoid hemorrhage, intracranial tumors, arteriovenous malformations, aneurysms, or patients with severe head trauma, cerebral infarction, active bleeding in the past 3 months, or patients with bleeding tendency, such as low platelet count and coagulation disorders, should not be given thrombolysis for These patients cannot be treated with thrombolysis.
