Revascularization therapy carries the risk of hemorrhagic transformation, with the incidence of symptomatic hemorrhagic transformation after thrombolysis ranging from 2% to 7%. The thrombolytic drug alteplase (rt-PA) also has the potential to cause angioneurotic edema. Overall, however, the benefits of revascularization therapy outweigh the risks, and medical staff will closely monitor changes in the condition and take appropriate measures to prevent and treat complications during treatment.
