Clinically, there is no so-called fastest way to open the blood supply to the brain, if there is severe cerebral stenosis or acute cerebral infarction, the main way to make the blood vessels reopen is through thrombolytic therapy, interventional therapy and other ways. 1. Interventional surgery: When cerebrovascular stenosis is found to be more than 70% by angiography, or when it reaches 50% but clinical symptoms have already appeared, stent implantation and other interventional surgeries can be chosen to recanalize the blood vessels. 2. Thrombolytic therapy: When acute cerebral infarction occurs, the blood vessels are occluded, and the blood vessels can be reopened through thrombolytic therapy. Representative drugs include reteplase, alteplase and so on. If there is acute cerebrovascular disease, it is recommended that patients should go to the neurology clinic of the hospital in time, improve the relevant auxiliary examinations under the guidance of the doctor to clarify the cause of the disease, and choose the treatment plan according to the patient’s condition individually, and do not treat blindly on your own, so as to avoid delaying the condition.
