Patients with cerebral blood supply deficiency and cerebral vascular spasm can use vasodilator drugs appropriately, such as flunarizine hydrochloride and fasudil hydrochloride, and if the patient’s blood pressure is not low when monitoring blood pressure, nimodipine can also be applied appropriately. Insufficient cerebral blood supply can also be applied to improve microcirculation and activate blood circulation and remove blood stasis. Clinically, ginkgo biloba preparations, such as ginkgo biloba extract tablets, danhong injection, and injectable thromboxane, shuxin, etc., are commonly used to improve cerebral blood supply and relieve cerebral vascular spasm at the same time. If the patient’s symptoms are severe, they can be combined with drugs that improve microcirculation and vasodilatation, such as prostilbestrol. If cerebral vasospasm occurs in patients with cerebral insufficiency, patients should be given anti-platelet aggregation medication if necessary to avoid ischemic cerebral infarction. If a patient has a cerebral arteriosclerosis, he or she should be given antiplatelet aggregation or anticoagulation medication if necessary.
