Patient’s question: 11 years history of hypertension, blood pressure always controlled, dizziness for more than 10 years, otherwise normal. Only dizziness MRI and DSA were done, I would like to ask the doctor, what should I do in this case? Do I need surgery for the dizziness only? How about medication? Doctor’s reply: You can review the imaging regularly, if there is no bleeding, you can continue conservative treatment. The drugs used for the treatment of smog are vasodilators, antiplatelet drugs and anticoagulants, such as aspirin, ticlopidine and other drugs, which have some clinical efficacy, but the effectiveness of all lack of clinical trials to confirm. There are no effective drugs that can reduce the bleeding rate in patients with smog. Surgical treatment of smog is more effective than drug treatment, and surgery can be considered if the diagnosis is clear. Surgery can be divided into direct and indirect revascularization procedures. The current surgical approach is very inconsistent.
