Blockage of vertebral artery is more common in clinical practice, and its treatment is divided into conservative drug treatment and thrombolytic treatment. 1.Since vertebral artery provides posterior circulation to the brain, there are left and right sides, if the blockage is simply on one side or incomplete, you can use vasodilator drugs, anticoagulant drugs, plus drugs to stabilize the arterial plaque with treatment, such as aspirin enteric tablets, betahistine mesylate tablets, lovastatin tablets, so that the plaque is stabilized and does not continue to increase, so that the blood supply to the posterior circulation of the brain is not affected. 2.Thrombolytic treatment, if the blockage is more serious, and is detected earlier, then thrombolysis can be done, Lovastatin tablets, so that the plaque is stable and does not continue to increase the vasodilatation, so that the blood supply of the posterior circulation of the brain is not affected. 2. Thrombolytic therapy, if the blockage is more serious and discovered earlier, then thrombolytic therapy can be done, so that the plaque can disappear, which can change the blood supply of the vertebral artery to the greatest extent and improve the symptoms.
