Large artery infarction: thrombotic strokes are caused by occlusions on atherosclerotic lesions in the carotid, vertebrobasilar, and cerebral arteries. Small infarcts located in the deeper parts of the brain or in the brain stem. Result from occlusion of the smaller penetrating branches of large cerebral arteries. Treatment of ischemic stroke tpa ( tissue plasminogen activator) very effective in treating acute ischemic stroke. Medications for management: : anticoagulation ( warfarin, dabigatran, antiplatelet ( asa, clopidogrel, ticopidine, reperfusion (t-pa) Acute phases of ischemic stroke-- thrombolytic therapy may be administered within 3 hours to dissolve clot . Dissolves the clot and improves blood flow to the part of the brain.
