I had TIAs 5 days ago. The CT scan showed that I had complete occlusion of the origin of the anterior cerebral artery. What are my options?

Prevention. 1. Have your doctor check for numerous risk factors such as hypertension, hyperlipemia, diabetes, inflammation or arteries, hyperhomocysteinemia, cardiac disease, carotid stenosis, chance of emboli from distant source. In general if no emboli would use combination of Aggrenox and a statin for prevention.
Not many. Once the vessel is occluded for a length of time, it cannot be reopened. Best to do now is prevention . .
