Thank you for using this service. I want to add a few things that may answer your question also. I agree with Dr. PG's list of differential. However, since you stated that your symptoms are in both eyes, it leads me to think that you may have had a small stroke to the occipital lobe (this would cause you to lose peripheral vision in both eyes simultaneously) rather than an isolated problem to a single eye. This can only be confirmed with a visual field test and a CT. I agree with Dr. PG that you need to be seen by an ophthalmologist.
As to your original question, the thromboembolic risk with angioplasty is rare (much more rare than bleeding complications). Therefore thromboembolic medications are usually not given immediately after the procedure because bleeding is much more likely than a clot traveling up the vessels. After the immediate postop when the bleeding has stopped, patients are usually restarted on aspirin or other antiplatelet regimen.
Hope this helps some more and thank you.

I'm sorry. I've tried it twice and it worked both times.
