if stenosis is <60% we followup but if >60% we perform CEA.

But when do we use ASA and when do we use heparin..in Carotid artery disease...its very confusing.

thanks.

ASA-------------is used as first line prevention for acute ischemic stroke and has been shown to reduce morbidity and mortality in atherosclerotic stroke . If patient is allergic to ASA or had a stoke while on ASA , use dypiramidole or clopidrogrel .

Heparin -------- used only in acute ischemic stroke in patients with higher risk of recurrent stroke like AF , basilar artery thrombosis and stroke in evolution because of the risk of intracranial hemorrhage

Carotod endarterectomy ----- if occlusion is more 70 % and symptomatic

Any input is WELCOME !

thanks Doc_clotaire,

Just one thought...if stroke is in evolution by giving heparin won't we increase the risk of hmge? thanks.

You are welcome nikki !

I agree with you that there is a slight increase risk of hemorrhage if patient is having a stroke in evolution but I think the risk of this adverse effect is offset by the benefit of the treatment .
