Tx for COMPLETE (**100%**) occlusion of the carotid artery / asymptomatic patient correct
answers risks of CEA outweigh its benefits b/c absence of sx indicates the presence of adequate
collateral blood flow. Medical therapy only.

What % stenosis in carotid artery atherosclerosis is needed for any management. correct answers
>50% stenosis needs management which includes medical therapy in ALL patients and
evaluation for carotid endarterectomy (CEA) for SELECT patients.

Define symptomatic in carotid artery atherosclerosis correct answers TIA or ischemic stroke in
the distribution (ie on the correct side) of the affected vessel within the past 6 months

CEA is recommended correct answers In patients who have:
-a life expectancy >5 years AND
-are symptomatic from a high-grade lesion, eg, 70%-99%
(symptomatic = ie, transient ischemic attack or ischemic stroke in the distribution of the affected
vessel within the past 6 months)

Patients unlikely to benefit from CEA correct answers -those who have significant comorbidities,
ie, poor surgical candidates;
, -those who have had an ipsilateral stroke with persistent disabling neurologic deficits;
-those with COMPLETE "100%" OCCLUSION of the internal carotid artery.

Patients not benefiting from Carotid Endarterectomy (CEA): correct answers Patients not
benefiting from Carotid Endarterectomy (CEA):
1. significant comorbidities;
2. complete (100%) occlusion of the internal carotid artery;
3. hx ipsilateral stroke with persistent disabling sequelae.
