What are the indications of carotid endarterectomy

summary

My aunt used carotid endarterectomy for treatment, mainly suffering from carotid artery disease, although the recovery effect is very good, but the use of this kind of operation must be guaranteed to meet the indications. Let's look at the indications of carotid endarterectomy.

What are the indications of carotid endarterectomy

First, patients with unilateral transient ischemic attack of carotid system and severe stenosis of ipsilateral internal carotid artery (the degree of stenosis is more than 50% of the original diameter, or the diameter of residual diameter is less than 2mm) showed by carotid angiography.

Secondly, carotid endarterectomy should be performed at least on the symptomatic side if there are symptoms of unilateral carotid TIA and severe stenosis of bilateral internal carotid arteries. Contralateral carotid endarterectomy should be performed after 4 weeks, or it can be omitted.

Finally: Patients with unilateral carotid system TIA attack symptoms, ipsilateral internal carotid artery stenosis is not serious, but there are atherosclerotic plaque or ulcer formation, it is estimated that these lesions may be the cause of TIA or transient amaurosis, after carotid endarterectomy can avoid repeated attacks.

matters needing attention

If the symptoms worsen after the operation, we should think that there is thrombosis in the operation site. Cerebral angiography is feasible. If it is confirmed that there is thrombosis obstruction, we should use the operation to remove the thrombosis as soon as possible and carry out anticoagulation treatment.
