Can you tell me more about cervical carotid artery dissection?

Separation. of layers of carotid artery. Stroke is the major risk. Depending on location and extent may be treated by blood thinners, surgery or stent placement.
Dissection. Majority caused by trauma. Initial therapy is heparinization and conversion to Coumadin (warfarin) with close follow up. Need full anticoagulation for minimum 3-6 months. Majority of dissections healed without sequela.
