Typically, 3 out of 10 of these patients have an instable plaque inside a blood vessel that is obstructing the flow of blood through the arteries that supply the head.
This blockage is the major cause for their stroke. This plaque with local thrombosis can cause a further stroke by cerebral embolisation.
It is very important that surgical treatment is carried out within 48 hours of the stroke or TIA (a mini-stroke) or before the onset of a stroke in case of high grade stenosis
Vascular surgeons have several options to remove the danger that plaque presents. Ultrasound screening for carotid stenosis is essential when any symptoms appear.
All patients should be offered a consultation about the best option available to them based on their medical history and preference.
The patient can be prescribed drug therapy for hypertension, diabetes or high cholesterol and get antiplatelet therapy avoiding clot formation at the plaque site.

Prof. Dr. H. Schumacher
Over time, plaque narrows the carotid arteries and tends to get instable at the surface, with local rupture exposing the atheroma to circulation.
Only open surgery can completely remove that plaque and is considered an aversion technique: the artery is cut out of the bifurcation, plaque is removed and the carotid bifurcation is reconstructed by reinserting the artery using a running suture to avoid graft material.
The problem is solved from inside the body using stents inside the carotid artery to widen the artery and improve blood flow. This is technically challenging but can be helpful in selected cases.
