Carotid artery stenosis

Preventing strokes with early prevention

A stroke means a fundamental life change to those who are affected. Could it have been avoided? In a certain way, yes it can be. An early ultrasound examination, appropriate diagnosis and the right treatment help to prevent the worst.

Our vascular surgeons at Schoen Clinic have decades of experience in the treatment of carotid artery stenosis. Due to this expertise, they make the right decision for you and with you.

Causes & symptoms

Causes: How carotid artery stenosis comes about

In about 20 per cent of cases, the cause of a stroke is a more narrowed carotid artery. The most frequent cause of this constriction is the increasing calcification of vessels from atherosclerosis. 

Symptoms: Initially no discomfort

A constriction of the carotid artery (carotid artery stenosis) does not cause any localised pain. However, after a constriction of about 70 percent, the risk of having a stroke increases significantly due to an embolism in the cerebral arteries. The narrower the carotid artery stenosis, the higher the risk. This risk of a stroke can be reduced by a timely diagnosis and corresponding medication and surgical treatment, if necessary.

Diagnostics

Diagnosis: How we determine carotid artery stenosis

We recommend men and women in their late forties and on to have their carotid arteries examined via special ultrasound (duplex sonography).

Our vascular surgery department offers you regular vascular consultations where we can check your carotid arteries among other things. Afterwards you will receive an extensive consultation from our specialists.

Using the colour-coded Doppler ultrasound imaging, we combine ultrasound images of the tissue with a coloured representation of the blood flow, detecting flow turbulences and accelerations. We then measure the flow speed of your blood in the arteries supplying the brain, thereby determining the degree of any existing restriction.
