In asymptomatic patients with chronic carotid occlusion, the cause of the occlusion needs to be identified and risk factors such as hypertension, hyperlipidemia, hyperglycaemia, hyperhomocysteinemia, smoking and obesity need to be controlled.
Perform haemodynamic investigations such as PET, CT perfusion imaging and MR perfusion imaging. If haemodynamic compromise is present, surgical management may be considered in addition to medical treatment.
