[Diagnosis and prognosis of carotid artery stenosis].
The diagnosis of a carotid stenosis inevitably includes a neurological examination as well as CCT or MRI of the brain. Typical neurological and neuropsychological symptoms and signs as well as syndromes are described according to the vascular supply areas of the brain. CCT as well as MRI may identify cerebral infarction or other diseases and additionally give some information with regard to the underlying etiology or pathogenesis of an infarct. Satisfactory non-invasive demonstration of the carotid and vertebral arteries including their intracranial branches can be achieved by the use of sonographic methods (Dopplersonography, B-mode imaging, Duplex and colour-coded systems). Additionally, transcranial Dopplersonography is mandatory in most instances. Cerebral angiography is only justified preoperatively or for a disease which cannot be diagnosed reliably by other means, eg. cerebral venous thrombosis. The prognosis of a carotid stenosis depends not only on the degree of luminal narrowing and the shape of the stenosis but also on the clinical status of the patient (asymptomatic or symptomatic carotid stenosis, accompanying coronary artery disease etc.). Prophylactic treatment implies therapy of risk factors as well as antiaggregation, anticoagulation and carotid endarterectomy in selected cases.
