[Neurology and carotid artery interventions. What has to be done first?].

Optimum therapy for patients with carotid stenosis requires the interdisciplinary cooperation of surgeons, neurologists and angiologists. Important diagnostic methods are ultrasound sonography, contrast-enhanced computed tomography, magnetic resonance tomography and digital subtraction angiography. Treatment of carotid artery stenosis depends on whether the stenosis is symptomatic or asymptomatic. The treatment of choice (medical therapy only vs. carotid artery stenting vs. carotid endarterectomy) depends on the characteristics of the stenosis, the presence of cerebral lesions and the general physical condition of the patient. After the intervention continuous monitoring and treatment of vascular risk factors are mandatory.
