[Asymptomatic stenoses and thromboses of the carotid arteries: hemodynamic and ultrasound aspects].

The problem of asymptomatic stenoses of the internal carotid artery (ICA) has become a matter of great concern especially after ultrasonography of the great arteries of the head and, first of all, duplex scanning were introduced on a wide-scale basis into practice of the physicians of varying specialties. The growing population of patients with asymptomatic stenoses raises the problem of their further management with the purpose of preventing ischemic stroke. In connection with significant advances in vascular surgery carotid endarterectomy (CEE) has assumed an increasing role in the treatment of carotid stenoses.
