[Prediction of ischaemic lesions of the brain in reconstructive operations on internal carotid arteries].

The present study was undertaken to examine the relationship between the level of the intensity of the ultrasonic signal reflected from atherosclerotic plaques (ATP) of carotid arteries and the risk for formation of an ischaemic lesion in the brain matter, detected during diffusion-weighted magnetic resonance imaging (DW-MRI) performed 24 hours after carotid endarterectomy (CEA) or carotid angioplasty and stenting (CAS). Our prospective study included a total of 78 patients presenting with stenosis of the sinus of the interior carotid artery. Of these, 42 patients were subjected to CEA and 36 subjects endured CAS.
