ABSTRACT

Introduction. Using high-resolution ultrasound techniques has proven to be a valid method for the study of extracoronary atherosclerosis, and has been used extensively in the study of carotid and intracranial atheromatous disease. Objective. To determine the presence and sonographic characterization of carotid atheromatous plaques in patients with a diagnosis of cerebral vascular disease ischemic type. Material and methods. An observational, transversal, descriptive and analytical data included patients admitted to the Emergency Department and Internal Medicine with cerebral vascular disease ischemic type in Hospital Regional “General Ignacio Zaragoza”, ISSSTE. A total of 60 patients both sexes and all age groups included in the study protocol, 23 female and 37 male. We used a Phillips HD equipment EnVisor hp 2008, b mode, color Doppler and spectral Doppler angiography, 5-12 MHz linear transducer and 2-5MHz convex. Results. Of a total of 60 patients with sonographic data of atherosclerotic plaques, 44% females and 56% male, both showed heterogeneous plaques, 44% women and 56% men with plates homogeneous, the degree of stenosis was, without plates 8% men and 13% women, stenosis less than 50% with 89% men and 87% women and occlusion 3% male. Discussion. The high-resolution ultrasound has emerged as a reliable and effective method for the detection of atherosclerotic carotid lesions in a simple, noninvasive and low cost, and provides information about the presence and extent. Conclusion. Ultrasound is a tool that can assess the extent, morphology and degree of stenosis of the same and thus to prevent the onset of ischemic cerebrovascular disease in patients who have clinical suspicion of being candidates to develop it.
