Resumen
Actualmente la cifra de muertes por ECV supera los 5 millones anuales, lo que equivale a 1 de cada 10 muertes, la prevalencia de estenosis carotidea extracraneal de cualquier grado se incrementa con la edad y pasa de un 8% en la década de los 40 a un 40% en la de los 50 llegando a ser una lesión muy frecuente a los 70 años (80%), las patologías Carotideas pueden provocar estenosis, producidas por placas en el interior de la pared de las arterias, hay un riesgo alto de que la arteria sea obstruida por coágulos de sangre o que fragmentos de placa de ateroma embolicen en el cerebro provocando un ACV, al prevenir eventos cerebrovasculares que son ocasionados por patologías carótideas, mediante la valoración del flujo arterial, por medio del ecodoppler, los hallazgos del eco carotideo nos permitirán observar cómo pueden estar otros lechos vasculares y así conocer y diferenciar los problemas que ocasionan las patologías de las arterias carótidas y sus prevenciones, el presente trabajo se enfoca en expresar de mejor forma la utilización de las técnicas ecograficas para usos diagnósticos, suponen una alternativa eficaz e inocua para la evaluación de procesos orgánicos determinados, que nos permitan definir algunos criterios para la evaluación no invasiva por eco-Döppler de las lesiones arteriales, la metodología utilizada estuvo dada por el apoyo bibliográfico, documental, electrónico y con la investigación explicativa, descriptiva y experimental, se utilizó la técnica de la encuesta cuyo instrumento fue un cuestionario Likert, juicio de expertos y control por el director y tutor.
Currently the number of deaths due to CVD exceeds 5 million per year, equivalent to 1 in 10 deaths, the prevalence of extracranial carotid stenosis of any degree increases with age and goes from 8% in the 40s to 40% in the 50's becoming a very common injury at 70 years (80%), Carotid pathologies can cause stenosis, produced by plaques inside the wall of the arteries, there is a high risk that the artery is obstructed by blood clots or fragments of atherosclerotic plaque embolize the brain causing a stroke, by preventing cerebrovascular events that are caused by carotid pathologies, by evaluating the arterial flow, by means of the ecodoppler, the echo findings carotid will allow us to observe how other vascular beds can be and thus know and differentiate the problems caused by pathologies of the carotid arteries and their prevention, the present t This work focuses on better expressing the use of ultrasound techniques for diagnostic purposes, they represent an effective and safe alternative for the evaluation of determined organic processes, which allow us to define some criteria for the non-invasive evaluation by eco-Döppler of the lesions. arterial, the methodology used was given by bibliographic, documentary, electronic support and with explanatory, descriptive and experimental research, the survey technique was used whose instrument was a Likert questionnaire, expert judgment and control by the director and tutor.
