Type of Research Project
- Clinical Project without Laboratory work
What is the background of the project?
This project is proposed to screen for peripheral artery occlusive disease in hospitalized patients: patients suffering from coronary syndrome in Cardiology department, patients suffering from diabetes in Endocrinology department and patients suffering from chronic kidney disease in Nephrology department by measurement of Ankle-brachial pressure index. Peripheral artery occlusive disease is a narrowing of the arteries other than those that supply the heart or the brain,that most commonly affects the legs, but other arteries may also be involved. More than 30% of the patients hspitalized in the vascular surgery department are suffering from peripheral artery occlusive disease. What is the aim of the project? To know the prevalence of arterial occlusive disease of lower limbs for hospitalized patients in Cardiology, Nephrology and Endocrinology departments What techniques and methods will be used? Measure of the Ankle-brachial pressure index : The ankle-brachial pressure index (ABPI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm. The patient must be placed supine, without the head or any extremities dangling over the edge of the table. Measurement of ankle blood pressures in a seated position will grossly overestimate the ABI A Doppler ultrasound blood flow detector and a sphygmomanometer are usually needed (Provided by the department). The blood pressure cuff is inflated proximal to the artery in question. Measured by the Doppler wand, the inflation continues until the pulse in the artery ceases. The blood pressure cuff is then slowly deflated. When the artery's pulse is re-detected through the Doppler probe the pressure in the cuff at that moment indicates the systolic pressure of that artery. The higher systolic reading of the left and right arm brachial artery is generally used in the assessment. The pressures in each foot's posterior tibial artery and dorsalis pedis artery are measured with the higher of the two values used as the ABI for that leg
What is the aim of the project?
The aime of the project is to know the means of deep screening for occlusive disease of the peripheral artery. And by the end of the project, the student should be able to : 1/ know the risk factors of the occlusive disease of the peripheral artery 2 / to know how to make a vascular Doppler ultrasound 3 / and to know how to diagnose the disease
What techniques and methods are used?
- Vascular Doppler ultrasound - Maneuvers of measurement of the tibio-brachial index - Calculate the tibio-brachial index
What is the role of the student?
- The student will observe the practical experiments but will be highly involved in the analysis of the results
What are the tasks expected to be accomplished by the student?
1/follow the evolution of the tibio-brachial index of hospitalized patients in cardiology nephrology and endocrinology 2/ Treat their files
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a poster - The student will prepare a presentation
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
Student in clinical years knowing the definition and stages of the arterial occlusive disease of lower limbs and how to measure the Ankle-brachial pressure index (the students will be thought how to measure at their arrival)
Are there any legal limitations in the student’s involvement
