890ASSESSMENT OF PERIPHERAL ARTERIAL DISEASE OF LOWER LIMB -TO USE OF DUPLEX COLOUR DOPPLERThe most prevalent disorder affecting the arteries in the lower limbs is peripheral arterial disease (PAD), which is characterised by stenosis and occlusions that can cause limb ischemia and cause symptoms including claudication, rest discomfort, ulceration, and perhaps amputation. The purpose of this study is to employ duplex colour Doppler to assess peripheral artery disease in the lower leg. It was an upcoming research. The investigation was conducted using a linear 5- 10 MHz probe and a curvilinear 3-5 MHz probe on a SIEMENE'S SONOLINE G - 50 Doppler machine in the Department of Radiodiognosis at the Sri Lakshmi Narayana Institute of Medical Sciences. The study took place between October 2012 and October 2013. SFA and PA were implicated in the majority of the lesions, especially on the right side. 20.6% of patients with atheromatous plaques had mild echogenecity, 37.9% had moderate echogenecity, and 41.3% had severe echogenecity. 10% of them demonstrated stenotic lesions ranging from 1 to 19%, 20% from 20 to 49%, 32% from 50 to 99%, and 38% from complete occlusions. It allows for the determination of the necessity for further examination by way of angiography and is the first investigation of choice in all cases of lower extremity arterial disease. It enables the evaluation and measurement of vascular disease. A colourdoppler examination also enables the monitoring of vascular diseasesdrpebyreddy@gmail.comResearch5122014 Colour Doppler, Stenosis, Amputation, Atheromatous plaquesThiravathuru Vittal Moha,Subhashini KanchiAssistant Professor of General Surgery, Sree Lakshmi Narayana Institute of Medical Sciences, Pondicherry (Affiliated to Bharath University, Chennai), India,Assistant Professor of General Surgery, Sree Lakshmi Narayana Institute of Medical Sciences, Pondicherry (Affiliated to Bharath University, Chennai), India
