 Good evening everyone. I Dr. Alangrit is an JR3 radio diagnosis at IPGMAR representing my paper on the topic pattern of involvement of lower limb arteries in atherosclerotic disease correlation by Doppler and CT angiography. Peripheral arterial occlusive disease commonly referred to as peripheral arterial disease or peripheral vascular disease refers to the obstruction or deterioration of arteries other than those supplying the heart and within the brain. There are few studies in literature which have analyzed the vascular insufficiency distribution patterns and simultaneously correlated it clinically. The aims and objectives of this study were to diagnose and assess anatomical site and distribution of lower limb atherosclerosis, assessment of the severity of the vascular change by simultaneous use of UHG Doppler and CT angiography, and thirdly to help in treatment of atherosclerotic peripheral vascular disease and lower limb arteries. The material and methods in the present study comprised of 30 patients. Patients with lower limb claudication, wrist pain, gangrene, referred to the department of radio diagnosis from department of CTVS and other departments were screened by UHG Doppler first. If UHG screening revealed atherosclerotic changes in lower limb arteries, he was further evaluated by CT angiography. As a result, in our study 8, that is 26.7% of the patients were 30 to 40 years old, 20% that is 66, 20 of them that is 66.7% patients were 41 to 50 years old, and 2, that is 6.7% patient were 51 to 60 years old. 11 patients were female and 19 were male, 21 patients had history of DM, 15 patients had history of hypertension, and 14 patients had history of smoking. This is the result that is a distribution of age and years, and according to the various parameters that have been described here, distribution of age and years, distribution of history of hypertension, gangrene, according to history of smoking, and right-sided arterial wall thickening plaque, color change and DM. The various results have been displayed accordingly, as you can see on your screen. In our study, 25 patients had color change, 16 patients had gangrene. At right-limbs, patients had common femoral arterial wall thickening. So at right-sided arterial system, predominant distribution of wall thickening and plaque is at superficial femoral artery, popliteal artery, and anterior tibial artery. In left-limbs, 16 of them had common femoral arterial wall thickening. So overall distribution of wall thickening and plaque at BA, ADA, BT, and left-side of arterial system. And accordingly, there's bar diagram below represents that. The distribution of diffuse or focal involvement of right-sided arterial system. As you can see in the table, it has been listed here, the findings, distribution of diffuse or focal involvement of left-sided arterial system and right-sided artery. Now, in the conclusion, majority of patients were male, that is 19 out of 30, and there was a significant correlation between lower limb atherosclerotic disease and history of diabetes. Superficial femoral artery, popliteal artery, anterior tibial artery, posterior tibial artery, predominantly short atherosclerotic wall thickening and plaque disease. Calcification affects almost equally all the lower limb arteries are affected. Diffuse pattern of arterial involvement is predominant pattern in atherosclerotic disease rather than focal luminal components. These are the references which I had used. Thank you.
