Aims and objectives: Color Doppler Ultrasound Scan is a non-invasive and cheap tool than other Radiological Investigations for Screening, Diagnosis and follow-up of Vascular Diseases. In this study performed at Basaveshwara Teaching and General Hospital, Kalaburagi, Karnataka, we correlated the Clinical data with the findings of Color Doppler Ultrasound of the Lower Limb Arteries in Chronic Lower Limb Ischemic cases with Claudication. Patients and methods: Fifty Patients admitted under Department of General Surgery at Basaveshwara Teaching and General Hospital, Kalaburagi, between November 2017 and May 2019, with Claudication Pain of Lower Limb and associated symptom were studied. All examinations were done clinically and then compared with the Color Doppler Ultrasound using 7.5 MHz linear transducer connected to Digital Ultrasound Imaging System. Results: Fifty Patients were studied out of which 43 were male and 7 were female with a ratio of 6.14:1. The minimum age was 48 years and maximum age was 92 years. Number of patients were highest in the group of 51–65 years, i.e. 58%, with a mean age of 59.3 years. Thirty-nine patients were Smokers, which were statistically significant. Most common clinical presentation of the patients was gangrene with claudication pain (42%), Gangrene alone in 76% of the patients. The most common cause of lower limb ischaemia in our study was Atherosclerosis constituting 84% of all the etiology for the provided above age groups, followed by Thromboangiitis Obliterans. Femoro-Popliteal and below the knee arteries were commonly involved by these abnormalities while diabetes and hypertension were frequently associated clinical problems of these Patients. Conclusion: Doppler ultrasound has a high diagnostic yield in depicting abnormalities in Patients with clinical features of peripheral arterial disease.
