COMPARATIVE COLOUR DOPPLER STUDY OF LOWER LIMB DEEP VENOUS THROMBOSIS IN DIABETIC AND NON DIABETIC PATIENTS WITH REVIEW OF CURRENT KNOWLEDGE

INTRODUCTION: The present study was aimed at comparing the clinical characteristics of DVT patients with and without DM. The risk of venous thromboembolism appears to be elevated in both type 1 and type 2 diabetic patients. Hyperinsulinemia, which is often present in type 2 diabetes has been shown to have a prothrombotic effect as well. Doppler ultrasonography serves as reliable, non-invasive and rapid investigation to detect DVT. Therefore helping in the early detection of DVT in clinically suspected patients. On USG, findings in favour of DVT are non-compressible venous segment with loss of phasic flow on Valsalva, shows absent colour flow if completely occlusive and lack of flow augmentation with calf squeeze and increased flow in superficial veins. OBJECTIVES: To assess and analyze the colour Doppler findings and to evaluate the site, extent and stage of lower limb deep vein thrombosis in diabetic as well as non-diabetic patients. METHODS: Present observational comparative study was conducted in the Department of Radio-diagnosis of tertiary level care. CONCLUSION: Incidence of deep vein thrombosis in diabetic and non-diabetic patients differs, however it is not statistically significant. Anatomic localization of the thrombus revealed that common iliac, external iliac, common femoral, femoral and popliteal vein involvement was more common among diabetics as compared to non-diabetics. RESULTS: Total 36 patients were enrolled in this study of this 21 were diabetic and 15 were non-diabetic. The incidence of DVT was found to be 21% among diabetics and 15% among non-diabetics.
