Abstract :

Introduction: Deep vein thrombosis (DVT) and its sequel, pulmonary embolism, is a significant clinical problem. Ultrasound is primary, non invasive, cheap, easily available modality for localization and characterization of the thrombus. Aim: To evaluate the role of Color Doppler ultrasound as an imaging modality in diagnosing DVT of lower limbs. Methods: This prospective observational study was conducted on 50 patients with clinically suspected DVT of lower extremities, referred for Color venous Doppler ultrasound imaging. In the patients with positive findings, venous segment involved and the appearance of thrombus was noted. Results: Out of 50 clinically suspected patients, out of 38 patients positive for DVT, >50% were of > 40 years of age with male predominance (55%). Main risk factors for DVT were post surgery (30%), post trauma (22%) and hypercoagulable state (pregnancy, OCPs) (16%). Thrombus was seen in 10% of external iliac vein, 22% of common femoral vein, 26% of superficial femoral veins, 23% of popliteal vein and 19% of tibial venous segments. In this study, the percentage of acute, subacute and chronic DVT was 8%, 86.8%, 5.2%. Out of these,14% of veins showed partial occlusion and 86% showed complete occlusion of venous segments. Conclusion: Color venous Doppler ultrasound was useful in diagnosing DVT in clinically suspected patients. In this study, Superficial femoral vein and Popliteal veins were most commonly involved. Subacute thrombus was most common type of thrombus found.
