SummaryPatients undergoing orthopedic surgery are at high risk of developing deep vein thrombosis. One hundred and thirty-eight consecutive patients undergoing total hip replacement or hip fracture surgery were included in this study. They were surveilled with colour Doppler ultrasound (CDU) and bilateral ascending contrast phlebography. The prevalence of proximal and distal DVT in this study was 5.8% and 20.3% respectively.CDU has a satisfactory sensitivity in patients with symptomatic deep vein thrombosis, especially in the proximal region. These results could not be confirmed in the present study of asymptomatic patients. The sensitivity was 62.5% (95% confidence interval: C.I. 24-91%) and the specificity 99.6% (C.I. 98-100%) for proximal DVT; 53.6% (C.I. 34-73%) and 98% (C.I. 96-99%) respectively for distal thrombi. The overall sensitivity was 58.1% (C.I. 39-75%) and the specificity 98% (C.I. 96-99%). The positive predictive value was 83.3% (C.I. 36-99%) and 75% (C.I. 51-91%) for proximal and distal DVT respectively. The negative predictive value was 98.9% (C.I. 98-100%) and 94.9% (C.I. 92-98%) for proximal and distal DVT respectively. The results of this study showed that even with a highly specialised and experienced investigator the sensitivity of CDU was too low to make it suitable for screening purposes in a high risk surgical population.

Background: Venous abnormalities of lower limb are a fairly common cause of morbidity. Although clinical diagnosis is the cornerstone of the diagnosis of lower limb venous disease, Colour Doppler ultrasound has become the investigation of choice to confirm the diagnosis. This study evaluated the role of Colour Doppler ultrasound in various venous pathologies of the lower limb and the sonographic findings were correlated with surgical and clinical findings.Methods: 100 patients of all age groups of either sex presenting with clinically suspected entities affecting venous system of the lower limb were selected for this study.Results: Our study showed a definite male preponderance (65%) with an incidence of 41% in the age group of 21-40 years. Isolated varicose veins had an incidence of 58% followed by isolated deep vein thrombosis (DVT) (29%), varicose veins with thrombophlebitis (5%), DVT with thrombophlebitis (5%), DVT with varicose veins (2%) and hematoma (1%). The findings correlated with surgery and gave a sensitivity of 100%.Conclusions: Colour Doppler ultrasound is unique due to its feasibility, accessibility and cost effectiveness. Its dynamism is also exploited by various maneuvers done by the patients, radiologist and the machine parameters to bring about changes in blood flow to reach the exact diagnosis.
