  • Title: Colour flow mapping in the diagnosis of the calf deep vein thrombosis.
    Author: Bradley MJ, Spencer PA, Alexander L, Milner GR.
    Journal: Clin Radiol; 1993 Jun; 47(6):399-402. PubMed ID: 8519146.
    Abstract:
    This prospective trial was organized to evaluate further the role of colour flow Doppler ultrasound techniques in the diagnosis of deep vein thrombosis (DVT) with particular reference to the isolated calf lesion. In 100 patients ultrasound was compared against the recognized gold standard of ascending venography. Fifty venograms were positive for DVT compared with 49 on ultrasound, a sensitivity of 98%. The specificity of ultrasound for DVT in the 50 patients without DVT on venography was 100%. Forty-five venograms demonstrated calf thrombus with varying proximal extent. Sixteen proved to be isolated calf lesions and these were all identified by ultrasound (100% sensitivity and specificity respectively for isolated calf DVT). In five of these isolated calf thrombus cases, results suggested that ultrasound better diagnosed the presence of thrombus. Ultrasound diagnosed significant pathology in 13 of the normal venogram patients giving an overall diagnostic yield of 62% as compared to 50% at venography.
