Abstract
We observed lower extremity blood flow in deep venous thrombosis (DVT) patients using ultrasonography after orthopaedic hip joint operation. Between July 1999 and June 2000, four patients underwent total hip arthoplasty and hemi-surface arthroplasty was performed on one. We measured the flow volume of the femoral vein and the great saphenous vein using ultrasonography on all patients after venography. The patients consisted of one male and four females with a mean age of 67 years (age range: 47 to 74 years). Deep venous thrombosis was identified in two (40 percent) of the five patients. There was no significant difference in the flow volume of the femoral vein between the DVT (+) group and DVT (-) groups (129±33ml/m, 165±89ml/m). The flow volume of the great saphenous vein in the DVT (+) group increased significantly (189±108ml/m, 51±22ml/m p<0.01). Since measurement of the flow volume of the great saphenous vein was comparatively easy using ultrasonography, we concluded that it is useful for DVT screening.
