ABSTRACT

Objective To explore the value of high frequency and color doppler ultrasonography on diagnosis of deep venous thrombus in lower extremitiy.Method 32 cases with lower extremitiy deep venous thrombi diagnosed by angiography were further examined by CDFI,36 healthy cases were randomly selected as the normal group (NOR).Results High frequency and CDFI displayed the venous image in normal lower limbs rapidly and clearly as well as the echographic features of different shapes and types of the obstructed vessels.Conclusion High frequency and CDFI as a non-invasive and realtime method is better than angiography in diagnosis of the disease.
