Résumé
Objective To explore the value of contrast-enhanced ultrasonography (CEUS) in diagnosis of esophagogastric varices (EGV) compared with color Doppler flow imaging (CDFI). Methods CDFI and CEUS were performed on 23 variceal patients based on the B mode ultrasound examination. The blood flow of esophageal varices (EV) or gastric varices (GV) displayed with CDFI and CEUS were compared. Results The flow signal demonstration rate of EV with CDFI and CEUS was 42.11% (8/19) and 73.68% (14/19), while that of GV with CDFI and CEUS was 76.47% (13/17) and 94.12% (16/17), respectively. CEUS displayed the flow signal of EV better than CDFI did (χ~2=4.17, P＜0.05), but the flow signal demonstration rate of GV was not significantly different (χ~2=1.33, P＞0.05). Conclusion CEUS can be used more extensively in clinic practice for diagnosis of EGV.
