Abstract：Objective:To compare the two kinds of ultrasonic imaging technology,common ultrasonic and real-time contrast-enhanced ultrasound technology to the smooth general characteristic evaluation characteristic of portal vein flow preoperative liver transplantation.Method:For suspected portal vein after normal ultrasound examination level branches or trunk of 34 patients with embolization were given real-time contrast-enhanced ultrasound examination.Result:The spiral CT portal imaging,3D dynamic magnetic resonance angiography and the proof of the method such as a liver transplant confirmed,in 34 patients,there were 27 cases of portal vein thrombosis,7 cases of portal vein flow.The diagnostic confidence score of ordinary ultrasound technology and real-time contrast-enhanced ultrasound were respectively (8.32±1.89)score and (9.29±1.01)score.The sensitivity of ordinary ultrasound technology and real-time contrast-enhanced ultrasound technology were 87.9%and 81.9%respectively,the specificity were 32.8%and 100% respectively,the accuracy were 68.7% and 89.1% respectively.Identify embolus embolus and degree on the nature,real-time contrast-enhanced ultrasound technology was superior to common ultrasonic technology.Among them,for real-time contrast-enhanced ultrasound techniques could be displayed in 16 patients with portal vein thrombosis,real-time ultrasound imaging technology could be absolutely all identification.But in ordinary ultrasound could display in 17 patients with portal vein thrombosis,only 9 patients were identified.Conclusion:In the smooth operation of liver transplantation before the diagnosis of portal vein,the diagnostic level of real-time ultrasound imaging technology is obviously higher than that of ordinary ultrasonic technology,can provide more accurate and abundant preoperative diagnosis information,Real-time ultrasound imaging technology can be a good supplement ordinary ultrasonic technology,is worthy of clinical application.
