Abstract: Objective To improve the accurate ultrasonography of the portal vein abnormal echoes .Methods 30 cases of portal vein abnormal echo with conventional ultrasound examination were contrast-enhanced by ultrasound microbubble .6 cases were con-firmed by biopsy or surgical pathology ,24 cases were confirmed after clinical data and enhanced CT or MR .Results 27 cases of tumor thrombus in the arterial phase ,of which 21 cases were overall uniformity enhanced ,6 cases was part of the high enhance-ment ,partial filling defect ;In portal venous phase all was equal or lower enhancement ;in delayed phase all showed low enhance-ment .3 cases of thrombosis were contrast-enhanced process with 2 cases without enhancement ,1 case of portal vein segmental en-hancement .Conclusion Contrast-enhanced ultrasound microbubble can accurately identify tumor thrombus and thrombosis ,and provid the reference value to further clear of the disease detected in nature ,staging ,treatment and prognosis .
