摘　　要：目的探讨提高门静脉异常回声的超声诊断准确性。方法对常规超声检查发现的30例门静脉异常回声进行超声微泡造影。6例经穿刺活检或手术病理检查证实,24例结合临床资料及增强CT或MR检查证实。结果 27例癌栓动脉相21例癌栓呈整体性高增强,6例癌栓部分高增强,部分充盈缺损;门脉相呈等或低增强,延迟相呈低增强。3例血栓造影过程中,2例无增强,1例门脉相节段性增强。结论超声造影能准确鉴别癌栓与血栓,为进一步明确病变的检出、性质、分期、治疗及预后提供参考价值。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 .
