摘要
目的:探讨超声造影鉴别良、恶性门静脉栓子的价值。材料和方法:回顾性分析14例经穿刺活检病理证实的肝细胞性肝癌合并门静脉瘤栓(其中1例合并血栓)和3例经CT、实验室检查及抗凝治疗证实的门静脉血栓患者的超声造影表现。结果:13例门静脉瘤栓患者,超声造影动脉期见瘤栓呈线条状或点状快速增强,门静脉期管腔呈充盈性缺损。1例瘤栓合并血栓形成患者,动脉期栓子部分快速增强,部分始终未见增强,门静脉期管腔呈充盈性缺损。3例门静脉血栓患者,动脉期未见栓子增强,门静脉期管腔呈充盈性缺损。结论:超声造影有助于良、恶性门静脉栓子的鉴别诊断。
Purpose：Portal vein thrombi could be induced by malignant or benign causes.The aim of this study was to evaluate the feasibility and efficacy of contrast-enhanced ultrasonography in the differentiation of benign from malignant thrombus in the portal vein.Materials and Methods：Contrast-enhanced ultrasound in 17 cases with portal vein thrombi was retrospectively analyzed.Results：On the contrast-enhanced ultrasound,the malignant thrombi in 13 cases were enhanced rapidly in arterial phase in a linear or dot shape,and filling defect noted in the portal phase.Partial enhancement in arterial phase and defect in portal phase were noted in one case combining benign and malignant thrombus.No enhancement in arterial phase or portal phase filling defect was noted in 3 cases of benign thrombi.Conclusion：Contrast-enhanced ultrasound could be used to differentiate the malignant thrombi from benign ones.
