摘　　要：目的 探讨经阴道能量多普勒血流显像（PDI）对恶性滋养细胞肿瘤的诊断价值。方法 对43例经病理诊断为恶性滋养细胞肿瘤的PDI血流显像特征进行回顾性分析,通过比较正常组、良性和恶性肿瘤子宫肌层内血流能量图的差异,探讨声像特点与不同肿瘤的关系;结合血清绒毛膜促性腺激素（β-hCG）观察治疗前后子宫壁肌层血流变化。结果 正常组肌层子宫血流特点：肌层内散在分布的星点状血流信号,血管形态规则;良性组血流特点：呈短杆状,形态较规则;恶性肿瘤血流特点：呈火海征,肌层极为丰富,形态不规则;治疗前后随着β-hCG的降低,宫壁血流的长度与宽度有明显缩小。结论 PDI对恶性滋养细胞肿瘤有明确的诊断价值,PDI对化疗的观察及了解患者预后有指导意义。Objective To evaluate the diagnostic value of power Doppler ultrasonography through vagina in malignant trophoblastic tumor（MTT）.Methods The features of power Doppler flow imaging of 43 cases with MTT were studied retrospectively.The imaging differences in normal group,benign gestational trophoblastic tumors and malignant gestational tropho-blastic tumors were compared,and the relationship between imaging character and benign or malignant gestational trophoblastic tumors was analyzed.At the same time,the change of blood flow in uterine intramuscular layer was obeserved before and after chemotherapy combined with β-hCG.Results The blood folw character of uterine intramuscular layer in normal group was punctate and scattered blood flow signal,flow shape was regular;The blood folw character of uterine intramuscular layer in benign gestational trophoblastic tumors group was short pole blood flow signal,flow shape was less regular;The blood folw character of uterine intramuscular layer in malignant gestational trophoblastic tumors group was very rich blood flow signal,flow shape was anomalistic;After chemotherapy,the extent and diameter of the blood folw of uterine intramuscular layer was decreased seriously,while the β-hCG reduced.Conclusion PDI had diagnostic value in MTT and could be seemed as a guide for observing the chemotherapeutic effect and prognosis of MTT.
