［摘要］目的：探讨经阴道彩色多普勒对诊断无症状宫外孕的临床价值。方法：回顾性分析106例经临床确诊的无症状宫外孕患者的声像图的特征性表现。并选取62例宫内早孕为对照组，观察宫外孕及宫内早孕子宫内膜的变化，并检测孕囊周边、附件区包块内有无滋养动脉血流。结果：106例宫外孕组中85例(80.2%)可清晰显示附件区的输卵管环征，82例(77.4％)子宫内膜呈现与正常月经周期增生晚期子宫内膜改变相似的“三线样”声像图改变，81例(占76．4％)于附件区包块检测到滋养动脉血流信号；62例宫内孕组子宫内膜均于“三线样”改变，51例(82．3%)于孕囊周边检测到滋养动脉血流信号。结论：经阴道彩色多普勒对无症状宫外孕的诊断有较大的临床应用价值。 (本免费论文文来自http://wwww.coollw.com)

　　Abstract:Objective To explore the clinical value of,transvaginal coler doppler sonographyin diagnosing asymptomatic ectopic pregnancy．Methods Transvagmal color doppler sonography was performed in 106 patients with asymptomatic ectopic pregnancy and the sonographic features analysed．62 women of early intrauterine pregnancy were chosen for control,endomertnum of the women of early intrauterine and ecto pic pregnancy were observed bytransvaginal color doppler sonography，and trophoblastic artery flow were investigated surrounding the intrauterine embryo or in the conglomeration of salpinx．Results In the group of 106 cases of ectopic pregnancy,the tubal ring could be demonstrated clearlyin 85 cases(80．2%)．An endometrial threeline pattem resembled late proliferative endometrium of the normal menstrual eyele were seen in 82(77．4%) ectopic pregnancy．81(76．4%)ectopic pregnancy had trophoblastic artery flow wythin the conglomeration of salpinx．An endometrial threeline pattern were not seen in 62 early intmuterine pregnancy,51(82.3％)early intrauterine pregnancy had tropho blastic artery flow suttounding the intrauterine embryo．Conclusion Transvaginal color dopper sonography is an important diagnostic modality in diagnosing asymptomatic ectopic pregnancy．

　　1．1 临床资料选取168例患者，年龄19岁~45岁，平均24岁，均有停经史31 d~68 d，平均41 d，尿HCG阳性而无任何症状或仅有少量阴道流血，于2003年6月至2005年6月在我院就诊。其中106例为经内膜诊刮临床检查或外科手术证实为宫外孕，62例为宫内孕，无宫内宫外同时妊娠。

　　1．2 仪器与方法采用LOGIO5彩色多普勒超声诊断仪，经阴道探头，探头频率5．0 MHz~7．5 MHz，患者排空膀胱，阴道探头套上避孕套，缓慢进入阴道，重点观察附件区包块大小、回声、边界，其内有无孕囊、胚芽、胎心搏动，包块与同侧卵巢关系，盆腔积液的范围深度，宫内有无孕囊、胚芽及胎心搏动，子宫内膜厚度与层次，观察附件区包块及子宫内孕囊血流信号，测量Vmax、Vmin及RI。

106例宫外孕患者中32例初次经阴道彩色多普勒检查于宫外未见异常回声，分别于初次检查的3 d~8 d复查而显示附件区包块。宫外孕组均可见子宫增大或正常大小，宫腔内均未见孕囊回声，106例宫外孕中82例(77．4%)子宫内膜呈现与正常月经周期中增生晚期子宫内膜改变相似的“三线样”声像图，35例(33．0％)可见宫腔内少许液性暗区或假孕囊。
