目的：探讨宫内早孕与异位妊娠子宫内膜变化的声像图特征。方法107例患者分为宫内早孕组51例和异位妊娠组56例，经腹超声观察其子宫内膜回声特征和血流频谱性质，测量子宫内膜厚度、动脉舒张期最低血流速度（Vmin）及阻力指数（RI），直至子宫宫腔内或宫腔外部位出现妊娠囊，计算子宫内膜增长速度，结果进行对比分析。结果宫内早孕组和异位妊娠组子宫内膜增长速度分别为（0．52±0．14） mm/d和（0．15±0．15） mm/d；子宫内膜厚度分别为（16．29±2．21） mm和（9．14±2．48） mm，差异有统计学意义（U＝12．76、15．89，均P＜0．01）；以子宫内膜增长速度﹤0．4 mm/d为诊断异位妊娠的分界点，其敏感性为85．7％，特异性为82．4％。异位妊娠组子宫内膜呈线状强回声48例，呈磨玻璃样改变8例，宫内早孕组51例均呈磨玻璃样改变，差异有统计学意义（χ2＝62．34，P＜0．01）；宫内早孕组检出2例子宫内膜周边滋养动脉，异位妊娠组无一例检出子宫内膜滋养动脉，差异无统计学意义（χ2＝2．21）。结论超声检测子宫内膜增长速度、子宫内膜厚度及回声特征，有利于宫内早孕和异位妊娠之间的鉴别诊断。
目的：探討宮內早孕與異位妊娠子宮內膜變化的聲像圖特徵。方法107例患者分為宮內早孕組51例和異位妊娠組56例，經腹超聲觀察其子宮內膜迴聲特徵和血流頻譜性質，測量子宮內膜厚度、動脈舒張期最低血流速度（Vmin）及阻力指數（RI），直至子宮宮腔內或宮腔外部位齣現妊娠囊，計算子宮內膜增長速度，結果進行對比分析。結果宮內早孕組和異位妊娠組子宮內膜增長速度分彆為（0．52±0．14） mm/d和（0．15±0．15） mm/d；子宮內膜厚度分彆為（16．29±2．21） mm和（9．14±2．48） mm，差異有統計學意義（U＝12．76、15．89，均P＜0．01）；以子宮內膜增長速度﹤0．4 mm/d為診斷異位妊娠的分界點，其敏感性為85．7％，特異性為82．4％。異位妊娠組子宮內膜呈線狀彊迴聲48例，呈磨玻璃樣改變8例，宮內早孕組51例均呈磨玻璃樣改變，差異有統計學意義（χ2＝62．34，P＜0．01）；宮內早孕組檢齣2例子宮內膜週邊滋養動脈，異位妊娠組無一例檢齣子宮內膜滋養動脈，差異無統計學意義（χ2＝2．21）。結論超聲檢測子宮內膜增長速度、子宮內膜厚度及迴聲特徵，有利于宮內早孕和異位妊娠之間的鑒彆診斷。

Objective To investigate the early intrauterine pregnancy and ectopic pregnancy endometrial sonographic characteristics. Methods Totally 107 patients were selected with pregnancy but without a clear location of clinical were divided into early intrauterine pregnancy group(51 cases) and ectopic pregnancy group(56 cases). Each case was follow-up observed by abdominal color Doppler ultrasound on the endometrial echo features,the endometrial thickness and the nature of endometrial blood flow spectrum[(the artery minimum diastolic velocity(Vmin) and resistance index(RI)] were measured until the gestational sac appeared in uterine cavity or outside parts of it. The endometrial growth rate was calculated. The results were comparatively analyzed. Results Endometrial growth rates and endometrial thickness of early intrauterine pregnancy group and ectopic pregnancy group were (0.52±0.14) mm/d,(0.15±0.15)mm/d and (16.29±2.21) mm,(9.14±2.48)mm with statistical significance between the two groups(U=12.76,15.89,P<0.01). Endometrial thickening rate less than 0.4 mm/d was chosen as the cutoff point for the diagnosis of ectopic pregnancy, with a sensitivity of 85.7%and a specificity of 82.4%. Endometrial showed linear strong echo in 48 cases in ectopic pregnancy group and ground-glass change was found in 8 cases. Endometrial showed ground-glass change in all 51 cases in early intrauterine pregnancy. Statistical significance was found between the two groups (χ2=62.34,P<0.01).Endometrial nutrient artery was detected in 2 cases in early intrauterine pregnancy goup but not in ectopic pregnancy group. No statistical significance was found between the two group (χ2=2.21). Conclusion Detection of endometrial growth rate, thickness and echo features by ultrasonography can help to identify the early intrauterine pregnancy with the ectopic pregnancy.
