Objective To investigate the value of transvaginal ultrasound in the differential diagnosis of corpus luteum and unruptured ectopic pregnancy. Methods 35 cases of pregnancy corpus luteum cyst patients and 40 patients with unruptured ectopic pregnancy transvaginal color Doppler sonography in obstetrics and gynecology were chosen.The corpus luteum cyst size and blood flow in patients with luteal spectrum were observed,and adnexal mass size and flow spectrum in patients with unruptured ectopic pregnancy were observed. Results Corpus luteum cyst routine sonogram showed hypoechoic,thick-walled cyst type,thin-walled cyst internal echo pattern and thin-walled cyst type. Unruptured ectopic pregnancy showed a mass of different sizes.Corpus luteum cyst patient's bloodstream,mostly semi-circular and annular flow signals,both from within the ovary;without rupture of blood flow in patients with ectopic pregnancy are much more blood spots and stripes,are not derived from the ovary,the two groups there were significant differences (P < 0.05).Corpus luteum cysts more performance for low resistance and high resistance to flow spectrum;patients with unruptured ectopic pregnancy is manifested in various types of flow spectrum,there are significant differences between the two groups (P < 0.05).Corpus luteum cysts of PI and RI were lower in patients with unruptured ectopic,the difference was statistically significant (t=-3.531,-4.262,P < 0.05). Conclusion Transvaginal ultrasound can identify and diagnose pregnancy corpus luteum cyst with unruptured ectopic pregnancy.It is worthy for clinical application.%目的：探讨经阴道超声对妊娠黄体囊肿与宫外孕未破裂型的诊断价值。方法选取我院妇产科35例妊娠黄体囊肿患者和40例宫外孕未破裂型患者行阴道彩色多普勒超声检查，观察妊娠黄体囊肿患者黄体大小及血流频谱，观察宫外孕未破裂型患者附件包块的大小及血流频谱。结果妊娠黄体囊肿常规声像图表现为：低回声型，厚壁囊肿型，薄壁囊肿内部回声型，薄壁囊肿型；宫外孕未破裂型表现为大小不一的包块。妊娠黄体囊肿患者血流多为半环状和环状血流信号，均来自卵巢内；而未破裂型宫外孕患者血流则多为点状和条状血流，均不来源于卵巢，两组比较有统计学差异（P ＜0.05）。妊娠黄体囊肿患者多表现为低阻力和高阻力血流频谱；宫外孕未破裂型患者则表现为各型血流频谱，两组比较有统计学差异（P ＜0.05）。妊娠黄体囊肿患者的 PI 和 RI 均低于宫外未破裂型患者，差异具有统计学意义（t=-3.531，-4.262，P ＜0.05）。结论经阴道超声检查能够鉴别和诊断妊娠黄体囊肿与宫外孕未破裂型，值得推广应用于临床。
