经阴道彩超对未破裂未流产型输卵管妊娠与同侧妊娠黄体鉴别诊断的价值

Diagnosis Value of Transvaginal Color Doppler Imaging in Differentiation of Unruptured and Unabortive Fallopian Pregnancy and Homolateral Corpus Luteum Graviditatis

目的:经阴道彩色多普勒超声对未破裂未流产型输卵管妊娠与同侧妊娠黄体的鉴别诊断价值。方法:选择2013年1-12月本院收治的未破裂未流产型输卵管妊娠患者40例作为研究对象,使用经阴道彩色多普勒超声检查对40例未破裂未流产型输卵管妊娠与同侧妊娠黄体进行对比分析,观测比较输卵管妊娠包块及妊娠黄体的形态、血供分布、血流动力学参数。结果:未破裂未流产型输卵管妊娠表现为附件区环形回声,回声稍强或等于卵巢回声,中心多为无回声区;妊娠黄体可表现为低回声型、厚壁囊肿型、薄壁囊肿型,其中低回声型最为常见。输卵管妊娠组包块周边或内部血流呈现条状及点状患者总数多于妊娠黄体组,呈现无明显血流患者多于妊娠黄体组,呈现半环状、环状血流患者均少于妊娠黄体组,以上比较差异均有统计学意义(P<0.05)。输卵管妊娠组PSV低于妊娠黄体组,比较差异有统计学意义(P<0.05);输卵管妊娠组RI稍高于妊娠黄体组,但比较差异无统计学意义(P>0.05)。结论:经阴道彩色多普勒超声检查对未破裂未流产型输卵管妊娠与妊娠黄体的鉴别诊断具有重要的临床应用价值。

Objective：To explore the differential diagnosis value of transvaginal color Doppler imaging in differentiation of unruptured and unabortive fallopian pregnancy and homolateral corpus luteum graviditatis.Method：40 patients with unruptured and unabortive fallopian pregnancy in our hospital from January 2013 to December 2013 were selected as the research objects.Their unruptured and unabortive fallopian pregnancy and homolateral corpus luteum were compared and analyzed by color Doppler flow imaging.The configuration,blood supply distribution and hemodynamic parameters of the fallopian pregnancy masses and corpus luteum graviditatis were observed and compared.Result：Unruptured and unabortive fallopian pregnancy was characterized by ring echo of attachment area,the echo was equal to or slightly stronger than ovarian echo and the center was always anechoic area.Corpus luteum graviditatis performed as the types of low echo,thick wall cyst or thin-walled cyst,the low echo type was the most common.In the fallopian pregnancy group,the total number of patients with strips and dot blood in peripheral or internal of the masses and the number of patients with no obvious blood flow were higher than those in the corpus luteum graviditatis group,the numbers of patients with half circular and annular flow were all lower than those of the corpus luteum graviditatis group,the differences were all statistically significant（P〈0.05）.The PSV of the fallopian pregnancy group was lower than that of the corpus luteum graviditatis group,the difference was statistically significant（P〈0.05）,the RI of the fallopian pregnancy group was slightly higher than that of the corpus luteum graviditatis group,the difference was not statistically significant（P〈0.05）.Conclusion：The transvaginal color Doppler ultrasound has important clinical application value in the differential diagnosis of unruptured and unabortive fallopian pregnancy and corpus luteum raviditatis.
