目的探讨经腹和经阴道彩色多普勒超声对子宫瘢痕处早期妊娠诊断中的诊断价值。方法回顾性分析总结30例经确诊为子宫瘢痕处早期妊娠患者的经腹及经阴道彩超检查声像图。结果经腹彩超检查诊断符合率为66.67%;经阴道彩超检查诊断符合率为93.33%,经阴道彩超诊断符合率显著高于经腹彩超诊断符合率,差异有统计学意义(P<0.05)。其中30例子宫瘢痕处妊娠的患者中,有19例为孕囊型、9例不均质包快型、2例混合型,其区别主要表现在子宫前壁的下段的表现,及周围血流信号的不同。结论与经腹壁超声相比,经阴道彩超可有效避免了腹部器官、脂肪层厚及肠气的影响,临床诊断符合率高,两者结合应用,对子宫瘢痕处早期妊娠的诊断有较高的应用价值,值得推广应用。
Objective To investigate the diagnostic value of transabdominal and transvaginal color Doppler ultrasound in the early pregnancy diagnosis of uterine scar. Methods Retrospective analysis of 30 cases of early pregnancy diagnosed with uterine scar in the abdominal and transvaginal ultrasound imaging sonogram. Results The coincidence rate of transvaginal ultrasound examination was 66.67%. The coincidence rate of transvaginal ultrasound examination was 93.33%. The coincidence rate of transvaginal ultrasound diagnosis was significantly higher than that of transabdominal color Doppler ultrasound. The difference was statistically significant (P <0.05). Among 30 patients with uterine scar pregnancy, 19 cases were gestational sac type, 9 cases were heterogeneous fast pack type and 2 were mixed type. The difference was mainly manifested in the lower part of anterior wall of uterus and peripheral blood flow Different signals. Conclusion Compared with the transabdominal ultrasound, transvaginal ultrasound can effectively avoid the abdominal organs, fat layer thickness and intestinal gas, the clinical diagnosis of high coincidence rate, the combination of the two, the diagnosis of uterine scar early pregnancy is higher Application value, it is worth to promote application.
