目的探讨经阴道彩色多普勒超声对剖宫产切口瘢痕妊娠的诊断价值。方法 12例剖宫产切口瘢痕妊娠经手术病理及保守治疗所证实,根据声像图特征进行回顾性分析。结果孕囊型8例,混合回声型4例,声像图特征表现为子宫下段前壁内可见孕囊或包块,与膀胱之间肌层变薄,彩色多普勒显示包块内及周边见丰富血流信号,脉冲多普勒呈高速低阻型频谱。结论经阴道彩色多普勒超声能清晰显示剖宫产术后切口瘢痕妊娠的位置、分型、范围,子宫肌层厚度及血流情况,诊断及时,并能动态观察,具有重要临床应用价值。
Objective To investigate the value of transvaginal color Doppler ultrasound in the diagnosis of cesarean scar pregnancy. Methods Twelve cases of cesarean scar pregnancy were confirmed by surgical pathology and conservative treatment, and retrospectively analyzed according to sonographic features. Results The gestational sac-type in 8 cases, mixed echo in 4 cases, the sonographic features of the lower wall of the anterior wall of the uterus visible gestational sac or mass, and between the bladder thin, color Doppler display within the mass See rich blood flow signals, pulsed Doppler showed high-speed low-impedance spectrum. Conclusion Transvaginal color Doppler ultrasound can clearly show the position, type, range, myometrial thickness and blood flow of incisional scar pregnancy after cesarean section. It has important clinical value in diagnosing timely and dynamically.
