目的:探讨对剖宫产后瘢痕妊娠患者采用经阴道超声检查、经腹部超声检查对不同分型的诊断情况。方法:将我院妇产科收治的64例经组织学检查和手术结果证实为剖宫产后瘢痕妊娠患者进行观察,先后采用经阴道超声检查、经腹部超声检查,观察两种检查方法的诊断准确率。结果:64例瘢痕妊娠患者中孕囊部分突入型30例,孕囊完全突入型13例,混合团块型21例。经阴道超声诊断准确率为96.88%明显高于经腹部超声检查(P<0.05);且经阴道超声检查的漏诊率、误诊率均明显低于经腹部检查(P<0.05)。结论:经阴道超声检查可以准确判定瘢痕妊娠类型,为临床治疗提供科学依据,具有较高的临床应用价值。 Objective: To investigate the diagnosis of cesarean section scar pregnancy by transvaginal ultrasonography, abdominal ultrasound examination of different types of diagnosis. Methods: 64 cases admitted to our hospital obstetrics and gynecology confirmed by histological examination and surgical results for cesarean scar pregnancy patients were observed by transvaginal ultrasound, abdominal ultrasound, the two diagnostic methods were observed Accuracy. Results: In the 64 cases of pregnancy with pregnancy, 30 cases were invaded by gestational sac, 13 cases were completely penetrated by gestational sac, and 21 cases were mixed mass. The diagnostic accuracy of transvaginal sonography was 96.88%, which was significantly higher than that of transabdominal sonography (P <0.05). The rate of missed diagnosis and misdiagnosis of transvaginal sonography was significantly lower than that of transvaginal sonography (P <0.05). Conclusion: Transvaginal ultrasonography can accurately determine the type of scar pregnancy, provide a scientific basis for clinical treatment, and have high clinical value.
