近些年,随着选择剖宫产进行分娩数量的增多,剖宫产后的再次妊娠率也有所上升。剖宫产术后子宫切口瘢痕妊娠(CSP)发病率每年有所增加,已被视为剖宫产术后远期并发症之一,近年国内外均可见很多报道。CSP是一种危险类型的异位妊娠,如延误诊治会导致严重的并发症,甚至危及患者生命。因此,早期明确诊断,及时采取有效的措施终止妊娠,对于减少出血及患者预后甚为重要。目前,随着超声技术的不断发展、超声诊断仪分辨率的不断提高,在早孕期明确诊断CSP已成为可能。经阴道超声优越性在于高分辨力的探头近距离地接触被检查器官,可避免肠气干扰及腹壁脂肪层衰减的影响,经腹超声扫查范围更广泛,远场显示更清晰,两种途径联合应用,两者互补,发挥各自优势,为临床提供重要诊断依据。
In recent years, with the increase in the number of cesarean delivery, cesarean again after pregnancy rate also increased. The incidence of uterine incision scar pregnancy (CSP) after cesarean section has increased every year. It has been considered as one of the long-term complications after cesarean section. In recent years, many reports have been reported both at home and abroad. CSP is a dangerous type of ectopic pregnancy, such as delay in diagnosis and treatment can lead to serious complications, and even endanger the lives of patients. Therefore, a clear early diagnosis, timely and effective measures to terminate the pregnancy, to reduce bleeding and prognosis of patients is very important. At present, with the continuous development of ultrasound technology, the continuous improvement of the resolution of ultrasonic diagnostic apparatus, it is possible to make a definite diagnosis of CSP in early pregnancy. The superiority of transvaginal ultrasound lies in that the high-resolution probe closely contacts the organs to be inspected to avoid the influence of intestinal gas disturbance and the attenuation of abdominal fat layer. The transabdominal ultrasound scan has a broader scope and the far-field display more clearly. Both of the two approaches Joint application of the two complement each other to play their respective advantages for the clinical diagnosis to provide an important basis.
