剖宫产瘢痕妊娠(CSP)是指胚囊着床于既往子宫切口瘢痕处,是剖宫产远期并发症之一[1]。近年随着剖宫产率的升高,剖宫产术后瘢痕妊娠发病率有上升趋势,且常被误诊为宫内妊娠或不全流产而行清宫术,发生大出血。超声能通过对较特异性图像辨认,对最关键的早期诊断及早期治疗起重要作用。现将我院2008年至2010年收治3例剖宫产瘢痕妊娠病例分析如下。 Cesarean scar pregnancy (CSP) refers to implantation of embryo sac in the previous incision scar, is one of the long-term complications of cesarean section [1]. In recent years, with the increase of cesarean section rate, the incidence of scar pregnancy after cesarean section has an upward trend, and is often misdiagnosed as intrauterine pregnancy or incomplete abortion and curettage, the occurrence of major bleeding. Ultrasound through the more specific image recognition, the most critical early diagnosis and early treatment play an important role. Now in our hospital from 2008 to 2010, 3 cases of cesarean scar pregnancy were analyzed as follows.
