随着诊疗技术的提高及性观念的改变,异位妊娠的发生率较前有所升高,据相关报道,异位妊娠的发生率在1%左右。但是据报道美国异位妊娠的发生率占全世界妊娠妇女的2%,且呈增长趋势~([1])。异位妊娠(ectopic pregnancy,EP)是指受精卵在宫腔以外的位置着床生长,着床部位多样,95%发生与输卵管部,也可着床在卵巢、腹腔、宫角等部,而且随着剖宫产率的升高,剖宫产瘢痕部位的妊娠也较前多见。对于异位妊娠逐渐升高的发病率,确定异位妊娠发生的危险因素对于制定切实可行的干预措施尤其重要。
With the improvement of diagnosis and treatment techniques and changes in sexual attitudes, the incidence of ectopic pregnancy increased compared with the previous, according to reports, the incidence of ectopic pregnancy is about 1%. However, it is reported that the incidence of ectopic pregnancy in the United States accounts for 2% of the pregnant women in the world and shows an increasing trend ([1]). Ectopic pregnancy (EP) means that the fertilized egg implants and grows outside the uterine cavity with various implantation sites, with 95% occurring in the fallopian tube part and also in the ovary, abdominal cavity, and horn of the horn, etc. With the increase of cesarean section, cesarean section scar pregnancy more common. For the increasing incidence of ectopic pregnancy, identifying risk factors for ectopic pregnancy is particularly important in developing practical interventions.
