一、引起输卵管妊娠的输卵管病理生理:输卵管妊娠的原因是多样的,但阻碍或延迟受精卵抵达宫腔的各种因素被认为是最主要的。1.输卵管炎症:输卵管炎症使输卵管粘膜的皱襞相互粘连形成盲腔,或使输卵管壁纤维化,管腔狭窄,或引起输卵管周围炎,扭曲输卵管的正常通道。文献报道,镜下见到输卵管有炎症证据者占19～95%。1970年Persaud 等用X 线及病理检查发现输卵管妊娠的输卵管壁中49%有憇室形成,这些憇室的病理表现是在管壁内见到有内衬上皮的腔隙,其中充满钡剂,有管腔相通,有时伸延至浆膜面,这些憇室的形成多在峡部及壶腹部,是输卵管妊娠的常见部位,其形成的原因不明,炎症也是一个主要因素。2.输卵管功能失调:输卵管痉挛或无力使运送受精卵的功能失调。1983年Winston 等用扫描电 First, tubal pregnancy induced tubal pathophysiology: tubal pregnancy is due to a variety of reasons, but hinder or delay fertilized eggs arrived in the uterine cavity of various factors is considered to be the most important. 1. Tubal inflammation: tubal inflammation of the tubal mucosa folds caused by adhesion to each other to form a blind cavity, or tubal fibrosis, stenosis, or cause tubal inflammation, twisted the normal fallopian tubes. Reported in the literature, tubal tubal inflammation to see evidence of 19 to 95%. Persaud 1992 X-ray and pathological examination revealed tubal pregnancy, 49% of the tubal wall formation, the pathological manifestations of these cholera is seen in the wall lined with epithelial cavity, which is full of barium, There are lumen interlinked, and sometimes extended to the serosal surface, the formation of these 憇 room and more in the isthmus and ampulla, tubal pregnancy is a common site, the formation of unexplained, inflammation is also a major factor. 2. Tubal dysfunction: tubal spasm or inability to transport fertilized egg dysfunction. 1983 Winston and other scanning electricity
