Abdominal Pregnancy causes

Primary peritoneal pregnancy is rarely, its cause unknown,but some scholars think there is peritoneal epithelium into vice mesonephric duct epithelium probably, especially within the abdominal or pelvic have ectopic endometrial implantation,existence of fertilized eggs develop into the original hair of abdominal pregnancy.

Secondary abdominal pregnancy occurred in the vast majority of ruptured tubal pregnancy or after abortion, pregnancy or umbrella since the breakdown of the Department but some are still affixed to the Department of the villi affected area plant survival and dependent on or near the peritoneal organs continue to develop and become intra-abdominal pregnancy. Occurred in a small number of ovarian ectopic pregnancy after rupture, as once again done cesarean section incision dehiscence after pregnancy, fetal outbound to intra-abdominal, or other causes of uterine incision, the uterus can also happen, such as intra-abdominal fistula rare of Abdominal Pregnancy. Abdominal pregnancy because the placenta attached to different parts of the uterus under normal conditions the placenta attached to the blood supply of its very bad, so bad fetal development are also able to survive to full term only 5% ~ 10%, and the remaining majority of deaths at different gestational age in intra-abdominal, and its soft-tissue absorption, bone is residual, or

Mummy of, petrochemical, and also due to the formation of abscess secondary infection to the surrounding tissue, such as maternal umbilical, intestinal Vagina, thus there is fetal bone chip from hair, assist in the diagnosis of some.

Pathogenesis:
Fertilized egg to the original hair peritoneal factors in the plant has two kinds: ① coelom epithelium with transformation capacity to develop into a similar vice mesonephric duct epithelial organization, the peritoneal surface after uterine decidual reaction can be seen often are proved to have transformed epithelial body cavity probably basis; ② endometrial peritoneal surface plant at the plant in favor of a fertilized ovum.

Secondary abdominal pregnancy is more common than primary. Refers to abortion or ruptured tubal pregnancy, pregnancy cavity logistics, plant or other organs in the peritoneal surface, or completely divorced from the fallopian tube and continue to be the blood supply in intra-abdominal growth and development. Secondary abdominal pregnancy can also be secondary to ovarian or intra-uterine pregnancy. Because the uterus has on defect (such as cesarean section, caesarean births check, Hysteromyoma stripping of scar surgery) or spontaneous rupture of the uterus and peritoneal fistula, uterine diverticulum or primordial development of poor uterine natural breakdown of pregnancy by breaking fistula by mouth or intra-abdominal extrusion flows. Continued growth and development for intra-abdominal pregnancy.
