Primary peritoneal pregnancy

Early Abdominal Ectopic Pregnancies: A Systematic Review of the Literature

“…Cavanagh [168] postulated that fertilization may occur in the posterior cul-de-sac where sperm is known to accumulate and that an ovum could lay there due to dependent flow of peritoneal fluid. Paternoster and Santarossa [110] further postulated that the ‘... dynamics of intraperitoneal fluid flow may carry the zygote from the cul-de-sac to different bizarre intraperitoneal sites’.…”

Primary Abdominal Pregnancy in the Uterosacral Ligament with Haemoperitoneum: A Near Miss

“…The probable pathophysiology is the occurrence of fertilization in the rectouterine pouch, where sperms are known to accumulate and where the ovum lies due to dependent flow of peritoneal fluid [10]. [Table/ Fig-4] depicts the characteristics of the reported cases of pregnancies which had occurred in the uterosacral ligament.…”

Splenic Gestation: A rare case report

“…9 Cavanagh proposed the postmature ovum as the one where intra tubal fertilisation takes place but reflux occurs resulting in primary ovarian or peritoneal pregnancy. 10 However it is more likely that the ovum matures early, becomes fertilised within the abdominal cavity, thereafter failing to achieve entry through the tubal ostium.…”

“…Additionally, the presence and quality of cilia, the smooth muscle activity and differential blood flow in the fimbrial folds, all may be distorted by physical or hormonal changes caused by prior salpingitis even though the damage histologically may not be severe. 10 The other identified risk factors for ectopic pregnancy include very young or old age, previous ectopic pregnancy, previous pelvic surgery, tubal pathology, tubal sterilisation, history of pelvic inflammatory disease, use of IUD, smoking, infertility, IVF and other assisted reproductive techniques. In our case however, none of the risk factors were identified.…”
