Primary abdominal pregnancy with implantation on the posterior cul-de-sac area is a very rare form of ectopic pregnancy that involves nonspecific clinical symptoms and physical findings, making early diagnosis very difficult. Whereas diagnostic laparoscopy can be performed in suspicious of abdominal pregnancy for accurate diagnosis and treatment, complete ligation of the vessel supplying blood to the placenta during surgery is often difficult. In many cases, there is continuous massive hemorrhage after litigation, significantly increasing maternal morbidity and mortality. We herein report with literature references a case of a 33-year-old female patient of primary abdominal pregnancy with implantation on the posterior cul-de-sac area. She showed hemostatic failure in a blood vessel after undergoing a surgery to remove the gestational sac, and was successfully treated with additional transcatheter arterial embolization.
