Right angular pregnancy at seven weeks' gestation: a case report treated by laparoscopic approach.

Angular pregnancy (AP) or implantation of the embryo in the lateral angle of the uterine cavity close to the internal ostium of the fallopian tube is a very rare event. In fact, angular pregnancy refers to implantation of the embryo just medial to the uterotubal junction, in the lateral angle of the uterine cavity. AP must be distinguished, anatomically, from interstitial pregnancy by its position in relation to the round ligament, which crosses the Müllerian duct at the side of the uterotubal junction. AP is associated with a high rate of complications such as bleeding and ruptured uterus due to delayed diagnosis. The authors present a clinical report of AP at seven weeks' gestation without uterine rupture. They performed directly operative laparoscopy because of acute intra-abdominal hemorrhage. Laparoscopy was useful in the treatment of early angular pregnancy and could avoid the need for invasive surgery or hysterectomy.
