AbstractPrimary retroperitoneal ectopic pregnancy repre-sents an extremely unusual entity with a rather obscure patho-genesis. Implantation in the retroperitoneal space has been reported to occur both spontaneously and with use of assisted reproduction techniques. The pelvic and the upper retroperitoneum have both been involved, and implantation in
the most unusual anatomic sites has been reported. The major-ity of retroperitoneal gestations are located close to large blood vessels, and laparotomy is performed because of the high risk of massive hemorrhage. Few cases have been treated with laparoscopy so far. We report the case of an early first-trimester retroperitoneal broad ligament live pregnancy occur-ring after spontaneous conception in a patient who had a history
of an ipsilateral tubal ectopic pregnancy, previously treatedwith laparoscopic right salpingectomy. Current gestation had been missed during initial laparoscopy, andwas located and removed during a repeat laparoscopic procedure under intraoperative
ultrasonographic guidance
