Pregnancy in a uterine rudimentary horn presents with an incidence of 1:100,000 pregnancies and carries a high risk of uterine rupture with severe and potentially lethal intra-abdominal haemorrhage. Accurate pre-operative diagnosis can be difficult. Limited published evidence suggests that such cases may be managed successfully by laparoscopy. A number of authors have used destructive techniques to the fetus following excision of the rudimentary horn, to extract the tissues laparoscopically. Pre-operative feticide is recommended in cases where morcellation of the fetus is
planned. We encountered a live unruptured 11-week rudimentary horn pregnancy in a woman with one previous normal delivery at term. We aimed to excise the pregnant rudimentary horn laparoscopically and avoid destructive techniques to ease the patient's concerns. At laparoscopy a particularly dilated vascular infundibulopelvic ligament was seen at the side of the pregnant horn.
