Laparoscopic Excision of a Rudimentary Uterine Horn with an Intra-Uterine Pregnancy at 9 6/7 Weeks' Gestation

Abstract

Study Objective: Pregnancy in a rudimentary uterine horn is a rare and potentially lethal condition. The highest risk of rupture is reported to be during the late first and then second trimester. The risk of rupture correlates with the thickness of the myometrium surrounding the fetal pole. In 2005, a 20-year-old lady was diagnosed by imaging studies and laparoscopy to have an absent right kidney, a bicornuate uterus with a right rudimentary uterine horn and a single cervix, a transverse vaginal septum with hematocolpos, and endometriosis secondary to reflux menstruation.
