Minimally Invasive Surgical Management of a Second Trimester Pregnancy in a Rudimentary Uterine Horn

Abstract

BackgroundPregnancy in a rudimentary uterine horn is a rare form of ectopic pregnancy with a high risk of rupture. Management usually involves excision of the rudimentary horn. If diagnosed after the first trimester, it has been managed in the past by laparotomy. CaseA primigravid woman was found on routine ultrasound to have a rudimentary horn pregnancy. The diagnosis was confirmed on MRI, and a thin uterine wall was demonstrated. Management comprised fetal injection of potassium chloride followed by complete laparoscopic excision of the rudimentary horn at 16 weeks’ gestation. ConclusionLaparoscopic management of a mid-trimester rudimentary horn pregnancy is feasible, but expert radiological characterization is required for optimal surgical planning.
