Rupture of non-communicating rudimentary horn at 35 weeks ending with a live birth: A case report

Abstract

Introduction and importancethe rudimentary horn pregnancy frequently ruptured in the second and third trimesters during the normal process of rudimentary horn pregnancy (RHP) which results in a hemoperitoneum that may be fatal, however in very rare cases and under close observation, the pregnancy may continue and end with a live birth. Case presentationA 30 years-old woman gravida 3, para 4 with no symptoms presented to the hospital at 30 weeks gestation for a routine examination and misdiagnosed as an abdominal ectopic pregnancy. The pregnancy continued for approximately 35 weeks, when a ruptured rudimentary horn pregnancy was discovered accidently during an emergency surgery, the left fallopian tube and ovary and the ruptured rudimentary horn were removed. Clinical discussionUnicornuate uterus is a result of abnormal or failed development of one of the paired müllerian ducts, Spontaneous abortion in women with rudimentary horn pregnancy may occurs in the first and second trimester. Rudimentary horn pregnancies are associated with high maternal morbidity and mortality, And because of the risk of life-threatening complications, early diagnosis before rupture is essential for the successful management and prevention of these complications. ConclusionThe diagnosis of most cases of rudimentary horn pregnancy is considered challenging, and could be diagnosed after rupture, during emergency surgery. Although rudimentary horn pregnancy mostly ends in the first and second trimester, in some cases it may continue until term and end with a live healthy child.
