Obstetric morbidity and the diagnostic dilemma in pregnancy in rudimentary horn: retrospective analysis.

BACKGROUND

Pregnancy in rudimentary horn of uterus, a form of ectopic gestation, is associated with significant rates of morbidity and mortality. Despite the recent advances in the ultrasonography, diagnosis of cornual pregnancy still remains elusive; with confirmatory diagnosis usually made during laparotomy. The aim of the present study is to analyze the obstetric implications and the diagnostic dilemma of rudimentary horn pregnancy.

MATERIALS AND METHODS

Records of women diagnosed with ectopic pregnancy in the rudimentary horn, during the years 2004 to 2008, managed in a referral hospital in northern India; were reviewed for their diagnostic difficulties and the associated morbidity.

RESULTS

During the four year study period, rudimentary horn pregnancies accounted for 12 pregnancies. Non communicating horn accounted for 75% of the cases. The mean age of women at presentation was 26 +/- 5.11 years and the period of gestation at diagnosis varied between 10 and 34 weeks. Preruputure diagnosis was possible only in two cases and sensitivity of ultrasonographic diagnosis was 33.3%. Laprotomy with excision of rudimentary horn and salpingectomy was done in all cases. Multiple blood transfusions were required in 83.3% of women.

CONCLUSION

Management of pregnancy in a rudimentary uterine horn continues to be a challenge to this day. Maintaining a higher degree of alertness, especially in high risk groups by emergency staff is required to prevent the morbidity, as they may present with acute uterine rupture in pregnancy.
