An Unusual Case of Spontaneous Uterine Rupture After a Salpingectomy Following an Interstitial Ectopic Pregnancy

Abstract

Spontaneous uterine rupture following a history of surgical treatment of an interstitial tubal ectopic pregnancy (EP) is a rare clinical form. This uterine rupture occurring after a wedge resection of the uterine horn, is a serious obstetric complication involving maternal and fetal vital prognosis and obstetric fate of patients in the absence of immediate management. Our observation concerned a 32-year-old gestant, G3P1 (without living children), with a history of interstitial EP dating back to 3 years during which a uterine wedge resection was performed. For this patient, a prophylactic caesarean was recommended between 36 and 37 weeks of amenorrhea. The patient presented during her prenatal follow-up at 37 weeks and 6 days, a complete uterine rupture involving the right uterine horn with the death of a fetus weighing 2900g. The rupture extended throughout the uterine horn, with the right uterine pedicle intact and the right fallopian tube absent. A conservative treatment of the uterus was decided since the patient had no living children. The purpose of our observation is to recall the risk of uterine rupture after cornual uterine excision hence the importance of performing during a EP if possible, a salpingectomy at the level of the uterine horn and if necessary coagulate the intramural portion of the tube. And also in case of uterine wedge resection, to hasten the prophylactic caesarean section as soon as sufficient maturity of the fetus to reduce the incidence of this pregnancy complication.
