Third trimester tubal pregnancy. A case report.

BACKGROUND

A viable tubal pregnancy is an extremely rare occurrence with an increased risk of fetal as well as maternal morbidity and mortality. We report a third trimester tubal pregnancy occurring after an interval tubal ligation.

CASE: A 43-year-old woman, gravida 2 para 1, presented at 29 weeks' gestation with an asymptomatic extrauterine pregnancy and was managed expectantly in the antepartum unit. At 33 weeks the fetus was delivered for worsening umbilical artery velocimetry. Despite aggressive resuscitative efforts, the neonate did not survive.

CONCLUSION

In managing an advanced extrauterine pregnancy, imaging with MRI may help diagnose and confirm suspicion raised by ultrasonography and may aid in presurgical planning and management. This case illustrates the diagnostic challenge and high neonatal mortality of an advanced tubal pregnancy.
