Management and Outcome of a 14-Week-6-Day Ruptured Interstitial Ectopic Pregnancy with Intact Amniotic Sac in a Resource-Limited Setting

Background: Interstitial ectopic pregnancy is a rare form of ectopic pregnancy, accounting only for 2 to 3 % of cases. The mortality rate is 6-7 times higher than that in classic ectopic pregnancy. Most cases of interstitial ectopic pregnancy always present with rupture due to the challenges of clinical and radiologic diagnosis. Surgery remains the treatment of choice when rupture and hemodynamic instability occur. This report aimed at presenting a very rare case of ruptured interstitial ectopic pregnancy. Case Presentation: A 27-year-old sub–Saharan African woman presented to our health facility with cramping abdominal pain associated with vomiting, fatigue, and dizziness. She was diagnosed with an advanced ruptured interstitial ectopic pregnancy at 14 weeks 6 days with a pelvic ultrasound. A laparotomy was done, and her recovery was uneventful. Conclusion: Interstitial ectopic pregnancy remains a rare type of ectopic pregnancy that is rarely reported, let alone extending beyond the early second trimester. Early diagnosis and timely surgical intervention are essential to prevent life-threatening complications. This case highlights the importance of integrating clinical, imaging, and laboratory findings in the diagnosis of advanced ectopic pregnancy.
