Successful Management of a Ruptured Interstitial Pregnancy: A Case Report.

Interstitial pregnancy is a rare entity that usually leads to the rupture of the uterus. The difficulty and delay in diagnosing this condition have been reported to cause high mortality rates. Here, we present the case of a 36-year-old woman who presented to the emergency department with severe epigastric pain and hemodynamic instability. Her current gestational age (GA) could not be accurately measured as she was unbooked and had irregular periods. However, by abdominal examination, the GA was estimated to be 38 weeks, whereas by ultrasound it was approximately 28 weeks. It was also noted that the uterus was empty, and the fetus was found in the abdominal cavity. Hence, a working diagnosis of uterine rupture was made and the patient was taken for emergency laparotomy. The patient delivered an alive 1.2 kg baby. Intraoperatively, the placenta was implanted in the interstitial part of the right fallopian tube. The placenta was then excised and right salpingectomy was performed, following which the abdomen was closed in layers. Postoperatively, the patient made an uneventful recovery and was discharged home in stable condition; however, the baby passed away due to complications related to extreme prematurity.
