Near fatal interstitial pregnancy

Interstitial pregnancies are a rare form of ectopic pregnancy that occur when there is implantation of a fetus into the interstitial portion of the uterus. These can be particularly challenging to diagnose and have a high risk of morbidity and mortality due to the relatively late presentation compared to other ectopic pregnancies. Here we present a gravida 3, para 2 female patient at 14 weeks gestational age who suffered uterine rupture and hemoperitoneum leading to cardiac arrest in the Emergency Department. This case demonstrates the importance of ultrasound as a critical tool in the diagnosis of interstitial pregnancy and the sonographic findings. It is essential for emergency clinicians to be aware of this rare diagnosis. (C) 2022 Elsevier Inc. All rights reserved.
