A ruptured 17 week right cornual gestation after failed termination of pregnancy

Cornual (interstitial) pregnancy is one of most hazardous type of ectopic pregnancy. it constitutes 2-4% of all ectopic gestations and may represent clinically stable until late gestational periods. in this case report, a ruptured right cornual gestation at the 17th week of gestation, following failed termination of pregnancy was presented. a 29-year-old woman, g2p1, presented to the emergency department with acute abdominal pain lasting for 12 hours. her blood pressure was 50/20 mmhg, heart rate was 110 bpm. emergent laparatomy was performed. in laparatomy, hemoperitoneum was observed. intraoperatively, we encountered a right lateral wall ruptured uterus with a 17 week old fetus in the peritoneal cavity, suggesting a right cornual ectopic pregnancy which ended up as a catastrophic event. a cornual resection and repair was done successfully.
