A Case of Ruptured Left Interstitial Ectopic Pregnancy

Although rare, interstitial ectopic pregnancy poses a challenge in diagnosis and management. The pregnancy is implanted in the interstitial part of the fallopian tube, i.e., the proximal intramural portion. When ruptured, it results in a catastrophic event; the rupture can involve the uterine wall, as in this case, which puts the prognosis of future pregnancies at risk. Here, a case of a 35-year-old primigravida who conceived after ovulation induction is reported. Her diagnosis of ectopic pregnancy was missed; it was misdiagnosed as incomplete abortion followed by dilatation and evacuation. Post-evacuation severe pain and hemodynamic instability, and subsequent ultrasonography (USG) lead to the diagnosis of left interstitial ectopic pregnancy. Emergency laparotomy, left salpingo-oophorectomy, and cornual resection with repair were done.
