A RARE CASE OF AN INTERSTITIAL PREGNANCY

Abstract

In ectopic pregnancy, implantation of the zygote occurs outside of the endometrial cavity. Interstitial pregnancy has an incidence of 2-4% of all ectopic pregnancies. We present a clinical case of interstitial pregnancy. On 20.10.2023, a woman visited the University Hospital "St. Marina" - Pleven, Bulgaria, because of a positive morning pregnancy test. The patient was a 30-year-old woman. The last menstrual period was on 12.09.2023. Two consecutive vaginal ultrasonography were made every 10 days. No fetal sac was visualized in the uterine cavity. The second ultrasonography visualized a hyperplastic endometrium, 21 mm thick. A fetal sac located interstitially was found high in the right uterine horn. The ß-hCG values were 412 mIU/ml and 12490 mIU/ml, respectively. The patient was referred for a pelvic MRI, which confirmed the diagnosis. After discussion and informed consent signed by the patient, on 30.10.2023 at University Hospital "St. Marina" - Pleven, Bulgaria, under general anesthesia on 30.11.2023, a Laparotomia a modo Pfannenstiel. Resectio cornualis dextra. Extirpatio graviditas interstitialis dextra. Salpingectomia dextra. Sutura uteri. Lavage. Drainage. Abrasio probatoria was performed. The patient tolerated the surgical intervention well. The histological result proved interstitially located ectopic pregnancy. In cases of interstitial pregnancy, early diagnosis is crucial for successful treatment and health of the patient.
