Bilateral tubal ectopic pregnancy after spontaneous conception

Abstract

Objective: Presentation of a case report of a rare case of bilateral tubal pregnancy in a female patient after spontaneous conception. Observation: We present a case of a 26-year-old female patient first hospitalized in the Gynecology Obstetrics Clinic of the Pilsen University Hospital, where a laparoscopy was indicated for suspicion of ectopic tubal pregnancy during which a left-sided salpingectomy was performed for a macroscopically clear finding of a tubal pregnancy on the left side, this finding was also confirmed histologically. Subsequently, the patient was discharged to home care. During a follow-up examination by a district gynaecologist, the patient complained of a recurrence of pain in the lower abdomen, on collection of hCG (human chorionic gonadotropin) its increase was detected and the patient was sent for a control gynaecological examination to Mulacova Hospital in Pilsen. On the examination in the outpatient clinic, she reported significant lower abdominal pain and collapsed during transvaginal ultrasound and was hospitalized. Subsequently, diagnostic laparoscopy was indicated during hospitalization, during which tubal pregnancy on the right and hemoperitoneum were macroscopically evident. A right-sided salpingectomy was performed for this finding with subsequent hCG drop, resolution of the discomfort and histological confirmation of tubal pregnancy on the right. Conclusion: The incidence of such cases without prior ovulation stimulation is 1 out of 200,000 pregnancies and an estimated 1 out of 725 to 1 out of 1,580 ectopic pregnancies. Even so, bilateral tubal or heterotopic ectopic pregnancy should be considered in the differential diagnosis, as both conditions can be immediately life-threatening. Key words: bilateral tubal pregnancy – ectopic pregnancy – heterotopic pregnancy
