Abstract:
Interstitial pregnancy is a rare but life-threatening condition. It is usually treated using cornual resection at operative laparoscopy or laparotomy; however, this may adversely affect future fertility and pregnancy. Transcervical suction using an 8F pediatric catheter placed through the cornua under laparoscopic and hysteroscopic guidance may be possible in some patients if the pregnancy is accessible vaginally. We describe a case of interstitial pregnancy treated with transcervical suction using an 8F pediatric catheter placed through the cornua under laparoscopic and hysteroscopic guidance with preservation of the uterine cornua and fallopian tube. The procedure was quick, bleeding was minimal, and there were no complications. Removal was complete, and serum beta-human chorionic gonadotropin quickly became undetectable. Three months after the operation, salpingography yielded normal findings, and the patient was pregnant again 8 months after the surgery.
