A Case of Cornual Curettage Under the High-resolution Ultrasound Guidance / 대한주산의학회잡지

ABSTRACT

Cornual or interstitial pregnancy is a rare form of ectopic pregnancy. In previous reports it accounted for 2~6% of all ectopic pregnancies. Because this unique anatomic location of the implantation site is a highly vascular area, potentially catastrophic hemorrhage from uterine rupture may occur in 15~20% of the cases, and early diagnosis is very important. As sensitive serum beta-hCGmeasurement and imaging techniques have evolved, it is possible to diagnose cornual pregnancies earlier than in the past. Traditional management is cornual wedge resection or hysterectomy by laparotomy. But this invasive treatment method may increase the morbidity and the risk of uterine rupture in subsequent pregnancies, medical treatment with methotrexate has been applied to treat cornual pregnancies, offering an alternative to surgery. Also there have been case reports of laparoscopic treatment of cornual pregnancy. We report a case of viable cornual pregnancy, which was treated successfully by curettage of the uterine cornus under the guidance of high-resolution ultrasound.
