Diagnosis of an Interstitial Pregnancy with 3-dimensional Transvaginal Sonography / 대한주산의학회잡지

ABSTRACT

Interstitial pregnancy is an ectopic pregnancy which is located in the intramural portion of the tube covered by myometrium. Rupture usually results in catastrophic hemorrhage, since there is an anastomosis of uterine artery and tuboovarian vessels. Therefore, the early diagnosis is important to decrease maternal morbidity. However, the diagnosis using the conventional 2-dimensional transvaginal sonography has some difficulties in differentiation from corneal pregnancy. In this case, we diagnosed an interstitial pregnancy using the 3-dimensional sonography in a woman with amenorrhea for 7 weeks and 1 days, which was resected through laparoscopic operation. The 3-dimensional sonography has a potential role to define the location of pregnancy implanted on the outer site of uterine fundus.
