“…When implantation is made in this area, the gestational sac is protected by the muscle layer of the uterus, and the pregnancy lasts longer than other tubal pregnancies. 5,6 However, the chorionic villi invade the blood vessels in the uterine cornu, causing massive bleeding, which is associated with maternal mortality and morbidity. Rupture of cornual pregnancy mostly occur between 8and 16-weeks gestational age.…”

“…The findings that can be diagnosed with ultrasound in uterine cornus are as follows; first, there was no gestational sac in the uterine cavity, second, the distance between the chorionic sac and the outer side of the uterine cavity is more than 1cm apart, and third, a thin uterine muscle layer must surround the chorionic sac. [6][7][8][9][10][11][12] In intrauterine pregnancy, the uterine muscle completely encloses the gestational sac, but in cornual pregnancy, the uterine muscle covers the gestational sac with a thin rim. On ultrasound, when the gestational sac is located in the uterine cornus, or is at the lateral part of uterine fundus, and clinically suspected intraperitoneal bleeding, a diagnostic laparoscopy should be performed immediately.…”

Objective of the study was to report a case of cornual pregnancy at 10 weeks gestational age, accompanied by heterotopic pregnancy. A 41-year-old woman was transferred to the emergency department of the national health insurance service Ilsan hospital at amenorrhea 10 weeks 5 days after being diagnosed of cornual pregnancy from a primary hospital. The patient was nulliparous with a history of 1 induced and 2 missed abortions. Other than a previous myomectomy, her medico-surgical history was not significant. She was initially diagnosed with blight ovum at amenorrhea 8 weeks 4 days, and dilatation and curettage were performed at the primary hospital of which she was referred from. At amenorrhea 10 weeks 5 days, another gestational sac was noted at the left cornu of the uterus by ultrasonography. The tentative diagnosis was cornual pregnancy accompanied by heterotopic pregnancy. Serum ß human chorionic gonadotrophin (hCG) at the time of arrival was 84573.8 mIU/ml. Trans-abdominal ultrasonography showed a mass protruding from the left cornu of the uterine cavity, containing a gestational sac (mean sac diameter 39.0 mm, 10 weeks size) and an embryo of cranio-caudal length of 38.2 mm (10 weeks 5 days size). There was no sign of intraperitoneal hemorrhage. Emergency operation was planned under the diagnosis of cornual pregnancy. Entering the abdominal cavity, a 5×5 cm sized conceptual mass surrounded by thin and fragile myometrium was noted on left uterine cornu. Open wedge resection of the left cornual pregnancy with left salpingectomy was performed. The resected mass was 4.0×3.5 cm2 in size. An embryo with 45 mm size was confirmed inside the mass.

“…1,5,7 Transvaginal sonography has enabled early diagnosis of interstitial (cornual) pregnancies in which an ectopic gestation is located within the uterine myometrium, eccentric to the endometrial cavity. [8][9][10] Sonographic criteria for this condition include an eccentrically located gestational sac surrounded by a myometrial mantle distinctly separate from the endometrial cavity. [8][9][10] The presence of a yolk sac, an embryo, or fetal cardiac activity within the intramurally located gestational sac is considered diagnostic.…”

“…In addition, the widespread use of prenatal ultrasonography has defined a group of women who have a greater risk for bleeding. [1][2][3] These women often have abnormal placental-uterine implantation resulting in placenta accreta, placenta percreta, or placenta increta. These abnormalities have become more common with the increased use of cesarean section, which is associated with a higher incidence of these complications in subsequent pregnancies.…”

Emergency uterine artery embolization for serious obstetrical hemorrhage has proved to be a useful technique. Protocols between obstetricians and interventional radiologists that have been established allow the effective management of these young women in what may be life-threatening situations. ObjectivesAfter reading this article, the reader should 1) know what protocals to use for emergency obstetrical hemorrhage, and 2) be familiar with methods of uterine artery catheterization.
