A cornual pregnancy is an ectopic pregnancy that develops in the interstitial portion of the fallopian tube invading through the uterine wall. Cornual pregnancies often rupture later than other tubal pregnancies because the myometrium is more distensible than the fallopian tube. Increased vascularity associated with interstitial ectopic pregnancies is more likely to result in a catastrophic hemorrhage and death. The mortality rate of interstitial pregnancy is more than twice that of other tubal pregnancies. We report a case where cornual pregnancy was diagnosed at 18 weeks of gestation after uterine rupture and profound hemorrhage occurred. The patient underwent hysterectomy. Close monitoring of pregnancies in these patients is important to prevent a deleterious delay in treatment of a cornual pregnancy.
Cornual pregnancy is a rare form ectopic pregnancy. Interstitial pregnancies account for 2–4 % of ectopic pregnancies and that 20 % of cases that advance beyond 12 weeks of gestation end in rupture [
We report a case where cornual pregnancy was diagnosed at 18 weeks of gestation after uterine rupture and profound hemorrhage occurred.
A 32-year multigravida, G:2, P:1, presented in our clinic with the complaint of an acute lower painful abdomen at 17 + 5 weeks of gestation. She had severe abdominal pain 4 hours before admission. Her temperature was 35.3 °C, blood pressure (BP) 70/40 mmHg and pulse rate 72 beats/min. The lower abdomen was firmly tender with rebound. On her pelvic examination slightly enlarged uterus and cervical tenderness on motion had been detected. The initial laboratory tests included haemoglobin 7.5 g/dL, hematocrit 22.3 %. Platelet count, bilirubin, alanine and aspartate transaminase and alkaline phosphatase were within normal limits. Her past medical was not history was not informative, she had had an uncomplicated normal spontaneous vaginal delivery at term. She had no risk factors for ectopic pregnancy. On the abdominal ultrasonography, the endometrial cavity was empty and a 18-week-old viable fetus with gestational sac (FL: 24mm:17W1D, BPD: 39mm:18W) was depicted in the abdomen with massive free fluid. An emergency laparotomy was performed under general anesthesia. There was approximately 4000 ml of blood in the abdominal cavity with a male fetus (15.25 cm length, 192 g) protruded from the right ruptured cornual region. The rupture measured about 12-13 cm in diameter, and placental tissue protruded through it (Figure1 and 2). Normal left fallopian tube and, both ovaries were seen. Hysterectomy was done. Peroperatively, in total she had received 5 units of red blood cells and 2 units of fresh frozen plasma. The postoperative course was uneventful, and she was discharged on postoperative day 6 in good condition.
The etiologic factors for cornual pregnancy are pelvic inflammatory disease, tumor, a high number of transferred embryos, a transfer near the uterine horn, excessive pressure on the syringe during the transfer, or difficulties during the ET procedure [
Cornual pregnancy is diagnosed with ultrasonographical criteria in the presence of a positive hCG level indicating pregnancy [
At a later gestation or after rupture, laparotomy with hysterectomy or cornual resection have been traditionally treated the cornual pregnancies. When an unruptured cornual pregnancy is diagnosed, there is a variety of conservative management options, such as medical management with methotrexate applied by parenteral route or directly injection of methotrexate or potassium chloride into the cornual gestational sac with ultrasonography guidance, laparoscopic cornual resection, and selective uterine artery embolization when conservative treatment with uterine preservation is desired [
