Ovarian pregnancy rupture in second trimester manifesting mental change in pregnancy: a case report

Challenges of Management of Ruptured Second Trimester Ovarian Pregnancy in Low-and Middle-Income Settings: A Case Report

Background

Ovarian ectopic pregnancy is a rare form of non-tubal ectopic pregnancy. It can rupture before the end of the first trimester, causing hemoperitoneum, and present with signs and symptoms similar to other commoner abdominal emergencies or the pregnancy can continue intraperitoneally. Therefore, they are not often diagnosed preoperatively. Ultrasound can assist in diagnosis of ovarian ectopic pregnancy but the findings could be ambiguous or inconclusive. We present a case of ruptured ovarian ectopic pregnancy at the second trimester causing massive hemoperitoneum that was suspected as an intrabdominal malignancy co-existing with intrabdominal pregnancy.

Case presentation

She was a 34 year-old Nigerian unbooked G4P3+0, (3 alive), who presented to the labor ward on 21st January, 2021 with a complaint of a 6-week history of abdominal pain and swelling. Pain was insidious in onset, generalized, non-colicky, non-radiating, constant, no known aggravating or relieving factor, but it was of moderate intensity. She had amenorrhea with a positive serum pregnancy test without prior early ultrasound. At presentation, initial abdominopelvic ultrasound revealed intra-uterine viable pregnancy but repeat ultrasound done showed a left adnexal ectopic gestation and an echo-rich intraperitoneal fluid collection. Laparotomy was done and ovarian pregnancy was accurately diagnosed intra-operatively. Tissue samples from the ovary confirmed normal products of conception, namely chorionic villi, trophoblastic cells and ovarian stroma at histology.

Conclusion

Despite advances in imaging techniques, the diagnosis of ovarian ectopic gestation is still very difficult. When premenopausal women present with amenorrhea, generalized non-colicky abdominal pain and swelling in combination with ambiguous findings of pregnancy on ultrasound in the absence of trauma, differential diagnoses should include ruptured ovarian pregnancy. Obstetricians should maintain a high index of suspicion to forestall delayed diagnosis and the potential maternal morbidity and mortality. However, the need for high-index of suspicion should be for any ectopic, not just ovarian pregnancy.

Unruptured ovarian ectopic pregnancy: Two case reports and literature review

In clinical practice, ovarian pregnancy is extremely rare and is always found to be ruptured. A definitive diagnosis for ruptured ovarian pregnancy is difficult to obtain. We present two cases of unruptured ovarian pregnancies detected during laparoscopy and review existing literature to better understand the clinical characteristics of ectopic pregnancies in this rare site. Intrauterine devices, assisted reproductive technology, and intrauterine operations are all high-risk factors in ovarian pregnancy. Moreover, menopause, abdominal pain, and vaginal bleeding are clinical manifestations. Ovarian pregnancy can be diagnosed using serum hCG, transvaginal ultrasound, and magnetic resonance imaging. Laparoscopy is the treatment of choice for ovarian pregnancy. It is recommended that the intact gestational sac be excised and the ovarian function be protected to the greatest extent possible during the operation. More definitive diagnosis of ovarian pregnancy must be reported in order to gain a better understanding of ovarian pregnancy.

Rupture of Ectopic Ovarian Pregnancy Accompanied by Massive Intra-abdominal Bleeding and Disorder of the Coagulation Mechanism: A Rare and Life-Threatening Obstetric Complication

The rupture of ectopic ovarian pregnancy accompanied by massive intra-abdominal bleeding is a rare obstetric complication, occurs predominantly in the first trimester of pregnancy, and can be dangerous and life-threatening for the pregnant woman. Our case describes a 37yr old woman with a history of 4 lower segment Cesarian sections (LSCS) (Caesarean sections) and multiple surgical abortions, presenting at the ER with acute abdomen symptoms. The patient's hemodynamic status was unstable. The positive urine pregnancy test combined with the clinical and ultrasound findings established the diagnosis of the ruptured ectopic pregnancy, and immediate surgical treatment was decided. During surgery, a large amount of blood was found in the peritoneal cavity, resulting from a rupture of the right ovary and accompanied by hemorrhagic infiltration of adjacent tissues, without participation in the damage of the ipsilateral fallopian tube. It was deemed necessary to remove the ipsilateral adnexa and whole blood transfusion. The patient was discharged from our department on the fourth postoperative day. The price of beta-chorionic gonadotropic hormone was on a downward trend. Three weeks later, the level of beta-chorionic gonadotropic hormone was zero. In the present paper, a brief review is attempted regarding the diagnostic and therapeutic approach for patients with ruptured ectopic ovarian pregnancy after describing the case.

Catch Me While You Scan: Primary Ovarian Pregnancy

Primary ovarian pregnancy is rare, accounting for 0.5%–3.0% of all ectopic gestations. It was earlier diagnosed by the classical Spiegelberg's criteria. Ultrasonographic diagnostic criteria have now been described for preoperative diagnosis. We report a case of primary ovarian pregnancy in a 30-year-old woman, where the diagnosis was made preoperatively, and discuss the challenges in diagnosis and management for optimal patient outcomes.

An investigation of the time trends, risk factors, role of ultrasonic preoperative diagnosis of 79 ovarian pregnancy

BACKGROUND

Ovarian pregnancy (OP) is a rare form of ectopic pregnancy and is still a medical challenge. Therefore, more studies about the time trends, risk factors and diagnostic measurements are needed for the efficient treatment of OP.

METHODS

The datum of OP patients who were treated at the Second Hospital of Hebei Medical University from 2003 to 2018 was collected and a retrospective cohort study was preformed between OP and tubal pregnancy.

RESULTS

79 of all 6943 ectopic pregnancy (1.14%) were OP. The prevalence of OP following assisted reproductive technology showed an increasing trend over time, from 8.33% to 15.22%. Previous abdominal surgery was one of the risk factors of OP (OR 0.41, 95% CI 0.18-0.95, p = 0.04). Merely 2 (2.53%) patients were sonographically diagnosed as OP accorded with their discharge diagnosis. However, 56 (80.0%) accumulation of blood in the pelvis formed echo free areas could be clearly found by ultrasonography. A significant difference was found in serum β-hCG level among OP patients and tubal pregnancy patients (2762.73 ± 1915.24 mmol/L vs 1034.20 ± 915.32 mmol/L, p < 0.001).

CONCLUSIONS

The prevalence of OP following assisted reproductive technology is on the rise. History of abdominal surgery may be a high risk factor for OP patients who have the tendency of high β-hCG levels. The ultrasonic preoperative diagnosis is conductive to the early diagnosis of OP though the diagnosis accuracy is low.
