Viable abdominal pregnancy: a case report in Yaoundé (Cameroon)

Hemoperitoneum during removal of the placenta in advanced abdominal pregnancy with live fetus delivered at 37 weeks of gestation. A case report in a low-resource setting and literature review

INTRODUCTION AND IMPORTANCE

Advanced abdominal pregnancy (> 20 weeks gestation) is a rare condition life-threatening for mother and fetus.

CASE PRESENTATION

A 31-years-old African woman presented from a rural district to Mutoyi Hospital for first gynecological evaluation after 37 weeks of amenorrhea, abdominal pain and vaginal bleeding. An ultrasound revealed an extra-uterine fetus. Laparotomy was done and a live fetus weighing 1980 g was delivered. Removal of the placenta, triggered massive bleeding (5000 mL) with shock. After re-laparotomy for post-operative ileus and hemoperitoneum, the mother and infant were discharged in good health.

CLINICAL DISCUSSION

Viable fetus can be delivered after an advanced abdominal pregnancy. Removal of the placenta is controversial. We review currently medical literature on advanced abdominal pregnancy and propose a management of the placenta in these patients.

CONCLUSION

We recommended to leave the placenta in situ, to avoid intraoperative bleeding. Placenta involution during follow-up can be revealed by ultrasound, colordoppler and β-hCG serum level decrease.

Abdominal Pregnancy: A Case Report of a Viable Nondysmorphic Fetus

Abdominal pregnancy is a rare form of ectopic gestation. It accounts for about 0.4% of all cases of ectopic pregnancy, and often associated with significant morbidity and mortality. Clinical presentation varies, and diagnosis is commonly challenging. Although ultrasound is helpful in early gestation, this could be unsatisfactory at advanced gestational age. Hence, a high index of suspicion is required in the diagnosis. We present a case of secondary abdominal pregnancy in a 27-year-old gravida 2 para 0 + 1 at an estimated gestational age of 33 weeks and 5 days. She had ultrasound scan done at 9 weeks and 2 days confirming the diagnosis, but declined surgery to seek spiritual intervention. She subsequently presented with generalized abdominal pain and fainting attack. She had exploratory laparotomy with delivery of a live female baby with no congenital anomaly. The placenta was attached to the left infundibulopelvic ligament and was delivered wholly without remnants. She was discharged on the 8^th postoperative day, and the baby was discharged after 14 days from the neonatal intensive care unit. Accurate diagnosis and prompt intervention with evaluation of placenta attachment is vital to prevent adverse consequences.

Term Abdominal Pregnancy Revealed by Amnioperitoneum in Rural Area

Abdominal pregnancy (AP) accounts for 1% of ectopic implantations. In sub-Saharan Africa, the high prevalence of sexually transmitted infections explains the increasing frequency of this pathology. In Cameroon it rose from 1/10000 deliveries (1995) to 3.3/10000 (2015). Authors herein report a case of a viable abdominal pregnancy discovered at term during emergency laparotomy for suspected uterine rupture. The 24-year-old G2P0 patient was HIV-positive, under antiretrovirals, though AP exceptionally occurs in HIV patients. She did only two antenatal consultations: her main complaint was abdominal pain but five echographies concluded to normal intrauterine pregnancy. Findings at laparotomy were as follows: amnioperitoneum, a live female baby weighing 3.4 kilogrammes without deformities and a placenta deeply inserted on the uterine fundus. Removal of the placenta triggered massive bleeding (2400 milliliters) with shock managed with a tourniquet on the lower uterine segment and fluid resuscitation. Outcome was favourable for the mother and child. Prevention of vertical transmission of HIV was successful with antiretroviral therapy.

Conservative Management and Planned Surgery for Periviable Advanced Extrauterine Abdominal Pregnancy with Favorable Outcome: Report of Two Cases

Advanced abdominal pregnancy is an extremely rare condition that poses diagnostic and management challenges. A high index of suspicion and careful assessment of the patient's symptoms, supplemented with obstetric ultrasound, and magnetic resonance imaging, are crucial for timely diagnosis and management to prevent life-threatening complications. The presence of periviable fetuses in advanced abdominal pregnancies increases the challenge to achieve a balance between maternal and fetal benefits and risks. Early diagnosis and management decisions via a multidisciplinary approach and planned delivery are of paramount importance to minimize complications and achieve favorable maternal and fetal outcomes. Even in the setting of oligohydramnios and suspected preterm premature rupture of membranes, in-patient conservative management and an individualized planned surgical approach that includes removing or leaving the placenta in place are appropriate for managing the periviable abdominal pregnancy.
