Ectopic Pregnancy in caesarean section scar: A case report

Caesarean scar ectopic pregnancy: A case series

Caesarean scar ectopic pregnancy (CSEP) is a uncommon presentation of pregnancy with incidence of nearly 1 in 2000 pregnancies. We present this case series of scar pregnancy with a objective to help obstetricians in early diagnosis and appropriate management to prevent its catastrophic complications.

Extravillous trophoblast invasion and decidualization in cesarean scar pregnancies

INTRODUCTION

The increasing cesarean section rate has led to an increase in the number of subsequent pregnancies resulting in a cesarean scar pregnancy. There appears to be preferential attachment of the blastocyst to the scar site, which may be associated with defective decidua in that region, resulting in abnormal implantation, which can in turn negatively affect the success of the pregnancy. The aim of the current study was to evaluate the extravillous trophoblast, decidua, and myometrium in scar and adjacent non-scar regions of the implantation site of a cesarean scar pregnancy.

MATERIAL AND METHODS

Samples containing a gestational mass were obtained by laparoscopic excision from patients with a cesarean scar pregnancy at 6-11 weeks of gestation as diagnosed by transvaginal or transabdominal ultrasound (n = 8 type II cesarean scar pregnancy). Cesarean scar pregnancy tissues were separated into scar and non-scar regions, and the scar regions were sub-separated into non-implantation and implantation sites. Serial sections were histologically examined after hematoxylin and eosin, Masson's trichrome and immunochemical staining, and changes in the myometrium, extravillous trophoblast, and decidua were evaluated.

RESULTS

In cesarean scar pregnancy, compared with scars not in the implantation site, scars in the implantation site displayed increased fibrosis, and had disrupted myometrium, which was related to varying patterns of E-cadherin expression as a response to extravillous trophoblast invasion. In addition, local decidua was found at the non-scar implantation sites, with multinucleated trophoblast giant cell accumulation and shallow invasion. These features were not evident in the scar implantation sites.

CONCLUSIONS

This study emphasizes that the decidua drives multinucleated trophoblast giant cell differentiation, limiting the degree of invasion. Better characterization of this differentiation process may be helpful for better management and avoidance of the consequences of cesarean scar pregnancy.

Cesarean scar ectopic pregnancy: A cause of failed first trimester surgical termination of pregnancy (case report)

Cesarean scar (ectopic) pregnancy is due to blastocyst implantation on a Caesarean scar. The current case presented by vaginal bleeding after a failed surgical termination of pregnancy. The ultrasound scan revealed a cesarean scar ectopic pregnancy managed by surgical removal. The possibility of cesarean scar ectopic pregnancy should be considered in any case presenting with a low-lying gestational sac.

Cesarean Scar Ectopic Pregnancy: Diagnosis With Ultrasound

We present a rare case of cesarean scar ectopic pregnancy as diagnosed by transvaginal ultrasonography. Cases such as this are rare, but they are becoming more commonly detected with the growing frequency of cesarean sections, improving technology, and provider proficiency with point-of-care ultrasound. Quick identification of this dangerous diagnosis can be life saving for the patient, as the outcomes of ruptured cesarean ectopic pregnancy may include significant hemorrhage, uterine rupture, and possibly maternal death.

Ruptured caesarean scar ectopic pregnancy: a diagnostic dilemma in a resource-limited setting

BACKGROUND

Caesarean scar pregnancy (CSP) remains a very rare form of ectopic pregnancy associated with serious life threatening obstetric complications and even death in case of late diagnosis and treatment.

CASE PRESENTATION

We report a case of a ruptured caesarean scar pregnancy in a 29 year-old gravida 5, para 3 with a past obstetric history of two consecutive caesarean sections done 9 and 5 years ago respectively. The patient presented with intermittent lower abdominal pains on a 20 weeks gestation associated with mild epigastralgia and 2 previous episodes of mild pervaginal bleeding (2 and 1 months ago respectively before consultation) managed with injectable progesterone. Her evolution 4 h later was marked by an increase in the intensity of the abdominal pain, an unmeasurable blood pressure and a feeble pulse. Immediate paracentesis revealed 10 cc of fresh non coagulating blood. The diagnosis of ruptured ectopic pregnancy with abundant hemoperitoneum was considered and an emergency laparotomy with fluid and blood resuscitation was carried out. A midline laparotomy revealed a ruptured caesarean scar ectopic pregnancy with an abundant hemoperitoneum. Careful resection of the placenta and repair of the ruptured isthmic region of the uterus was carried out. Recovery after surgery was without complications and the patient was discharged on the 6th day following surgery.

CONCLUSION

Caesarean scar pregnancy remains a very rare obstetric condition. Late diagnosis of this condition can be associated with serious life threatening obstetric complications. The rarity of the condition warrants a high index of suspicion among clinicians.

A Rare Case Report of Caesarean Scar Ectopic Pregnancy

Caesarean scar ectopic is one of the rarest of all ectopic pregnancies. It is defined as when a blastocyst implants on a previous Caesarean scar. The incidence of Caesarean scar ectopic has increased due to increase in number of Caesarean deliveries. Early diagnosis of this can be done by using sonography. It is very important because a delay can lead to increased maternal morbidity and mortality. Early diagnosis leads to prompt management and improves the outcome by allowing preservation of future fertility. Magnetic Resonance Imaging (MRI) has important role when sonography is equivocal or inconclusive before therapy or intervention. We are reporting a rare case of G3P2l2 with previous two Caesarean deliveries, diagnosed as Caesarean scar ectopic pregnancy with the help of sonography and MRI. Patient underwent laparotomy and on histopathological examination Caesarean scar pregnancy was confirmed.
