Malformations and deformations in abdominal pregnancy

Abstract

Abdominal gestation is a relatively uncommon complication of pregnancy. Previous reports describe a high incidence of fetal deformations and mortality as well as maternal mortality. A case of twin abdominal gestation is presented and the literature concerning abdominal pregnancy since 1809 is reviewed. The survival rate of liveborn infants of 30 or more weeks gestation was 63%. The maternal mortality rate since 1809 was 18.2%, but this has decreased to 4.5% during the last 20 years. The combined rate of malformations and deformations in the infants was 21.4%. The most common deformations observed were facial and/or cranial asymmetry and various joint abnormalities. Among the most common malformations were limb deficiency and central nervous system malformations. Proposed mechanisms of compression and vascular disruption are discussed.

A 34-week ovarian pregnancy: case report and review of the literature

“…Pulmonary hypoplasia, pressure deformities, and foetal growth restriction due to placental insufficiency are the most eminent causes leading to neonatal complications. Typical deformities include limb defects, facial and cranial asymmetry, joint abnormalities and central nervous malformation (28). These pregnancies usually do not extend to 37 weeks and usually end up with foetal loss (29).…”

Secondary Abdominal Pregnancy – A Case Report

“…There are reports of foetal malformations as high as 40% associated with abdominal pregnancies and only 50% of these babies survive up to one week post delivery. 8,9 In his extensive review, Stevens found some varying degrees of deformations and malformations in 21.4% of these infants 10 . In this case that has been presented; no malformation has been found on the child.…”

Advanced abdominal pregnancy with a healthy newborn: a rare case report

“…The most frequent and reliable finding includes an empty uterus seen separate from the fetus. 14,15 Other signs include an ectopic intra-abdominal placenta, pseudo placenta praevia appearance, oligohydramnios, lack of myometrial tissue around fetus, fetus and placenta obscured by overlying bowel gas and abnormal fetal presentation.…”
