abdominal pregnancy is more complicated. Advanced abdominal pregnancy Advanced abdominal pregnancy refers to situations where the pregnancy continues past 20 weeks of gestation (versus early abdominal pregnancy < 20 weeks). In those situations, live births have been reported in the lay press where the babies are not uncommonly referred to as 'Miracle babies'. A patient may carry a dead fetus but will not go into labor. Over time, the fetus calcifies and becomes a lithopedion. It is generally recommended to perform a laparotomy when the diagnosis of an abdominal pregnancy is made. However, if the baby is alive and medical support systems are in place, careful watching could be considered to bring the baby to viability. Women with an abdominal pregnancy will not go into labor. Delivery in a case of an advanced abdominal pregnancy will have to be via laparotomy. The survival of the baby is reduced and high perinatal mortality rates between 40% and 95% have been reported. Babies of abdominal pregnancies are prone to birth defects due to compression in the absence of the uterine wall and the often reduced amount of amniotic fluid surrounding the unborn baby. The rate of malformations and deformations is estimated to be about 21%; typical deformations are facial and cranial asymmetries and joint abnormalities and the most common malformations are limb defects and central nervous malformations. Once the baby has been delivered placental management becomes an issue. In normal deliveries the contraction of uterus provides a powerful mechanism to control blood loss, however, in an abdominal pregnancy the placenta is located over tissue that cannot contract and attempts of its removal may lead to life-threatening blood loss. Thus blood transfusion is frequent in the management of patients with this kind of pregnancy, with others even using tranexamic acid and recombinant factor VIIa, which both minimize blood loss. Generally, unless the placenta can be easily tied off or removed, it may be preferable to leave it in place and allow for a natural regression. This process may take several months and can be monitored by clinical examination, checking human chorionic gonadotropin levels and by ultrasound scanning (in particular using doppler ultrasonography. Use of methotrexate to accelerate placental regression is controversial as the large amount of necrotic tissue is a potential site for infection, mifepristone has also be used to promote placental regression. Placental vessels have also been blocked by angiographic embolization. Complications
