Amniopatch for iatrogenic rupture of the fetal membranes

With the increased use of invasive fetal procedures, the number of women facing post-procedure membrane rupture is increasing. Here we review the use of platelets and fresh frozen plasma for sealing iatrogenic fetal membrane defects by describing the mechanisms of action of the amniopatch procedure as well as published experience. In cases of iatrogenic preterm pre-labour rupture of the membranes, amniopatch effectively seals the fetal membranes in over two-thirds of cases. There is a risk of 16% of in utero fetal death, which may occur at varying intervals from the procedure and often for unknown reasons. Amniopatch has also been used as a treatment of chorionic membrane separation. In summary, current experience suggests that in cases of early onset but persistent amniotic fluid leakage following an invasive fetal procedure, amniopatch is an option.

Isolated fetal hydrothorax with hydrops: a systematic review of prenatal treatment options

Objective To evaluate the effect of prenatal therapeutic interventions on perinatal outcome in pregnancies complicated by isolated fetal hydrothorax with hydrops. Methods A systematic review of the literature from January 1982 to January 2006 of perinatal outcome in pregnancies with isolated fetal hydrothorax with hydrops with any form of prenatal treatment was conducted. Results Forty-four articles met our selection criteria, reporting a total of 172 fetuses treated prenatally. Reported treatment options were single (n = 13) or serial thoracocentesis (n = 18), thoraco-amniotic shunt placement (n = 100) or a combination of thoracocentesis and shunting (n = 36). Four case-reports described pleurodesis with OK-432, (n = 3) and intrapleural injection of autologous blood (n = 2). Overall survival rate was 63%, ranging from 54% for single thoracocentesis to 80% in the 5 cases treated with pleurodesis, without statistically significant differences between the treatment modalities. Shunt-placement with or without prior thoracocentesis was most often described, with survival rates of 67 and 61% respectively. Discussion The available literature consists exclusively of case reports and case series. This systematic review suggests that with prenatal intervention, perinatal survival rates around 63% are possible. There is a need for prospective, adequately controlled studies with long-term follow-up to determine the best treatment and more reliable outcome data in pregnancies complicated by fetal hydrothorax with hydrops.

Postnatal management and outcome for fetal-diagnosed intra-cerebral cystic masses and tumours

The increasing availability and resolution of non-invasive prenatal imaging has increased our ability to diagnose accurately a wide variety of fetal anomalies. It has also resulted in the serendipitous discovery of ‘lesions’ that may have little clinical impact upon the child's subsequent development although their ability to raise parental anxiety can be great. The purpose of this review is to put the postnatal clinical relevance of some of these findings into their proper context. Copyright © 2009 John Wiley & Sons, Ltd.
