[Fetal digestive tract imaging].

The exploration of the fetal digestive tract is not systematized and the ends (thoracic oesophagus and anorectal area) are often excluded from the examination excluded from screening. Only the foetal digestive pathology of liquid expression (digestive obstruction, digestive duplication) is easily detected. The most frequent digestive pathologies (oesophagus atresia, anorectal malformation) are still very often a neonatal discovery.

Prenatal diagnosis of mosaicism for 11q terminal deletion.

The phenotype of 11q terminal deletion also known as Jacobsen syndrome is a clinically well known entity whose diagnosis in infancy and childhood is based on clinical examination, hematological and cytogenetic findings. Hematological features in Jacobsen syndrome are very similar to those reported in Paris-Trousseau syndrome (PTS) which is also associated with11q terminal deletion. Karyotype analysis shows a variable terminal deletion from 11q23 sub-band extending to the telomere.

Colonic triplication associated with anorectal malformation: case presentation of a rare embryological disorder.

Tubular colonic triplication is an extremely rare hindgut malformation, with only 2 reports in the literature to date. The present authors describe the new and unusual case of a boy born with an imperforate anus, rectovesical fistula, and 3 distinct left colons. The bladder was divided by an incomplete septum.

Prenatal diagnosis of umbilicoportosystemic shunts: report of 11 cases and review of the literature.

Objective: The objective of our study was to classify, understand, and illustrate abnormalities of the embryologic development of the umbilical vein and the portal system resulting in umbilicoportosystemic shunts. According to our data and a review of the literature, we propose an anatomic, biometric, and hemodynamic assessment of umbilicoportosystemic shunts.

Conclusion: Umbilicoportosystemic shunts encompass different congenital vascular abnormalities that should be recognized because they may interfere with fetal growth and circulation.

Inhaled nitric oxide improves oxygenation in very premature infants with low pulmonary blood flow.

Aim: Inhaled nitric oxide (iNO) is used to reduce right-to-left extrapulmonary shunting by decreasing pulmonary vascular resistance in term or near-term infants. The objectives of this study were to determine, first, the pulmonary blood flow status of very preterm infants with hypoxaemic respiratory failure, then the response of oxygenation to iNO therapy according to pulmonary blood flow (PBF) and, finally, to verify the lack of adverse side effects of iNO on the ductus arteriosus.

Methods: Infants below 32 wk gestational age (GA) with hypoxic respiratory failure and aAO2 < 0.
