简要总结
The purpose of this study is to investigate the ultrasound characteristics and outcome of pregnancies with fetal Intra-abdominal umbilical vein aneurysm.
详细描述
Intra-abdominal umbilical vein aneurysm is a rare pathology of the fetal venous system. Its incidence is low, evaluated between 0.4 and 1.1 / 1000.
Intra-abdominal umbilical vein aneurysm is identified as an oval or rounded, anechoic mass located between the abdominal wall and the lower edge of the liver.
It is defined by two criteria: either a diameter greater than 9 mm or a diameter of the subhepatic segment of the umbilical vein greater than 50% of the diameter of its intrahepatic segment.
The complications that can occur during pregnancy are mainly represented by the MFIU, the occurrence of thrombosis and intrauterine growth retardation (IUGR). Their overall frequency is evaluated at 10%.
A complete fetal morphological assessment is necessary to eliminate the presence of other lesions. However, ultrasound monitoring is recommended during the third trimester in search of an increase in dilation and especially the appearance of a thrombus. A particular clinical form, related to abnormal umbilical vein involvement in the infra-hepatic portal system, must be individualized because of a high risk of thrombosis. It justifies the realization of an abdominal ultrasound in the first days of life

结局指标
主要结局
Vital status at birth.
时间窗: Through study completion, an average of 2 years.
From birth, it is necessary to evaluate the state of the child. This evaluation is done by the APGAR coefficient. The following actions are systematically performed: place the child on a heating table, aspire mouth, pharynx, nostrils. Specify rapidly, heart and respiratory rhythms, quality of cry, baby's color and responses to skin stimulation. These five criteria rated from zero to two make it possible to determine the Apgar score: it is practiced at one, three, five and ten minutes of life. This assessment helps to guide the behavior of the newborn: if the score is greater than eight to one minute, it means that the newborn has a good adaptation to the ectopic life. If it is less than three to one minute, the newborn is in a state of apparent death involving emergency resuscitation. An intermediate figure, witnessing hypoxia-anoxia, justifies management adapted.
次要结局
- Collection of congenital anomalies and pregnancy Pathologies.(From the inclusion of the patient until the end of pregnancy.)
- Characteristics of the umbilical vein aneurysm.(From the inclusion of the patient until the end of pregnancy.)
