Correlação entre o achado ultra-sonográfico isolado de cisto de cordão umbilical e anomalias fetais

Abstract

OBJECTIVE: To correlate the isolated sonographic finding of umbilical cord cyst with fetal anomalies such as chromosomopathies and structural changes. According to the medical literature, the clinical implications of the sonographic finding of umbilical cord cyst in the second and third trimesters of pregnancy are well established; however, the meaning of this finding in the first trimester still remains controversial. MATERIALS AND METHODS: A retrospective study was developed with consecutive, pregnant women with single living fetuses presenting with umbilical cord cyst as an isolated finding, over a 10-year period (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006). Ultrasound studies were performed in all cases for screening of fetal anomalies after the diagnosis of umbilical cord cyst. Neonates and umbilical cords were evaluated after delivery for the presence of abnormalities. RESULTS: Nine cases presenting umbilical cord cyst as a sole finding with no other sonographic marker for fetal abnormality were evaluated. Two cases were detected in the first pregnancy trimester and seven cases in the second and third trimesters. Fetal cytogenetic study was done by means of amniocentesis in two cases. No newborn presented with structural anomalies or aneuploidy. CONCLUSION: Isolated sonographic finding of umbilical cord cyst did not imply increased risk for fetal structural anomalies or aneuploidies.

“…11,14 Isolated UC cysts, as seen in this case, are considered to have a favorable fetal outcome. Kobayashi et al, 15 in their study, evaluated nine fetuses who presented with isolated UC cysts at birth and all of them had an uneventful birth and normal development. Similarly, Zangen et al 4 reported isolated UC cysts with an uneventful fetal outcome in 7 of the 10 cases evaluated by them.…”
