Perinatal outcome after prenatal diagnosis of placental chorioangioma.

Objective: To review the prenatal complications, management, and perinatal outcome in pregnancies complicated by placental chorioangioma.

Methods: Cases of placental chorioangioma diagnosed prenatally as part of a prospective, multicentric program for fetal diagnosis and therapy were identified. All cases were evaluated with color flow imaging.

Second-trimester sonographic findings in trisomy 22: report of 3 cases and review of the literature.

Objective: To describe cases of trisomy 22 detected prenatally on second-trimester sonography and to review the literature on similar cases, with special emphasis on the prenatal findings and pregnancy outcome.

Methods: We performed follow-up second-trimester sonography and fetal karyotyping on 3 pregnant women who were referred because of abnormal findings on initial second-trimester scans. We also conducted a literature search for other reports of sonographic findings in trisomy 22.

Prenatal detection of velamentous insertion of the umbilical cord: a prospective color Doppler ultrasound study.

Objective: Velamentous insertion of the umbilical cord, with a reported incidence of 1% in singleton pregnancies, has been associated with several obstetric complications including fetal growth restriction, prematurity, congenital anomalies, low Apgar scores, fetal bleeding and retained placenta. The aim of this study was to determine the feasibility of identifying velamentous insertion of the umbilical cord during routine obstetric ultrasound.

Design: This was a prospective, cross-sectional ultrasound study in 832 unselected second- and third-trimester singleton pregnancies.

Risks of funipuncture in fetuses with single umbilical arteries.

Objective: To estimate procedure-related risks of funipuncture in fetuses with single umbilical arteries (UAs).

Methods: We identified fetuses that had blood samples collected by funipuncture and in which single UAs were detected, prenatally or postnatally. We also recorded maternal demographics, prenatal sonographic findings, gestational age at the time of the procedure, procedure-related complications, and perinatal outcomes.

Pseudocyst of the umbilical cord: prenatal sonographic appearance and clinical significance.

Objective: To assess the clinical significance of umbilical cord pseudocysts detected prenatally by sonography.

Methods: The prenatal sonographic findings, karyotype, and perinatal outcome in 13 fetuses with umbilical cord pseudocysts were reviewed retrospectively.

Results: Umbilical cord pseudocysts were diagnosed at a median gestation of 27 weeks (range 15-37).
