Prenatally diagnosed giant omphaloceles: short‐ and long‐term outcomes

TL;DR: To review prenatal findings, short‐ and long‐term outcomes of giant omphaloceles (GO) managed at a single institution (1996–2001) are reviewed.
Journal ArticleDOI

Congenital high airway obstruction syndrome: MR/US findings, effect on management, and outcome.

TL;DR: MRI demonstrates large lung volumes, increased lung signal intensity, inverted diaphragm, and dilated fluid-filled lower airway, and usually identifies the obstruction level, but CHAOS is frequently misdiagnosed on screening US.
Journal ArticleDOI

Use of magnetic resonance imaging in prenatal prognosis of the fetus with isolated left congenital diaphragmatic hernia

TL;DR: To investigate the prognostic value of magnetic resonance‐calculated fetal lung volumes (FLV) in fetuses with isolated left congenital diaphragmatic hernia who receive standardized prenatal and postnatal care at a single institution, magnetic resonance-calculated lung volumes are used.
Journal ArticleDOI

Ex utero intrapartum treatment in the management of giant cervical teratomas

TL;DR: The EXIT procedure continues to be the optimal delivery strategy for patients with prenatally diagnosed giant cervical teratomas and potential airway obstruction at birth and a thorough evaluation of the prenatal images and an experienced multidisciplinary team are key factors for an effective approach to the obstructed fetal airway.
Journal ArticleDOI

Comparison of ultrasound and magnetic resonance imaging parameters in predicting survival in isolated left-sided congenital diaphragmatic hernia.

TL;DR: To compare test characteristics of ultrasound‐ and magnetic resonance imaging (MRI)‐derived parameters in predicting newborn survival in cases of isolated left‐sided congenital diaphragmatic hernia, an attempt is made to evaluate the relationship between ultrasound and MRI values and newborn survival.
