PURPOSE The purpose of this study was to determine the outcomes among three different surgical approaches for performing an aortopexy to treat severe tracheomalacia (STM). METHODS A retrospective review was performed for all patients who underwent an aortopexy by pediatric surgeons at a single institution during 1997-2012. Data collected included details(More)
Congenital cystic adenomatoid malformation (CCAM), intralobar sequestration (ILS), extralobar sequestration (ELS), and lobar emphysema (LE) are well-accepted entities; however, certain findings are common to all, particularly the parenchymal maldevelopment characterizing CCAM. Isolated reports have described bronchial atresia (BA) in some specimens in all 4(More)
Animal studies demonstrate that the fetus heals cutaneous wounds by reformation of normal tissue architecture without scar formation. We have developed a new model to study human fetal skin wound healing. Grafts of human fetal skin placed onto athymic mice retain the morphologic features of normal development, although they differentiate at an accelerated(More)
Fetal wound healing is fundamentally different from wound healing in the adult. Although experimental work in mice, rats, rabbits, monkeys, and sheep has demonstrated that fetal healing occurs without inflammation and scarring, all of these studies have been limited to fetal skin wounds. Whether all fetal tissues heal in a regenerative-like fashion is(More)
BACKGROUND/PURPOSE Congenital diaphragmatic hernia (CDH) is a condition associated with significant mortality. This study examines the survival rate of neonates with CDH treated by a multidisciplinary team in a single pediatric hospital. Actual survival rate is compared with predicted outcome based on severity of illness. METHODS A consecutive series of(More)
BACKGROUND/PURPOSE Vascular anomalies are diagnosed prenatally with increasing frequency. The authors reviewed a group of children treated at their center who had an abnormal prenatal diagnosis to determine (1) fetal age at which the vascular anomaly was detected, (2) general diagnostic accuracy, and (3) impact on ante- and postnatal care. Their findings(More)
Despite advances in postnatal care, patients born with a congenital diaphragmatic hernia (CDH) suffer substantial morbidity and mortality. The present study was undertaken to determine the prognostic influence of prenatally-diagnosed liver herniation in the hemithorax in fetuses with CDH. The medical records of 48 patients evaluated for a(More)
Clinical observations and experimental data suggest that fetal wound healing is very different from adult wound healing. An understanding of the biology of scarless fetal wound healing has tremendous clinical potential for modulating postnatal wound problems. In this study, the fetal lamb model was used to assess excisional fetal skin wound contraction in(More)
BACKGROUND Accurate prenatal prediction of outcome for fetuses who have congenital diaphragmatic hernia (CDH) is very difficult. The authors previously reported a retrospective analysis of risk factors for fetal CDH and proposed a new index of severity: the lung-to-head ratio (LHR). The authors now report a prospective study to test whether this new index(More)
PURPOSE This study was aimed at determining whether fetal tissue constructs can be engineered from cells normally found in the amniotic fluid. METHODS A subpopulation of morphologically distinct cells was isolated mechanically from the amniotic fluid of pregnant ewes (n = 5) and expanded selectively. Its lineage was determined by immunofluorescent(More)
