OBJECTIVE Our purpose was to review our experience with fetal congenital cystic adenomatoid malformation and extralobar pulmonary sequestration emphasizing natural history, management, and outcome. STUDY DESIGN We conducted a retrospective review of 175 fetal lung lesions diagnosed by antenatal ultrasonography at 2 fetal treatment centers. RESULTS There(More)
Pre-clinical studies in mice and haemophilic dogs have shown that introduction of an adeno-associated viral (AAV) vector encoding blood coagulation factor IX (FIX) into skeletal muscle results in sustained expression of F.IX at levels sufficient to correct the haemophilic phenotype. On the basis of these data and additional pre-clinical studies(More)
BACKGROUND/PURPOSE Cystic adenomatoid malformation of the lung (CAM) diagnosed in utero has a variable natural history that may result in hydrops in up to 40% or regress in up to 15%. No criteria have been available to determine which lesions would grow and develop hydrops versus those whose growth would stabilize or regress. To better understand the(More)
The field of stem cell biology continues to evolve with the ongoing characterization of multiple types of stem cells with their inherent potential for experimental and clinical application. Mesenchymal stem cells (MSC) are one of the most promising stem cell types due to their availability and the relatively simple requirements for in vitro expansion and(More)
Hemophilia B is an X-linked coagulopathy caused by absence of functional coagulation factor IX (F.IX). Previously, we established an experimental basis for gene transfer as a method of treating the disease in mice and hemophilic dogs through intramuscular injection of a recombinant adeno-associated viral (rAAV) vector expressing F.IX. In this study we(More)
BACKGROUND Indications for the ex utero intrapartum therapy (EXIT) procedure have expanded to include any fetal anomaly in which resuscitation of the neonate may be compromised. METHODS We reviewed the medical records of 9 patients after resection of lung lesions during the EXIT procedure. RESULTS The mean gestational age at EXIT procedure was 35.4(More)
In animal experiments, it has been shown that tracheal occlusion counteracts the pulmonary hypoplasia associated with congenital diaphragmatic hernia (CDH). Successful clinical implementation requires a reliable, reversible, and atraumatic technique of occluding the fetal trachea. With this clinical goal in mind, the authors evaluated the following three(More)
CONTEXT Hindbrain herniation occurs in a large percentage of children with myelomeningocele and is the leading cause of death in this population. The effect of early fetal closure of myelomeningocele on hindbrain herniation is unknown. OBJECTIVE To determine whether early fetal closure of myelomeningocele affects hindbrain herniation. DESIGN Case series(More)
Congenital high airway obstruction syndrome (CHAOS) is a rare disorder defined as any fetal abnormality that obstructs the larynx or trachea. Prompt airway intervention at delivery after accurate prenatal diagnosis may allow survival of this otherwise fatal condition. To identify prenatal MRI findings in CHAOS, to compare these findings with those of fetal(More)
