Aim: Congenital diaphragmatic hernia (CDH) is a rare disease (1/3000 live births). Carriers display a diaphragmatic defect responsible for an impaired pulmonary development and physiology. The aim of this study was to evaluate the information given to couples whose fetus display a CDH and the current knowledge of French sonographers about this disease.
Materials and methods: A questionnaire was sent by email to 2000 sonographers, members of the French college of fetal ultrasonography, between May 1st and December 31st of 2010.
Results: 20,7 % (414) of the sonographers answered. Twenty-four percent are second line sonographers. Thirty-eight percent did not diagnose any diaphragmatic hernia in the last five years (2005-2010) and 42 % diagnosed 1 or 2 during the same period. Information concerning the prognostic remains elusive and most sonographers rapidly referred patients to prenatal diagnostic centers. Fifty-nine percent of sonographer are not aware of the existence in France of a Centre for Rare Disease for CDH.
Conclusion: Accurate assessment of prognosis is essential to provide adequate information to couples and to help them make a decision on whether or not to perform an in utero treatment. The heterogenous results of the survey clearly show the disparities between sonographers on the type of information delivered. A better diffusion of prognostic evaluation in CDH, among sonographers is needed.
