[V.A.T.E.R. association and its limits].

Comparative investigation of 92 cases of V.A.T.E.R. syndrome (4 personal cases) and 62 cases of caudal regression (Duhamel syndrome) (2 personal cases) are performed. There is much analogy between these two entities. Initial impairment would be an early dysfunction of mesoderm setting up located on esophagus in V.A.T.E.R. syndrome and on kidneys in Duhamel syndrome. Etiopathogenic factors remain unknown. Genetic counseling is good. Detection of only one mesodermal malformation leads to inquire other unnoticed anomalies (kidneys, heart, spine, alimentary duct).
