[Prenatal diagnosis and management in VACTERL association]

In terms of the VACTERL-Association we are dealing with a non-random association of malformations following a defect during mesodermal development of embryogenesis due to a variety of causes. We report on three cases with VACTERL-type malformations diagnosed by prenatal ultrasound presenting cardial defects, renal abnormalities, single umbilical arteries and esophageal stenosis. We present sonographical, clinical and autopsy findings and discuss the pathogenesis of VACTERL-Association as a defect of mesenchymal development in early embryogenesis.
