A Case of Annular Pancreas and Endocardial Cushion in the Abscence of Down Syndrome

ABSTRACT

Annular pancreas is a rarely found gastrointestinal tract malformation, and is frequently associated with Down syndrome. Endocardial cushion defect is a type of congenital heart disease, commonly also related to Down syndrome. However, a combination of endocardial cushion defect with annular pancreas has not been reported previously. We recently experienced such a case in 2 month old boy. Moreover Down syndrome was excluded through physical examination and a chromosomal study. We think it difficult to obtain a complete explanation for this condition through the currently known pathogenesis of annular pancreas and endocardial cushion defect.
