title: Portohepatic shunt in a Down syndrome patient with an interchange trisomy 47,XY,-2,+der(2),+der(21)t(2;21)(p13;q22.1)mat.
abstract: A rare vascular portohepatic anomaly was identified in a Down syndrome patient with a 47,XY,-2,+der(2),+der(21)t(2;21)(p13;q22.1) mat chromosomal complement. This vascular defect involves a direct communication between the right portal vein and the inferior vena cava (IVC). We discuss the possibility that this vascular defect is a rare manifestation in Down syndrome. Alternatively, the existence of these 2 rare events in the same patient raises the possibility that they are causally related.
