title: [Congenital malformations of the inferior vena cava. Embryological, anatomical and radiological study (author's transl)].
abstract: Congenital malformations of the inferior vena cava are characterized by their diversity which is related to the complexity of the embryological development of this vessel. The authors review the embryogenesis and origin of the different segments of the inferior vena cava and describe the various types of malformation, including the causative embryological abnormality, ther frequency, possible clinical repercussions, and radiological aspects. Phlebocavography is essential for the identification of the various types of abnormality. Five different types of malformation are reported. Three of these are relatively rare (left inferior vena vaca, congenital membrane of the inferior vena cava, absence of the hepatic segment with continuation of the isolated azygos segment).
