Report of two cases of double inferior vena cava with an emphasis on embryogenesis and clinical relevance

Author(s): Marjeta Tanka*

Double inferior vena cava is a congenital variation caused by an unusual embryological development of the inferior vena cava. Most malformations of inferior vena cava are accidental findings in abdomen imaging. We report two cases with double inferior vena cava diagnosed during routine computed tomography in two patients referred to our clinic for abdominal pain. In both cases the double inferior vena cava was considered to be a persistence of both the right and left supracardinal veins. Although this variation is not common it becomes significant when planning surgical and radiological vascular procedures.
