Double inferior vena cava

Overview

Type of disease: Congenital onset | Rare conditions

Double inferior vena cava is a vein abnormality that is present from birth (congenital). Individuals with this anomaly have two inferior vena cavas instead of one. The inferior vena cava carries oxygen-poor blood from the lower parts of the body into the heart. Double inferior vena cava does not cause any symptoms. It is usually diagnosed when an imaging test, such as CT or MRI, is performed for other medical reasons. The reported incidence of double inferior vena cava ranges from 0.2 percent to 3 percent. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
