[Anomalies of the inferior vena cava (author's transl)].

After a detailed account of the developmental anatomy of the inferior vena cava, which arises from various segments, an attempt is made at a systematic classification of anomalies of the inferior vena cava. For this purpose, the angiographic appearances and available literature have been considered. The following anomalies have been distinguished: 1. left-sided position, 2. duplication, 3. anomalous insertion into the left atrium, 4. agenesis and 5. stenosis and occlusion.
