CASE-REPORT - INTERRUPTION OF THE INFERIOR VENA-CAVA WITH ANOMALOUS INTRAHEPATIC CONTINUATION

Infrahepatic interruption of the inferior vena cava (IVC) with azygos and hemiazygos substitution is a rare IVC anomaly which has been documented in the literature (Anderson et al, 1961; Chuang et al, 1974; Floyd & Nelson, 1976; Mayo et al, 1983). Recently Bercoff et al and Ghossain et al reported two cases with portal continuation of the interrupted IVC (Bercoff et al, 1985; Ghossain et al, 1988). In our case, we describe a left sided IVC with infrahepatic interruption which continues by both the azygos system and the hepatic veins via anomalous intrahepatic vessels. To our knowledge such a continuation with intrahepatic anomalous vessels has not been described before.
