Hc. Alhan et al., ABSENT RIGHT SUPERIOR VENA-CAVA WITH HYPOPLASTIC PROXIMAL INFERIOR VENA-CAVA, The Annals of thoracic surgery, 62(2), 1996, pp. 566-568
We describe the precise preoperative diagnosis of a very rare anomaly
that comprises absence of the right superior vena cava, persistence of
the left superior vena cava, and proximal hypoplasia of the inferior
vena cava draining into the left superior vena cava via the hemiazygos
vein associated with a large atrial septal defect and tricuspid regur
gitation.
