INTERRUPTED INFERIOR VENA-CAVA IN ASPLENIA SYNDROME AND A REVIEW OF THE HEREDITARY PATTERNS OF VISCERAL SITUS ABNORMALITIES

We present the clinical and postmortem findings of the first photograp hically documented case of asplenia and interrupted inferior vena cava and the anatomic findings of 5 previously reported cases. A brief rev iew of the various hereditary patterns of visceral situs abnormalities suggests that, at least in some cases, the asplenia and polysplenia s yndromes are etiologically and pathogenetically interrelated.
