Abstract
The patterns of collateral circulation which develop following obstruction of the inferior vena cava have been classically divided into three groups depending upon the level of obstruction, i.e., infrarenal, middle caval, and upper caval. The portal vein can play an active role at all three levels. Multiple potential routes to the portal vein are described and 6 cases are presented.
