Abstract

Obstruction of the inferior vena cava(IVC) is an uncommon condition, and the collateral pathway variesaccording to the level, extent, duration and the cause of obstruction. Membranous obstruction of IVC in itshepatic portion might be one of the principal cause among Korean, though not reported till now. Analytical studywas perfomred in 26 cases of IVC obstruction with various cause. 1. The level of the obstruction showed relativelyeven distribution as follows, upper caval in 11 cases, middle caval in 6 cases and infrarenal in 9 cases. 2. Themain cause of upper caval obstruction was membranous obstruction . 3. As a whole, the main collateral pathway wasthe central route(22 case:85%). 4. Characteristic collateral pathway unique to upper caval obstruction wastranshepatic vanous collateral, developed between the obstructed segment and unobstructed segment of IVC. 5.Scalloping of left cardiac border produced by pericardiophrenic venous collateral was characteristic simple chestX-ray finding in IVC obstruction.
