Abstract

A malformation of azygos and hemiazygos system were observed from the cadaver for anatomy practice in College of Medicine, Chungnam National University. The observing results were as followings ; Hemiazygos vein was connected with left
superior
vena cava and drained into coronary sinus, which engorged enough to fill up with blood about 20㏄ to 30㏄. Communicating pathway from hemiazygos vein to azygos veln wasn't found the diameter of left brachiocephalic vein was very small, about 2㎜
to
3㎜.
And, the diameter of left internal jugular vein was smaller than that of right infernal jugular vein. In this case, the azygos and hemiazygos system ceased its development at early embryologic stage (around 7 week embryo) and didn't progress
into
next
stage.
