Histological Study on the Left Common Iliac Vein Spur

Abstract

The spur occasionally seen in a left common iliac vein was investigated by anatomical and histological examination of cadavers so the occurrence mechanism could be discussed. Spurs were found in 6 cases of the 28 cadavers (21.4%) and they were classified a few different kinds of composition of endosporia, tunica media and adventitia. It is considered that there may be different formation mechanisms and stages even in cases of similar anatomical finding.
