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 six cases of the 28 cadavers (21.4%) and they were classified into 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. (English translation of J Jpn Coll Angiol 2013; 53: 43-47).
