Morphologic and functional anatomy of the subclavian veins.
50 jugulo-subclavian venous junctions were removed to study the endovenous structures of the subclavian vein and of this junction. The diameter of the subclavian vein is always less than that of the internal jugular vein. Valvules were constantly found, whereas endovenous structures such as those found in the ilio-caval junctions were very rare. In view of these findings, these structures may be regarded as of embryologic origin.
