title: [Anatomic and histologic study of the valves of the internal jugular veins].
abstract: In 200 dissections of internal jugular veins, the valves were investigated with regard to their constitution, their macroscopic and their microscopic anatomy. In 88% of the cases, an ostial valve was found. The cusp of each consists of two parts in 77%, of only one part in 16%, and in 7% of three parts. In 12% these valves are not found. The structure, the configuration, the topography of these valves are explained. The stroma of the valve consists of collagen and elastic fibrils. The surface of the luminal and parietal part is covered by endothelial cells with elastic and muscular fibers close to the attachment of the cusp to the vein wall.
