Number and location of venous valves within the popliteal and femoral veins – a review of the literature

Abstract

Although deep venous insufficiency is common and important, the anatomy of deep vein valves is poorly understood. The aim of this study was to investigate the location, number and consistency of venous valves in the femoral and popliteal veins in normal subjects. A detailed literature search of PubMed was performed. Abstracts and selected full text articles were scrutinised and relevant studies published between 1949 and 2010 reporting anatomical details of deep vein valves were included. From 7470 articles identified by the initial search strategy, nine studies with a total of 476 legs were included in this review. All studies were cadaveric and subjects ranged from stillborn fetuses to 103 years of age. Studies suggested that femoral veins contain between one and six valves, and popliteal veins contain between zero and four valves. Deep vein valves were consistently located in the common femoral vein (within 5 cm of the inguinal ligament), the femoral vein (within 3 cm of the deep femoral vein tributary) and in the popliteal vein near the adductor hiatus. Valves are consistently located at specific locations in the deep veins of the leg, although there is often significant variability between subjects. Further anatomical and functional studies using new imaging modalities available should target these areas to identify whether certain valves play a more important role in venous disease. This may guide us in the development of new treatment options for patients with deep venous disease.
