Minor tributary veins of the common femoral vein near the saphenofemoral junction – A postmortem study

Abstract

Objectives Recurrent varicose veins after surgery are a frequent burden and the saphenofemoral junction is the most common source of reflux. Pre-existing branches of the common femoral vein near the saphenofemoral junction, which may increase due to haemodynamic or other reasons, could play a role in the development of recurrent varices. There exist only a few anatomical data about the prevalence of these minor venous tributaries of the common femoral vein near the saphenofemoral junction. Therefore, this study aimed to elucidate their frequency and distribution. Method A total of 59 veins from 35 anatomical donors were dissected. The common femoral vein with the adherent parts of the profunda femoris vein and the great saphenous vein was exposed and analysed ex situ. The number of minor tributaries to the common femoral vein was counted and their distances to the saphenofemoral junction as well their diameters were measured. Results We could identify up to 10 minor tributaries of the common femoral vein below the level of the great saphenous vein as far as 6 cm distally and up to four veins above the level as far as 5 cm proximally. The mean diameters of these vessels ranged from 0.5 to 11.7 mm. Most of these vessels were located near the saphenofemoral junction and 3 cm distally. Directly opposite to the opening of the great saphenous vein we could find at least one minor tributary of the common femoral vein in 57%. Conclusions There exist a vast number of minor tributaries of the common femoral vein and they are mainly located near the saphenofemoral junction. Nevertheless, their role in the development of recurrent varices is still unclear and further studies are necessary.

“…Множественное впадение притоков без формирования единого ствола, т. е. плексиформная конфигурация проксимального отдела большой подкожной вены наиболее сложна для хирургического лечения, так как существует высокий риск повреждения множественных извитых тонкостенных вен при их выделении, а некоторые притоки и вовсе остаются незамеченными и могут являться источником кровотечения [38] (рис. 3).…”
