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.
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.
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%.
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.
手术后复发的静脉曲张是一种常见的负担，而股隐交界处是最常见的反流源。股隐交界处附近的股总静脉原有分支（可能由于血流动力学或其他原因而增加）可能在复发静脉曲张的发展中起作用。关于股隐交界处附近股总静脉这些小属支的存在，仅有少数解剖学数据。因此，本研究旨在阐明其频率和分布。
共解剖了 35 具解剖供体的 59 条静脉。显露股总静脉及其与股深静脉和大隐静脉的粘连部分，并在离体状态下进行分析。计数股总静脉的小属支数量，并测量其距股隐交界处的距离及其直径。
我们可以在大隐静脉下方识别多达 10 条股总静脉的小属支，最远可达 6cm 处，在大隐静脉上方可识别多达 4 条股总静脉，最远可达 5cm 处。这些血管的平均直径范围为 0.5 至 11.7mm。这些血管中的大多数位于股隐交界处附近和 3cm 处。在大隐静脉开口的正对面，我们可以在 57%的情况下至少发现一条股总静脉的小属支。
股总静脉存在大量小属支，主要位于股隐交界处附近。然而，它们在复发静脉曲张的发展中的作用仍不清楚，需要进一步研究。
