Ten cadaveric great saphenous vein systems have been dissected to assess the relationship between the valves and the termination of venous tributaries. Such tributaries were classified on the basis of size, competence and course, and the percentage of each of four classes terminating within 1 cm of each valve site has been assessed. Above the knee, valves were more numerous, closer together, and two-thirds of competent tributaries terminated within 1 cm of them, this relationship being weaker for other classes of tributary. Below the knee, less than 50% of any class of tributary was related to valves. Reference to the position of valves is not recommended as the sole method of locating potential arteriovenous fistulae.
解剖了十具尸体的大隐静脉系统，以评估瓣膜与静脉分支末端之间的关系。这些分支根据大小、功能和走行进行分类，并评估了在每个瓣膜部位1厘米范围内终止的四类分支中每一类的百分比。在膝盖以上，瓣膜更多、间距更近，三分之二功能正常的分支在距瓣膜1厘米范围内终止，而对于其他类型的分支，这种关系较弱。在膝盖以下，任何类型的分支中与瓣膜相关的不到50%。不建议仅以瓣膜位置作为定位潜在动静脉瘘的唯一方法。
