The deep femoral vein generally has individual differences in origin, course, tributary, caliber, and quantity. However, systematic research on deep femoral vein variations remains insufficient. Given this, this study used anatomical observation to reveal the types and ratios of variations in the deep femoral vein and its tributaries.
This study selected 63 gross specimens of intact lower extremities and dissected their 126 lower limbs layer by layer to explore variations in the deep femoral vein and its tributaries.
A total of 15 lower limbs exhibit variations in the deep femoral vein and its tributaries, of which 93% were unilateral. No correlation was found between the mutations and gender. They can be generally classified into three types: variations in the small saphenous vein branch of the deep femoral vein (7.14%), variations in the popliteal vein branch of the deep femoral vein (3.96%), and multiple deep femoral vein variations (0.79%).
Variations in the deep femoral vein and its tributaries are not rare and can achieve a variation rate of 11.9%. Moreover, 93% of the variations involve tributaries of the deep femoral vein, among which 60% occur in the small saphenous vein branch, and approximately 30% are related to the popliteal vein branch. The variation diversity can lay a theoretical foundation for clinical diagnosis and treatment.
股深静脉在起源、走行、属支、管径和数量上通常存在个体差异。然而，关于股深静脉变异的系统研究仍然不足。鉴于此，本研究采用解剖学观察来揭示股深静脉及其属支的变异类型和比例。
本研究选取63例完整下肢大体标本，对其126条下肢进行逐层解剖，以探究股深静脉及其属支的变异情况。
共有15条下肢出现股深静脉及其属支变异，其中93%为单侧变异。变异与性别之间未发现相关性。它们大致可分为三种类型：股深静脉小隐静脉分支变异（7.14%）、股深静脉腘静脉分支变异（3.96%）和多条股深静脉变异（0.79%）。
股深静脉及其属支变异并不罕见，变异率可达11.9%。此外，93%的变异涉及股深静脉属支，其中60%发生在小隐静脉分支，约30%与腘静脉分支有关。变异的多样性可为临床诊断和治疗奠定理论基础。
