Abstract

Background: Our study aims to enhance the understanding of lymph node venous networks (LNVNs) by summarising their anatomical, sonographic features, and reflux patterns.

Method: We examined 241 legs from 141 patients with primary chronic venous disease (CVD) using duplex ultrasound.

Results: The findings indicated variations in the shape, size, vascularity, and echogenicity of LNVN. The superficial inguinal lymph node with reflux appeared slightly larger, exhibiting higher velocities in the hilar artery. Regarding connections, venous flow within LNVN was predominantly drained through the saphenofemoral junction (SFJ), anterior accessory great saphenous vein (AAGSV), and great saphenous vein (GSV). A significant number of LNVNs were observed to be associated with anterolateral thigh tributaries. The study also identified valve cusps within LNVN.

Conclusion: This study revealed a 12% prevalence of primary LNVN. Understanding the anatomical and haemodynamic features of LNVN informs treatment strategies and potentially helps prevent the recurrence of varicose veins.

原发性慢性静脉疾病患者淋巴结静脉网络和血流模式的声像图特征。

研究背景我们的研究旨在通过总结淋巴结静脉网（LNVN）的解剖学、声像图特征和回流模式，加深对淋巴结静脉网的了解：方法：我们使用双工超声波检查了 141 名原发性慢性静脉疾病（CVD）患者的 241 条腿：结果：研究结果表明，腹股沟浅表淋巴结的形状、大小、血管和回声存在差异。出现反流的腹股沟浅淋巴结看起来稍大，在腹股沟动脉中的速度较高。在连接方面，LNVN 内的静脉流主要通过隐股交界处（SFJ）、大隐静脉前附件（AAGSV）和大隐静脉（GSV）引流。据观察，大量 LNVN 与大腿前外侧支流有关。研究还在 LNVN 中发现了瓣膜尖头：这项研究显示，原发性 LNVN 的发病率为 12%。了解 LNVN 的解剖和血流动力学特征可为治疗策略提供参考，并有助于预防静脉曲张复发。
