BackgroundOur study aims to enhance the understanding of lymph node venous networks (LNVNs) by summarising their anatomical, sonographic features, and reflux patterns.MethodWe examined 241 legs from 141 patients with primary chronic venous disease (CVD) using duplex ultrasound.ResultsThe 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.ConclusionThis 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及血流模式的声像图特征

背景我们的研究旨在通过总结淋巴结静脉网络 (LNVN) 的解剖学、超声检查特征和反流模式来增强对淋巴结静脉网络 (LNVN) 的了解。方法我们使用双功超声检查了 141 名原发性慢性静脉疾病 (CVD) 患者的 241 条腿。结果结果表明存在差异LNVN 的形状、大小、血管分布和回声性。反流的腹股沟浅淋巴结显得稍大，肺门动脉速度较高。关于连接，LNVN 内的静脉血流主要通过隐股交界处 (SFJ)、前副大隐静脉 (AAGSV) 和大隐静脉 (GSV) 引流。观察到大量 LNVN 与大腿前外侧支流相关。该研究还确定了 LNVN 内的瓣膜尖点。结论该研究显示原发性 LNVN 的患病率为 12%。了解 LNVN 的解剖和血流动力学特征可为治疗策略提供信息，并可能有助于预防静脉曲张的复发。
