Masterclass: Duplex Ultrasound of the Superficial Leg Veins (下肢浅静脉双工超声检查大师课程)
课程总时长约为8至12小时，学员可以自主完成学习，也可以将本课程作为临床实践操作培训班（Hands-on Workshop）的补充课程。
课程内容涵盖下肢静脉解剖学、静脉疾病诊疗中的超声检查基础、静脉血流生理学、病理生理机制的讲解，以及各种血流激发试验和操作方法。
此外，课程还详细介绍大隐静脉、小隐静脉、副隐静脉、静脉属支及交通静脉（穿通静脉）的病理改变及其超声检查方法。
课程还包括浅静脉血栓形成（SVT）的诊断，并提供浅静脉血栓形成治疗方案选择的决策指导。
同时，课程还涉及水肿的超声检查，以及在下肢静脉超声检查过程中可能发现的其他病理性改变和异常表现。
This e-learning course provides theoretical training in Duplex ultrasound of the superficial leg veins, including theory videos (lectures), downloadable PDFs, questions, and practical application videos with patients.
The course duration is 8-12 hours and can be completed independently or as a supplement to the hands-on workshop in clinical practice.
The content covers the anatomy of the leg veins, the fundamentals of ultrasound in phlebology, venous flow physiology, explanations of pathophysiology, and various provocation maneuvers. It also addresses the pathology of the great saphenous vein, small saphenous vein, accessory veins, tributaries and perforator veins.
Furthermore, the course includes the diagnosis of superficial vein thrombosis, providing decision-making aids for SVT therapy. It also covers ultrasound examination of edema and other pathological findings that may be observed during a leg vein examination.
