Intranodal lymphangiography has replaced conventional pedal lymphangiography and has advanced lymphatic intervention. In this method, a lymph node is punctured and Lipiodol is injected to visualize the subsequent lymphatic vessels. This has facilitated the widespread adoption of lymphatic interventional radiology due to the simplicity of the technique and the shortened examination time of the procedure, which allows easy mapping of lymphatic vessels and lymphatic fluid dynamics. With this technique, lymphatic embolization was achieved by injecting an embolic substance into the lymph nodes upstream of the lymphatic leak. Although complications associated with lymphangiography are rare, caution should be exercised due to potential complications associated with the use of Lipiodol. This study summarizes intranodal lymphangiography techniques, complications, and lymphatic embolization.
淋巴结内淋巴管造影已取代传统的足背淋巴管造影，并推动了淋巴介入技术的发展。在这种方法中，穿刺一个淋巴结并注入碘油以显示后续的淋巴管。由于该技术操作简单且检查时间缩短，便于淋巴管和淋巴液动力学的轻松成像，这促进了淋巴介入放射学的广泛应用。通过这种技术，将栓塞物质注入淋巴漏上游的淋巴结来实现淋巴栓塞。尽管淋巴管造影相关的并发症很少见，但由于使用碘油可能存在潜在并发症，仍应谨慎操作。本研究总结了淋巴结内淋巴管造影技术、并发症及淋巴栓塞。
