Nodal Lymphangiography and Embolization for Postoperative Lymphatic Leakage.

Abstract

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.
