Nodal Lymphangiography and Embolization for Postoperative Lymphatic Leakage

Area of Science:

• Interventional Radiology
• Lymphatic Imaging
• Vascular Medicine

Background:

• Intranodal lymphangiography has become the preferred method over conventional pedal lymphangiography.
• It has significantly advanced the field of lymphatic intervention.

Purpose of the Study:

• To summarize intranodal lymphangiography techniques.
• To detail potential complications associated with the procedure.
• To explain the application of lymphatic embolization using this method.

Main Methods:

• Puncturing a lymph node and injecting Lipiodol to visualize lymphatic vessels.
• Mapping lymphatic vessels and dynamics.
• Performing lymphatic embolization by injecting embolic substances upstream of lymphatic leaks.

Main Results:

• Intranodal lymphangiography allows for simple and rapid mapping of lymphatic vessels and fluid dynamics.
• Lymphatic embolization is effectively achieved by targeting upstream lymph nodes.
• The technique has facilitated widespread adoption in lymphatic interventional radiology.

Conclusions:

• Intranodal lymphangiography is a valuable advancement in lymphatic intervention.
• While generally safe, potential complications related to Lipiodol use require caution.
• The technique simplifies lymphatic visualization and enables targeted embolization for lymphatic leaks.
