Intranodal embolization effectively treats persistent groin lymphoceles. This minimally invasive procedure using n-butyl cyanoacrylate glue demonstrated a 100% success rate with no complications in a recent study.

Area of Science:

Vascular Surgery
Interventional Radiology
Lymphatic Medicine

Background:

Persistent lymphatic leakage, particularly groin lymphocele, poses a significant clinical challenge.
Current treatment options for persistent lymphatic leakage may be invasive or have limited efficacy.
Intranodal embolization is an emerging minimally invasive technique for lymphatic leakage.

Purpose of the Study:

To describe the procedural details of intranodal embolization for groin lymphocele.
To evaluate the efficacy and safety of intranodal embolization for persistent groin lymphocele.
To assess the technical and clinical success rates of intranodal embolization.

Main Methods:

Retrospective chart review of nine consecutive patients with groin lymphocele treated between January 2017 and December 2019.

Keywords:

Groin lymphocele Lymphatic embolization Lymphatic intervention

Intranodal lymphangiography with iodinated contrast to identify lymphatic leakage.

Embolization using n-butyl cyanoacrylate glue mixed with iodized oil.

Main Results:

The primary etiologies of lymphocele were iatrogenic (inguinal vessel access, lymph node biopsy) and trauma.
100% technical and clinical success rates were achieved for both lymphangiography and intranodal embolization.
The median treatment duration was 2 days, with no acute or chronic complications observed during a median follow-up of 9 days.

Conclusions:

Intranodal embolization is a promising treatment for persistent groin lymphocele, offering a high success rate and short treatment duration.
The procedure using n-butyl cyanoacrylate glue is safe and effective, with no observed complications.
Further research is warranted to validate these findings and establish intranodal embolization as a standard treatment option.
