Detailed Structure and Function of Lymph Nodes

Detailed Structure and Function of Lymph Nodes

Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Summary

This summary is machine-generated.

Intranodal lymphangiogram (INL) successfully identified lymphaticovenous anastomoses in all patients with persistent chylous leakage. This technique confirmed leakage in the femoral or pelvic region, aiding in treatment planning.

Area of Science:

Vascular Surgery
Interventional Radiology
Gastroenterology

Background:

Persistent chylous leakage is a challenging complication after esophageal cancer surgery.
Conservative treatment often fails to resolve chylous leakage.
Accurate identification of lymphaticovenous communication is crucial for effective management.

Purpose of the Study:

To evaluate the technical success and imaging findings of intranodal lymphangiogram (INL).
To assess the utility of INL in diagnosing lymphaticovenous anastomoses in patients with chylous leakage.
To report the imaging characteristics of INL in this patient cohort.

Main Methods:

Ultrasound-guided puncture of inguinal or femoral lymph nodes using a 23-gauge needle.
Intranodal lymphangiogram (INL) performed with manual lipiodol injection.
Percutaneous cisterna chyli puncture and thoracic duct embolization when feasible.

Main Results:

INL was technically successful in all four studied patients.
Lymphaticovenous anastomoses were confirmed in the femoral or pelvic region in all patients.
Successful thoracic duct embolization was achieved in three out of four patients.

Conclusions:

INL is a successful technique for diagnosing lymphaticovenous anastomoses in patients with chylous leakage.
Lipiodol leakage into veins via lymphaticovenous anastomoses was consistently observed.
INL provides valuable imaging findings for guiding further intervention.
