Lymphography Direct

Direct lymphography

Direct lymphography is a method of visualizing the lymphatic system in which a contrast agent is injected directly into a lymphatic vessel that has previously been exposed surgically.

During direct lymphography, the surgeon exposes and cannulates the lymphatic vessel. Then a radiopaque substance, most often a solution of iodine or barium salts, is injected through the cannula. After this, radiography or lymphangiography is performed, which allows visualization of the lymphatic vessels and nodes where the contrast enters.

Direct lymphography allows you to study in detail the structure and topography of the lymphatic pathways in the area of ​​interest. It is used mainly for research purposes and less often for diagnosing pathological changes in the lymphatic system. The disadvantage of this method is its invasiveness, since surgery is required.

The lymphatic system is an important part of the body's overall metabolism, removing excess fluid and other substances, including allergens, pathogens, and waste products from body tissues. Lymph flow prevents congestion, helps reduce swelling, helps lymphatic vessels remove toxic substances from tissues and reduces the risk of developing metastatic formations. Lymphatic surgery is performed by exposing individual lymph nodes located along one or more lymph vessels, followed by intraoperative flushing with lymph or a contrast agent injected under pressure through a special guidewire to improve access to the nodes. The operation is performed under the control of ultrasound and/or echography, which makes it possible to identify any neoplasms and exclude the possibility of damage to adjacent anatomical structures. This helps to avoid many complications and achieve much better results. A significant advantage of the method is the possibility of repeating it. If inguinal lymph nodes are present, the operation can be repeated at intervals of several months until the final condition is achieved.
