Lymphography Indirect

Lymphography is a diagnostic method that allows you to visualize the lymphatic system and its structures. It is used to detect tumors and other diseases related to the lymphatic system.

Lymphography can be direct or indirect. With direct lymphography, a contrast agent is injected directly into the lymphatic vessels, which allows you to get a more accurate picture of the state of the lymphatic system. However, this method can be hazardous to the patient's health and requires special equipment and experience.

Indirect lymphography is a safer and less invasive method. In indirect lymphography, a contrast agent is injected into the soft tissue around the lymph nodes or vessels. It then enters the lymphatic system through lymphatic capillaries. This allows you to image the lymphatic system without directly affecting it.

One of the advantages of indirect lymphography is its safety. The contrast agent does not penetrate the circulatory system, which reduces the risk of side effects. In addition, this method provides a clearer image of the lymphatic system than direct lymphography.

However, indirect lymphography has its limitations. For example, it does not always allow one to accurately determine the location of a tumor or other pathologies. Also, this method is not suitable for patients with severe heart or kidney disease, since the contrast agent may cause complications.

In general, indirect lymphography is an important method for diagnosing lymphatic diseases. It allows you to get a more accurate picture of the state of the lymphatic system and helps in choosing the right treatment tactics.

Lymphography is not direct. L., Lymphotomography - obtaining and recording images of lymphatic vessels and ducts by introducing a contrast agent directly into the lymph flow. It is mainly used to determine the patency of the lymphatic ducts. During fluoroscopy, it is used to determine the load on the segments of the thoracic lymphatic duct, and also as a means of differential diagnosis of postoperative pleural adhesions. Lymphoradiography is used in the diagnosis of diseases of the lymphatic system, tumor and inflammatory processes.\n\nSuperficial lymphography of L., or paravasal lymphography (K. Liebe (Kirby) and G. Olmsted in 1929) - the introduction of a contrast agent into the serosa. The method is used mainly in X-ray radiology to detect lymphectasia, nodes and other signs of lymphangitis and lymphadenitis. L. is indicated primarily when the primary localization of a cancerous tumor is unclear, especially if it arose outside the irradiated field. Lymphaticumography by K. Liebe and F. Pennington (1935) is a method of targeted study of the lymph nodes of the neck, mediastinum and abdominal cavity during inflammatory, suppurative processes, cancer, hypertrophic mesenchymal dysplasia and other diseases. Used intraoperatively during examination of affected lymph nodes in various phases of contrast. In this case, the mobility and displacement of nodes is subject to assessment

**Indirect lymphography (IRL)** is a method of x-ray examination, which is based on the introduction of a contrast agent solution through the veins to the soft tissues and bloodstream, and then its movement in the lymphatic tract. The use of indirect lymphography has become an effective diagnostic tool in determining the localization of pathological processes, diagnosing lymphedema and evaluating various surgical interventions in the lymphatic system.

RLG allows you to visualize the movement of the contrast agent in the lymphatic bed, especially in the superficial layers of tissue, which are the area where most malignant tumors are located. With the help of these changes, it is possible to identify the presence of malignant neoplasms and the degree of their prevalence, determine the location of lymph collectors and drainage paths. Traditional X-ray is also the basis for indirect lymphography, i.e. using a contrast mass for x-ray studies. This contributed to the emergence of the term “x-ray lymphography” as a more accurate description of this research method.
