Lymphadenography

Lymphadenography is a medical imaging technique that is used to study the lymphatic system of the human body. It involves injecting a contrast agent into the lymphatic vessels and then visualizing them on an X-ray or computed tomography.

The lymphatic system consists of lymphatic vessels and nodes that are located throughout the body. It plays an important role in protecting the body from infections and other diseases. Lymph nodes play the role of filters, where lymph is cleansed from bacteria, viruses and other foreign substances.

In lymphadenography, contrast material is injected into a vein in the arm or leg and then slowly spreads through the lymphatic vessels. This is followed by an X-ray or CT scan to visualize the lymphatic system.

This test method can detect the presence of tumors, infections or other diseases of the lymphatic system. In addition, lymphadenography can be used to determine the stage of cancer, as well as to evaluate the effectiveness of treatment.

However, like any other medical imaging technique, lymphadenography has its limitations. For example, it may be painful for the patient, especially if the contrast agent causes an allergic reaction. In addition, this method is not always available to all patients, as it requires special equipment and qualified specialists.

**Lymphadenoscintigraphy and lymphadenography** Lymphangitis with the involvement of lymphatic vessels, lymphatic cavities in the tissue with walls of fresh granulations; regional inflammatory infiltrates; lymphangioma; foreign bodies; condition after removal of skin tumors - non-myelolytic radiation methods are used only for a definitive diagnosis

What lymphography shows: tumors and soft tissue cysts, tumor metastases in regional lymph nodes, inflammatory lymphatic lesions, and it is also used to assess the radicality of surgical treatment of malignant tumors.

Normally, lymphatic vessels are easily compressed by soft tissue bruising or by simple cutting of the skin and subcutaneous tissue. Even if the skin is punctured or damaged, the vessels stretch, but their lumen remains patent after injury. In case of bruise of subcutaneous fatty tissue, collateral collateral communication appears early and does not lead to serious consequences. If, as a result of a bruise, a lymphatic vessel ruptures, then in the first days this is manifested by enlarged lymph nodes at the site of injury and bruising. After these manifestations, the collateral flow passes without noticeable changes. Gradually, the tone of the vessels is restored, and they expand again. Observation of the skin at the site of exposure confirms the tendency for scarring. But after a few months, cramps may appear again
