Description: Lymphangiography is an imaging test that uses X-rays to visualize the lymphatic system of the human body. This technique is based on the injection of a contrast medium into the lymphatic vessels, which highlights their structure and function in the obtained images. Lymphangiography is particularly useful for assessing the status of lymph nodes and detecting possible obstructions, tumors, or inflammations in the lymphatic system. Through this test, doctors can obtain valuable information about lymphatic circulation, which is crucial for the diagnosis and treatment of various medical conditions. The clarity of the generated images allows specialists to identify abnormalities and plan surgical interventions or specific treatments. In summary, lymphangiography is an essential diagnostic tool in modern medicine, contributing to a better understanding of pathologies related to the lymphatic system.
History: Lymphangiography was developed in the 1930s when advances in radiology and the understanding of the lymphatic system allowed for the creation of this technique. Initially, an oil-based contrast medium was used, but over time the formulation was improved to enhance the safety and effectiveness of the procedure. Over the years, lymphangiography has evolved with the introduction of more advanced technologies, such as magnetic resonance imaging and computed tomography, which have complemented and, in some cases, replaced this technique in clinical practice.
Uses: Lymphangiography is primarily used to diagnose diseases related to the lymphatic system, such as lymphedema, tumors, and infectious diseases. It is also useful in planning oncological surgeries, as it allows surgeons to visualize the location of affected lymph nodes. Additionally, it can be employed to assess the effectiveness of previous treatments and monitor the progression of lymphatic diseases.
Examples: A practical example of the use of lymphangiography is in patients with breast cancer, where it can assess the involvement of axillary lymph nodes before surgery. Another case is in patients with lymphedema, where lymphangiography helps determine the cause of fluid accumulation in the limbs and guide appropriate treatment.
