What is lymphangiography?
Lympangiography is a type of medical imaging study that is used to visualize the lymphatic system, a network of blood vessels and nodes that moves through the lymph throughout the body. This procedure is performed in a hospital or clinical environment and is under the supervision of a radiologist or medical technician. The purpose of lympangiography is to collect information that can be diagnosed to learn more about why the patient experiences specific symptoms and potentially excludes certain health problems.
patients are often calmed for this procedure because it can be time consuming and unpleasant. The patient will be upside down, but relaxed as a result of sedative, making lymphangiography more pleasant. Lympangiography begins with the injecting the dye into the legs or hands. This dye will flow into the lymphatic system and will be visible, allowing a doctor, nurse or technique to insert the catheter into one of the ships that bears a lymph.
The catheter is used to include a contrasting dye, also known as a contrasting agent.The contrast dyes are Radiopaque, which means it is displayed in X -ray images. The movement of the contrast dye is monitored using a fluoroscope that generates a moving X -ray image of the body. Once spread in the lymphatic system or area of interest, you can take sets of X -rays. Other X -rays can be taken the following day.
After the procedure, the patient may feel slightly painful, especially behind his knees. Usually body fluids, such as urine, are also colored by dye used at the beginning of the procedure to find lymphatic vessels, and this is solved in a few days as soon as the body expresses all dye. The results of lympangiography can be read immediately or interpreted at another time and discussed with the patient later.
One reason to order lymphyangiography is concerned about blocking in the lymphatic system. If the patient has a swollen leg or arm that the assumption ofLáda is the result of lymph backup, lymphangiography can be used to find a blockade to solve it. This type of medical imaging can also be used to check the symptoms of cancer, although it is possible to obtain false negative on lympangiography, so a clear result does not necessarily mean that the patient does not have cancer.
