what the risks are lymphatic system, lymphangiogram, lymphography, lymphangiography, lymphatic system is made up of lymph nodes, lymph vessels, lymphatics, link the lymph nodes, nodes harbor a type of white blood cell, lymphocytes, helps fight infections, an infection is present, lymph nodes swell, help proliferate the white blood cells, try to trap the organisms, causing the infection, lymph nodes also function to filter, trap cancer cells, lymph nodes, vessels, seen on an x-ray, a contrast material, radioisotope, radioactive compound, injected, system to visualize it, test is performed, hospital radiology department, health care provider's office, x-ray technician, leg, arm swelling is evaluated, offered a sedative to help relax, put, specially constructed chair, on the x-ray table, skin of each foot is cleansed, a small amount, blue dye is injected between the toes, webbing, 15 minutes, thin, bluish lines appear on the top, the foot, identifies the lymphatics, a local anesthetic is given, a small incision is made into one, the larger blue lines, a needle, catheter, a thin flexible tube, inserted into a lymphatic channel in each foot, a contrast medium is injected into each foot at a very slow rate, 60 to 90 minutes, all the contrast medium to be injected, a fluoroscope, a special x-ray machine that projects the images on a tv monitor, follow the dye, spreads, the lymphatic system up the legs, groin, along the back, the abdominal cavity, once the contrast medium is injected, catheter is removed, incisions, stitched, bandaged, x-rays, the legs, pelvis, abdomen, chest areas, next day, another set of x-rays taken, a site of cancer, breast, melanoma, studied to evaluate spreading, a mixture of blue dye, a radioactive tracer is injected next, mass, special cameras detect the spread of tracer, along lymph channels to outlying nodes, a surgeon, use the visible blue dye, radioactivity, nodes to guide biopsy, adjacent tissues, arm pit, breast cancer, routes of cancer spread, inform the health care provider, pregnant, have bleeding problems, mention, 've had allergic reactions to x-ray contrast material, iodine-containing substance, must sign a consent form, restrict diet to clear liquids, wish to empty bladder, undergoing lymphangiography, sentinel lymph node biopsy, in breast cancer, melanoma, prepare, the operating room, a surgeon, anesthesiologist, discuss how to prepare, the procedure, infants, children, procedure depends on child's age, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, a brief sting, needle, blue dye injected between the toes, another brief sting, the injection, the local anesthetic, a feeling of pressure, the contrast medium is injected, some discomfort behind the knees, groin area, incisions, sore, blue dye, color the urine, stool, 48 hours, skin, possibly the vision, take on a bluish cast temporarily, test, in conjunction, senitel lymph node biopsy, evaluate the possible spread of cancers, effectiveness of cancer therapy, use of contrast, x-rays, help determine the cause of swelling in an arm, leg, check, parasitic, organisms that live on another, enlarged nodes, swollen glands, foamy appearance, indicate a lymphatic cancer, nodes, parts, the nodes that, not fill, the contrast material, indicate a cancer spreading throughout the system, blockage, the lymph vessels, tumor, infection, trauma, prior surgical disruption, the lymph pathways, lymphangiograms, in conjunction, senitel node biopsy, simply identify the draining pathways near a mass, spread of cancer, determined after biopsy of visualized nodes, additional conditions under which the test performed, hodgkin's lymphoma, non-hodgkin's lymphoma, possibility of an reaction, contrast medium, an infection is possible, site, the injection, dye, contrast material, a fever, inflammation, the lymph vessels, low radiation exposure, most experts feel that the risk of most x-rays is smaller than other risks we take every day, pregnant women, children, more sensitive, the x-ray, contrast medium, stay, in the nodes, up to 2 years.
