LYMPHANGIOGRAM
What Is A Lymphangiogram?
A lymphangiogram is a study of the lymphatic system.
Preparation For Test
There is no preparation.
How Is This Study Done?
A small needle is introduced into the webbing of the toes. Through this needle a blue dye will be injected which will enable the Radiologist to see your lymphatic vessels. A small incision is then made on the top of each foot. Your lymphatic vessels will then be exposed. A small needle is then placed in one vessel in each foot and X-ray contrast is injected into each of these vessels.
How Long Will This Test Take?
Due to the fact that the lymphatic vessels are so small, the injection is very slow. The exam usually takes 2-3 hours.
Is There Any Pain During The Exam?
You may have some slight discomfort when the blue dye is injected. You may also have a stinging sensation on the top of the foot when the numbing medication, Xylocaine, is injected before the incision is made.
Is There A Follow Up Visit After The Initial Exam?
You will be asked to return to radiology the day after the exam for a series of X-rays. This will take approximately 20 minutes.
Could I Have A Reaction To The Dye?
Some people do have reactions. The reactions that we consider minor are nausea, vomiting, pain in the extremities during injection and dermatitis (inflammation of the skin). More serious reactions include asthmatic attack, convulsions, infection, swelling of lower extremities and embolism. These are not common reactions and if any are experienced please notify your physician immediately.
What Does A Lymphangiogram Show?
It can show tumors, diagnose lymphoma and determine the cause of leg swelling.
Who Will Do This Test?
A Radiologist will perform the study with assistance from a Radiologic Technologist. The Radiologist is a physician whose specialty is radiology.
After Your Lymphangiogram
Take TYLENOL (2 - 325 mg. tablets every 3-4 hours) for mild pain, OR, take IBUPROFEN (Advil, Nuprin, Motrin IB) I or 2 - 200 mg. tablets every 3-4 hours for moderate pain. Continue to take your usual medications and your normal diet.
