Lymphangiography, extremity only, unilateral, radiological supervision and interpretation
CPT4 code
Name of the Procedure:
Lymphangiography, Extremity Only, Unilateral, Radiological Supervision and Interpretation
Summary
Lymphangiography is a specialized imaging procedure used to visualize the lymphatic vessels in one arm or leg. This is done under the guidance and interpretation of radiology experts using contrast dye and X-rays.
Purpose
Lymphangiography helps diagnose and evaluate conditions involving the lymphatic system, such as lymphatic blockages, lymphangitis, lymphedema, or cancers that spread through the lymphatic system. The goal is to obtain a clear image of the lymphatic vessels to guide treatment decisions and plan appropriate interventions.
Indications
- Swelling or lymphedema of an extremity
- Suspected lymphatic obstruction or blockage
- Assessment before and after lymph node surgery
- Evaluation of lymphatic spread of cancer
Preparation
- Patients may be asked to fast for a few hours before the procedure.
- Inform the healthcare provider of any allergies, especially to contrast dye.
- Blood tests and imaging studies may be carried out prior to the procedure.
Procedure Description
- A small incision is made to access a lymphatic vessel in the affected extremity.
- A contrast dye is injected into the lymphatic vessel.
- X-ray images are taken to track the flow of the dye through the lymphatic vessels.
- Radiologists interpret the images to identify abnormalities.
- The procedure is typically done under local anesthesia to numb the injection site.
Duration
The procedure usually takes about 1-2 hours.
Setting
Lymphangiography is typically performed in a hospital's radiology department or a specialized imaging center.
Personnel
- Radiologist (leads the procedure)
- Radiologic technologist (assists with imaging)
- Nurse (provides patient care and support)
Risks and Complications
- Allergic reaction to the contrast dye
- Infection at the injection site
- Bruising or bleeding
- Discomfort or pain during and after the procedure
- Rarely, damage to lymphatic vessels
Benefits
- Accurate diagnosis and assessment of lymphatic abnormalities
- Better treatment planning
- Potential for early detection and intervention
Recovery
- Mild discomfort or bruising at the injection site may be experienced.
- Most patients can resume normal activities within 24-48 hours.
- Follow-up appointments may be scheduled to discuss results and next steps.
Alternatives
- Ultrasound for non-invasive evaluation
- MRI or CT scan with contrast for a different imaging approach
- Physical examination and clinical assessment for preliminary evaluation
Patient Experience
During the procedure, patients may feel a slight prick and pressure when the contrast dye is injected. Mild pain or swelling may occur at the injection site but is usually manageable with over-the-counter pain relief. Most patients find the procedure tolerable and can return to regular activities shortly thereafter.
