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

1. A small incision is made to access a lymphatic vessel in the affected extremity.
2. A contrast dye is injected into the lymphatic vessel.
3. X-ray images are taken to track the flow of the dye through the lymphatic vessels.
4. Radiologists interpret the images to identify abnormalities.
5. 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.
