Lymphangiography, pelvic/abdominal, bilateral, radiological supervision and interpretation
CPT4 code
Name of the Procedure:
Lymphangiography, Pelvic/Abdominal, Bilateral, Radiological Supervision and Interpretation
Summary
Lymphangiography is a diagnostic imaging procedure used to visualize the lymphatic vessels and nodes in the pelvic and abdominal areas. This involves injecting a contrast dye and taking X-ray images to identify any abnormalities.
Purpose
Lymphangiography is used to detect issues such as blockages, tumors, or areas of inflammation within the lymphatic system. The main goals are to diagnose certain conditions, plan treatments, and monitor the effectiveness of therapies.
Indications
- Suspected lymphatic system disorders
- Unexplained swelling (lymphedema) in the pelvic and abdominal regions
- Cancer staging and treatment planning
- Assessing lymph node involvement in pelvic or abdominal diseases
Preparation
- Fasting may be required several hours before the procedure.
- Patients may need to stop certain medications, as instructed by their doctor.
- A detailed medical history and possibly a physical examination will be conducted.
- Blood tests or other diagnostic imaging might be done beforehand.
Procedure Description
- The patient is positioned on an X-ray table.
- Local anesthesia is administered to numb the injection site.
- A contrast dye is injected into the lymphatic vessels, usually through a small incision.
- X-ray images are taken of the pelvic and abdominal areas to visualize the lymphatic system.
- Radiologists analyze the images to identify any abnormalities.
- The procedure typically concludes with the removal of the injection materials and applying a bandage to the site.
Duration
The procedure usually takes around 1-2 hours, depending on the complexity and patient's condition.
Setting
Lymphangiography is typically performed in a hospital's radiology or imaging department.
Personnel
- Radiologist (performs and interprets the imaging)
- Radiologic technologist (assists with the imaging process)
- Nurse or medical assistant (provides patient care and preparation)
- Anesthesiologist (if sedation or deeper anesthesia is required)
Risks and Complications
- Allergic reaction to the contrast dye
- Infection at the injection site
- Bleeding or bruising at the injection site
- Pain or discomfort during or after the procedure
- Rare risk of blood clots or deep vein thrombosis
Benefits
- Accurate diagnosis of lymphatic system disorders
- Detailed images that can guide treatment planning
- Helps in assessing the spread of cancer and planning surgeries or other interventions
- Provides important information for monitoring the effectiveness of treatment
Recovery
- Patients are usually monitored for a short time after the procedure.
- They may experience some soreness or bruising at the injection site.
- Drinking plenty of fluids can help flush out the contrast dye.
- Most patients can resume normal activities within a day, but should follow any specific instructions from their doctor.
- Follow-up appointments may be scheduled to discuss the results and plan further treatment if necessary.
Alternatives
- Ultrasound: Non-invasive but may not provide as detailed images.
- MRI with lymphangiographic techniques: Provides high-definition images without X-ray exposure, but is more expensive.
- CT scan: Can be quicker, but involves higher doses of radiation.
- Direct physical examination and lymph node biopsy: Invasive but provides tissue samples for analysis.
Patient Experience
- Patients may feel a brief sting or pinch when the local anesthesia is administered.
- Some discomfort or pressure might be felt during the injection of the contrast dye.
- Post-procedure, most patients experience minor soreness or bruising.
- Pain management strategies include over-the-counter pain relievers and applying cold compresses to the injection site.
- Clear communication with healthcare providers and following all care instructions can enhance comfort and aid in a smooth recovery.
