Sclerotherapy of a fluid collection (eg, lymphocele, cyst, or seroma), percutaneous, including contrast injection(s), sclerosant injection(s), diagnostic study, imaging guidance (eg, ultrasound, fluoroscopy) and radiological supervision and interpretation
CPT4 code
Name of the Procedure:
Sclerotherapy of a Fluid Collection (e.g., Lymphocele, Cyst, or Seroma)
Common names: Sclerotherapy, Percutaneous Sclerotherapy
Summary
Sclerotherapy is a minimally invasive procedure used to treat fluid collections such as lymphoceles, cysts, or seromas. A special solution called a sclerosant is injected into the fluid collection, causing it to shrink and eventually dissipate. Imaging techniques like ultrasound or fluoroscopy are used to guide the procedure.
Purpose
Medical Condition: Lymphoceles, cysts, seromas, or other fluid collections that may cause discomfort or other complications.
Goals/Outcomes: The primary goal is to reduce or eliminate the fluid collection, relieve symptoms, and prevent recurrence.
Indications
Symptoms/Conditions:
- Persistent or growing fluid collections
- Pain or discomfort due to the fluid accumulation
- Risk of infection or other complications from the fluid collection
Patient Criteria:
- Confirmed diagnosis of a fluid collection (lymphocele, cyst, or seroma)
- No contraindications for the use of sclerosant
Preparation
Pre-Procedure Instructions:
- May need to fast for a few hours before the procedure
- Adjustments to certain medications as instructed by the healthcare provider
- Pre-procedure diagnostic tests like blood work or imaging studies
- Inform the healthcare team about any allergies, especially to contrast agents or anesthesia
Procedure Description
- Step-by-Step: The patient is positioned comfortably, and the area around the fluid collection is cleaned and sterilized. Local anesthesia is administered. Using imaging guidance such as ultrasound or fluoroscopy, a needle is inserted into the fluid collection. Contrast dye may be injected to outline the area. The fluid is aspirated, and the sclerosant is injected into the cavity. The process may be repeated to ensure the fluid is properly treated.
- Tools/Equipment: Needle, syringe, sclerosant solution, ultrasound or fluoroscopy machine
- Anesthesia/Sedation: Local anesthesia is typically used; in some cases, mild sedation may be administered
Duration
The procedure typically takes about 30 to 60 minutes.
Setting
This procedure is usually performed in a hospital radiology department or an outpatient clinic equipped with imaging facilities.
Personnel
- Interventional radiologist or a similarly trained physician
- Radiology technologist
- Nursing staff
- Anesthesiologist or nurse anesthetist (if sedation is used)
Risks and Complications
Common Risks:
- Mild to moderate pain or discomfort at the injection site
- Infection
- Allergic reaction to the sclerosant or contrast dye
Rare Complications:
- Severe infection or abscess formation
- Damage to surrounding tissues or organs
- Blood clots
Management:
- Monitoring for signs of infection
- Pain management
- Follow-up appointments to assess efficacy and any complications
Benefits
Expected Benefits:
- Reduction or complete elimination of the fluid collection
- Relief from associated symptoms such as pain or discomfort
- Usually noticeable improvement within a few days after the procedure
Recovery
Post-Procedure Care:
- Rest and limit physical activity for the first 24-48 hours
- Monitor the injection site for signs of infection (redness, swelling, increased pain)
- Over-the-counter pain relievers as needed
- Follow-up imaging to ensure the fluid collection has adequately resolved
Expected Recovery Time:
- Most patients can resume normal activities within a few days
- Full recovery might take 1 to 2 weeks
Follow-Up:
- Regular follow-up appointments to monitor progress and ensure no recurrence
Alternatives
Other Treatment Options:
- Aspiration without sclerotherapy
- Surgical drainage or removal
- Observation for smaller, asymptomatic fluid collections
Pros and Cons:
- Aspiration alone: May be less invasive but has a higher risk of recurrence
- Surgical options: More invasive with longer recovery but definitive in removing the fluid collection
- Observation: Suitable for small, non-symptomatic collections but does not address larger or symptomatic issues
Patient Experience
During Procedure:
- Slight discomfort from local anesthesia and needle insertion
- Mild pressure or stinging sensation when the sclerosant is injected
- Possible temporary pain or cramping in the treated area
After Procedure:
- Mild soreness or bruising at the injection site
- Pain relief measures include rest, ice packs, and pain medication as needed
- Gradual return to normal activities with adherence to post-care instructions
By following the healthcare team's instructions and attending follow-up appointments, patients can help ensure a smooth recovery and effective resolution of the fluid collection.
