Image-guided fluid collection drainage by catheter (eg, abscess, hematoma, seroma, lymphocele, cyst); visceral (eg, kidney, liver, spleen, lung/mediastinum), percutaneous
CPT4 code
Name of the Procedure:
Image-guided fluid collection drainage by catheter (e.g., abscess, hematoma, seroma, lymphocele, cyst); visceral (e.g., kidney, liver, spleen, lung/mediastinum), percutaneous
Summary
This procedure involves using imaging technology to guide a catheter into a specific area of the body to drain fluid collections such as abscesses, hematomas, seromas, lymphoceles, or cysts. It is performed percutaneously, meaning through the skin, and targets visceral organs like the kidney, liver, spleen, and lung/mediastinum.
Purpose
The procedure is intended to relieve symptoms and prevent complications caused by accumulated fluid within the body. The expected outcome is the reduction of pressure and discomfort, and in cases of infection, the removal of abscess fluid may assist in recovery.
Indications
- Presence of abscesses causing infection or discomfort
- Hematomas leading to pressure and pain
- Seromas following surgery or trauma
- Lymphoceles and cysts causing functional impairments
- Fluid collections detected in visceral organs during imaging studies
Preparation
- Patients may need to fast for several hours before the procedure.
- Adjustments to certain medications, particularly blood thinners, might be necessary.
- Pre-procedure assessments could include blood tests and imaging studies (like CT scans or ultrasounds) to locate the fluid collection accurately.
Procedure Description
- The patient is positioned appropriately and a local anesthesia or sedation is administered for comfort.
- Imaging technology such as ultrasound or CT scans is used to locate the fluid collection.
- The skin is cleaned and sterilized, and a needle is inserted through the skin into the fluid collection under image guidance.
- A catheter is then guided into the area through the needle.
- The fluid is drained through the catheter which may be left in place temporarily to ensure complete drainage.
Duration
The procedure typically takes around 30 to 60 minutes.
Setting
This procedure is usually performed in a hospital or outpatient surgical center equipped with the necessary imaging and sterile environment.
Personnel
The procedure involves interventional radiologists, nurses, and possibly an anesthesiologist depending on the level of sedation required.
Risks and Complications
- Infection at the insertion site
- Bleeding
- Injury to surrounding tissues or organs
- Inadequate drainage requiring additional procedures
- Rarely, allergic reactions to contrast dye or materials used
Benefits
- Relief from discomfort caused by fluid build-up
- Prevention of further complications such as infections spreading or affecting organ function
- Relatively quick recovery with minimal invasiveness
Recovery
- Patients may need to rest for a few hours post-procedure and be monitored for any immediate complications.
- Instructions will include keeping the insertion site clean and dry.
- Follow-up appointments to monitor for recurrence of fluid collections.
- Recovery time is generally quick, with most patients resuming normal activities within a few days.
Alternatives
- Antibiotic therapy alone for abscesses
- Surgical drainage, which is more invasive
- Observation and regular monitoring if the fluid collection is stable and asymptomatic
- Each alternative has its risks and benefits, with image-guided drainage being less invasive and often preferred due to its precision and effectiveness.
Patient Experience
During the procedure, patients might feel slight pressure or discomfort at the insertion site. Post-procedure, some soreness around the catheter area is normal but managed effectively with pain relief measures. Overall, patients usually experience a noticeable reduction in symptoms shortly after fluid drainage.
