A procedure in which fluid (pleural effusion) or air (pneumothorax) accumulating between the lung and the chest wall is drained through a thin catheter placed under local anesthesia.
Indication
- Spontaneous or traumatic pneumothorax (air collection in the outer layer of the lung)
- Need for continued drainage following tension pneumothorax
- Pleural effusion: heart failure, pneumonia complication (parapneumonic effusion, empyema)
- Malignant pleural effusion (related to lung, breast, or other organ cancers)
- Hemothorax (bleeding after chest trauma or surgery)
- Chylothorax (lymphatic fluid collection)
- Placement of a long-term tunneled pleural catheter for recurrent malignant effusions
Preparation
- Obtaining informed consent and providing information about the procedure
- Complete blood count, coagulation tests (INR, PT), and blood typing
- Chest X-ray and, if needed, thoracic ultrasound and computed tomography
- Review of any anticoagulant or antiplatelet medication and discontinuation with physician approval if required
- IV access and monitoring of vital signs before the procedure
How it's performed
- The patient is positioned sitting upright or semi-reclined; ultrasound may be used to mark the location of fluid or air
- The skin is sterilized and covered with a sterile drape
- Local anesthesia (lidocaine) is applied, usually in the 4th-5th intercostal space along the midaxillary line
- A small incision is made; blunt dissection is used to reach the pleural space, and an appropriately sized catheter is placed and secured with a suture
- The catheter tip is connected to an underwater seal drainage system or a one-way valve bag; drainage volume and any air leak are monitored continuously
- A follow-up chest X-ray after the procedure confirms catheter position and drainage effectiveness
Post-procedure
- Frequent monitoring of vital signs, pain, oxygen saturation, and drainage volume during the first 24 hours
- Daily chest X-ray or imaging based on clinical need
- When the air leak resolves and drainage drops to a minimum, the catheter is removed and the site is closed with a tight suture
- After discharge, urgent evaluation is recommended for shortness of breath, fever, bleeding, or wound drainage
- Patients with a long-term tunneled catheter receive education on home care, hygiene, and drainage technique
Risks
- Bleeding, local hematoma, and intercostal vessel injury
- Rare injury to the lung, heart, or intra-abdominal organs
- Infection (wound, empyema) and abscess around the catheter
- Re-expansion pulmonary edema (when a large effusion is drained too quickly)
- Catheter blockage, dislodgement, or subcutaneous emphysema
FAQ
Will the procedure be very painful?
Because the skin and muscles are numbed with local anesthesia, the main sensation is pressure and tightness. A brief pressure sensation may occur when the pleura is reached; mild sedation can be given if needed.
How long does the catheter stay in place?
It depends on the indication. In pneumothorax it is typically removed once the air leak stops and the lung is fully re-expanded (usually within 2-7 days). In recurrent malignant effusions, a tunneled catheter may be used for weeks to months.
How will my life be affected after the catheter is removed?
Most patients return to their normal activities in a short time. The wound suture is taken out within 7-10 days. Heavy exercise and diving require physician approval.
Can I shower while the catheter is in place?
Brief showers may be allowed when the area is protected with a waterproof cover. However, full immersion such as bathing or swimming pools is not recommended due to the risk of infection. Specifics will be guided by your physician's recommendation.
