Tunneled Pleural Drain Placement

Background and indications

A tunneled pleural drain (PleurX® type) is a subcutaneously tunneled indwelling catheter enabling intermittent drainage of recurrent pleural effusion at home. It is first-line treatment for recurrent malignant pleural effusion (lung cancer, breast, mesothelioma, pleural carcinomatosis), as an alternative to chemical pleurodesis (talc).

It is also offered for recurrent benign pleural effusions (refractory heart failure, Meigs syndrome, chylothorax) resistant to medical treatment.

Pre-procedure assessment

Assessment includes chest CT (recurrent effusion confirmation, trapped lung exclusion — relative contraindication to pleurodesis), pleural ultrasound (mapping), and coagulation panel.

Procedure

Under local anesthesia and ultrasound guidance, a 5-10 cm subcutaneous tunnel is created on the lateral chest wall. The tunneled catheter (15.5F) is inserted into the pleural space through the tunnel, with a Dacron cuff. Effusion is partially drained (1 L maximum for first session). Patient is educated on home drainage with vacuum bottles. The procedure takes 30-45 minutes.

Results and scientific evidence

The randomized TIME2 trial compared tunneled drain with talc pleurodesis for malignant pleural effusion: both offer equivalent dyspnea control, but tunneled drain reduces hospitalization days (Davies et al., JAMA, 2012; DOI: 10.1001/jama.2012.5535). Spontaneous pleurodesis (pleural auto-symphysis) occurs in 40-60% of cases after 2-3 months of regular drainage, allowing drain removal.

Risks and complications

Infection (2-5%, empyema: < 2%), drain obstruction (5-10%), local pain (10-20%), site leak (5-10%). Tumor tract seeding risk is low (< 1%).

Recovery

Same-day or next-day discharge. Home drainage every 2-3 days (500 mL-1.5 L per session). Regular radiological and clinical follow-up.

Practical information

The procedure is performed as an outpatient or short inpatient stay depending on the case. It is performed by an interventional radiologist, in coordination with the pulmonologist and oncologist.
