What is Pigtail Catheter Insertion?
A pigtail catheter is a small-bore drain with a curled tip that is inserted into the pleural space using ultrasound guidance and a guidewire technique. For many effusions and pneumothoraces, it provides effective drainage with less discomfort than a large-bore chest tube.
Why it is done
- Pleural effusions requiring continued drainage
- Pneumothorax
- Selected cases of pleural infection
Before the procedure
- Inform the team about blood thinners and allergies
- Blood tests (including clotting profile) may be checked
- An ultrasound of the chest will be performed to locate the fluid or air safely
- You can usually eat lightly unless sedation is planned
During the procedure
- Local anaesthesia and ultrasound guidance
- Insertion over a guidewire, then secured to the skin
After the procedure
- Drainage monitoring and follow-up imaging
- Removal once drainage is complete
Safety & risks
Pleural procedures are performed with ultrasound guidance and local anaesthesia to improve safety. Possible risks include pain, bleeding, infection, pneumothorax and, rarely, re-expansion pulmonary oedema after large-volume drainage. These will be discussed with you before the procedure.
Preparation instructions may differ for individual patients — please follow the specific advice given at your consultation.
