Real-time ultrasound-guided pigtail catheter chest drain for complicated parapneumonic effusion and empyema in children - 16-year, single-centre experience of radiologically placed drains.

BACKGROUND

Chest tube drainage with fibrinolytics is a cost-effective treatment option for parapneumonic effusion and empyema in children. Although the additional use of ultrasound (US) guidance is recommended, this is rarely performed in real time to direct drain insertion.

OBJECTIVE

To evaluate the effectiveness and safety of real-time US-guided, radiologically placed chest drains at a tertiary university hospital.

MATERIALS AND METHODS

This was a retrospective review over a 16-year period of all children with parapneumonic effusion or empyema undergoing percutaneous US-guided drainage at our centre.

RESULTS

Three hundred and three drains were placed in 285 patients. Treatment was successful in 93% of patients after a single drain (98.2% success with 2 or 3 drains). Five children had peri-insertion complications, but none was significant. The success rate improved with experience. Although five patients required surgical intervention, all children treated since 2012 were successfully treated with single-tube drainage only and none has required surgery.

CONCLUSION

Our technique for inserting small-bore (≤8.5 F) catheter drains under US guidance is effective and appears to be a safe procedure for first-line management of complicated parapneumonic effusion and empyema.
