Embolisation of pulmonary radio frequency pathway - a randomised trial

Area of Science:

• Interventional Pulmonology
• Medical Device Technology
• Thoracic Surgery

Background:

• Pneumothorax is a common complication of pulmonary radiofrequency ablation (RFA).
• Thoracic drainage placement frequently leads to prolonged hospital stays.
• Minimizing these complications is crucial for patient recovery and healthcare efficiency.

Purpose of the Study:

• To evaluate the efficacy of gelatin torpedoes in reducing pneumothorax after pulmonary RFA.
• To assess the impact of gelatin torpedo embolization on the need for thoracic drainage placement.

Main Methods:

• A prospective randomized study involving 73 patients undergoing pulmonary RFA.
• Patients were divided into two groups: 34 with gelatin torpedo embolization and 39 without.
• Comparison of pneumothorax incidence, volume, and drainage requirements between groups.

Main Results:

• Pneumothorax occurred in 47% of patients with embolization versus 90% without (p < .0001).
• Pneumothorax volume was significantly lower in the embolization group (22.7% vs. 34.1%, p = .02).
• Thoracic drainages were significantly reduced in the embolization group (8% vs. 64%, p < .001).

Conclusions:

• Gelatin torpedo embolization of RFA pathways significantly decreases pneumothorax and thoracic drainage.
• This technique supports therapeutic abstention and non-invasive management strategies.
• Embolization offers a promising method to improve outcomes following pulmonary RFA.
