Summary
Percutaneous embolotherapy effectively manages life-threatening hemoptysis, especially in patients unsuitable for surgery. This minimally invasive procedure offers a safe and potentially life-saving alternative for controlling bleeding from bronchial and non-bronchial arteries.
Area of Science:
- Interventional Radiology
- Pulmonary Medicine
- Vascular Medicine
Background:
- Life-threatening hemoptysis presents management challenges, particularly for patients with high surgical risks or those refusing surgery.
- Percutaneous embolotherapy offers a less invasive alternative to surgical intervention for hemoptysis control.
Purpose of the Study:
- To assess the efficacy and safety of percutaneous embolotherapy for managing life-threatening hemoptysis.
- To evaluate the role of bronchial and non-bronchial arteries in hemoptysis and the success of embolization.
Main Methods:
- Retrospective evaluation of 16 consecutive patients undergoing percutaneous embolotherapy for severe hemoptysis.
- Selective embolization of bronchial and other identified intrathoracic arteries supplying the bleeding source.
Main Results:
- Percutaneous embolotherapy successfully controlled hemoptysis in all 16 patients.
- Post-tuberculous bronchiectasis was the most common cause; pleural disease was often associated with non-bronchial collateral vessels.
- A single transient complication (paraparesis) was noted; long-term recurrence was managed with conservative treatment, radiotherapy, or surgery.
Conclusions:
- Percutaneous embolotherapy is a safe and effective treatment for life-threatening hemoptysis, particularly in high-risk patients.
- Non-bronchial systemic collateral vessels, especially with pleural disease, are important sources of hemoptysis and should be considered.
- Embolotherapy is a valuable, potentially life-saving option when performed by experienced interventionalists.
