Background: Hemoptysis is a common symptom associated with chronic pulmonary aspergillosis (CPA). While surgery is the primary choice to manage hemoptysis, it is often avoided because patients with CPA are more likely to have complications such as respiratory insufficiency and low pulmonary function. Bronchial artery embolization (BAE) may be considered one of the treatments of massive and persistent hemoptysis for such patients.
Methods: We retrospectively reviewed medical records of 41 patients, admitted to National Hospital Organization Tokyo National Hospital, Tokyo, Japan with hemoptysis arising from CPA between January 2011 to December 2016, who were considered inoperable and had undergone BAE.
Results: Out of the 41 cases analyzed in this study, 21 (51.2%) developed rebleeding after BAE within the mean follow-up duration of 24 months. The non-rebleeding rate of patients after BAE was 92.7% within a month and 65.8% within a year. Patients who developed rebleeding had significantly more non-bronchial systemic arteries responsible for the bleeding compared with patients who did not develop rebleeding (mean of 2.55 vs. 4.86, respectively, P = 0.011). Patients with stable or improved radiological findings demonstrated significantly lower rebleeding rates than those with radiological deterioration (P < 0.001). The non-rebleeding patients had significantly better survival than those with rebleeding (79.7% vs. 39.9% over 5 years, P = 0.046).
Conclusions: Bronchial artery embolization was effective in controlling hemoptysis in patients with CPA, especially those who could not undergo surgical resection. However, disease control of CPA was important to prevent rebleeding over the long term and to improve survival after BAE.
