RESUMO
Purpose: The aim of the study was to evaluate safety, effectiveness, recurrence rate and 10-year survival after bronchial artery embolization (BAE) in benign and malignant etiologies. Methods: The retrospective study includes 100 BAE procedures in 88 patients. Underlying disease was classified as benign (nâ=â67) and malignant (nâ=â21) etiologies. Immediate bleeding control and procedure safety were evaluated in all patients. In 51 (58â%) patients, follow-up data with a median follow-up time of 1015 days (range, 494 to 3727 days) were acquired to assess overall survival, time-to-recurrence of bleeding and recurrence-free survival, using Kaplan-Maier estimates to compare differences between both subgroups. Results: Immediate bleeding control was achieved after 96/100 procedures (96â%), with a minor complication rate of 5.0â%. No major complications occurred. The overall survival was 74â% after 1 year and 59â% after 5 years and 10 years. There was a significant difference in survival between the malignant and benign groups (pâ<â0.0001). Survival was 90â%, 80â% and 76â% at 1 year, 3 years and 10 years, respectively, in the benign group and 18â% and 0â% at 1 year and 3 years, respectively in the malignant group.âThe median time to recurrence of bleeding and recurrence-free survival were 239 days and 94â% after 1 year and 87â% after 10 years in the benign group, compared to 66 days and 34â% after 1 year and 0â% after 3 years in the malignant group (pâ=â0.0107). Conclusion: BAE is a safe and highly effective treatment option in hemoptysis. However, the recurrence rate and survival are highly dependent on the underlying disease. Key Points: â¢âBAE is a safe and highly effective treatment option in hemoptysis.â¢âRecurrence rate and survival are strongly dependent on the underlying disease with significantly impaired results in patients with malignant diseases. â¢âCoil embolization is an effective BAE treatment method. Nevertheless, it should be mentioned, that reinterventions can be impeded, if embolization is performed in the proximal part of bronchial arteries. Citation Format: â¢âSyha R, Benz T, Hetzel J etâal.
