[Endovascular treatment of massive hemoptysis by bronchial artery embolization: short-term and long-term follow-up over a 15-year period].

OBJECTIVE To present our experience of using arterial embolization for the endovascular treatment of massive hemoptysis along with the results of follow-up over a 15-year period. PATIENTS AND METHODS A total of 401 patients with hemoptysis were referred to the minimally invasive surgery unit of the Hospital Universitario Lozano Blesa de Zaragoza between April 1989 and September 2004 for diagnosis and possible endovascular treatment. Of those patients, 314 met criteria for massive hemoptysis and treatment was attempted using embolization in 287 (91.4%). The most common cause of hemoptysis was bronchiectasis (n=99, 31.5%), followed by lesions due to tuberculosis (n=57, 18.1%) and chronic bronchitis (n=47, 14.9%). RESULTS Angiography of the bronchial arteries provided evidence to account for the hemoptysis in 287 patients (91.4%). The affected arteries were satisfactorily embolized in 281 (97.9%). Endovascular treatment was clinically successful in 256 of those patients (91.1%). Embolization had to be repeated during the hospital stay in 19 patients (6.7%) and was effective in 52.6% of those cases. The 6 patients in whom embolization was not satisfactory underwent thoracotomy. The mean follow-up in 201 patients (71.5%) was 2372.5 days (range, 61-5475 days). Eighty patients (28.4%) were lost to follow-up for various reasons and at different points. Recurrence of hemoptysis occurred on 1 or more occasions in 45 patients (22.3%) but only 21 (10.4%) required repeat embolization. Minor complications that did not require treatment were observed in 88 patients (28.0%). CONCLUSIONS Embolization of bronchial arteries is a nonsurgical treatment that is safe and effective in patients with massive hemoptysis.
