Major haemoptysis in Hong Kong: aetiologies, angiographic findings and outcomes of bronchial artery embolisation
OBJECTIVE: To provide comprehensive updates on the aetiologies, angiographic findings and outcomes of bronchial artery embolisation (BAE) for life-threatening haemoptysis in Hong Kong.
DESIGN: Retrospective review of clinical records of consecutive patients presenting with life-threatening haemoptysis from 2000 to 2006.
RESULTS: There were 3006 admissions due to haemoptysis involving 2260 patients during the study period; of these, 251 patients had life-threatening haemoptysis. Pulmonary tuberculosis (PTB) (active or inactive) and bronchiectasis were the main underlying causes. BAE was attempted in 167 patients. There was a high prevalence of bilateral bronchial arterial abnormalities (31.7%), presence of abnormal non-bronchial arteries (41.3%) and presence of broncho-pulmonary shunt (38.9%). BAE had a high immediate success rate of 95.7%, with a 5-year recurrence rate of 45.0%. Recurrent life-threatening haemoptysis was independently associated with past history of haemoptysis (P = 0.024), presence of broncho-pulmonary shunt (P = 0.013), and incomplete embolisation (P = 0.002). Complications were uncommon (<5%) and self-limiting.
CONCLUSIONS: In Hong Kong, about one tenth of admissions due to haemoptysis were life-threatening. PTB and bronchiectasis were the major causes. Complications due to BAE were uncommon and self-limiting, with super-selective catheters.
