Methods and Materials

We conducted a retrospective review of the histories and interventional studies of 55 patients (40 male, 15 female, median age 57 years; range 16 – 83 years) referred for endovascular treatment of massive hemoptysis over a period of 16 years (June 1995 to June 2011). The patients' underlying diseases were tuberculosis in 21, malignant tumours in 21, bronchiectases in 11 and cystic fibrosis in 2 cases, respectively.

All patients underwent fibre-optic bronchoscopy before intervention.

Arteries that were supposed to supply the bleeding bronchoalveolar sections were embolized with particles or glue in all cases.

The digital subtraction angiographical (DSA) studies were analysed with respect to the morphology of the embolized bronchial arteries.

Empiric embolization is defined as endovascular occlusion of arteries without visible contrast-material extravasation on DSA studies.
