Introduction
Massive hemoptysis is the most feared of all respiratory emergencies, with many underlying causes. In 90% of cases, the source of hemoptysis is the bronchial circulation. Despite high recurrence rates, bronchial artery embolization (BAE) remains the first-line treatment in management of hemoptysis.

Aim
To establish pre-procedure and procedural protocols for BAE.

Material and methods
The study included a total of 50 patients referred to the Department of Radiology for complaints of hemoptysis. Pre-procedure computed tomography (CT) angiography for determination of responsible circulation was performed as a regular protocol except in cases presenting with life threatening hemoptysis. Polyvinyl alcohol (PVA size, 300–500 µm and 500–700 µm) particles combined with gel foam embolization was performed. Successful catheterization and embolization of the targeted vessel was considered technical success and the cessation of hemoptysis to minimal levels was labeled clinical success.

Results
Thirty-two (64%) male and 18 (36%) female subjects comprised the study group. Forty (80%) patients had moderate to severe hemoptysis. Tuberculosis (80%) was the most common etiology. Five patients had severe AV shunting and were embolized with decremental particle size (500–700 µm followed by 300–500 µm) to occlude the bed and then embolize the artery. Technical success was achieved in all the patients, but clinical success was achieved in 40 (80%) patients.

Conclusions
Bronchial artery embolization is a minimally invasive procedure recognized for primary management of hemoptysis. Preprocedure evaluation with CT angiography can add incremental value in management. Usage of decremental particle size is helpful to embolize large AV shunts.
