[Interventional radiology in the treatment of hemoptysis].

Massive haemoptysis, usually related to lesions of bronchial arteries, is a life-threatening complication of chest lesions. Embolization of bronchial arteries demonstrates immediate favourable results in at least 90% of cases. The main complications of embolization of bronchial arteries are medullary strokes. Consequently it is mandatory to visualize the anterior spinal artery in order to avoid its embolization. Massive haemoptysis of pulmonary arterial origin is far less common. It is also feasible to perform the embolization of the abnormal pulmonary artery in order to control the haemoptysis.
