Case report: therapeutic bronchial artery embolization in a case of Takayasu's arteritis.

The pulmonary arteries are frequently involved in Takayasu's arteritis with a reported incidence of 41-100% in affected individuals. Patients are usually asymptomatic, however, often despite extensive pulmonary involvement. We describe a patient with Takayasu's arteritis who presented with haemoptysis caused by bronchial artery hypertrophy secondary to occlusive pulmonary arterial disease, who was treated by bronchial artery embolization. This is, to our knowledge, the first reported case of haemoptysis secondary to Takayasu's arteritis successfully treated by embolization.
