Severe respiratory failure caused by recurrent pulmonary hemorrhage in Takayasu's arteritis

We encountered a 52-year-old man with Takayasu's disease (pulseless disease) and severe respiratory failure due to recurrent pulmonary hemorrhage. Angiography revealed occlusion of multiple branches of the pulmonary artery, which were filled via collateral circulation from the coronary, intercostal, and intermammary arteries. This is a rare case that causes massive pulmonary bleeding and respiratory failure in Takayasu's arteritis.
