Selective catheterization of a hypertrophic right bronchial artery in a 56-year-old man with two episodes of severe hemoptysis. Bronchoscopy detected only some blood trails and clots in the right bronchial system, without conclusive evidence as to the origin of bleeding. Selective angiography of a hypertrophic right bronchial artery through a 5F cobra catheter demonstrates moderate hypervascularity, more prominent in the right upper lobe.
