DSA (angiography) - Diagnostic and therapeutic bronchial artery angiography
Oblique Right superior bronchial artery
Oblique Left bronchial artery
Oblique Right inferior bronchial artery
Oblique Right inferior bronchial artery
Bronchial arteries show considerable anatomical variation 4. In this patient, catheterization of the right superior (first image) and left (second image) bronchial arteries showed no bleeding. Subsequent catheterization of a right inferior (third stack) bronchial artery shows subcarinal contrast extravasation. This artery was embolized with glue (fourth image) resulting in successful complete obliteration of the artery and cessation of bleeding. The "shadow image" of the contrast pool on the last image is due to imperfect image subtraction because of patient respiration and the glue being mixed with radio-opaque Lipiodol.
