Vigilance for which vessels is imperative in bronchial artery embolization for hemoptysis?
Anterior spinal arteries arising from bronchial arteries must be identified to prevent nontarget embolization and subsequent paraplegia. Anterior spinal artery branches that arise from bronchial arteries have a classic “hairpin” appearance, traveling cranially for 1 cm or so before forming a loop and doubling back to travel caudally over the midline of the spine.
