Type I two bronchial arteries on the left, and one on the right (intercostobronchial trunk) present in 40% of cases. 

Type II one bronchial artery on the left and one intercostobronchial artery on the right present in 20% of cases. 

Communications between bronchial arteries and systemic vessels are ubiquitous, and can sometimes complicate an embolization procedure. The most commonly seen communication is that of a right intercostobronchial trunk with an anterior medullary artery that contributes to the vascular supply of the spinal cord through the anterior spinal artery. The anterior medullary arteries have a characteristic hairpin configuration, and follow a course...
