Clinical Significance
The axillary artery may be safely clamped without endangering the arm, but only in a location proximal to the origin of the subscapular artery. The anastomotic network surrounding the scapula provides an alternate path for collateral circulation to the arm from arteries including the dorsal scapular artery and suprascapular artery.
The right axillary artery is often used as an arterial cannulation site in cardiac surgery, particularly for repair of aortic dissection and replacement of the ascending aorta and aortic arch.

Famous quotes containing the word significance:
“For a parent, it’s hard to recognize the significance of your work when you’re immersed in the mundane details. Few of us, as we run the bath water or spread the peanut butter on the bread, proclaim proudly, “I’m making my contribution to the future of the planet.” But with the exception of global hunger, few jobs in the world of paychecks and promotions compare in significance to the job of parent.”
—Joyce Maynard (20th century)
