The deep palmar arch is the terminal branch of the radial artery, usually forming an anastomosis with the ulnar artery 1.
The radial artery enters the palm in between the oblique and transverse heads of adductor pollicis muscle, coursing across the palm approximately 1 cm proximal to the superficial palmar arch 1. Unlike the superficial palmar arch, the deep arch is usually complete, meaning it almost always forms an anastomosis with the ulnar artery 1-3.
The arch gives rise to three palmar metacarpal arteries, which anastomose with the common palmar digital arteries from the superficial arch around the metacarpal heads 1.
