Variations and clinical importance of the
superficial palmar arch. S.D.U.
Already in 1816, Meckel mentioned two cases of a peculiar variation of the superficial brachioradial artery which bifurcated within the cubital fossa into a thicker lateral branch, obviously a radial artery, and a thinner medial branch, running subcutaneously and terminating in the
superficial palmar arch. This variant should be termed the superficial brachioradiomedian artery (ABMS) [18].
[1] It runs superficial to flexor muscles of front of forearm & continues as
superficial palmar arch in hand.
Association of the absence of Palmaris longus tendon with an anomalous
superficial palmar arch in the human hand.
In the most distal aspect of this zone, the radial artery divides into four branches which anastomose with similar branches of the ulnar artery, providing the vascularization of the hand: (1) the carpal palmar branch anastomoses with a similar branch of the ulnar artery; (2) the superficial palmar branch, which together with the main trunk of the ulnar artery, forms the
superficial palmar arch, that gives the four common digital palmar arteries, (3) the dorsal carpal branch, with a similar ulnar branch, forms the dorsal carpal arch that gives rise to the dorsal metacarpal arteries, and (4) the termination of the RA itself anastomoses with the deep palmar branch of the ulnar artery to form the deep palmar arch.
