Abstract

There is an infrequent disposition of the first metacarpal artery which results in an anastomosis with the common palmar digital artery of the second space, forming an anastomotic system between the deep radial system and the superficial ulnar system. The radial system in turn, through the first dorsal interosseous artery, anastomoses with a collateral of the common palmar digital artery of the second space, ending as the ulnar palmar digital artery of the thumb and establishing a second anastomotic system. A third anastomosis is established in one case, between the common palmar digital artery of the fourth space and the fourth metacarpal artery. To this may be added the classic anastomosis between the superficial branch of the ulnar artery and the deep branch of the radial artery, i.e. the deep palmar arch.
