A complex variation in the superficial palmar arch
Folia Morphol 2006;65(4):406-409.
Abstract
In this article we describe a unique and complex variation in the arterial pattern of
the left hand of a female cadaver. The following variations were found in this
case: a) persistent median artery of the palmar type, terminating in the hand as
the princeps pollicis and radialis indicis arteries; b) the ulnar artery giving only two
common palmar digital arteries; c) the second digital palmar artery without division
into two digital branches and instead supplying only the radial side of the ring
finger; d) absence of the first common digital artery with the contiguous sides of
the second web space supplied by the first palmar metacarpal artery from the
deep palmar arch; e) early bifurcation of the median nerve proximal to the flexor
retinaculum.
