Abstract (2. Language):
The superficial palmer arch is formed by superficial division of ulnar artery and completed on radial side
by either of the superficial palmar branch of radial artery, arteriaprincepspollicis, arteriaradialisindicis or
arterianervimediana. It may be incomplete at times. It lies beneath the palmar aponeurosis and in front of long
flexor tendons, lumbricals and palmar digital branches of median nerve.Awareness of the superficial palmer
arch variation in the hands is essential for surgeons, radiologists and anatomists because of innovative
microsurgical techniques in reconstruction of a traumatized hand, arterial repairs and may be useful for vascular
graft surgeries.Variations in the superficial palmer arch have been studied by several authors.
We intended to study superficial palmer arch in twenty pairs of hands in a course of two years and report the
variations. We dissected forty palms of twenty cadavers over 2 years during routine dissection for undergraduate
teaching in a medical college of Kolkata, India.Bilateral variations of superficial palmer arch were observed in
three pairs of palms. Of them, one pair was complete arch, other two incomplete, though they again differed in
distribution.
With high rate of road traffic accidents in today’s world, and increasing needs of surgical reconstruction
procedures of hand and vascular graft application, it has become essential to acquire knowledge of
anatomical variation of superficial palmer arch. Such knowledge is also essential to have proper
interpretation and performance of the diagnostic angiography and therapeutic surgery in case of
ischemic changes in fingers.
