THE CLINICAL AND DEVELOPMENTAL SIGNIFICANCE OF ULNAR ARTERY VARIATION DURING SURGERIES AND MEDICAL INTERVENTIONS

ABSTRACT

Background – Ulnar artery is a branch of brachial artery,it descends superficially and vertically between the FCU and FDS in lower two third of forearm. Then it passes above the fiexor retinaculum at wrist later forming superficial palmar arch. During routine dissection in S.N Medical College, Agra, an unusual finding was Case Report- identified in both the upper limb of a 60 year old male cadaver. Ulnar artery runs laterally to ulnar nerve and then passes underneath the fiexor retinaculum. Then it joins with the Superficial Branch of Radial Artery to form Superficial palmar arch. Variation of Ulnar artery is uncommon.It is important in surgical cases of Carpal tunnel release surgery, also can be confused with superficial veins during interventions:
