“…(Sirisha, et al, 2015) The term superficial ulnar artery is applied to an artery which arises from the axillary, brachial or superficial brachial arteries and courses over the origins of the superficial forearm muscles to join at the midlevel of the forearm with the ulnar artery, sometimes replacing it. (Reddy & Vollala, 2007) In the present study we found two limbs where the ulnar artery after originating from the brachial artery had a superficial course in the forearm, and since only the ulnar artery had a superficial course it cannot be termed as a brachioulnoradial artery as described by Rodriguez-Niedenfuhr et al (2001).…”

Introduction: Blood supply to the arm and forearm is conveyed by the brachial artery and its branches, the radial and the ulnar artery. Variations in these arteries are being increasingly reported in many studies. Most of these variations observed are mostly in the course and branching pattern of these arteries and have been accounted to be due to developmental defect, from varied causes. Materials and Methods: In the present study dissection was done on fifty seven upper limb specimens obtained from the college of Medicine and Health Sciences, Oman. Variations observed in the origin and course of the arteries in the arm and forearm, were noted and later photographed. Results: Out of the fifty seven upper limb specimens studied variations were noted in four limbs. In one limb there was a superficial branch originating from the brachial artery, that later divided into superficial radial and ulnar arteries. In two limbs the brachial artery was superficial to the median nerve, in one of them the brachial artery coursing superficial to the median nerve had a tortuous course. Superficial course of ulnar artery in the forearm was noted in another limb. Conclusion: Surgical procedures are being increasingly done on the upper limb arteries, these procedures are either diagnostic or therapeutic interventions, such as arteriography, flap harvesting, creating arteriovenous fistulas etc. Knowledge of the variations in the upper limb arteries is essential before any surgical intervention is planned in the upper limb arteries in order to prevent unnecessary complications.

“…They suggest that radial artery acquires its final state by stage 21 of the embryo and any variations in the formation of SPA may be due to persistence or enlargement of initial network of vessels which normally regress or remain as capillaries. Embryological basis for high origin of superficial ulnar artery and its contribution in the formation of SPA has been reported by Natsis et al (2006) and Reddy &Vollala (2007). Ikeda et al, (1988) also suggest that an inhibition of the development of the vessels at different stages of the embryonic period may be the causes of arterial congenital anomalies.…”

The vasculature of the hand has been a topic of anatomical interest because of wide range of variations in the formation and distribution of palmar arches. In the present study we have emphasized on the varying pattern of the formation and branching pattern of the superficial palmar arch (SPA) in cadaveric human hands. The study was conducted in 42 formalin fixed human cadaveric hands and different presentations were noted. The classic formation of the SPA was noted in 76.6% of the specimens and mostly on the right hand. The other variants noted were SPA completed by the first dorsal metacarpal artery and SPA formed between median and ulnar artery. Incomplete SPA ending in the thenar muscles and an abrupt end between the index and middle finger were also noted in the present study. The existence of both common and rare anatomic variations in the formation of superficial palmar arch as well as the absence of collateral circulation between ulnar and radial arteries necessitates the proper knowledge of vasculature of the hand in order to avoid or minimize the risk of complications during vascular surgeries or reconstructive surgeries in the hand.
