Abstract Introduction: Variation of the ulnar artery in the upper limb is uncommon. The existence of such a variant is of particular clinical significance, as these arteries are more susceptible to trauma, and can be easily confused with superficial veins during medical and surgical procedures, potentially leading to iatrogenic distal limb ischemia. Case report: During routine dissection we observed a unilateral case of superficial ulnar artery in a 60-year-old male cadaver. It originated from the left brachial artery in the middle of the arm, near to insertion of coracobrachialis muscle. From its origin, it passed downwards in the medial part of arm behind the median nerve and forearm in a supericial plane compared to normal ulnar artery. In the hand, the supericial ulnar artery anastomosed with the palmar branch of the radial artery, creating the supericial palmar arch. Brachial artery divided into the radial and common interosseous arteries in the cubital fossa. The normal ulnar artery was absent. The existence of superficial ulnar artery is undeniably of interest to the clinicians as well as to the anatomists.

The principal arteries of the upper limb show a wide range of variation that is of considerable interest to orthopedic surgeons, plastic surgeons, radiologists and anatomists. We present here a case of superficial ulnar artery found during the routine dissection of right upper limb of a 50-year-old male cadaver. The superficial ulnar artery originated from the brachial artery, crossed the median nerve anteriorly and ran lateral to this nerve and the brachial artery. The superficial ulnar artery in the arm gave rise to a narrow muscular branch to the biceps brachii. At the elbow level the artery ran superficial to the bicipital aponeurosis where it was crossed by the median cubital vein. It then ran downward and medially superficial to the forearm flexor muscles, and then downward to enter the hand. At the palm, it formed the superficial and deep palmar arches together with the branches of the radial artery. The presence of a superficial ulnar artery is clinically important when raising forearm flaps in reconstructive surgery. The embryology and clinical significance of the variation are discussed.

Variations of arterial patterns in the upper limb have represented the most common subject of vascular anatomy. Different types of artery branching pattern of the upper limb are very important for orthopedists in angiographic and microvascular surgical practice.The brachial artery (BA) is the most important vessel in the normal vascular anatomy of the upper limb. The classical pattern of the palmar hand region distribution shows the superficial palmar arch. Normally this arch is formed by the superficial branch of the ulnar artery and completed on the lateral side by one of these arteries: the superficial palmar branch of the radial artery, the princeps pollicis artery, the superficial palmar branch of the radial artery or the median artery.After the routine dissection of the right upper limb of an adult male cadaver, we found a very rare variant of the superficial arch artery – a division in a higher level brachial artery. We found this division at 10.4 cm from the beginning of the brachial artery. This superficial brachial artery became a radial artery and was not involved in the formation of the palm arch. In the forearm region, the artery variant was present with the median artery and the ulnar artery, which form the superficial palm arch.

Superficial Ulnar Artery

ABSTRACTAny kind of anatomical variation whether encountered during cadaveric dissections or routine clinical or surgical procedures needs to be reported and taken into account. This can be quite helpful in planning surgeries accordingly and avoid disastrous complications. During routine cadaveric dissection, authors found a superficial course of arteries of the arm as well as the forearm, unilaterally in one cadaver. In this case, there were two brachial arteries - superficial and deep. Superficial brachial artery terminated into superficial radial and superficial ulnar artery. Deep brachial artery was trifurcated into common interosseous, medial and lateral artery branches. Authors have also discussed the developmental anomaly, which could have led to the observed morphological variation. Superficial vessels can provide large size pedicles for raising flaps for local reconstructive surgeries in the region of axilla, elbow, wrist or hand, or other regions.

In this paper, we describe a very rare variant in the course of the ulnar artery that we encountered in dissecting the right upper limb of a 74-year-old man. The ulnar artery arose standardly from the brachial artery in the cubital fossa. However, its ensuing course differed from the norm. The artery entered together with the ulnar vein and median nerve into the pronator canal (between the humeral and ulnar heads of the pronator teres). Further, the ulnar artery descended classically to the ulnar side of the forearm between the flexor carpi ulnaris and flexor digitorum superficialis. Knowledge of this variation in the course of the ulnar artery may have significance in clinical practice because accumulation of anatomical structures in the pronator canal could be a predisposing factor for the compression of nerve or blood vessels. Keywords: anatomical variation; median nerve; pronator canal; pronator teres muscle; ulnar artery.

Superficial Ulnar Artery

A superficial artery may be present in the forearm, arising from the axillary, brachial or superficial brachial arteries and crossing over the origin of the flexor muscles of the forearm to reach the palm (Adachi, 1928; Bergman et al. 1988). When this superficial artery continues as the normal ulnar artery accompanying the ulnar nerve at the wrist, it is referred to as the superficial ulnar artery, with an incidence of ∼4%. When the artery passes below or superficial to the flexor retinaculum in the middle of the forearm, sometimes continuing to join the superficial palmar arch, it is called the superficial median artery, with an incidence of ∼1%. We have observed a relatively rare variation involving the presence of a superficial median artery in both upper limbs. We discuss the clinical importance and the developmental aspects of this arterial variation.

ABSTRACTUpper limb shows a large number of arterial variations. This case report describes the presence of additional superficial ulnar artery which was used to raise a pedicle flap to cover an arm defect thus avoided using the main vessel of the forearm - radial or ulnar artery. Vascular anomalies occurring in the arm and forearm tend to increase the likelihood of damaging the superficial anomalous arteries during surgery. Superficial ulnar or radial arteries have been described to originate from the upper third of the brachial artery; here we report the origin of the anomalous superficial ulnar artery originating from the brachial artery at the level of elbow with the concomitant presence of normal deep radial and ulnar arteries.

Background: The blood supply of the hand is complex and challenging. Awareness of the anatomical variationis necessary not only for the anatomist but also for surgeons.The ulnar artery provides a major blood supply to the hand with the assistance of the radial artery in the form of the superficial palmar arch.The objective of this study was reported a rareanatomical variation of the superficial palmar arch.Materials and Methods: The anatomical variation described was found during routine dissection performed by medical students of second semester in a 75-year-old male embalbed adult cadaver in the laboratory of Morphology of the University of Pamplona.Results and Discussion: In the right hand, the superficial palmar arch only gave rise to two common palmar digital arteries. In the left hand, the arch provided common palmar digital arteries which ran into the first, third and the fourth spaces and one proper palmar digital for the little finger. The arch does not supply the second intermetacarpal space.Conclusions: Less critical knowledge of vasculature of the hand might lead iatrogenic injury during surgery, microvascular surgery for revascularization, replantation and composite tissue transfers.Bangladesh Journal of Medical Science Vol.17(3) 2018 p.496-500
