A RARE CASE OF SUPERFICIAL ULNAR ARTERY AND ITS CLINICAL IMPLICATIONS

Superficial ulnar artery (SUA) is defined as arterial variation of an ulnar artery of high origin that lies superficially in the forearm. Because an SUA may be mistaken for a superficial vein, there is a risk of arterial damage. During routine dissection of the cadaver, we incidentally detected a case of unilateral SUA in the left arm. SUA arose from the axillary artery and descended superficial to the axillary artery and median nerve. At the wrist, the SUA crossed over palmaris longus (PL) tendon from the radial side to the ulnar side. In this cadaver, the PL tendon was located on the ulnar side and was thicker than the flexor carpi radialis tendon. Clinicians should check for the presence of SUA before any technical procedure, because lack of awareness of its presence can have serious consequences.

Superficial Ulnar Artery

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.

North Bengal

AbstractIn this rare case, found during routine dissection of head and neck in North Bengal Medical College on the right side of the neck, common carotid artery bifurcated at a higher level than usual and 1.25 cm below the bifurcation, gave a common origin of lingual and superior thyroid artery from its medial side (thyorolingual trunk). No such anomaly was noted on the left side. This type of combination of variations has important clinical implications.
