Abstract:
1. Arterial trunk: Based on the developmental variations, the arm arterial trunksmay be divided into double trunk, single trunk and transitional patterns. The single trunkpattern appears in 87. 06% of 340 sides. The superficial brachial artery is present in28.53%, among which 2.177% of them divide into radial and ulnar arteries in the fore-arm. The superficial radial artery is only present in both arms of 1 body in 170 cases.In 3.74% of 374 sides the median artery extends into the palm. The caliber ofthe arterial trunk in the forearm diminishes from the elbow to the wrist At the elbowthe caliber of the ulnar artery is larger than that of the radial artery and vice versa atthe wrist. 2. Arterial branches: The brachial profundal artery and the superior ulnar col-lateral artery originate directly from the axillary or brachial artery in 47.88% of 330sides. The mean distance between the origin of the inferior ulnar collateral artery andthe bifurcation of the brachial artery is 6.94 cm. in 224 sides. The origins of the recur-rent ulnar artery and the interossous artery stand side by side. The anterior and posteriorulnar recurrent arteries originate separately from the ulnar artery in 18.67% of 225sides. The common interosseous artery is present in 85.15% of 330 sides, among whichthe recurrent interosseous artery originating from the common or posterior interosseousartery in 43.94% and 41.21% respectively.
