Abstract:
A high origin of the radial and ulnar arteries was found in the right upper limb of a 72-year-old Thai female cadaver during routine dissection for undergraduate class of Physiotherapist students. The brachial artery is a very short, artery that divides into the radial and ulnar arteries at the upper third of the arm. We determined the length from axillary artery to brachial artery, then from brachial artery to the bifurcation. We also measured the diameter of brachial, radial and ulnar arteries by wrapping the string around them. The length of right axillary artery is 8.8 cm, the length of right brachial artery from its origin to cubital fossa is 9.5 cm. The diameters of right brachial, radial and ulnar arteries are 0.64 cm, 0.32 cm and 0.48 cm respectively. In fact, the variation did not cause atrophy or shrinkage of neighboring muscles or cause of death. This report may remind or aware for surgeons, clinicians and nursing staff or diagnosis and planning of operative treatment of forearm and hand surgeries.
