The international encyclopaedia of surgery; a systematic treatise on the theory and practice of surgery . sses beneath the pronator radii teres (Esmarch). Ligation of the Radial Artery.—Although the radial artery is smallerthan the ulnar, it directly continues the course of the brachial artery, andruns in a line drawn from the middle of the bend at the elbow to the innerside of the styloid process of the radius. It is superficial in nearly all itscourse. The radial nerve lies on its outer or radial side. It has two venae-comites. Operation in the Upper Third.—Having extended the arm in a supine position,and having raised the superficial veins by compressing them above, make anincision through the skin and superficial fascia, two inches in length, alongthe inner margin of the supinator longus, if this is recognized, or in the linejust indicated. Raise the deep fascia on a grooved director, and divide the forearm somewhat, to relax the muscles; then, drawing the supinatorlongus aside, the sheath of the artery is exposed. Pass the needle from with-out inward (Fig. 487). Fig. Ligation of the radial artery in its upper third. (Sedillot.) Operation in the Lower Third.—Here the artery lies very superficial, be-tween the tendons of the supinator longus and fioxor carpi radialis, and itspulsations are very distinct. The forearm being supine and the hand forciblyextended, to show the flexor tendon, make a light incision, two inches inlength, on the radial side of the flexor carpi radialis tendon. Cautiously DELIGATION OF ARTERIES. 309 raise the cleep fascia on a director, and divide it. This brings into view theartery with its ven?e comites, and the radial nerve lying on its outer orradial side (Fig. 488). The needle may be passed in either direction. Fig. 488.
