22/03/2010 Arteries and veins of the upper limb ARTERIES The subclavian artery becomes the axillary artery after crossing the 1st rib ARTERIES & VEINS of the upper limb The axillary artery becomes the brachial artery after crossing the posterior axillary fold The brachial artery divides just distal to the elbow into the radial and ulnar arteries. Marc REVOL, 2010 The ulnar artery gives rise to the common interosseous artery, which divides into anterior and posterior interosseous arteries. The hand is supplied on the palmar aspect by variable anastomoses between branches of the radial and ulnar arteries. www.anato.info 1 Arteries and veins of the upper limb Begins at the distal border of the tendon of teres major Ends about 1 cm distal to the elbow joint by dividing into radial and ulnar arteries.

Pierces the interosseous membrane proximal to pronator quadratus Distally it anastomoses with the posterior interosseous artery and the dorsal carpal arch. Branches : o Median artery o Muscular branches for FDP, FPL, pronator quadratus, and deep extensor muscles o Small cutaneous branches for the lower lateral border of the forearm www.anato.info 13 Arteries and veins of the upper limb www.anato.info 14 Arteries and veins of the upper limb Posterior interosseous artery Begins at the proximal border of the interosseous membrane Passes dorsally between supinator and abductor pollicis longus Descends deep in the groove between extensor carpi ulnaris and extensor digiti minimi Distally it anastomoses with the terminal part of the anterior interosseous artery and the dorsal carpal arch. Branches : o Multiple muscular branches o Fascio-cutaneous branches in the intermuscular septum www.anato.info 15 Arteries and veins of the upper limb www.anato.info 16 Arteries and veins of the upper limb VEINS The venous drainage of the upper limb is composed of superficial and deep vessels. The deep veins accompany the arteries. They are connected to the superficial system by perforating veins. The superficial veins starts on the back of the hand as a dorsal arch. •The cephalic vein begins at the radial extremity of the arch. It ascends along the lateral aspect of the arm, then it pierces the deep fascia to enter the axillary vein just distal to the clavicle. •The basilic vein passes along the medial aspect of the forearm, pierces the deep fascia at the elbow and joins the venae comitantes of the brachial artery •The median cubital vein links the cephalic and basilic veins in front of the elbow. www.anato.info 17 www.anato.info 18 3 22/03/2010 Arteries and veins of the upper limb References Doyle JR, Botte MJ.
