Vascular Disorders

 

Vascular disorders of the upper-extremity are uncommon, but ones that may have lasting implications. 

Arteries bring oxygenated blood from the heart to the fingertips and veins return the used blood back to the heart and lungs. At the level of the wrist 2 major arteries bring blood into the hand: the radial and ulnar arteries (see Figure 1). Variations in the anatomy are common, though, which may affect the way blood flow ultimately reaches each finger.
