Duplex ultrasound and Doppler evaluation of radial artery. Preoperative Doppler evaluation demonstrated normal flow in proximal and mid radial artery (a). Mid distal flow is decreased (b) and stops at thrombus (c). Radial artery beyond the wrist is fed through collaterals (d). Ipsilateral ulnar artery had normal flow (e); however, segmental pressure (f) demonstrated decreased wrist brachial index.

Noninvasive vascular studies showed occlusion of the left radial artery, proximal peak systolic velocity (PSV) of 10 cm/s, and no distal flow at the wrist with absence of digital pressures (Figure 1).
Neurological exam of left-hand post repair. At 2-week postoperative follow-up, the wound is well healed (a). The patient still has weak wrist extension, finger extension at the metacarpophalangeal joint, and thumb extension (2/5 MRC) (b). Thumb adduction, abduction and flexion, finger, and wrist flexion were 4+/5, grasp +4/5, and forearm supination and pronation were intact. Sensation to pinprick and light touch in left hand was intact.

Thumb range of motion, finger and wrist flexion, hand grasp were all 4/5, as well as an intact forearm supination and pronation (Figure 2).
