Physical examination may reveal swelling and tenderness around the radial edge of the hypothenar eminence and in the region of Guyon’s canal. A palpable thrill or pulse over the ulnar artery in the canal, digital color and temperature changes, and skin and nail-bed lesions (including petechiae and flame hemorrhages resulting from thrombus embolization) may be seen. Digital color, temperature, and sensory changes may be dramatic in appearance if the patient does not have good collateral flow from the ulnar artery-dominant superficial palmar arch or the radial artery-dominant deep palmar arch or if there is extensive thrombosis throughout the arches.
