Comparison of the image quality between a complete upper extremity run-off and a CTA of the hand in a 52-year-old patient with HHS, presenting with ischaemia of the fourth and fifth fingers. a A complete upper extremity run-off was first obtained showing a probable occlusion of the UA. b, c CTA of the hand showed a 6-cm-long occlusion of the UA, the patency of the deep branch of the UA (curved arrow), which is fed by the DPA, the occlusion of the ulnopalmar artery of the fifth finger and the distal occlusion of the radiopalmar artery of the fourth finger (arrowheads). d GI providing an overview of the lesions and of the arterial configuration of the hand showing the deep branch of the UA (curved arrow) and the occlusion of the ulnopalmar artery of the fifth finger (arrowhead)
