Fifty-five patients (33 male and 22 female), 3 to 73 years in age, underwent aortic arch and selective upper extremity arteriography for the evaluation of forearm and hand ischemia from 1971 to 1980. Fifty-one patients had organic occlusive lesions (12 subclavian, 15 axillobrachial, 17 radial-ulnar, and 7 palmar-digital), including distal forearm and hand emboli, as a consequence of proximal occlusive disease in nine patients (5 subclavian, 2 axillobrachial, and 2 radial-ulnar). The remaining four patients had vasospastic disease. Major arteriographic findings of obstructive disease were defined by: morphology of lesions, symmetry or asymmetry of obstructions, segmental versus tandem lesion distribution, and the resultant pattern of collateral circulation. Vasodilatory pharmacoangiography with magnification technique frequently facilitated evaluation of digital and collateral vessels. Therapeutic interventions were dictated by clinical data heavily weighed by the arteriographic examination. Limited arteriographic studies would have been misleading in the evaluation of many patients. |
