The diagnosis and follow-up of patients with ischemic problems of the arm and hand is facilitated by the selective use of simple noninvasive methods readily available in most vascular laboratories. These tests help differentiate between obstruction and vasospasm and document the severity of the circulatory impairment. Although they may not establish etiology, they often clarify the need for further laboratory tests or arteriography.
大多数血管实验室都能轻易获得一些简单的非侵入性方法，选择性地使用这些方法有助于对手臂和手部缺血问题患者进行诊断和随访。这些检查有助于区分阻塞和血管痉挛，并记录循环障碍的严重程度。虽然它们可能无法确定病因，但往往能明确是否需要进一步的实验室检查或动脉造影。
