Acute ischemia of the extremity may be due to arterial occlusion from spontaneous thrombosis, embolus, arterial bypass graft thrombosis, trauma, or spasm. The presence of occlusion or stenosis can be determined noninvasively with the use of duplex Doppler ultrasonography. Most patients will require arteriography prior to thrombolytic or surgical therapy. New techniques, such as percutaneous aspiration thrombolectomy, expand the role of radiologic percutaneous therapy of the acutely ischemic limb. Prompt diagnosis and therapy are required to avoid limb loss or systemic metabolic complications from reperfusion of a dying limb.
肢体急性缺血可能是由于自发性血栓形成、栓子、动脉搭桥移植血栓形成、创伤或痉挛导致的动脉闭塞所致。使用双功多普勒超声可无创确定是否存在闭塞或狭窄。大多数患者在进行溶栓或手术治疗前需要进行动脉造影。诸如经皮抽吸血栓切除术等新技术扩大了急性缺血肢体放射介入治疗的作用。需要及时诊断和治疗，以避免肢体丧失或濒死肢体再灌注引起的全身代谢并发症。
