Abstract：
Acute upper limb ischemia is a rare, potentially limb- or life-threatening vascular emergency that may lead to limb dysfunction or amputation. We present a patient undergoing maintenance hemodialysis who was hospitalized for arteriovenous graft thrombus complicated by acute upper limb ischemia arising from thrombus shedding to the fingertip arteries during thrombolysis. We successfully restored fingertip arterial patency, avoided amputation, and recovered the function of the arteriovenous graft by precise thrombolysis, anticoagulation, correction of arteriospasm, and percutaneous transluminal angioplasty. This case provides a basis for vascular access surgeons to treat acute upper limb ischemia caused by thromboembolism similarly.
摘要：
急性上肢缺血是一种罕见的，可能导致肢体功能障碍或截肢的潜在肢体或危及生命的血管急症。我们介绍了一名接受维持性血液透析的患者，该患者因溶栓期间血栓脱落至指尖动脉而引起的急性上肢缺血而住院。我们成功恢复了指尖动脉通畅,避免截肢,并通过精确溶栓恢复了动静脉移植物的功能，抗凝,纠正动脉痉挛，和经皮腔内血管成形术.该病例为血管通路外科医师治疗由血栓栓塞引起的急性上肢缺血提供了依据。
