Abstract：
True aneurysmal degeneration of the inflow artery after arteriovenous fistula ligation is extremely rare. Pain is the most common symptom and surgical treatment by an autologous venous bypass is considered as the treatment of choice with good long-term results. We present a patient with peripheral embolism as first and only symptom leading to the diagnosis of a true aneurysmal degeneration of the entire left radial artery. It was discovered 5 years after the ligation of his radiocephalic fistula. As illustrated by this case, a conservative treatment by antiplatelet and anticoagulation therapy should be considered a satisfying alternative to the standard bypass surgery in patients with anatomical variations (e.g. an incomplete arterial palmar arch) since the latter include a higher risk of postoperative ischemic complications.
摘要：
动静脉瘘结扎术后流入动脉的真正动脉瘤变性极为罕见。疼痛是最常见的症状，通过自体静脉旁路手术治疗被认为是具有良好长期效果的首选治疗方法。我们介绍了一名患有外周栓塞的患者，这是导致诊断整个左桡动脉真正动脉瘤变性的第一个也是唯一的症状。它是在他的放射性头颅瘘结扎后5年发现的。如这个案例所示，对于有解剖变异(例如掌弓动脉不全)的患者,通过抗血小板和抗凝治疗的保守治疗应被认为是标准搭桥手术的令人满意的替代方案,因为后者包括更高的术后缺血并发症风险.
