Aneurysms of the axillary artery are rare but potentially dangerous lesions that threaten the upper extremity with vascular and neurologic compromise. Most can be treated effectively with surgical excision and vascular grafting. An illustrative case is presented. These aneurysms may arise as pseudoaneurysms secondary to trauma or iatrogenic complications, or as degenerative lesions often secondary to the chronic use of crutches. They may also arise as postobstructive lesions in patients with thoracic outlet syndrome. Signs and symptoms vary with the cause of the aneurysm and may include mass effects with brachial plexus compression and thromboembolic events involving the hands and fingers. Arteriography is the mainstay of diagnosis, and treatment should be considered in most of these lesions as soon as they become apparent to prevent limb loss or dysfunction.
腋动脉瘤罕见但具有潜在危险性，可导致上肢血管和神经功能受损。多数可通过手术切除和血管移植有效治疗。现展示一典型病例。这些动脉瘤可表现为继发于创伤或医源性并发症的假性动脉瘤，或常继发于长期使用拐杖的退行性病变。它们也可作为胸廓出口综合征患者的梗阻后病变出现。其体征和症状因动脉瘤病因而异，可能包括臂丛神经受压的占位效应以及涉及手部和手指的血栓栓塞事件。动脉造影是诊断的主要手段，一旦这些病变明显，多数应考虑治疗以防止肢体丧失或功能障碍。
