Recurrent upper limb ischaemia due to a crutch-induced brachial artery aneurysm.

An 83-year old man who had used bilateral axillary crutches for 67 years was referred to our hospital for acute left upper limb ischaemia. He underwent successful recanalization through emergent catheter thromboembolectomy. However, a crutch-induced left brachial artery aneurysm was subsequently detected by computed tomography. Therefore, we performed aneurysm exclusion and subsequent saphenous vein bypass grafting. When a crutch user presents with upper limb ischaemia, a high index of suspicion and early identification of the crutch induced vascular injury are mandatory for appropriate treatment.
