A 55-year-old woman with a background of vascular disease presented with signs of bilateral limb ischaemia. Following elective axillobifemoral bypass and hospital discharge, accidental axillary trauma causing a chest wall haematoma, the patient underwent an emergency graft repair. Postextubation, she reported with absent sensation in her legs. Spinal cord infarction was diagnosed through clinical assessment and exclusion of other causes. The aetiology of compromise to the spinal cord blood supply is unclear. Possibilities include intraoperative hypotension, inadvertent compromise to blood supply of thoracic radicular arteries, dislodged atherosclerotic emboli or a combination of these factors. Spinal cord infarction recognised early can be treated. Sedation to assist ventilation had obscured the problem early enough to consider treatment. Patients with vascular risk factors should be carefully managed intraoperatively to minimise hypotensive episodes and care should also be taken not to compromise blood flow of radicular arteries.
一名有血管疾病史的55岁女性出现双侧肢体缺血症状。在择期腋-双股动脉搭桥术后出院时,因意外的腋窝创伤导致胸壁血肿,患者接受了紧急移植修复。拔管后,她报告腿部感觉缺失。通过临床评估并排除其他原因后诊断为脊髓梗死。脊髓血液供应受损的病因尚不清楚。可能的原因包括术中低血压、无意中影响胸段神经根动脉的血液供应、动脉粥样硬化栓子脱落或这些因素的综合作用。早期发现的脊髓梗死可以治疗。辅助通气的镇静作用过早掩盖了问题,以至于无法考虑治疗。有血管危险因素的患者在术中应谨慎管理,以尽量减少低血压发作,同时也应注意不要影响神经根动脉的血流。
