急性下肢动脉栓塞术后并发急性呼吸窘迫综合征的病因分析

目的 探讨急性下肢动脉栓塞取栓术后并发急性呼吸窘迫综合征的病因。方法对84例急性下肢动脉栓塞取栓术后并发ARDS的病人进行回顾性分析和总结。结果7(8．3％，7／84)例患者行下肢动脉取栓术后诊断为ARDS。5例经机械通气、抗感染、激素冲击及利尿等综合治疗而存活，2例死于多器官功能衰竭。结论缺血-再灌注损伤、全身炎性反应综合征、肺部感染等可能是急性下肢动脉栓塞取栓术后并发ARDS的主要原因。

Etiology of acute respiratory distress syndrome (ards) secondary to postoperation of arterial embolism in lower extermities

To discuss the etiology of ARDS secondary to postoperation of arterial embolism in lower extremities. Retrospectilely analyse the clinical records of 84 patients who had been diagnosed as arterial embolism in lower extremities and treated with thrombectomy. 7(8.3%, 7/84) patients were diagnosed with ARDS after thrombectomy.5(71.4%,5/7) of them cured with the combined treatment such as positive end-expiratory pressure mechanical ventilation, sucking sputum, administration of diuretics, antibiotics and bolus of corticosteroids, etc. 2(28.6%, 2/7) cases died of multiple organ dysfunction syndrome(MODS). Conclusions] Ischemia-reperfusion, systemic inflammation response syndrome and pulmanory infection may be the main cause which lead to ARDS after postoperation of arterial embolism in lower extremities.
