Thirty-nine patients with 46 limbs at risk underwent arterial embolectomy. The overall mortality was 36% (14 patients). Seventeen limbs (37%) had a poor result. The high mortality is related to the severe underlying medical problems. The patients were divided into two groups: those who actually had embolism (n = 25) and those who had acute thrombosis in previously diseased arteries (n = 14). Those finally diagnosed to have embolism had lower mortality (24% versus 57%) and better limb salvage rates (93% versus 6%) when compared to those with thrombosis. However, the two groups are difficult to distinguish preoperatively. The delay from onset of symptoms to the operation varied between a few hours to over a week and this was not related to the outcome. Thirteen percent of the arterial occlusions were in the upper limb. All of these were due to embolism and there was no mortality for this group with all affected arms achieving a good outcome.
39例有46条肢体存在风险的患者接受了动脉取栓术。总体死亡率为36%（14例患者）。17条肢体（37%）预后不良。高死亡率与严重的基础疾病有关。患者被分为两组：实际发生栓塞的患者（n = 25）和先前病变动脉发生急性血栓形成的患者（n = 14）。与血栓形成患者相比，最终诊断为栓塞的患者死亡率较低（24%对57%），肢体挽救率较高（93%对6%）。然而，两组在术前难以区分。从症状出现到手术的延迟时间从几小时到超过一周不等，且这与预后无关。13%的动脉闭塞发生在上肢。所有这些均由栓塞引起，该组无死亡病例，所有受累上肢均预后良好。
