To the Editor I read with much interest the article by Goel et al,¹ titled, “Association of Perioperative Red Blood Cell Transfusions With Venous Thromboembolism in a North American Registry.” The authors should be congratulated for their efforts to find causes for postoperative deep vein thrombosis and, eventually, pulmonary embolism. They analyzed data from the American College of Surgeons National Surgical Quality Improvement Program registry regarding 750 937 patients who had surgery in 525 hospitals over a 1-year period. They found that there was a higher incidence of deep vein thrombosis and pulmonary embolism within 30 days from surgery in patients who had received perioperative blood transfusion. About 6.3% of the patients received at least 1 blood transfusion. In a retrospective analysis, they found that blood transfusion was an independent risk factor for thromboembolism and deep vein thrombosis.

对于编辑，我非常感兴趣地阅读了Goel等人的文章，¹标题为“北美注册中心围手术期红细胞输注与静脉血栓栓塞的关系”。应该对作者为寻找术后深静脉血栓形成以及最终导致肺栓塞的原因所做的努力表示祝贺。他们分析了美国外科医生学会国家外科手术质量改善计划注册处的数据，这些数据涉及在1年期间内在525家医院进行过手术的750937名患者。他们发现，接受围手术期输血的患者在手术后30天内深静脉血栓形成和肺栓塞的发生率较高。约6.3％的患者接受了至少1次输血。在回顾性分析中，他们发现输血是血栓栓塞和深静脉血栓形成的独立危险因素。
