A prospective study was carried out to confirm the validity of a predictive index for patients at risk of developing deep vein thrombosis. The index, which correctly identified nine out of 10 patients and incorrectly identified seven out of 52 patients as being at risk, is based on five variable--namely, the euglobulin lysis time, serum concentration of fibrin-related antigen, age, percentage overweight for height, and presence of varicose veins. Thus a population of patients at particularly high risk of developing postoperative deep vein thrombosis may be identified preoperatively by means of this index, so that prophylaxis may be used more rationally.
开展了一项前瞻性研究，以证实一种针对有发生深静脉血栓形成风险患者的预测指标的有效性。该指标能正确识别出10名患者中的9名有风险，却将52名患者中的7名错误地识别为有风险，它基于五个变量，即优球蛋白溶解时间、纤维蛋白相关抗原的血清浓度、年龄、身高超重百分比以及是否存在静脉曲张。因此，通过该指标可以在术前识别出术后发生深静脉血栓形成风险特别高的患者群体，从而更合理地使用预防措施。
