Clinically suspect but nonfatal pulmonary embolism followed vein surgery in 16 of 4,080 patients operated on over a 10-year period from 1962 to 1971, an incidence of 0.39%. The presence of superficial thrombophlebitis, previous or recent thromboembolic disease, or chronic deep venous insufficiency was a statistically significant factor in patients who had embolism. Prophylactic postoperative anticoagulant treatment in those with a thrombotic background appears justified.
1962年至1971年的10年间，4080例接受静脉手术的患者中有16例临床疑似但非致命性肺栓塞，发生率为0.39%。浅表血栓性静脉炎、既往或近期血栓栓塞性疾病或慢性下肢深静脉功能不全的存在，在发生栓塞的患者中是具有统计学意义的因素。对有血栓形成背景的患者进行术后预防性抗凝治疗似乎是合理的。
