In order to determine the incidence of pre-operative and postoperative deep venous thrombosis (DVT) in patients not receiving prophylactic anticoagulant therapy, bilateral phlebography was performed in a prospective study pre-operatively and on the 9th postoperative day, in 51 consecutive patients submitted for major abdominal surgery. The presence of a DVT before surgery was demonstrated in 15.7 per cent of the patients. This high frequency confirms objectively the rationale of starting prophylactic anticoagulant therapy before the surgical procedure. Thrombi were demonstrated postoperatively by phlebography in 54.9 per cent of the patients. Thus the true incidence of DVT induced by surgery was 39.2 per cent taking into account the 15.7 per cent pre-operative DVT rate.
为了确定未接受预防性抗凝治疗的患者术前和术后深静脉血栓形成（DVT）的发生率，对51例连续接受腹部大手术的患者进行了前瞻性研究，术前及术后第9天进行了双侧静脉造影。15.7%的患者术前存在DVT。这一高发生率客观地证实了在手术前开始预防性抗凝治疗的合理性。术后静脉造影显示54.9%的患者有血栓形成。因此，考虑到15.7%的术前DVT发生率，手术诱发DVT的真实发生率为39.2%。
