We compared twenty-five total hip-arthroplasty patients with twenty-five patients who underwent other operations on the lower extremity, with regard to evidence of pulmonary embolism as determined preoperatively and postoperatively from lung perfusion scans, ventilation scans, and pulmonary angiography. Blood gases and serum enzymes also were studied. The over-all incidence of pulmonary embolism was 6 per cent, despite the absence of clinical evidence of that complication. Abnormalities in scans and blood studies were common preoperatively, so that the diagnosis often depended on the detection of additional abnormalities postoperatively.
我们将25例全髋关节置换术患者与25例接受下肢其他手术的患者进行了比较，比较内容为术前和术后通过肺灌注扫描、通气扫描及肺血管造影确定的肺栓塞证据。同时还研究了血气和血清酶。尽管没有该并发症的临床证据，但肺栓塞的总体发生率为6%。术前扫描和血液检查异常很常见，因此诊断往往依赖于术后发现的其他异常情况。
