Fifty-six patients scheduled for total hip alloplasty were screened for deep venous thrombosis by means of 99mTc-plasmin scintimetry, 99mTc-plasmin scintigraphy and contact thermography. Investigations were performed on the seventh postoperative day, and a total of 112 legs were examined. Bilateral ascending phlebography was used as reference procedure, and the criteria for deep venous thrombosis were intraluminal filling defects at phlebography. Six patients developed unilateral deep venous thrombosis. All three screening procedures revealed many false positive and several false negative results. The nosographic sensitivity/specificity was 33%/75% for scintimetry, 50%/91% for scintigraphy and 33%/87% for contact thermography, respectively. It is concluded that all three tests are of no value as screening methods for deep venous thrombosis following major elective hip surgery.
对56例计划行全髋关节置换术的患者，采用99mTc - 纤溶酶闪烁显像、99mTc - 纤溶酶闪烁扫描及接触热成像技术筛查深静脉血栓形成。在术后第7天进行检查，共检查了112条腿。双侧上行静脉造影作为参考检查方法，深静脉血栓形成的标准为静脉造影时管腔内充盈缺损。6例患者发生单侧深静脉血栓形成。所有三种筛查方法均显示出许多假阳性和一些假阴性结果。闪烁显像、闪烁扫描及接触热成像的疾病诊断敏感性/特异性分别为33%/75%、50%/91%和33%/87%。得出的结论是，这三种检查作为主要择期髋关节手术后深静脉血栓形成的筛查方法均无价值。
