The accuracy of our clinical vascualr laboratory was evaluated. Sixty-nine limbs (55 patients) were examined clinically for thrombophlebitis. All of these patients were then evaluated using segmental plethysmography and Doppler ultrasound techniques. Each limb was then studied with venography. In 57 of the 69 (82.6%) limbs evaluated, measurement of the maximum venous outflow accurately reflected the venographic findings. Doppler augmented venous sounds were correct when compared to venography in 77.6% of limbs. In the 59 limbs that exhibited clinical signs of deep venous thrombosis, only 35.6% had venographic confirmation of the diagnosis. The clinical vascular laboratory provides an accuracy of diagnosis of deep venous thrombosis not achieved by clinical examination. If both segmental plethysmography and Doppler ultrasound were negative, it was very unlikely that deep venous thrombosis had occurred.
我们对临床血管实验室的准确性进行了评估。对69条肢体（55名患者）进行了血栓性静脉炎的临床检查。随后，使用节段性体积描记法和多普勒超声技术对所有这些患者进行了评估。然后对每条肢体进行静脉造影研究。在评估的69条肢体中的57条（82.6%）中，最大静脉流出量的测量准确反映了静脉造影结果。与静脉造影相比，77.6%的肢体中多普勒增强静脉音是正确的。在表现出深静脉血栓形成临床体征的59条肢体中，只有35.6%经静脉造影确诊。临床血管实验室提供了临床检查无法达到的深静脉血栓形成诊断准确性。如果节段性体积描记法和多普勒超声均为阴性，则深静脉血栓形成发生的可能性极小。
