Patients who underwent radiographic phlebography were studied to determine the frequency of postphlebographic venous thrombosis. In a group of 23 patients who had negative phlebograms performed with standard contrast agent (60% sodium methylglucamine diatrizoate), nine had positive 125I-fibrinogen leg scans. On repeat phlebography, three had confirmed deep vein thrombosis, six overall developed deep or superficial thrombosis, and three had positive scans without demonstrable thrombi. In a second group of 34 patients studied with the contrast material diluted to 45%, only three developed positive scans, one due to deep venous thrombosis and two to superficial thrombosis. There was also a reduction in the incidence of postphlebographic symptoms of pain, tenderness, and erythema, but no apparent sacrifice in diagnostic accuracy.
对接受X线静脉造影的患者进行研究，以确定静脉造影后静脉血栓形成的发生率。在一组23例接受标准造影剂（60%甲基葡胺双醋碘苯酸钠）进行静脉造影结果为阴性的患者中，9例125I-纤维蛋白原腿部扫描呈阳性。再次进行静脉造影时，3例确诊为深静脉血栓形成，6例总体上发生了深静脉或浅静脉血栓形成，3例扫描呈阳性但未发现血栓。在另一组34例使用稀释至45%的造影剂进行研究的患者中，只有3例扫描呈阳性，1例因深静脉血栓形成，2例因浅静脉血栓形成。静脉造影后疼痛、压痛和红斑症状的发生率也有所降低，但诊断准确性没有明显下降。
