A prospective comparison of contrast-enhanced computed tomography (CT) and duplex sonography (DS) was performed to examine the Kimray-Greenfield filter in the inferior vena cava (IVC) in the immediate postoperative period. Fourteen patients were studied for five complications: IVC thrombosis, malpositioning, pericaval hematoma, filter angulation, and prong perforation. Our results found CT to be more efficacious because it was a) able to evaluate more patients with fewer technically inadequate scans and b) more definitive in all categories. However, when visualized, DS was as accurate as CT in the evaluation of thrombosis.
为了检查术后即刻下腔静脉（IVC）内的Kimray-Greenfield滤器，我们对对比增强计算机断层扫描（CT）和双功超声检查（DS）进行了前瞻性比较。对14例患者的5种并发症进行了研究：下腔静脉血栓形成、位置不当、腔周血肿、滤器成角和支脚穿孔。我们的研究结果发现CT更有效，因为它：a）能够在技术上不充分的扫描较少的情况下评估更多患者；b）在所有类别中更具确定性。然而，当可以观察到时，DS在评估血栓形成方面与CT一样准确。
