In 16 patients with vena cava filters (12 Günther filters, 4 Kimray-Greenfield filters) a follow-up study was performed by ultrasound and abdominal plain film. Ultrasound allows to identify type and location of the filter as well as the entrapment of emboli. Abdominal radiography is useful for exact evaluation of changes in filter position. Combination of sonography and plain films is considered to be most suitable for follow-up studies of caval filters.
对16例植入腔静脉滤器的患者（12例 Günther 滤器，4例 Kimray-Greenfield 滤器）进行了超声和腹部平片随访研究。超声可识别滤器的类型和位置以及栓子的截留情况。腹部X线摄影有助于准确评估滤器位置的变化。超声检查和平片相结合被认为最适合用于腔静脉滤器的随访研究。
