In order to help clarify the long-term results of filter implantation and how best to manage the post-operative care, 92 patients with implanted filters were observed for up to 6 years. The follow-up examinations included detailed interrogation, a clinical investigation, plain abdominal radiography in two planes, contrast-enhanced computed tomography of the vena cava and colour-coded duplex sonography of the vena cava and the veins of the pelvic and legs. In the early phase of the study, two patients who received Günther filters in 1988 experienced dislocation of the filter after 3 months. In the later phase, 85% of those treated with oral anti-coagulants and compression showed patent pelvic veins in areas where, at the time of filter implantation, there had been thrombi with the potential to cause embolism. In 72 cases, the inferior v.cava proved to be patent in the area of the filter.
为了帮助阐明滤器植入的长期效果以及如何最好地进行术后护理，对92例植入滤器的患者进行了长达6年的观察。随访检查包括详细询问、临床检查、两个平面的腹部平片、腔静脉增强计算机断层扫描以及腔静脉和盆腔及腿部静脉的彩色编码双功超声检查。在研究的早期阶段，1988年接受Günther滤器植入的两名患者在3个月后出现滤器移位。在后期阶段，接受口服抗凝剂和压迫治疗的患者中，85%在滤器植入时存在可能导致栓塞的血栓的区域，盆腔静脉通畅。在72例病例中，滤器所在区域的下腔静脉被证明是通畅的。
