The authors describe placement of the LG-Medical filter (B. Braun/Vena Tech, Evanston, Ill.) in four patients with an oversized inferior vena cava. The corrected caval diameter at the level of the most inferior renal vein was greater than 28 mm in each patient. However, in each case the vena cava tapered inferiorly to a segment with a diameter less than 28 mm, and the filter was placed at this site. Filter placement was accomplished without difficulty or complication in all cases. One patient died of underlying disease. The three surviving patients were followed for 119 to 374 (mean 276) days. There was no evidence of filter migration, recurrent pulmonary embolism, occlusion of the venacava, access-site thrombosis or other complication. The authors concluded that placement of bi-iliac filters can be avoided by this technique.
作者描述了在4名下腔静脉过大的患者中放置LG-Medical过滤器（贝朗医疗/威娜泰克公司，伊利诺伊州埃文斯顿）的情况。每位患者最下方肾静脉水平处校正后的腔静脉直径均大于28 mm。然而，在每种情况下，下腔静脉向下逐渐变细至直径小于28 mm的节段，过滤器即放置于此部位。所有病例中过滤器的放置均顺利完成，无困难或并发症。1例患者死于基础疾病。3名存活患者的随访时间为119至374天（平均276天）。没有过滤器移位、复发性肺栓塞、腔静脉闭塞、穿刺部位血栓形成或其他并发症的证据。作者得出结论，该技术可避免双侧髂静脉过滤器的放置。
