Two out of nine patients in which inferior vena cava interruption was performed with a Günther filter developed a recurrent pulmonary embolism. In both cases, the filter had moved down and the anchoring legs had perforated the wall of the vena cava. The source of the pulmonary embolism was a clotted basket filter. Anticoagulation was given for two weeks in one patient and six months in the other after insertion of the filter, but it had been stopped before the thrombotic event leading to the recurrent pulmonary embolism. The formation of the thrombi had probably been caused by the migration of the filter and the subsequent perforation, which may have been facilitated by the cessation of the anticoagulation.
在接受了 Günther 滤器下腔静脉中断术的 9 名患者中,有 2 名发生了复发性肺栓塞。在这两例中,滤器均已下移,且固定腿穿透了腔静脉壁。肺栓塞的栓子来源是篮式滤器内形成的血栓。一名患者在植入滤器后接受了两周抗凝治疗,另一名患者接受了六个月抗凝治疗,但在导致复发性肺栓塞的血栓形成事件发生前均已停药。滤器移位及随后的穿孔可能导致了血栓形成,而抗凝治疗的停止可能促进了这一过程。
