This case report describes a 52-year-old male patient, with the incidental finding of inferior vena cava filter (IVCF) fragments impacted into the right ventricle, secondary to IVCF fragmentation and subsequent embolization. While IVCFs are prescribed to prevent pulmonary embolizations when anticoagulation is either contraindicated, or has failed, IVCF embolizations to the heart represent an extremely rare, but potentially life-threatening complication. Of note, at the time of writing, the utility and effectiveness of IVCF are not fully established. Intracardiac embolizations of IVCF typically present with complications such as hypotension, cardiac tamponade, arrhythmias, ventricle perforation, bleeding, cardiac arrest, and death. To our knowledge, this is the first case report of an asymptomatic kidney transplant recipient found to have right ventricle embolizations of IVCF fragments through routine assessment. Additionally, this is also the first report of an asymptomatic patient who presented IVCF fragments embolized to the right ventricle and left gonadal vein in the same clinical setting.
本病例报告描述了一名52岁男性患者,偶然发现下腔静脉滤器(IVCF)碎片栓塞至右心室,继发于IVCF碎裂及随后的栓塞。虽然IVCF用于在抗凝治疗禁忌或失败时预防肺栓塞,但IVCF栓塞至心脏是一种极其罕见但可能危及生命的并发症。值得注意的是,在撰写本文时,IVCF的效用和有效性尚未完全确立。IVCF的心内栓塞通常伴有低血压、心脏压塞、心律失常、心室穿孔、出血、心脏骤停和死亡等并发症。据我们所知,这是首例通过常规评估发现无症状肾移植受者存在IVCF碎片栓塞至右心室的病例报告。此外,这也是首例在同一临床情况下出现IVCF碎片栓塞至右心室和左性腺静脉的无症状患者的报告。
