Asymptomatic thrombus trapping in vena cava filters: a case series.
The prophylactic use of vena cava filters (VCFs) remains controversial. Class I data supporting the placement of prophylactic VCFs are lacking. In addition, there are concerns regarding the long-term effects of permanent VCF placement in patients with a relatively brief period of thromboembolic risk. Venous thromboembolism can be a lethal event, occurring without a prodrome. Yet, this condition is potentially preventable. The efficacy of VCFs is difficult to determine, as it is likely that when a VCF actually traps a thrombus, the event is clinically asymptomatic. We present three cases of asymptomatic thrombus trapping in VCFs, recognized through incidental radiographic studies.
