The effect of a temporary inferior vena cava filter in the treatment of deep vein thrombosis in critically-ill patients.
We studied the clinical courses of patients with deep vein thrombus (DVT) who underwent insertion of temporary inferior vena cava filters (tIVCF) and evaluated the effectiveness of the tIVCF. From January 2003 to March 2008, tIVCF were placed in 12 patients with a diagnosis of DVT in the Intensive Care Unit (ICU) of Gunma University Hospital. The mean age of the patients was 52 +/- 16 years (range, 18-82). Eight were medical patients who had not undergone any prior surgery, and 4 were postoperative patients, including 3 with a malignancy. The diagnosis of DVT was made using enhanced computed tomography. The Toray Neuhaus Protect catheter (6Fr, Toray Medical, Tokyo) was used as a tIVCF in all 12 patients. We evaluated the clinical course of the patients before and after placement of a tIVCF and studied their prognosis. DVT occurred on 15 +/- 9 days after surgery or admission to hospital. Pulmonary thromboembolism (PTE) was detected in 7 patients prior to the placement of a tIVCF, 3 of whom required cardiopulmonary resuscitation. The mean duration of tIVCF placement was 18 +/- 9 days; no episodes of PTE occurred after tIVCF placement. DVT completely or almost completely disappeared during the period of tIVCF placement; subsequently, tIVCFs were successfully removed in 10 patients (83%). A permanent IVCF was placed in only 1 patient, and the tIVCF was removed in the remaining patient because of suspected catheter infection. There were 2 complications related to tIVCF placement: infection at the insertion site and suspected catheter infection. tIVCF placement could prevent the occurrence of PTE without provoking life-threatening complications. The results suggest that tIVCF is useful in the prevention of PTE in patients with DVT.
