“…An increase in filter span may also be a predictor of caval penetration. 14,16 Stiffness of the filter strut is another important contributor because this factor relates to the radial force exerted. Significant filter tilt (>15°) has also been found to increase the rate of filter penetration.…”

“…Although surgical filter retrieval has been reported, 36 conservative management including observation and analgesia is the usual management for non-life-threatening penetrations. 16,37 In patients with organ/structure injury, surgery may be indicated, especially for symptomatic patients in whom conservative management or endovascular retrieval has failed. 38 For example, formal laparotomy is recommended for patients with filter-related gastric bleeding, small bowel volvulus, small bowel obstruction, or life-threatening retroperitoneal hemorrhage.…”

Caval Penetration by Inferior Vena Cava Filters

Background-Limited penetration into the caval wall is an important securing mechanism for inferior vena cava (IVC) filters; however, caval penetration can also cause unintentional complications. The aim of this study was to assess the incidence, severity, clinical consequences, and management of filter penetration across a range of commercially available IVC filters. Methods and Results-The MEDLINE database was searched for all studies showed evidence of organ/structure involvement. Among patients with penetration, 8% were symptomatic, 45% were asymptomatic, and 47% had unknown symptomatology. The most frequently reported symptom was pain (77%, 108 of 140). Major complications were reported in 83 patients (5%). These complications required interventions including surgical removal of the IVC filter (n=63), endovascular stent placement or embolization (n=11), endovascular retrieval of the permanent filter (n=4), and percutaneous nephrostomy or ureteral stent placement (n=3). Complications led to death in 2 patients. A total of 87% of patients (127 of 146) underwent premature filter retrieval or interventions for underlying symptoms or penetration-related complications. Conclusions-Caval penetration is a frequent but clinically underrecognized complication of IVC filter placement.Symptomatic patients accounted for nearly 1/10th of all penetrations; most of these cases had organ/structure involvement. Interventions with endovascular retrieval and surgery were required in most of these symptomatic patients.

“…While migration has been a concern, the distances are small, and clinically significant adverse outcomes are infrequent. Perforation of the IVC was seen in 14.5-24.2% of patients with the previous model of stainless steel Greenfield filters (14,25,26,29), in contrast to 0.6% with the present type filters (18,19,22,(30)(31)(32). We had no such complications, which is comparable to reports with the newfilter.…”

Objective In this prospective, non-controlled observational study, we evaluated the middle-to long-term results of placement of inferior vena cava (IVC) filter devices in Japanese patients.Methods and results In 42 Japanese patients with deep vein thrombosis (DVT) or pulmonary thromboembolism (PTE) who underwent percutaneous insertion of IVC filters, follow-up examinations at fixed intervals of 2 years were performed, and the data was evaluated including complications. There were no fatal complications during IVC filter implantation. About 5 %of patients with an inserted IVC filter developed symptomatic PTE, another 5 %devel-oped asymptomatic PTE. The trapped thrombus was demonstrated in about 22%of the inserted IVC filters. Lower rates of PTEdevelopment, occlusion of IVC, and captured thrombuswere found in the cases whereconcurrent use of anticoagulation therapy with filters was used. Trapped thrombi were found in half of IVC filters inserted prophylactically for proximal femoral venous thrombosis.Conclusion These experiences with IVCfilters suggest that they are safe and effective for the prevention of PTEin the Japanese population.
