“…Clinical observation in asymptomatic is acceptable; however, long-term safety of observation has yet to be established, to our knowledge. In one publication, three patients at 60 months of follow-up were reported with no complications [57]. Percutaneous retrieval with a snare is often successful, and in symptomatic patients, percutaneous retrieval or surgery is required [56].…”

CT of inferior vena cava filters: normal presentations and potential complications

et al. 2015

With massive pulmonary embolism (PE) being the first or second leading cause of unexpected death in adults, protection against PE is critical in appropriately selected patients. The use of inferior vena cava (IVC) filters has increased over the years, paralleling the increased detection of deep venous thrombosis (DVT) and PE by improved and more available imaging techniques. The use of IVC filters has become very common as an alternative and/or as a supplement to anticoagulation, and these filters are often seen on routine abdominal CT, including in the emergency setting; therefore, knowledge of the normal spectrum of findings of IVC filters by the radiologist on CT is critical. Additionally, CT can be used specifically to identify complications related to IVC filters, and CT may alternatively demonstrate IVC filter-related problems which are not specifically anticipated clinically. With multiple available IVC filters on the US market, and even more available outside of the USA, it is important for the emergency and the general radiologist to recognize the different models and various appearances and positioning on CT, as well as their potential complications. These complications may be related to venous access, but also include thrombosis related to the filter, filter migration and penetration, and problems associated with filter deployment. With the increasing number of inferior vena cava filters placed and their duration within patients increasing over time, it is critical for emergency and other radiologists to be aware of these findings on CT.

“…Some authors report on filter dislocations during the insertion procedure due to early detachment [6,7], a consequence of manipulations by inexperienced surgeons [8][9][10], technical errors (struts do not expand), [8] or other difficulties [11,12]. The internal tension of the cage filter was directed towards the vessel wall and the hooks digging into the cava wall offer protection against dislocation.…”

“…In their series of two cases of atrial and one case of ventricular migration, none of the patients required surgery. 16 One patient died 2 months later for no apparent reason, although the clinical picture was one of massive pulmonary embolism. The two other patients are alive and well 50 months later.…”

ABSTACTOperative retrieval of two proximaily migrated vena caval filters was performed in two patients, ages 42 and 45 years, respectively. In the first patient the filter was encrusted in the right ventricle, and in the second one the filter was found in the pulmonary artery. Both filters were retrieved under cardiopulmonary bypass via an incision in the right atrium and the pulmonary artery, respectively. These two observations underscore the risk of increased unwarranted indications and consequent higher complication rates of vena caval filters.Pulmonary embolism secondary to deep venous thrombosis (DVT) of the lower extremities or pelvis is a significant cause of morbidity and mortality. 1 Anticoagulation treatment is most often effective in preventing the lethal complications of DVT. Placement of a filter in the inferior vena cava (IVC) has been proposed for patients who have recurrent embolism despite adequate anticoagulation therapy or when there are contraindications to heparin. 2,3 Most of the currently available filters can be placed percutaneously in the IVC with no particular difficulty. Complications can arise, however, and may occasionally be severe. Two such severe complications of IVC filter placement are reported herein. CASE REPORTSCase 1. A 42-year-old man sustained a fracture of the right fibula, which was treated by a plaster cast at another hospital. Two weeks later he complained of pain in the right calf. After ablation of the plaster cast, phlebograms demonstrated thrombosis of the right sural and popliteal veins. The inferior vena cavogram was normal. No other clinical findings suggestive of pulmonary embolism, such as thoracic pain or acute dyspnea, were found. There were no contraindications to heparin therapy. In spite of this, the attending surgeon decided to place a vena caval filter via the right jugular vein. However, the filter (Filcard, Filcard International, Lille, France) did not open completely and migrated into the right heart. The patient was then referred to our unit.On admission, hemodynamic parameters were stable. Pulmonary x-ray examination (Fig. 1) showed that the filter was lodged in the right ventricle. Through a midline sternotomy and under cardiopulmonary bypass with induction of ventricular fibrillation, the right atrium was opened longitudinally. The filter was found to be entwined in the papillary muscles and the chordae tendineae of the right ventricle, with two of the hooks penetrating the right ventricular wall. Removal of the filter was difficult because the hooks at the end of each branch were oriented in different directions and the chordae tendineae had to be freed one at a time. After the filter was extracted, the right atrium was closed with a 4/0 continuous polypropylene suture.The postoperative course was complicated by severe bilateral bronchopneumonia that required prolonged intubation and tracheostomy. The patient was discharged 6 weeks later with no tricuspid insufficiency on followup echocardiography.Case 2. A 45-year-old man was admitted for sus...
