Atrial Fibrillation Management and Outcomes

Background Standard treatment for venous thromboembolism is anticoagulation; vena cava filter placement is an alternative in special situations. We aimed to evaluate the outcomes in patients with cancer undergoing filter placement in a cancer center during a 10-year period and assess which preoperatory variables were associated with poorer survival. Methods Retrospective unicenter analysis during a 10-year period was carried out in patients with cancer who had undergone placement of vena cava filter. Early deaths were those that occurred less than 30 days after the filter placement or that occurred during the same hospital stay of the placement. Results About 250 patients were analyzed. About 51.6% were females; 77.2% had proximal lower limb deep vein thrombosis; 34.8% had contraindications to anticoagulation; 32.8% presented bleeding after the onset of anticoagulation; and 18.4% had the filter implanted because they were going to undergo surgery and could not be anticoagulated immediately after. About 51.2% of the filters were removable. However, only 2 had the filter removed. About 59.2% had metastatic disease at the time of filter placement. About 31.2% fulfilled criteria for early death. Of those, 34 patients were put in palliative care after filter insertion (median, 13.5 days). Body mass index >18 kg/m2, the absence of metastatic disease, and filter placement during the same anesthesia of another surgery (especially if elective and curative) were associated with a higher chance of survival. Conclusions Multidisciplinary evaluation (and possibly consideration for palliation) should take place before the decision to insert a vena cava filter in severe oncologic cases depending on overall status. Patients with a greater chance of survival at a 3 or 5 years interval seem to be those whose filters were placed in the perioperative context of other surgeries (specially elective and curative), who were not undernourished, and whose disease was not metastatic at that time. For patients who survived, an active investigation protocol for filter removal should be implemented.
