Abstract

<p>Introduction: There are no recommendations of the indication regarding the placement of a inferior vena cava (IVC) filters in preventing pulmonary embolism (PE) and deep vein thrombosis (DVT). The aim of the current study was to assess indications for filter placement, outcomes and complications, in our institution. Materials and Methods: There were two groups of patients, those who received IVC filters for PE or DVT (A group) and those with past history of DVT or PE who received IVC filters to prevent new PE in surgery (B group) between November 2001 and January 2009. In A group, there were filters placed in 54 patients (28 women and 26 men). Mean age was 61 years. In B group, there were 17 filters placed in 17 patients (11 women and 6 men). Mean age was 52 years. Seventy-eight filters (46 temporal filters, 31 retrievable filters and one permanent filter) were placed in the IVC. Results: There were no patients with worse DVT or symptomatic PE during placement and retrieval. Guenther Tulip™ was used to deploy permanently in 9 patients of 55 patients who received IVC temporal filters. Clinical indications for permanent filter placement were as follows: the capture of thrombus in filter in 4 patients, prolonged bed rest in 3 patients, and etc. The thrombus was attached in the retrieved filter in 12 patients. There were no complications associated with placement of retrievable filters. For temporal filters, there were 6 complications (one catheter fracture, one venous reflow disturbance, one retrieving a filter, one insertion site phlebitis and 2 filters migration). Discussion: There were some complications associated with placement of temporary filter, because of structural problems, so the retrieved filter is recommended for use to prevent PE. The complications of filter placement are decreasing in last two years, but it was suggested that this filter migration is attributed to the care in which artery or venous catheter devices like the temporary filter device are not often used. Conclusion: The IVC filter placement for the prevention of PE will be approved in high-risk patients with proximal deep vein thrombosis and/or high-risk surgery, in that case that a patient, one’s family and the attending physician accept the placement.</p>
