Abstract

|
|
Purpose:Inferior vena cava (IVC) filter is commonly practiced to prevent pulmonary embolism during endovascular therapy of deep vein thrombosis (EndoDVT). When the thrombus is trapped inside the filter during intervention, its removal is quite challenging. The purpose of this study is to determine retrieval rates of IVC filter after EndoDVT and its characteristics.
Methods:Patients who underwent EndoDVT in Inha Unversity Hospital from June 2004 to May 2009 were reviewed retrospectively. Retrievable IVC filter was inserted before EndoDVT. EndoDVT was done by catheter directed thrombolysis or pharmacomechanical thrombectomy using urokinase. IVC filter retrieval was decided according to computed tomography after 2 weeks.
Results:126 patients were treated with EndoDVT. Optease (n=101) and Tulip (n=25) IVC filters were inserted. IVC filters were retrieved in 42.9% (54/126). There was no IVC filter related complication during its insertion and removal. IVC filter was not retrieved in 72 patients. Reasons for its failure include residual thrombosis in IVC filter (n=28), high risk for recurrent DVT (n=34), massive pulmonary embolism (n=8), and death (n=2). Residual thrombus inside IVC filter disappeared in 5 patients during 6-month follow up.
Conclusions:IVC filters retrieval rate after EndoDVT was 42.9%. This can be improved by thorough patient follow up and extended retrievability.
