An inferior vena cava (IVC) filter is often placed to prevent recurrent pulmonary thromboembolism (PTE), which is a major cause of death in patients suffering from deep vein thrombosis (DVT). There are various complications after placing an IVC filter. The incidence of filter migration, defined as <2-cm displacement from the initial location, is reportedly 1.3% . However, major migration, such as that to the heart, is a rare but life-threatening complication. We herein report a patient who underwent emergent operation for IVC filter migration to the heart. The ALN filter (ALN Implants Chirurgicaux, Bormes les Mimosas, France), which was used in our case, is a hydrodynamic retrievable IVC filter made from AISI 316 L stainless steel. It is characterized by six short legs that can adhere to the IVC wall and three long legs that can stabilize in the central position along the main axis of the vena cava. There is only one case report of major migration in which the ALN filter migrated significantly to the proximal IVC just below the right atrium. This patient had been asymptomatic, and the migration was found on the scheduled day of retrieval large amount of thrombus remained in the right iliac vein with inadequate anticoagulation after IVC filter placement. The migration may have occurred by increased venous pressure in the IVC because of trapping of the thrombus. Because the IVC filter is not enough to manage a large amount of deep vein thrombus, we should routinely begin adequate anticoagulation therapy, including intravenous administration of heparin sodium and oral warfarin potassium, immediately after insertion of the IVC filter as performed after the second operation. OMICS Group International is one of the leading Open Access Publishing houses, which has around 700+ peer-reviewed journals, 50,000+ editorial board members, and highly qualified, expert reviewers to meet the objectives of the Peer-Review Process. OMICS Group International peer-review policies are highly appreciated, accepted and adaptable to the criteria that have been prescribed by the international agencies such as NIH, PubMed etc. OMICS Group International also organizes 3000+ International Scientific Conferences per year globally. There is a great deal of information out there on scientific topics. However, whether it can be trusted or not is a key issue at present. The main question that often emerges in this aspect is about the review process adopted to screen the articles for publication. One of the most acceptable and proven process adopted in majority reputed international journals is peer reviewing.
