Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <p>Guidelines describing the perioperative management of antithrombotic therapy in patients requiring temporary interruption of vitamin K antagonists (VKAs) were first published in 2008. The objective of this study is to evaluate the perioperative management of anticoagulation of patients on chronic VKA and the incidence of bleeding and thrombotic complications pre and postpublication of the 2008 American College of Chest Physicians (ACCP) guidelines. A retrospective review of 40 patients on chronic VKA requiring temporary discontinuation of VKA due to an invasive or surgical procedure who were referred to a single haematology practice from January 2006 to June 2010. Demographics, indications of VKA, risk factors for thrombosis, type of procedure, bridging regimen and bleeding complications were recorded pre and post-2008 ACCP guidelines. Sixty-one procedures were performed in 40 patients; 60% were women. Indications for anticoagulation were secondary prevention of venous thrombosis (<italic>n</italic> = 27), arterial thrombosis (<italic>n</italic> = 8) or both arterial thrombosis and venous thrombosis (<italic>n</italic> = 4), and primary prevention of arterial thrombosis (<italic>n</italic> = 1). Twenty patients (50%) had thrombophilia. The most common surgical and invasive procedures were gastrointestinal (33%), gynaecological (15%) and orthopaedic (11%). Bridging regimen with therapeutic-dose subcutaneous low molecular heparin (LMWH) was used in 27 (67.5%) patients, prophylactic-dose LMWH in 12 (30%) and a combination of LMWH therapeutic and prophylactic-dose doses in 11 (27.5%). Three bleeding complications occurred prepublication of the 2008 ACCP practice guidelines, although no bleeding complications occurred after the guidelines were published. Adherence to the 2008 ACCP guidelines for the perioperative management of anticoagulation reduced bleeding complications in patients on chronic VKA treatment.</p> </sec> </abstract>
