Control perioperatorio de la anticoagulacion con antagonistas de la vitamina K en cirugía electiva. / [Perioperative control of vitamin K antagonists in elective surgery].

ABSTRACT

Anti-coagulated patients who undergo elective surgery require temporary interruption of vitamin K antagonists. The aim of this study was to evaluate the incidence of thromboembolic events and bleeding complications in anti-coagulated patients undergoing elective invasive procedures by using an institutional management protocol. This was a descriptive study with prospective follow-up that included patients over 18 year old anti-coagulated with vitamin K antagonists, undergoing elective surgery. Those with atrial fibrillation (AF) at moderate and high risk of thromboembolic events, with mechanical heart valve (MCV) at moderate and high risk of thromboembolic events, and patients venous thromboembolism (VTE) at high risk of thromboembolic events received bridging therapy with enoxaparin. Embolic and bleeding events in the pre-operative period were recorded. Seventy-eight received bridging, mean age 69.4 ± 11.9 years. Twenty-eight had AF (36.4
