ABSTRACT

Los pacientes anticoagulados crónicamente que son sometidos a cirugías electivas requieren la suspensión temporaria de los antagonistas de vitamina K. El objetivo del presente trabajo fue evaluar la incidencia de eventos tromboembólicos y hemorrágicos en pacientes anticoagulados sometidos a un procedimiento invasivo, aplicando un protocolo de manejo de anticoagulación en el perioperatorio. Se realizó un estudio descriptivo, con datos obtenidos de manera prospectiva, donde se incluyeron mayores de 18 años que ingresaron para la realización de una cirugía electiva. Recibieron sustitución con enoxaparina aquellos con fibrilación auricular(FA) de moderado y alto riesgo de evento tromboembólico, pacientes con reemplazo con válvula cardíaca mecánica(VCM) de moderado y alto riesgo de evento tromboembólico y con tromboembolismo venoso(TEV) de alto riesgo de evento tromboembólico. Se evaluaron los eventos embólicos y hemorrágicos en el perioperatorio. Setenta y ocho recibieron sustitución con enoxaparina en el perioperatorio, edad promedio de 69.4 ± 11.9 años. Veintiocho tenían FA (36.4%), 12 TEV (15.6%) y 37 VCM (48.1%). En el postoperatorio hubo un evento embólico (1.6%) y 12 eventos hemorrágicos (15.4%) de los cuales 10 fueron menores (12.8%) y 2mayores (2.6%). La seguridad de la sustitución con enoxaparina aún es cuestionable, y se deberán esperar estudios aleatorizados, comparando diferentes estrategias de sustitución con heparinas versus la suspensión del tratamiento anticoagulante en el período perioperatorio para una conclusión definitiva.


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 %), 12 had VTE (15.6 %) and 37 had MCV (48.1 %). Postoperatively, 1 embolic event (1.6 %) and 12 bleeding events (15.4 %) were documented, of which 10 were minor (12.8 %) and 2 major (2.6 %). The safety of bridging therapy is still under debate, and we should await the result of randomized studies comparing different strategies of bridging vs. interruption of anticoagulant therapy in the pre-operative period prior to reaching a definitive conclusion.
