Resumen
El embarazo se asocia a múltiples cambios fisiológicos y anatómicos que llevan a un estado protrombótico. Este estado incrementa 5 veces el riesgo de tromboembolismo venoso. Además, durante el periodo de gestación y puerperio existen otras condiciones, independientes o relacionadas con el embarazo, en las cuales la tromboprofilaxis farmacológica o la anticoagulación están indicadas. El iniciar la terapia anticoagulante en la mujer embarazada implica un balance de riesgos y beneficios para la madre y el feto así como consideraciones especiales según el tiempo de gestación. La heparina de bajo peso molecular es el tratamiento de elección en la mayoría de las indicaciones, sin embargo, existen casos en los que la warfarina o los anticoagulantes orales directos son de utilidad y están indicados como primera línea.
