RESUMEN
La comprensión del proceso de la coagulación ha progresado durante la última década, evolucionando a partir del concepto según el cual la producción del coágulo se iniciaba por acción de las plaquetas y la activación de uno de los dos sistemas separados, la vía extrínseca y la vía intrínseca, al concepto actual que hace énfasis sobre la vía común y un sistema proteolítico que da lugar a la degradación de los coágulos formados y a la prevención de la formación indeseada de coágulos.
La alteración de este equilibrio cobra especial importancia en los pacientes con trauma craneoencefálico, en quienes -a la luz de los conocimientos actuales- se pueden presentar trastornos de la coagulación que van desde lesiones procoagulantes, en un extremo, hasta lesiones anticoagulantes, en el otro extremo. La meta de los autores es brindar a los clínicos de una guía de evaluación inicial, de seguimiento y, de las posibilidades terapéuticas disponibles en el momento.

ABSTRACT
The understanding of the coagulation process has progressed during last decade evolving from the concept according to which the production of the clot begins by means of the action of platelets and the activation of one of two separated systems, the extrinsic route and the intrinsic route, to the present concept that makes emphasis on the common route and a proteolytic system that give rise to the degradation of formed clots and to the undesired prevention of the formation of the clot. The alteration of this balance receives special importance in the patients with brain trauma in those who to the light of the present knowledge may present upheavals of the coagulation which can go from procoagulating injuries in one end to anticoagulating injuries in the other. The goal of the authors is to provide a clinical guide with initial evaluation, pursuit and therapeutic possibilities available at the moment.
