Sistema venoso:

As doenças venosas são as mais frequentes, sendo as varizes e as tromboses venosas as de maior incidência. As varizes são veias em membros inferiores que se apresentam dilatadas e tortuosas, podendo levar a sintomas como dor, peso e cansaço. A trombose venosa é a formação de coágulos dentro das veias, que podem se desprender e ir para o pulmão, causando embolia pulmonar.

– varizes, vasinhos, microvarizes, teleangiectasias, varicorragia, rotura de varizes
– úlceras venosas
– tromboflebites e tromboses venosas
– trombofilias (doenças do sangue que causam coagulação aumentada)
