ABSTRACT

El flujo venoso reverso del colgajo sural no ha sido estudiado anteriormente con claridad. El presente estudio tiene como objetivo determinar el trayecto que sigue dicho flujo reverso. Se disecaron cincuenta extremidades pélvicas en veinticinco cadáveres, se inyectó colorante de forma retrógrada en la vena safena externa y se siguió su trayecto. Se encontró que en el 100% de las disecciones, sólo había una válvula a dos centímetros proximal al maléolo lateral, la cual se encarga de desviar el flujo invertido hacia las venas peronéas profundas (AU)


The reverse venous flow of the sural flap has not been clearly reported previously. The aim of the following study is to determine the course that this reverse flow follows. Fifty pelvic extremities of twenty – five corpses were dessected, ind, was injected in a reverse manner in the lesser saphenous vein and its course was followed. In all the corpse dissections done, only one had a valve that was located two cm proximal from the lateral melleolous, which diverts the reverse flow towards the deep peroneal veins (AU)
