I would recommend Guyton physiology. He has several very good parts on oedma. The most probable mechanism is ischemia/reperfusion. I would read books on NO, since this has a central part

Thank you! I am interested in understanding the aspects of this condition in order to model it biomechanicaly. I am gratefull for your aid mr Olaussson.

Dear Konstantinos.

Yeia sou!

As a practising surgeon I find the question is not so easy to answer.  Surgeons cut and sew. Wound oedema comes from wound reaction which is basically an acute inflammatory reaction.  in the 1st 24-48 hours there is movement of fluid,  lymphocytes and macrophages  from the blood into the injured tissues. A cascade of biochemical events occurs  involving the local vascular system and immune system,ultimately involving proliferation of collagen 3 which in time converts to collagen 1. 

From a clinical viewpoint oedematous tissue is firm and non-elastic. I am certain that such tissue would be initially ischemic, as Michael says.  From a biomechanical modelling perspective the ultimate mechanisms which Michael details may not be so relevant.  Actually modelling becomes quite complex. Oedema of what? Which operation? Which organ? Which data to use?In our mathematical model of micturition which I think is a simpler project, we had to use cadaveric data for the different structures, collagen, smooth muscle etc which clearly are not the same as live tissue.
